This 2.4L PYREX desiccator has a rugged 24/29 standard taper stopcock with tooled hose connection
that serves 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 desiccator. This design eliminates
the need for grease. The tubulation O.D. is approximately 10 mm. Approximate bowl volume capacity
is 2400 mL. For replacement bowl, see Cat. No. 3081-150LO; for cover, see Cat. No. 3121-150CO;
for replacement stopcock, see Cat. No. 3121-STPK.
Warning: Do not heat or subject to pressure. Rated 1-atmosphere vacuum. |
