Labconco™ Tubes with Stems for RapidVap™ N2 Evaporation Systems

Borosilicate glass tubes for use with RapidVap N2 Evaporation Systems only. The ground glass tubes offer better fit and heat transfer for faster evaporation rates. The stems are designed for use with Cool-Zone timed end point determinations. To minimize evaporation time, the tube with the correct end point stem should be used. For example, if an end point of 1.5 ml is desired, selecting Tube 7913500 with a maximum 3.0 ml end point volume would result in an unnecessarily long period required to evaporate the final 1.5 milliliters in the stem. Flat-bottom tubes are for use in applications when samples are taken to dryness. Each graduated 600 ml tube has a sample capacity of up to 450 ml when vortexing. Each graduated 170 ml tube has a sample capacity of up to 125 ml when vortexing.
