admin — Mon, 30 Jan 2012 01:52:30 +0000

Plastic Wash Bottles — generally small plastic bottles with a removable pointed tip–can be useful in a wide variety of ways. You can fill them with chocolate or caramel sauce to drizzle over your favorite desserts, aioli or harissa to put on your favorite savory dishes, balsamic reduction to swirl over a plate before topping it with food or even mustard and mayonnaise for sandwiches. Refilling a used Plastic Wash bottle can be a somewhat confusing process if you have never done it before.
Plastic Wash bottle are designed to push a liquid substance through a small hole. This enables you to have greater control over where the substance in the bottle is applied, and how much is Plastic Washd out at one time. There are many different crafts projects where Plastic Wash bottles can be utilized.
Tie Dye Shirts
Fabric dye can be poured into different Plastic Wash bottles with Polyester Swabs, then Plastic Washd onto T-shirts to create a tie dyed look. To make a swirled tie dye, twist a wet T-shirt into a spiral, then Plastic Wash three different colors of fabric paint onto the shirt in a pie formation. After five minutes, lay out the shirt in the sun to dry. Wash before wearing.
Paint Containers
Children enjoy painting with washable tempera paints. However, children often need help squeezing the tempera paints out of their containers because the containers are not designed for small hands. One solution is to pour tempera paints into many different Plastic Wash bottles, which can be Plastic Washd easily by little children.
Cake Decorating
If you enjoy making cakes from scratch, you can fill different Plastic Wash bottles with different colors of frosting. Once the cake has been frosted with the base coat, you can use the Plastic Wash bottles to squirt frosting over the surface of the cake in different designs and patterns.

Plastic Dropper Bottles Using Ways

admin — Wed, 11 Jan 2012 02:05:45 +0000

Plastic Dropper Bottles are used in many fields, from cosmetics to medicine. The bottle is usually small and constructed of glass or plastic. The screw-on top contains a suction tube for dispensing liquids in small amounts or one drop at a time. Some tubes, especially those used for medicinal products, have measurements marked on them to aid you in releasing the correct amount.
1 Hold the Dropper Bottles in a vertical position, and check to see if the Dropper Bottles starts out empty. If the Dropper Bottles was packaged separately, you may need to gently rinse it out a bit before use. If it was in the medication, be sure to squeeze any excess out of the dropper and into the bottle of medicine.
2 Gently squeeze the rubber end of the dropper Plastic Sample Bottles, using your thumb and forefinger. This will squeeze excess air out of the Dropper Bottles and prepare the dropper to suck up the medicine.
3 Place the Dropper Bottles into the bottle. Stop squeezing the rubber end, but continue to fold onto the dropper. Lift the dropper up enough to see how much medicine is in your Dropper Bottles.
4 Gently squeeze the rubber end until the medicine is leveled with the measurement you need.
5 Let go of the rubber end. This will cause an air bubble to pop up and look like the medicine is off measurement, but you have the correct amount in the dropper.

Reagent Bottle,one kind of Pipette,are widely used all over world.we use them every day,so what we should notes when we using the Reagent Bottle?
Notes Of Reagent Bottle
Filling
When filling bottles always allow a 10% dead-space for expansion and safe pouring of contents1. Use a funnel appropriate to the solution entering the bottle. Protective clothing comprising a long sleeved laboratory coat or gown, rubber gloves and safety goggles should be worn as a minimum standard for handling any laboratory reagent. If there are hazardous vapours associated with the solution a fume hood should be used and a face mask worn.
Labelling
The label on the bottle must accurately describe the contents and should carry the date when the bottle was filled and by whom. Labels should be protected from the contents of bottles by coating with a thin layer of paraffin wax or spraying with Teflon.
Carrying
Large bottles should only be carried in specially designed holders. Low density polyethylene carriers with cover locks are recommended for safely carrying acids119 120 as any spilled contents are contained within the carrier. Never hold or carry a bottle by its neck,Test Tube.
Pouring
Hold the bottle with both hands when pouring and wear rubber gloves to protect the hands from spillage’s or drips. Pour the contents slowly to prevent spurting. After pouring flush the outside of the bottle with water before returning it to storage.
When bottles are opened many compounds such as those containing hydrogen chloride, bromine, ammonia and peroxides release toxic gases under pressure. A face mask, together with appropriate protective clothing, should be worn and the bottle opened carefully in a fume hood.

Brief Introduction Of Reagent Bottle And Wash Bottle

admin — Tue, 20 Dec 2011 03:48:21 +0000

Reagent Bottle, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers and are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves. Some reagent bottles are tinted amber (actinic), brown or red in order to protect light-sensitive chemical compounds from visible light, ultraviolet and infrared radiation which may alter or break them down. The bottles are called “graduated” when they have marks on the sides indicating the approximate (rarely exact) amount of liquid at a given level within the container. A reagent bottle is a type of laboratory glassware. The term “reagent” refers to a substance that is part of a chemical reaction (or an ingredient of which), and “media” is the plural form of “medium” which refers to the liquid or gas which a reaction happens within, or is a processing chemical tool such as (for example) a flux.
A Wash Bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks.
Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.
Most wash bottles are made up of polyethylene, which is a flexible solvent-resistant petroleum-based plastic. Most bottles contain an internal dip tube allowing upright use.
Wash bottles may be filled with a range of common laboratory solvents and reagents, according to the work carried out in that lab. These include: deionized water, detergent solutions and rinse solvents such as acetone, isopropanol or ethanol. In biological labs it is common to keep sodium hypochlorite solution in a wash bottle to conveniently disinfect unneeded cultures.

Plain Tube And Test Tube Usage

admin — Mon, 12 Dec 2011 06:32:02 +0000

Test Tube are fairly close to being common in a laboratory environment. Typically about finger length, these mad scientist staples are found by the hundreds in settings including chemistry labs to hospitals to a kid’s chemistry set. Anyplace where it’s important to always keep biological samples separate, you’re likely to find them.
Test tubes are also referred to as beakers, sample and culture tubes, however some people maintain that there is a difference in the shape of the mouth. They typically have a circular lip on them which makes them easier to pour, and this might not be present in culture tubes, however the terms are typically interchangeable.
How to Use Plain Tube
1 Use tongs to grab your test tubes at the center. Wrap the tongs around the center, and hold firmly but not too tightly.
2 Keep the test tube angled away from you at all times, in case of any splashing.
3 When warming the test tube, hold it over the flame at an angle, moving it back and forth gently.
4 Never smell anything inside a test tube directly or look inside a test tube. Waft the air or fumes emitted from the test tube away from you.
5 When not using a test tube, place it upright in the test tube holder. This will help prevent spillage or accidents.
Test tubes are a key part of many science projects. They allow you to hold potentially hazardous and irritating chemicals at a safe distance. Furthermore, they’re also resistant to high temperatures, allowing you to heat chemicals inside them without spilling or coming into contact with the chemicals. Test tubes’ long, deep bodies allow you to keep away from most of the fumes chemicals can emit as well. Using test tubes requires care; because they are made of glass, they can break and hurt users.

How To Read A Serological Pipettes

admin — Mon, 28 Nov 2011 04:51:38 +0000

Serological Pipettes come in various sizes and are of various functionalities. They are light weight and simple, complex and even electronic. Some sort of vacuum is created above the surface of the liquid and that’s how the liquid is hold and whenever the vacuum is slowly filled with air consequently the liquid travels through the route to the mouth. The modern ones are highly accurate and precise in their calculations. The multi channel ones can be rotated 360 degree and hence they are easily to manipulate. Even they can take lot of samples at a time. In order to remove the mouth pipetting some sort of fillers are available and hence that makes the liquid sucking more convenient. There are cases that the tubes from which the liquid is supposed to be taken are really deep, in that case it is very much important to make that the end part does touch the surface of liquid and hence here the length of the tip is also a matter to be considered. The suction is mainly provided by the plunger. The volumetric ones are used for the titration purposes and hence need to be very accurate.
First thing is to examine the Serological Pipettes closely and you should note the calibrated volume of the Serological Pipette in the millimeter units. This number is etched clearly near the top. You can find that the evenly spaced numbers and marks along the length of the Serological Pipette are the calibration marks which correspond to the precise volumes. Moreover, the volume marks which correspond to the liquid level is the liquid volume that delivered when the Serological Pipette is completely drained by the gravity.
The second thing is to draw the water unto the Serological Pipette by using the suction of Serological Pipette bulb, or by mouth, to any level in the top half of calibration range. You need to stabilize the water level before you are going to proceed. It can be done with the bulb, or by tightly stopping-up the top of the Serological Pipette with a thumb or finger.
The third thing is to raise the Serological Pipettes to the eye level and you should note the curved surface which forms the top of the liquid column. After that, you can directly place the meniscus in front of your best-trained eye and make note about the calibration numbers which the meniscus falls between. The numbers can represent the fractions of the calibrated volume.
The next thing is to make note about the liquid volume. And finally, you can estimate the fractional subdivision.

Wash Bottle

A Wash Bottle is a plastic squeeze bottle that hold a liquid, such as water, soap, or solvents such as acetone, methanol, hexanes, etc. They are used to rinse out and gently spray water or solvent into something.It is used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks.
Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.
Wash Chemical Bottless may be filled with a range of common laboratory solvents and reagents, according to the work carried out in that lab. These include: deionized water, detergent solutions and rinse solvents such as acetone, isopropanol or ethanol. In biological labs it is common to keep sodium hypochlorite solution in a wash bottle to conveniently disinfect unneeded cultures.
As is always the case when transferring reagents between containers, for safety always ensure the label on the Plastic Wash Bottles matches the contents of the bottle, and do not mix reagents or return them to the original container. Additionally, wash bottles are not appropriate for long term storage and must never be used for dangerous reagents. Volatile liquids such as acetone or methanol require a bleed hole to reduce dribbling – often a vent is integrated into the top of the internal straw.

Plastic Pipette Tip Assembly

admin — Mon, 29 Aug 2011 01:28:43 +0000

Plastic Pipettes tip is a very important part of pipette.
At the tip (pipette tips) put pipette, many people turned their guns on the box hard knock in a few, then wrong, as this would result in the internal pipette accessories (such as spring) due to instantaneous impact force generated percussion have become loose, and even lead to scale adjustment knob stuck. Correct method is to pipette (control) into the tip in the vertical, rotating slightly around a little hard to make it closely. If multi-channel (such as 8 or 12) pipette, the pipette can be the first at the first tip, and then obliquely inserted, after the forward direction of shaking can be locked in place. Tip card is a little more than a sign of tight O-ring, and you can see part of the formation of clear ring connection.
Pipette method
1) Pre-washing tips:
We installed a new tip or increase the capacity value of the future, should the need to transfer the liquid draw, emissions two to three times, doing so is to enable the tip to form a homogeneous liquid film wall to ensure the accuracy of pipetting work and accuracy, the entire pipette with high reproducibility. Second, learning from high-volatile organic solvents or liquid, volatile gases will form a negative pressure room in the white sleeve, resulting in leakage of the case, then we need four to six pre-washed, so the white interior of the sleeve gas saturation, negative pressure will automatically disappear.Plastic Petri Dishes
2) aspiration:
First pipette according to the first stop button discharge point, and then immersed in liquid suction head vertically, the depth of immersion is: P2, P10 less than or equal to 1 mm, P20, P100, P200 less than or equal to 2 mm, P1000 is less than or equal to 3 mm, P5ML, P10ML less than or equal to 4 mm (immersed in too deep, then the hydraulic fluid will absorb a certain precision, of course, the specific liquid immersion depth should be based on the container in full bloom size flexibility), a smooth release the button, remember not too fast.
Before pipetting, to ensure that pipette tip and the liquid at the same temperature. Absorb the liquid, the pipette to keep upright state,
Then you can take two pipette method.Glass Petri Dishes
First, the forward pipetting method. Press the button with the thumb to the first stopping point, then slowly release the button back to the origin. Then press the button to drain fluid first stopping point, pause for a moment to press the button to the second stop point blow residual liquid. Finally, release the button.
Second, reverse pipetting method. This method is generally used to transfer high viscosity liquid, bio-active liquid, foaming liquid or very small amount of liquid, its principle is to first set the range of inhalation than liquid, do not blow the transfer of liquid when the residual liquid. First press the button to the second stopping point, slowly release the button to the origin. Then press the button to set the first stopping point range of liquid discharge, continue to hold the buttons in the first stopping point (Do Do not press down), remove residual liquid tip, abandoned.
3) put the solution:
Subretinal fluid, the tip close to the container wall, the first button press to discharge the first stopping point, after a brief pause, and then to the second stop point, which could ensure that no residual fluid within the tip. If this operation there is still residual liquid, then you should consider replacing the suction head.
4) Remove the suction head:
Remove the tip and the new tip must not mix, so as to avoid cross-contamination.Lab Bottles
