Bottle Beakers are excellent for use with biological and pathological specimens, but can also be used for storing industrial laboratory chemicals and reagents. They are designed with a slight shoulder for easy pouring and handling. Graduated in ml and ounces. Mix, measure, and store in the same container.

 

Attached black thermoset (phenolic) caps with Polyseal cone liners form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off.
