Product Code : SCL-CL-11450
Apparatus for Water Synthesis (Eudiometer) (SKU SCL-CL-11450) is a graduated glass tube, sealed at one end, in which a measured mixture of hydrogen and oxygen is sparked so that the gases combine to form water. Measuring the gas volume before and after shows the volume ratio in which they react. From Ambala, India, Science Lab Supplies provides the tube to school and college chemistry departments, training institutes, resellers and lab tender contractors.
Specifications
All specifications of the 16 mm eudiometer tube are tabulated below. In short, it is a resistant glass tube with fine 0.1 mm graduations; one end is closed and carries an electrical conductor filament, so a spark can be passed through the gas inside, while the open end is used for filling with gas over liquid.

Applications and Experiments for the Eudiometer
The eudiometer is used to show that hydrogen and oxygen combine in a fixed ratio by volume, two volumes of hydrogen to one of oxygen, when sparked to form water. It suits senior-school chemistry on gas laws and stoichiometry and introductory gas-analysis work in college chemistry.
- Class 11 chemistry: Gay-Lussac's law of gaseous volumes and the composition of water by volume.
- B.Sc. chemistry: basic volumetric gas analysis, with hydrogen prepared in the Simple Kipps Appliances generator.
- Teacher demonstrations: pairing water synthesis with electrolysis of water, for example with the stainless-steel Electrolysis Kit, to show both directions of the reaction.
A hydrogen-oxygen mixture explodes when sparked. The demonstration should be run only by a trained teacher, with small gas volumes, Protective Glass eyewear and students at a safe distance.
Standard Scope of Supply
The eudiometer is supplied as a single graduated glass tube with its sealed-in conductor filament, as described above. The spark source, gas supply and trough are not included, and any of them can be requested as additional lines on the quotation prepared for your laboratory.
Packing, MOQ and Lead Time
A quotation can be prepared for a single tube or for a chemistry lab equipment order covering several classrooms. It gives the packing, the delivery time and the price for that quantity, and gas-preparation glassware can be quoted alongside the eudiometer on the same document.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. Ask for eudiometer prices by writing in from the contact page or by saving the tube to the enquiry cart; procurement officers can follow the lab tender page.
Frequently Asked Questions
What is a eudiometer used for?
It measures changes in gas volume during a reaction. In this set it is used to spark hydrogen with oxygen and show that they combine in a 2:1 volume ratio to form water.
Is a spark generator included?
No. The tube with its conductor filament is supplied on its own. Connect it to the spark source your laboratory already uses, or ask for one to be quoted with the tube.
Who supplies the Apparatus for Water Synthesis (Eudiometer)?
Science Lab Supplies, working from Ambala in India, is the supplier. It quotes single tubes for schools, colleges and training institutes and prepares larger quotations for distributors and tender contractors.
Is the experiment safe for students?
Sparking hydrogen with oxygen is explosive, so it should be a teacher demonstration using small volumes, with eye protection and students kept back from the tube.
