Urease Powder (Test Of Urea Urine)
Urease Powder (Test Of Urea Urine) (Product Code: SCL447/0132) is a powdered urease enzyme used to detect urea in urine samples in biology practicals. Students add it with an indicator such as phenol red, because urease breaks urea into ammonia and carbon dioxide and the rising alkalinity shows as a colour change; the pack is listed at 125 ml, analytical reagent grade, with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as the core of an enzyme activity kit for biology classes.

What Is Urease Powder Used For?
A typical school or college set-up uses three tubes: urine with a few drops of phenol red, water with indicator as a blank, and urine with indicator plus urease that has been boiled first. When a pinch of active urease is added to the first tube, the colour moves from yellow-orange towards pink-red as ammonia forms, while the blank and the boiled-enzyme tube stay unchanged. In one short practical, students see a positive test for urea, the specificity of an enzyme for its substrate and the effect of heat denaturation.
Because the test depends on enzyme activity, keep the container tightly closed in a cool, dry place and try the powder on a prepared urea solution before the class, so a weak batch or damp powder is noticed in advance. Warm rather than hot conditions speed the reaction, while boiling destroys it. Combined with phenol red and urea, this powder forms a low-cost enzyme experiment kit for school biology.

Related Biology Lab Products
Everything else a urease test for urea usually needs:
- Phenol Red (Test Of Urea In Urine) — the indicator that turns pink-red as urease releases ammonia.
- Urea (Urea) — for a known positive control and for checking enzyme activity before class.
- Sodium Hypobromide — a chemical method for urea, useful for comparing results by two routes.
- Test Tubes (With Rim) — for running test, blank and boiled-enzyme tubes side by side.
- Thermometer (Digital) — for extension work on how temperature affects enzyme activity.

Frequently Asked Questions
Why is Urease Powder (Test Of Urea Urine) listed with a capacity of 125 ml?
The listing gives the pack capacity of Urease Powder (Test Of Urea Urine) as 125 ml, which most likely describes the container rather than the weight of powder inside. Ask us through the contact page for the exact fill quantity before you order.
Do I need phenol red as well as the urease powder?
Yes. Urease Powder (Test Of Urea Urine) produces no visible colour by itself; it releases ammonia from urea, and an indicator such as phenol red shows the resulting rise in pH. Order the indicator alongside the enzyme if your lab does not already stock one.
Why did the urease test tube not change colour?
When a test with Urease Powder (Test Of Urea Urine) shows no change, check that the enzyme was not heated or stored damp, that indicator was added, and that a prepared urea control turns colour. A failed control points to the enzyme or indicator rather than the sample.
What is the shelf life of Urease Powder (Test Of Urea Urine)?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is given for Urease Powder (Test Of Urea Urine). Ask us for the expiry date of the batch you are quoted, store it closed, cool and dry, and confirm enzyme activity with a urea control each term.
Who supplies Urease Powder (Test Of Urea Urine)?
Urease Powder (Test Of Urea Urine) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India. The company can quote the enzyme together with phenol red, urea and test tubes, so a complete urea-in-urine practical can be ordered from one source.
What should an institutional enquiry for this urease powder include?
An enquiry for Urease Powder (Test Of Urea Urine) should give product code SCL447/0132, the number of packs, any companion reagents, the delivery address and billing details. We quote for schools, colleges and distributors in India and international markets.
