More About this Item

These desiccators have a rugged 24/29 standard taper stopcock with tooled hose connection that serves as the vacuum inlet. The desiccator is designed so 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. Accepts tubing with a 10 mm OD. Desiccators require desiccator plates, sold separately.

Warning: Do not heat or subject to pressure.

  • Q:

    So just to clarify the answer above, you can heat this desiccator to 150 degrees in an oven (uniformly) and then use the desiccator to pull a full vacuum without any problems? This would be amazing for me as I stay under 150 degrees F. Thanks.

      The desiccator's glass has been tested for temperature, however it has not been tested under temperature and full vacuum. We can only suggest testing the unit under your specific needs. Given borosilicate glass' softening point, I do not suspect it would be an issue under full vacuum at 150F degrees, but we cannot say for certain since it has not been tested.

  • Q:

    Will this desiccator withstand repeated heating cycles at 200 degrees f.

      As long as the heat cycles are seen uniformly, like if the desiccator is placed in an oven, continuous heat cycles to 200F should not be an issue.
