Distillation - Wikipedia

A simple set-up to distill dry and oxygen-free toluene. Diagram of an industrial-scale vacuum distillation column as commonly used in oil refineries: A rotary evaporator is able to distill solvents more quickly at lower temperatures through the use of a vacuum. Distillation using semi-microscale apparatus.

The mixture was then vigorously stirred in a closed round-bottomed flask at reflux for 10 h and the product (PEGX-COOH) was isolated by a rotary evaporator. At last, PEG was grafted on SiO 2 surface by interaction between SiO 2 -APTES and PEG-COOH ( Fig. 1 d). 0.13 g of SiO 2 -APTES was dispersed in 24 mL of toluene in a round-bottomed flask ...

The Rotary positive displacement gas meters are designed to measure gas volumes with a high degree of accuracy. The measuring chamber is machined out of solid metal so the displaced volume is fixed by the dimensions of the impellers and measuring body. Since the displaced volume is fixed, the accuracy of the meter remains constant over time.
