JJS Tech discontinued Microtox service. Rematek is the authorized alternative.
JJS Tech has ended cleaning and calibration for Modern Water Microtox and Deltatox analyzers — leaving thousands of active units without a published authorized servicer. Rematek picks up exactly that work as a Modern Water–authorized representative, with a certified flat rate below JJS Tech’s former pricing on every instrument.
Authorized Modern Water service representative for 30+ years
JJS Tech's former pricing vs. Rematek's flat rate
JJS Tech has discontinued cleaning and calibration of Modern Water Microtox and Deltatox analyzers. Rematek is the authorized service alternative — offering the same certified cleaning and calibration as a Modern Water–appointed representative, at a flat rate below JJS Tech’s former list pricing on every instrument.
| Instrument | JJS Tech (discontinued) | Rematek flat rate | You save |
|---|---|---|---|
| Microtox Model 500 | $1,912.50 | $1,495.00 | Save $417.50 |
| Deltatox I & II | $1,912.50 | $686.00 | Save $1,226.50 |
| Microtox LX | $1,702.50 | $1,495.00 | Save $207.50 |
| Microtox FX | $739.50 | $686.00 | Save $53.50 |
| RPA I & II fluorimeters | Not offered | $825.00 | Authorized service available |
Rematek flat rates include certification documentation and most required repairs; any parts required are additional. JJS Tech listed item #555934 for both the Microtox M500 and Deltatox, so the Deltatox saving compares that former $1,912.50 listing to Rematek's $686.00 flat rate.

Cleaning & calibration ships with a Certification of Quality.
A certified cleaning and calibration comes back with a signed Certification of Quality — your formal report and proof of service. It declares the unit meets or exceeds its original design and test parameters, and documents the standards and functional checks behind that result. A repair-only job is different: if you simply need the instrument diagnosed and running again, that's exactly what we do — no calibration certificate is issued.

JJS Tech alternative — common questions
- Did JJS Tech stop servicing Modern Water Microtox instruments?
- Yes. JJS Tech has discontinued its cleaning and calibration services for Modern Water instruments — its listings for the Microtox M500 and Deltatox (#555934), Microtox LX (#555935), and Microtox FX (#555930) are all marked Discontinued. Rematek now provides this service as an authorized Modern Water service representative.
- Where can I get my Microtox calibrated now that JJS Tech discontinued service?
- Rematek, LLC performs certified cleaning and calibration of the Microtox M500, LX, FX, Deltatox I & II, and RPA I & II as an authorized Modern Water service representative. Instruments are serviced and returned with a signed Certification of Quality, typically within about 72 hours on the bench.
- Is Rematek an authorized Modern Water service provider?
- Yes. Rematek is an authorized Modern Water service representative and has serviced these exact analyzers for more than 30 years. That manufacturer authorization is what makes Rematek's calibration and performance verification on the Microtox, Deltatox, and RPA instruments defensible for compliance reporting.
- How much does Rematek charge compared to JJS Tech?
- Rematek's flat rates fall below JJS Tech's former list pricing on every instrument: the Microtox M500 is $1,495 (versus $1,912.50), the Microtox LX is $1,495 (versus $1,702.50), the Microtox FX is $686 (versus $739.50), and the Deltatox is $686 (versus the former $1,912.50 M500/Deltatox listing) — a saving of up to $1,226.50.
- What's included in Rematek's cleaning and calibration?
- Each certified cleaning and calibration includes a full functional check, NIST-traceable calibration, and a signed Certification of Quality documenting the result against ISO 11348-3, DIN 38412, and ASTM D5660 tolerances. Most required repairs are included in the flat rate; any parts needed are additional.
- How long does Rematek service take?
- Turnaround is typically about 72 hours once the instrument is on the bench, barring unforeseen issues, which are rare. Instruments are returned on Rematek's FedEx account with shipping added to the invoice, or via your own carrier if you prefer.
