Borosilicate glassware

The best replacement for borosilicate glassware is stainless steel. Stainless steel takes the heat, won t break, and, most importantly, is about as resistant to chemical degradation as the chemist can hope to find. For those items that won t be subjected to direct heat there can be some steel/metal or steel/plastic hybrids. In figure 3 is shown how flasks of any size can be made with two stainless steel mixing bowls welded together. Also shown is the vacuum adaptor and condenser. For the condenser only the inner pipe need be steel. The outside pipe can be copper or something. As for the other components of a distillation set up, well, they are made just as they look. 

Boron is obviously a component of borosilicate glassware, which should therefore be avoided. Apparatus should therefore be made of PTFE, soda... 

Glassware. All special borosilicate glassware was fabricated in-house. Kudema-Danish (K-D) evaporators and the modified Snyder columns were constructed as per the design described previously (25) adsorption glass... 

Avoid borosilicate glassware during sample preparation. Use plastic bottles, pipettes, and flasks. 

Because the thick glass (of a heat exchanger) that had been annealed several times is now confronting hot water, it is more likely to fail (corrode and break) than other borosilicate glassware. 

How might using borosilicate glassware contribute to lab safety ... 

Effect of Temperature. Expansion does not have much effect on the borosilicate glassware, but it does on the water contained. So, in calibrating glassware with water by weight, correction should be made for temperature. ... 

Triethylamine trihydrofluoride4 is an oily liquid that does not attack borosilicate glassware. The checkers purchased it from Aldrich Chemical Company, Inc., but it is also available from Fluka Chemical Corp. and other suppliers.
