The Picarro Continuous Water Sampler (CWS) A0217, incorporates a porous membrane that enables diffusive sampling of water isotopes. When coupled with a Picarro L2130-i or L2140-i water isotope analyzer, high-resolution, real-time, continuous measurements of spatial and temporal features within water masses are simple and easy.
- Continuously monitor real-time changes in water isotopes
- Automated switching from samples to standards for calibration
- Pump directly from your water source—no discrete sampling required
- Quick and easy field deployment
δ18O precision from continuous water sampling is 0.1‰ and reproducibility is 0.4‰. δD precision from continuous water sampling is 0.2‰ and drift is 1.0‰. The precision, reproducibility, and simplicity open new opportunities for scientists to study the global water cycle over a broad range of applications, including during tidal mixing, at an outlet glacier, or during an ocean transect.
PICARRO CWS (A0217) in Thailand
The Picarro CWS A0217 is a continuous water sampler that draws water isotopes across a porous membrane so a coupled analyzer can read them live, and Thai Unique supplies and supports it in Thailand.

Where the continuous water sampler is used in Thailand
Based on the specifications above, the CWS A0217 suits laboratories that:
- Need to follow how water isotopes shift through a water body minute by minute, instead of filling bottles and analysing them back at the bench.
- Work with a Picarro L2130-i or L2140-i water isotope analyzer and want to feed it straight from the water source, with no discrete sampling step.
- Want δ18O measured to 0.1‰ precision and 0.4‰ reproducibility, and δD to 0.2‰ precision with 1.0‰ drift, from water sampled continuously.
- Need a rig that goes out into the field — tidal mixing zones, an outlet glacier, an ocean transect — and switches between samples and standards for calibration on its own.
Service and support in Thailand
An analytical instrument does not end at delivery. Thai Unique supports yours from within the country.
- Installation and calibration — our engineers install the system, run performance verification and calibrate it for your actual workload
- Scheduled preventive maintenance — year-round cover under a Service Contract, with costs you can budget for
- Repairs with genuine spare parts — experienced technicians using original components from the manufacturer
- Operator training — classroom and hands-on training on your own instrument
- Sample testing and method verification — we run your real samples and verify the method before you commit
Frequently asked questions
Which analyzers can the CWS A0217 be paired with?
It is designed to couple with a Picarro L2130-i or L2140-i water isotope analyzer, which does the actual isotope measurement while the CWS handles sampling. To confirm it fits the analyzer your lab already runs, talk with our Thai Unique team.
Why buy PICARRO CWS (A0217) from Thai Unique rather than direct from the manufacturer?
Because the people who look after it are here. Installation, calibration, scheduled maintenance, repairs with genuine parts and operator training are all handled by our team in Thailand, without routing every request overseas.
Can we test our own samples before deciding?
Yes. Our sample testing and method verification service runs your real samples so you can see the results this continuous water sampler gives on your workload before you buy.
How much does it cost, and how do we request a quotation?
Pricing depends on the configuration, accessories and the scope of work in your laboratory. Tell our sales team what you need to analyse and how many samples you run per day, and we will propose a configuration together with lead time and service terms.
