How Does It Compare with Other JLab Water Test Kits?
| Kit | Parameters | Reagents | Class size |
|---|---|---|---|
| This kit (EL-EE-7239) | Dissolved oxygen | Fifty tablets (colour reaction tests) | 40 students |
| Testing Drinking Water | pH, hardness, alkalinity, fluoride, chlorine | Fifty test strips for each test | 40 students |
| Testing Ponds and Streams Kit | Alkalinity, phosphates, pH, nitrates/nitrite | Fifty test strips for each test | 40 students |
The dissolved oxygen kit is the one to choose when students are judging whether a pond or stream can support fish and other aquatic life; the strip kits cover the chemistry of drinking water and of nutrient pollution.
What Is a Dissolved Oxygen Test Used For?
Fish, insect larvae and most other aquatic organisms depend on oxygen gas dissolved in the water. Warm water holds less oxygen than cold water, and when sewage, fallen leaves or other organic waste decompose, the microbes doing the work use up oxygen — so a low reading is often the first sign that a water body is under stress. With this kit, students take samples from a pond, a stream, a fish tank or tap water, run the colour reaction tests, and compare the results between sites, seasons or times of day. The activity supports environmental science and EVS units on water pollution, field projects for eco-clubs, and the idea of biochemical oxygen demand (BOD) in the sewage-treatment section of class 12 biology, as well as introductory courses in colleges.
For reliable results, fill the sample bottle gently without trapping air bubbles and test the sample promptly, because oxygen moves into or out of the water once it is collected. Keep the tablets closed and dry between lessons.
What to Specify When Ordering
- Number of kits — each kit is planned for a class of 40; the minimum order is 10 kits.
- Batch expiry — ask for the expiry date of the tablets you are quoted.
- Sampling equipment — a water sampler lets students collect water from below the surface.
- Delivery details — destination city or port and any packing or labelling instructions.
Frequently Asked Questions
What does the kit measure?
Dissolved oxygen, the amount of oxygen gas present in a water sample, which is a key indicator of water quality.
How does the test work?
It uses tablets for simple colour reaction tests: the colour that develops in the sample is compared to judge the oxygen level.
How many tests can one kit run?
The kit contains fifty tablets. The number of complete tests depends on how many tablets each test uses, so ask us to confirm it with your quotation.
What is the shelf life of the tablets?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Why is dissolved oxygen important?
Aquatic animals need it to survive. Levels drop in warm or polluted water, so measuring it shows students how pollution affects rivers, lakes and ponds.
What details are needed for an export quotation?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, and a tender reference where one applies.
