Dropper/Wash Bottle Application
Controlled dispensation of liquids in small volumes requires specialist lab plasticware in the form of dropper and wash bottles. These bottles allow the researcher to accurately control how much reagent or buffer is added to their solution or culture, avoiding over-dilution or toxicity. Both bottle types are commonly made of LDPE (low-density polyethylene), with caps sometimes made of polypropylene.
Dropper/Dropping bottles allow the precise addition of high-value liquids, drop-by-drop, to sensitive mixtures or solutions. These bottles may include screw-on caps or attached push on caps, which may be colored for simple recognition of the bottle contents.
Wash bottles employ a squeezable plastic and leak-proof cap to allow controlled dispensation in the form of drops or a thin stream of liquid. Bottle caps may come color-coded to allow easy identification, therefore increasing safety and time efficiency. The bottles themselves are manufactured to contain solvents safely and can come in a variety of sizes to meet the researcher’s needs. They are ideal for distributing buffers and disinfectants where needed; their long stem nozzle prevents any accidental loss outside the target container.
