What Is the Water Bath Test Tube Rack Used For?
Tubes left loose in a water bath tip over, float or cluster near the heater. A rack keeps each tube upright in its own position, so every sample gets the same water contact and can be labelled by position for timed experiments such as enzyme activity, food tests or serology incubations. Stainless steel is a good choice for a rack that spends hours in warm water, because it does not absorb water and is easy to wipe clean.
The 32 mm holes accept many common test tubes, boiling tubes and small bottles; check the outside diameter of your vessels first. Several racks can be loaded at the bench and then placed in the bath together, which speeds up class practicals. Match the number of racks to your bath size using the table above, and remove racks when the bath is drained so the tank can be cleaned. It is a simple, durable addition to lab water bath equipment in India.
What to Specify When Ordering
