Stopcock not included. For replacement, please see Cat. No. 3121-STPK Bulk packed polystyrene pipets are ideal for large-scale sterile and nonsterile liquid handling applications. Unique color-coded magnifying stripe for easier meniscus viewing. Sterile and nonpyrogenic and DNase-/RNase-free Accuracy within ± 2% at full volume Calibrated to deliver (TD-EX 20ºC) their contents with blowout.

(This is the suggested replacement for 3120-200 and 3100-200)This 5.8L PYREX® desiccators has a rugged 24/29 Standard Taper stopcock with tooled hose connections that serve as the vacuum inlet. It is designed so that its manipulation is not affected by the vacuum. To introduce vacuum into the desiccator, loosen the stopcock to disengage the PTFE plug from contact with the glass. A half turn from this position closes the desicc…

This PYREX® 500 mL distilling apparatus is used for determining nitrogen in organic compounds. This assembly includes a Kjeldahl flask specifically developed for this process and a Graham condenser with 10mm O.D. tubulations. Both the digestion and distillation stages can be performed in this flask. The assembly shown is the distillation stage, where the amount of ammonia, and hence, nitrogen, is established. The inlet tube al…
