Description

A rubber bellow with a cotton net is a laboratory tool that is commonly used for transferring small amounts of solid materials or powders. It consists of a flexible rubber bulb that is attached to a tube, and a cotton net is wrapped around the end of the tube. The rubber bulb can be compressed and released to create suction, which draws the solid material or powder through the cotton net and into the tube.

Rubber bellows with cotton nets are available in various sizes, and the size of the cotton net can be adjusted to suit the specific application. They are easy to use and can be sterilized for use in sterile environments.
