Wheaton Science Products innovative microscale kits provide many advantages over traditional macroscale glassware. The reduced quantity of chemicals required for experiments translates into less chemical waste disposal. Savings on waste disposal are realized by many universities, colleges and industrial laboratories. Exposure to toxic materials and their vapors have been virtually eliminated with the use of microscale glassware. Less solvent consumption affords better air quality and reduced risk of fire or explosion. Microscale users enjoy improved skills in chemistry with quicker setup times and shorter reaction times, allowing more time for experiments. The Wheaton Connection®, a threaded connector joining two glass pieces, eliminates the use of grease or joint clamps. The Wheaton Connection is available with white polypropylene or black phenolic caps. The Wheaton Connection allows the use of inexpensive Wheaton vials as single-use reaction flasks, greatly reducing cleaning requirements. The vials are also used for the storage of intermediate compounds or final reaction products.

The Wheaton Micro Kit, complete with grease-free Wheaton Connections, simplifies many organic techniques and is helpful in synthesis and the study of reaction mechanisms. Microscale techniques, which are consistent with current analytical techniques, have the following important attributes: safe, less exposure to toxic and radioactive materials and possible carcinogens; environmentally friendly, reduced disposal problems; economical, drastic reduction of consumption of expensive chemicals; no breakage from frozen joints. Components are assembled with grease-free, screw-threaded Wheaton Connections. Wheaton Connections that are made from phenolic have a working temperature of up to 180°C. All caps have open tops and Teflon® faced septa for maximum versatility. Flask sizes range from 1 mL to 10 mL. Graduated V Vials® with interior conical bottoms are included for reaction and collection vessels. The 1 mL V Vial is graduated at the 0.1 mL level. The compact design of Wheaton grease-free, microscale apparatus makes it possible to join components on a desktop. Viton® “O” rings are included in the kit for gas inlet tubes or thermometers. Because components hold themselves together, only minimal clamping is necessary.
