'Closing down' the Schlenk Line. Step 1: Ensure that all Schlenk flasks connected to the line are under inert gas and that all taps and stopcocks are closed. Step 2: Open the vent valve by twisting anti-clockwise and then immediately turn off the vacuum pump. You will hear a whistling noise as the vacuum manifold is re-pressurised with air.

necked, round-bottom flasks allows for simultaneous connection to the Schlenk line, temperature monitoring, and a port for hot-injection of precursors, where appropriate. While we typically use the 50-mL flasks listed, 100-mL three-neck round-bottom flasks with 24/40 joints are an effective alternative, particularly for larger-scale reactions. • Liebig condenser (e.g. ChemGlass, cat. no. Two-stage rotary vane pumps are characterised by their high water vapour tolerance and reliability. Due to their design they withstand large amounts of water vapour in the vacuum pump's inlet vapour stream. This 'water vapour tolerance' is the maximum inlet pressure point at which the pump is able to operate with pure water/fluids and at the same time prevents them of condensing inside the pump

Labs have a variety of separation, processing, and analytical techniques happening all the time. Vacuum pumps aren't the first thing that come to mind, yet vacuum is an integral part of so many techniques. Enter VWR and Welch. Enabling science through applied. The Schlenk line (also called a vacuum gas manifold) was introduced to provide an inert atmosphere to reaction vessels, which is useful for safely and successfully manipulating air-sensitive. We report that a Schlenk line, stir plate, and sample box change airflow patterns, as observed in computational fluid dynamics (CFD) simulations, and show using colored smoke that the airflow is significantly impacted not only by the sash position but also by the height of the reaction. Materials and methods. The fume hood smoke plume experiments were designed to provide readily discernable.
