General description

The CD Vial (Center Draining) has a unique conical interior bottom that promotes draining of the contents into the center bottom of the vial, where virtually all of it can be extracted. Maximum extraction of the contents can be done utilizing either a micropipette or syringe.
The sturdy CD Vial with the patented design is ideal for many micro applications. The conical well, located in the exact center of the vial bottom, features a smooth transition from sidewall into the well, and the bottom thickness dimension is the same in each vial.
The vials are manufactured from Boroisilicate Type 1 glass to safeguard against a change in the pH of the contents.
