Planning to test borewell water, drinking water or water used in your business? Correct sample collection is an important first step. A contaminated container, unclear label or delayed delivery can affect whether a sample is suitable for analysis.
To submit a water sample for laboratory testing in Chennai, first confirm the required tests with the laboratory. Obtain approved containers, follow the collection instructions, label each sample, complete the test request form and deliver it within the specified conditions and timeframe.
Here is how to prepare your submission to Tamilnadu Test House.
1. Explain Your Water Testing Requirement
Tell the laboratory where the water comes from and how it is used. Mention whether the sample represents borewell water, municipal supply, treated drinking water or another source.
Explain any concerns, such as unusual colour, odour or a change after treatment. If testing is required for a customer specification or compliance purpose, share that requirement beforehand.
Explore water testing services in Chennai to discuss the appropriate analysis.
2. Confirm the Container and Sample Quantity
Ask the laboratory which containers are required and how much water to collect. Requirements vary depending on the analysis.
Microbiological testing may require sterile containers, while certain chemical tests need specific bottles or preservatives.
Do not assume a reused drinking-water bottle is suitable. Avoid rinsing a laboratory-supplied bottle unless instructed, particularly when it contains a preservative. Never add chemicals yourself without laboratory guidance.
3. Follow the Sampling Instructions
The correct collection procedure depends on the sampling point and testing purpose.
For example, assessing water from a source may require a different approach from checking water as it reaches a consumer’s tap.
Ask whether any preparation, flushing or special collection procedure is necessary. Avoid touching the inside of the bottle or cap, and close the container as instructed.
If you cannot follow the required procedure, discuss professional sampling options before collecting.
4. Label Every Sample Clearly
Label samples immediately so the laboratory can identify them correctly.
Include the sample identification, water source, collection location, collection date and time, and collector’s name where requested.
For multiple samples, use distinct labels such as “Borewell Before Treatment” and “Kitchen Tap After Treatment.” Ensure these names match the accompanying paperwork.
5. Complete the Test Request Form
Provide your contact details, sample descriptions, requested tests and reporting requirements.
Tamilnadu Test House provides a test request form through its downloads page.
Confirm charges, payment arrangements and expected reporting timelines before dispatch. If you need results assessed against a particular specification, identify it clearly rather than requesting a general “water quality test.”
6. Arrange Suitable Transport and Delivery
Ask the laboratory about temperature control, packaging and the maximum permitted time between collection and analysis.
There is no single delivery deadline suitable for every water test. Some parameters require particularly prompt handling.
Secure bottles against leakage, keep documents separate from moisture and coordinate delivery with laboratory receiving hours. Confirm instructions before using a courier.
