Thermotubes Block Heater
Product Code : LSK-BL-10140
Thermotubes Block Heater (SKU LSK-BL-10140) is a dry block heater that replaces a traditional water bath for small-scale work: it holds six 16 mm diameter test tubes and warms or cools them to any set point between 15 °C and 65 °C, with no water involved. A digital display shows both the set point and the actual temperature, and it runs at low voltage from a 12 V AC/DC adapter. Science Lab Supplies provides this biology lab equipment in India and abroad from Ambala, quoting for schools, colleges, tender contractors and distributors.
Specifications
Each specification of the six-tube dry block is given its own row. In short, the waterless block accepts six 16 mm tubes, controls them between 15 °C and 65 °C with a digital set-point and actual-temperature display, measures 175 x 110 x 105 mm and is powered at low voltage through a 12 V AC/DC adapter.

Applications and Experiments for the Thermotubes Block Heater
Any practical that needs a few tubes held at a steady temperature can use the block instead of a water bath: enzyme reactions, temperature-effect studies and incubation of small samples. Because it holds just six tubes, it suits group work in school biology, B.Sc. biochemistry and microbiology teaching labs.
- Class 11–12 biology: effect of temperature on enzyme activity, running tubes at several set points between 15 °C and 65 °C.
- Respiration studies: holding germinating seeds at a fixed temperature for the Cellular Respiration kit, which examines the effect of temperature on respiration rate.
- Biochemistry practicals: timed catalase assays with the Principles of Enzyme Catalysis kit.
- Small-sample incubation where a full water bath would be wasteful or impractical.
Use only 16 mm test tubes so they sit properly in the block, and allow the actual temperature on the display to reach the set point before starting timed work.
Standard Scope of Supply
Each unit comprises the six-tube Thermotubes dry block with its digital display and the 12 V AC/DC power adapter. Test tubes, enzyme kits and reagents are not included; they can be priced as separate lines on the same quotation, as can an incubator for larger batches.
Packing, MOQ and Lead Time
Ask for one block or for a set for every bench group, and Science Lab Supplies will return a quotation that lists packing, delivery time and price for that quantity. Test tubes and enzyme kits can be added so the full practical is priced together.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
What temperature range does the Thermotubes Block Heater cover?
It warms or cools six test tubes to a set point between 15 °C and 65 °C, and its digital display shows both the set point and the actual temperature of the block.
Which test tubes fit the block?
The block accepts 16 mm diameter test tubes, six at a time. The 16 x 150 mm glass Test Piece is one tube in that diameter that can be quoted with it.
Does it need water like a water bath?
No. It is a waterless dry block heater intended as a small-scale substitute for a traditional water bath, running from a 12 V AC/DC adapter at low voltage.
Who supplies the Thermotubes block?
Science Lab Supplies prepares quotations for it and ships it from Ambala, India, either alone or with enzyme kits, test tubes and other biology lab equipment for schools, colleges and distributors.
