Test Tube Holders
Test Tube Holders (Product Code: SCI-293/019) is a brown wooden rack with 12 holes used to keep test tubes upright on the bench in school laboratories. Its 12 positions let a group line up a series of tubes, such as dilutions or one test on several samples, without them tipping over, making it a handy test tube rack for school labs in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the 12-Hole Test Tube Holder Used For?
A rack keeps every tube in a known order, which matters when students compare results: a row of tubes testing different foods for starch, an indicator in solutions of different pH, or a dilution series of a coloured solution can stand side by side and be read at once. It also gives a safe place to set down a warm tube taken from a clip, so that tubes are never laid flat on the bench.
Label the tubes or the rack positions before starting so that samples cannot be mixed up. Wipe the wooden rack dry after spills rather than soaking it, and clean chemical splashes off promptly so the wood does not stain or swell. When drawing up school chemistry lab equipment lists, plan one rack per practical group.
What to Specify When Ordering
- The number of racks, for example one per practical group.
- The outer diameter of the test tubes you use, since the hole size is not listed.
- Any test tubes, clips or stoppers to be quoted with the racks.

Frequently Asked Questions
How many test tubes do the Test Tube Holders take?
The Test Tube Holders have 12 holes, so one rack keeps twelve test tubes upright at the same time, enough for a full comparison series or for several students' tubes at one bench.
What are the Test Tube Holders made of?
The Test Tube Holders are made of wood in a brown colour. Wood is light, gentle on glass and stays cool to the touch when a warm tube is placed in the rack.
Which test tube sizes fit the holes?
The hole diameter of the Test Tube Holders is not given in the listing. Tell us the outer diameter of your test tubes through the contact page, and we will confirm whether they fit before quoting.
Is this a hand-held holder or a rack?
Despite the name, the Test Tube Holders are a 12-hole bench rack for standing tubes upright. For gripping a single tube over a flame, the separate wooden Test Tube Clips are the matching hand-held holder.
Who manufactures the Test Tube Holders?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Test Tube Holders as the OEM at its own licensed factory at Saha, Ambala, Haryana, India, and supplies schools, colleges, dealers and importers directly.
How should the wooden rack be cared for?
Wipe the Test Tube Holders with a damp cloth after use, dry them straight away and clean off chemical splashes promptly. Avoid soaking the wooden rack in water, which can make the wood swell or warp.
