Hoffman Voltameter Stand

Product Code : LSK-CL-10245

Hoffman Voltameter Stand (SKU LSK-CL-10245) is a metal stand with a support clamp and a 600 mm rod, made to hold a Hoffman (Hofmann) voltameter upright during water electrolysis. Because the voltameter must stand vertically and steadily while gas collects in its limbs, a dedicated stand makes the demonstration safer and the volume readings easier to take. Science Lab Supplies arranges supply from Ambala, India to schools, colleges, contractors and distributors.

Specifications

The table gives the stand's details one per row. In short, the Hoffman voltameter stand is a metal stand supplied with a 600 mm rod and a support clamp that grips the glass voltameter, so the whole apparatus, reservoir bulb included, can be mounted upright with room below for the electrode connections.

Applications and Experiments for the Hoffman Voltameter Stand

The stand supports the voltameter in every practical the apparatus is used for: electrolysis of water, comparing the volumes of hydrogen and oxygen, and measuring gas volume against charge passed. Holding the glass firmly and vertically keeps the graduated limbs level for accurate readings.

• Class 10 science (NCERT): the electrolysis of water demonstration, with the voltameter connected to an AC/DC Laboratory Power Supply.
• Class 12 chemistry: Faraday's laws practicals using the voltameter fitted with Electrode Platinum.
• B.Sc. labs: electrochemical equivalent experiments with a secured voltameter, comparing results with an Electrode Rod Carbon Voltameter.

Stand the base on a level bench, fix the clamp around the voltameter before filling it with electrolyte, and keep leads clear of the base.

Standard Scope of Supply

The Hoffman Voltameter Stand is supplied as the metal stand with its support clamp and 600 mm rod. The voltameter itself, its electrodes and the power supply are not included; list them on the same enquiry if you need the complete water-electrolysis set-up.

Packing, MOQ and Lead Time

Stands can be quoted to match the number of voltameters in your lab, or as replacements for existing apparatus. Science Lab Supplies will quote packing, delivery time and price for whatever number you give, including combined orders of chemistry lab equipment in India.

Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. Stands and voltameters can be priced together after a message on the contact page or a list in the enquiry cart; tender buyers will find the steps on the lab tender page.

Frequently Asked Questions

Why does a Hoffman voltameter need its own stand?
The glass apparatus is tall and must stay vertical while gas collects and electrolyte sits in the reservoir. A stand with a 600 mm rod and support clamp holds it steadily at a workable height.

Is the voltameter included?
No. The item consists of the metal stand, the support clamp and the 600 mm rod. The voltameter with electrodes is a separate product and can be quoted on the same enquiry.

Who supplies the Hoffman Voltameter Stand?
As a school laboratory equipment supplier in India, Science Lab Supplies provides the stand from Ambala and can quote it with the voltameter and spare electrodes in one go.

Can a general retort stand be used instead?
A retort stand with a suitable clamp can hold the voltameter, but this stand is intended for it, with a 600 mm rod long enough for the full apparatus.
