Dropper Bottle & Chemical Bottles

Posted on February 7, 2012 by admin

Chemical Bottles
Plastic bottles used specifically for the storage and transport of chemical substances should be disposed of properly. These are usually used in a laboratory setting and may contain chemicals that are toxic and dangerous to humans as well as the environment. Properly disposing of chemical bottles will ensure both you and your surroundings are safe.
1 Check the label on the Chemical Bottles to determine if the chemical that was in the container is on the list of acutely hazardous wastes. Search the list thoroughly to see if the name of the chemical is on the list. If the bottle contained a chemical on the list, the bottle must be disposed of as chemical waste. If this is the case, place the bottle in the labeled chemical waste box or bin.
2 Rinse the chemical bottle three times with water or suitable solvent and let it air dry, if the chemical it contained is not on the hazardous list. After rinsing, place the bottle in a well ventilated area to air dry. If the bottle has visible residue that cannot be removed by rinsing, place the bottle in the receptacle for chemical waste.
3 Place the empty chemical bottle in the appropriate recyclable container or receptacle. Check the bottle to ensure it is properly cleaned and free of residue after it has dried. Carefully put the bottle in the recyclable container to dispose of it.
Dropper Bottle 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 Unscrew the cap from the dropper bottle. Press the rubber bulb between your fingers to dispense any liquid already in the tube. Screw the cap back on and shake the bottle if necessary for the type of liquid you are dispensing.
2 Unscrew the cap again and squeeze the bulb while the tube is inside the bottle. This will draw the liquid up into the dropper tube. You may need to tilt the bottle if the liquid level is low. If using a measured amount, manipulate the bulb to get the liquid to the measurement mark indicated for your use. To release liquid from the dropper, press the bulb while the tube is not within the liquid.
3 Press the bulb briefly to release drops. Do this for each drop indicated for your purposes.

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

Posted on December 20, 2011 by admin

Wash Bottle
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.
The article comes from Pipette.Sorfa reagent bottle and wash bottle are suitable for the hospital, the school, unit laboratories and so on Industrial and mining establishment, stores each kind of chemicals, the reagent solution to use. Recently uses for in the petroleum chemical industry to replace the specimen bottle, makes specimen depositing to use …

Plain Tube And Test Tube Usage

Posted on December 12, 2011 by admin

Plain Tube And Test Tube
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

Posted on November 28, 2011 by admin

Serological Pipettes
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

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.
