Drinking & Process Water
pH, TDS, turbidity, heavy metals (arsenic, lead) and mineral profile analysis.
Water testing →Kolkata · West Bengal · Sample pickup available
Food and water testing in Kolkata, with reports you can hand to an inspector
Drinking water against IS 10500, packaged water against IS 14543, effluent against CPCB norms, food microbiology, shelf life and FSSAI label panels — every parameter reported with its method, its permissible limit and the observed value.

The problem you are probably trying to solve
Most people who call us are not shopping for a laboratory. They have a deadline, an inspection, a complaint or a renewal.
Housing society
Residents say the tank water smells and nobody can prove what is wrong
A full IS 10500 panel on tank and tap water names the parameter that failed, so the committee can act instead of argue.
Drinking water · IS 10500 →Restaurant / cloud kitchen
An FSSAI audit is due and you have no water or food report on file
Water, ice, surface swabs and one or two high-risk items is the smallest set that satisfies most inspections.
Food microbiology →Packaged water plant
BIS licence renewal needs a current IS 14543 report
Full IS 14543 panel on sealed packs, including the parameters most often missed on renewal submissions.
Packaged water · IS 14543 →Food manufacturer
A buyer wants a nutrition panel and a shelf-life claim you cannot substantiate
Nutritional analysis for the label declaration, plus a pull-point shelf-life study to support the best-before date.
Nutrition label panel →Industrial unit
Pollution board wants discharge figures before the consent is renewed
Effluent panel covering pH, BOD, COD, TSS, oil and grease and the metals relevant to your process.
Effluent · ETP / STP →Household with a borewell
New borewell, and you have heard about arsenic in Bengal groundwater
Arsenic has no taste or smell and boiling concentrates it. A one-off test tells you whether treatment is even needed.

How pricing and turnaround actually work
We quote per parameter, not per sample, so you only pay for what is tested. Rather than publish a price list that goes stale, here is the logic behind every quote — ask for the itemised version and you will get it in writing before anything is collected.
Priced per parameter
A single parameter is inexpensive. A full IS 10500 panel with heavy metals costs considerably more, because it is many separate determinations on one sample.
Panels cost less than the sum
Parameters that share a preparation step are cheaper together than ordered individually. Ask for the panel price, not a list of singles.
Turnaround is set by biology
Chemical work moves at the speed of the laboratory. Microbiological work needs incubation that cannot be shortened — usually 24 to 48 hours before a result can even be read.
Pickup and bottles
Sterile bottles are free. Pickup within Kolkata and Howrah is quoted with the test rather than added afterwards.
How a test works, start to finish
Turnaround starts the day the sample reaches the laboratory, not the day you call.
- Tell us the sample and the reasonEnquiry form, phone or WhatsApp. The reason matters more than the sample — it decides the standard.
- Get the parameter list and price in writingParameters, quantity needed, container type, turnaround and cost, before anything is collected.
- Sample reaches the laboratoryDrop at Room 313 or we pick up. Bacteriological samples need sterile bottles and a cold chain within 24 hours.
- Signed report by email and hard copyEach parameter with its method, limit and result, signed by the reviewing analyst.
Sample collection & submission
Collect samples in sterilised containers and tag them with the parameters you need tested.
Standard turnaround: 3–5 working days, confirmed in your quote
Beyond testing
Formulation development & R&D
In-house product rework, troubleshooting, and chemical process optimisation.
Questions we are asked before every first order
How long does a water test take?
A chemical panel is typically a few working days. Bacteriological results need incubation time that cannot be shortened — a coliform confirmation runs 24 to 48 hours before it can be read. We confirm the exact turnaround in the quote, counted from the day the sample reaches the laboratory.
Do you collect the sample or do I send it?
Either. We arrange pickup across Kolkata, Howrah, Salt Lake and New Town, or you can drop the sample at Room 313, Saltee Plaza. For bacteriological testing you must use a sterile bottle — we supply them free before collection, because a sample in a rinsed mineral water bottle cannot give a valid result.
Is the report accepted by FSSAI or the pollution board?
Some submissions require a report from an accredited laboratory. Tell us at enquiry stage who the report is going to and we will tell you plainly whether ours meets that requirement or whether you need an accredited laboratory. We would rather say no than sell you a report you cannot use.
What does a test cost?
Price depends on the number of parameters, not the sample. Send the sample type and the reason for testing and you get an itemised quote, usually within one working day. The pricing logic above explains how the number is built.
Can you tell me what to do about a failed result?
We can explain what the number means and which parameter is out of range. We do not sell treatment equipment or chemicals, so we have no interest in the outcome — for a remedy, take the report to a treatment vendor or consultant. That separation is deliberate.
Can I see a report before I order?
Yes. The sample report page shows the exact format field by field, including the method column and the named signatory, so you can compare it against any other quote you are holding.
