Dropping Bottles

Dropping bottles, an alternative to pipetting devices, allow for the repeated, consistent, accurate dispensing of reagents one drop at a time or in a stream. The dropper control tip on dropping bottles snaps securely into place, providing a leak-proof seal. Polyethylene dropping bottles feature ideal chemical resistance and are suitable for dispensing most acids, bases and alcohols. Glass dropping bottles are chemically and biologically inert. Amber glass droppers provide protection against UV rays, making them suitable for use with light sensitive materials.
