1000ml Chemistry Lab Distillation Apparatus,Vigreux Column,Vacuum Kit,24/40

This kit is flexible and the glass is high quality. I have distilled 12 liters through mine so far and everything still operates well. The included tubing is of good quality and the keck clamps last and hold after several uses and washings. I put the system under a 10 micron vacuum (pretty deep vacuum, buries my analog gauge) for long periods of time and have no worries about it holding up. Everything was well packaged and arrived much sooner than quoted.

Liebig condenser is not really appropriate for vacuum distill due to inherent inefficiency; but good value, glass is on thicker side, came extremely well packaged for shipment. Start here and add better condenser later. No regrets.

Nice thick glass but lots of nicks and small cracks at the glazed parts of the joints. The entire system is still very much usable. Items were nicely packed and secure. I can get a much better quality kit locally (with much faster shipping) for about the same price.

Very good quality glass. I am very impressed with this product. I have purchased from Ding before and will again in the future. They are fair and take care of problems if they occur.

It came on time and very well packed, nothing is broken and I liked the quality

Has good value and a good thickness for the price. 30 dollars is extremely cheap for heavy walled flasks, adapters, 2 thermometers, 200mm vigreux column and 200mm condenser. Slight scratches on some glass and some had a crack. Customer service is incredible and sent replacement glass and some extra k-clips right away. 10/10 will shop again. Glass did smell very much of chemicals, but that went away after a simple wash. Distilled EtOH, Napathalene, toluene, and dichloromethane effortlessly, glass handles heat well.

Good value. Very fast shipping.

Great product!!!
