Removing condensation from a cooling jacket

Click For Summary

Discussion Overview

The discussion revolves around methods to remove condensation from a cooling jacket of a glass vessel that is no longer connected to a pump. Participants explore various approaches to eliminate the condensation without damaging the vessel or interfering with photography of reactions occurring inside.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests using a warm air stream, such as a hair dryer on low, to remove the condensation.
  • Another participant proposes running acetone through the jacket, arguing that it should not condense and could effectively clear the moisture.
  • A later reply confirms that using acetone along with evacuating the jacket with a vacuum is effective for this issue.
  • For a long-term solution, one participant recommends using nitrogen to purge the jacket, asserting that this would prevent moisture from being present.

Areas of Agreement / Disagreement

Participants present multiple competing views on how to address the condensation issue, with no consensus on a single best method. Various approaches are suggested, each with its own rationale.

Contextual Notes

Participants express concerns about potential damage to the glass vessel and plastic parts when considering different methods, indicating limitations in the proposed solutions.

I have a glass vessel with a cooling jacket which previously had cold water running through it. However now it is disconnected from the pump and the jacket is empty, and there is condensation in the jacket from the little water that was left in there.

How can I get rid of this condensation? Would a vacuum work? Is there a liquid I could put through the jacket that does not condense? I could put the vessel in an oven but I'm worried the plastic parts will melt and I don't want to risk the glass vessel cracking.

I need to take photos of the reactions happening in the vessel but I can't see them properly due to the condensation. I tried filling the jacket with water, but even though its transparent the surrounding water is interferring with the photography.

Anyone heard of anything like this before?

Warm air stream through jacket or round the outside . Hair dryer on low .

Will try thanks! Also (don't know why I didn't think of this) Acetone! I can run it through and it shouldn't condense!

Thanks again!
 
Acetone and evacuating with a vacuum works well. For anyone with this problem in future

For a permanent solution (for long-term downtime), you can get a nitrogen bottle, blow nitrogen through it, then cap it. No moisture will be in it at all.
