Geiger Muller Tube
Product Code : LSK-PL-10283
Geiger Muller Tube (SKU LSK-PL-10283) is a multipurpose GM tube, sensitive to alpha, beta and gamma radiation, for detecting ionising radiation in physics teaching. Connected to a suitable counter or scaler, it is used for radioactivity experiments in senior secondary schools and B.Sc. nuclear physics practicals. Science Lab Supplies supplies the tube from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The tube sits in a housing with a protective cover and a 10 mm diameter support rod, and has an integral lead ending in a BNC plug. It has no built-in anode resistor, so it must be used with a counter that has one. The recommended bias voltage is 500 V.

Applications and Experiments for the Geiger Muller Tube
Paired with a scaler or ratemeter, the tube counts the radiation reaching its window, so students can measure background count, compare sources and study absorption. It is used for radioactivity work in senior secondary physics, in B.Sc. nuclear physics practicals and in teacher-training laboratories.
- Measuring background radiation.
- B.Sc. practical: characteristic (plateau) curve of a GM counter.
- Absorption of beta particles by aluminium sheets.
- Inverse-square law for gamma radiation.
Safety: the tube runs at a high bias voltage (500 V recommended) and is used with radioactive sources. Run experiments only under a trained teacher's supervision and follow the institution's rules for storing and handling sources.
Standard Scope of Supply
The Geiger Muller Tube is supplied as a single mounted unit: the GM tube in its housing with protective cover, the 10 mm support rod, and an integral lead with BNC plug. A counter with a built-in anode resistor and radioactive sources are not included.
Packing, MOQ and Lead Time
Quotations can be issued for a single tube or a set for several counting stations, and each states the packing, delivery time and price for that quantity. A scaler timer or ratemeter can be quoted alongside so the counting setup arrives as one order.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code, so it can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Put questions through the contact page, add the tube to the enquiry cart, or check the lab tender page for tenders.
Frequently Asked Questions
Does this GM tube work with any counter?
No. It has no built-in anode resistor, so it needs a counter or scaler that provides one. It connects through its integral lead and BNC plug, with a recommended bias of 500 V.
Which types of radiation does it detect?
It is a multipurpose tube sensitive to alpha, beta and gamma radiation. The window is 9.14 mm in diameter, and the housing includes a protective cover.
Who supplies the Geiger Muller Tube?
Science Lab Supplies supplies it from Ambala, India, as a physics instruments supplier in India, and quotes the tube together with any counters or related items your laboratory lists.
Is it safe for school use?
It works at a high bias voltage and is always used with radioactive sources, so experiments should be run only under a trained teacher's supervision and within the institution's radiation safety rules.
Related Radioactivity Equipment
A GM tube only detects radiation; counting and displaying it needs a scaler or ratemeter, and students often model decay before handling real sources. These four items build a radioactivity and modern physics bench around the tube and can be quoted together.
