Test Tube Rack, Z Type
Test Tube Rack, Z Type (Product Code: SLE/LI/40) is a three-tier, Z-shaped steel stand used to hold test tubes and wider tubes upright on the bench during experiments in school and college laboratories. Its powder-coated steel sheet carries holes of three diameters — 28 mm, 20 mm and 13 mm — so tubes of different sizes share one rack. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as a test tube rack for school labs in India.

What Is a Z Type Test Tube Rack Used For?
The rack keeps tubes upright and apart while reagents are added, reactions are watched, or samples wait their turn for testing. With three hole sizes on one stand, a student group can park narrow tubes in the 13 mm holes and wider tubes in the 20 mm and 28 mm rows, which suits practicals such as salt analysis and precipitation reactions. It works equally well as biology lab equipment in schools, where food tests are run in rows of tubes.
Check the outside diameter of your tubes against the three hole sizes before ordering. The compact 200 mm length leaves room on busy benches for burners and reagent bottles. Rinse off spills promptly and dry the rack; the powder coating protects the steel, so do not leave acids standing on it.
What to Specify When Ordering
- The number of racks needed, for example one per student group
- That your tube diameters suit the 28 mm, 20 mm and 13 mm holes
- Whether you also need test tubes, a test tube brush or a tube holder
