Description

Technical Field

[0001] The utility model belongs to the field of water bath heating racks, in particular to a water bath heating rack for a laboratory. Background Art

[0002] In chemical experiments, glass reaction containers such as test tubes usually need to be heated in a water bath. When heating glass containers such as test tubes in a water bath, in order to ensure that they are heated evenly, the test tubes need to be clamped with test tube clamps so that the test tubes enter the water bath without touching the bottom of the water bath. The test tube clamps are then held by hand or fixed on an iron stand. However, this way of fixing the test tubes has the problems of unstable placement, easy slipping into the water bath, and failure to remove them in time when they need to be quickly removed for cooling in some special chemical reactions.

[0003] Therefore, a laboratory water bath heating rack is proposed to solve the above drawbacks. Utility Model Content
