Customer Reviews

Based on 3 reviews
good glassware

This is good quality glass. Just note that it uses a angular interface bulge ground glass joint, not the arc bulge joint that most other companies use, and needs a different keck clamp.

Lucia Calero
Good for someone who does essential oil regularly.

So many parts you have to buy .

Very nice flow control two-way adapter

This is a great flow control adapter for vacuum applications. The two-way direction and controllable addition make it really useful in the chemistry labs. It has good quality as well, making it safe for use under vacuum or ambient environment.
