Applications and Experiments for the Case Holder
In wet practicals the stand holds tubes while solutions are added, keeps a series of tests in order for comparison, and gives hot tubes a safe place to cool. With 12 places, one rack can serve a full qualitative test sequence at a single student station.
- Class 6–10 science: comparing reactions of acids, bases and salts in a row of rimless 16 x 150 mm Test Piece tubes.
- Class 11–12 chemistry: keeping the tubes of a salt analysis or functional group test in sequence, with reagent added from a 60 ml Glass Bottle, with Dropper 60ml.
- B.Sc. chemistry and biology practicals: holding reagent, sample and control tubes side by side.
- Science kits and demonstration benches in school chemistry labs; after the practical, tubes can be scrubbed with an 8-inch nylon Test Tube Brush lab.

Frequently Asked Questions
How many test tubes does the Case Holder take?
It has 12 holes, so it holds up to 12 test tubes upright at one time. That is enough for a full row of reagent, sample and control tubes in one qualitative test sequence at a single student station.
What is the rack made of?
It is made of wood with a brown finish. Keep the rack away from open flames, let hot tubes cool before handling them further, and wipe up any spilled reagent promptly so the wood stays clean and dry.
Who supplies the Case Holder?
This rack is a supplied item. Quotations for it come from Science Lab Supplies in Ambala, India, and can go to schools, colleges, dealers or tender contractors along with the rest of a chemistry order.
Are test tubes included?
No. The rack is supplied empty. Test tubes, rubber stoppers with or without holes and a wooden test tube clamp can be quoted on the same enquiry, so each bench receives a complete set.
