I just wanted to say thank you for the prompt delivery of my total order, I just ordered from labtastic the same equipment like a month before Stony labs, and labtastic has still not shown up. So thank you very much I like everything about my equipment and I will definitely be buying more equipment from Stony labs Rudy Romero

Bought this reactor and it has worked as intended while the price was VERY accessible. I am happy with my purchase. I might buy a second one. It would be great if you had an option with 24/40 ports that are all straight.

Good quality

Perfect for my needs, arrived quickly and safely. Excellent packaging

The only modification I made to the Lab Jack, I added non slip rubber pad (Amazon). This supports my aluminum bar for the drill press.

Had a little hold up in postal service... Customer service exhalent, resolved issues! Pump is best for my vacuum oven. Works fast and easy to setup, using a high iso number oil for deep vacuum... Lovely job!

I am using this in a warm water bath for materials in a laboratory. Many of these come in 4ml or 15ml vials, so I would have much preferred a smaller footprint if possible to keep the vials from tipping over in the water.
Otherwise, great sturdy product and I would buy again.
