Potassium Metal
 (1).png)
Product Code : SCL-LC-12272
Potassium Metal (SKU SCL-LC-12272) is elemental potassium, K, a highly reactive alkali metal used by trained staff for controlled demonstrations of Group 1 behaviour and for reagent work under a written SOP. Because it is water-reactive and pyrophoric, it suits only college and institutional laboratories with hazardous-chemical controls. Science Lab Supplies, working from Ambala, India, accepts enquiries for it from such laboratories, tender contractors and distributors.

Applications and Experiments for Potassium Metal
Potassium can be used in a controlled demonstration by trained staff to illustrate Group 1 reactivity trends alongside sodium. It also supports lessons on oxidation, reducing behaviour and metallic bonding, and on the storage, segregation and SDS interpretation of water-reactive chemicals.
- Class 11 chemistry: the s-block elements, comparing potassium with sodium down Group 1.
- B.Sc. inorganic chemistry: alkali-metal reactivity, metallic bonding and reducing behaviour.
- Reagent use by trained staff under a written SOP.
- Safety training on pyrophoric and water-reactive substances.
Standard Scope of Supply
The supply is one container of potassium metal per unit, held under a protective medium or sealed containment, with a batch label, hazard marking, the Safety Data Sheet and the dangerous-goods transport documents. Purity and quantity follow your quotation. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Request a quotation for a single container or for several institutional labs; it will give packing, delivery time and price for that quantity and confirm the dangerous-goods packing for this metal. Other reagents and chemistry lab equipment in India can be quoted alongside.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
Why is potassium metal so hazardous?
It is water-reactive, pyrophoric and a strong reducing material, so contact with water, damp surfaces or humid air must be prevented. That is why it needs strict dry storage, restricted access and handling only by trained personnel.
What protective medium is the potassium supplied in?
It comes under a protective medium or in sealed containment. The exact medium is stated on the label of your batch, and you can ask us to confirm it before ordering.
Who supplies the Potassium Metal?
Science Lab Supplies, a laboratory chemicals supplier in India with its base in Ambala, quotes this metal for trained college and institutional labs and distributors, stating purity, storage medium and pack size each time.
What safety controls does potassium metal need?
A written SOP, trained supervision, emergency controls such as an Eye Wash Station, and the current Safety Data Sheet. Wear Safety Glasses and dry Gloves - Protective, store it dry away from water, acids and oxidisers, and never issue it to students unsupervised.
