Sample Bottle is a kind of Reagent Bottle.Sample Bottles is also called cleaning bottles, sterile bottles, clean bottles, filter bottles,It always made by glass,plastic,It used to carry solid grain or liquid,It can be divide into two types:
The first one is wild-mouth Sample Bottles,They have a wild mouth ,it usually carry small particles of solid, powder,wild mouth make it esay to put the solid particles to enter them.
The other is narrow-mouth Sample Bottles,They have a narrow mouth ,it usually carry liquid,the narrow mouth make it uneasy to pour out.
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 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.
As is always the case when transferring reagents between containers, for safety always ensure the label on the wash bottle 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.
