Drop volume averages 40 µl per drop, depending on reagent used. Both natural and white dropper bottles have excellent chemical resistance and have been rated suitable for most biotech, diagnostic, and pharmaceutical applications. Natural, clear dispensing bottles permit easy content identification, while white dispensing bottles protect UV light-sensitive products. Closures are polypropylene and are available in white or assorted colors (five each of white, red, yellow, green, blue) for easy reagent identification.

Dropper bottles provide accurate, repeatable dispensing of various reagents and offer an alternative to pipetting.
