Designed to ensure osmometers’ optimal performance and accuracy of test results across instrument reportable range.

Confidence in Your Osmolality Testing

Our line of biotech calibrators and controls are used on osmometers across bioprocessing workflows. These products are designed to ensure osmometers’ optimal performance and accuracy of test results across instrument reportable range.

Osmolality is considered a critical quality attribute and critical process parameter in bioprocessing. Using our calibrators and controls to ensure the results are accurate and precise—protecting the quality of your batch samples. These products work hand in hand with our osmometers to comply with the pharmacopeia guidelines listed below to perform osmolality testing, calibration and verification.

• United States Pharmacopeia
• European Pharmacopeia
• Japanese Pharmacopeia
• Chinese Pharmacopeia

Trusted Results With Streamlined Daily Checks

According to the Pharmacopeia guidelines for osmolality testing, it is important to perform a daily calibration check or verification prior to testing your samples, therefore ensuring instrument calibration and performance. Our Calibrators and Controls are manufactured to a tight tolerance so you can quickly spot shifts in performance.

Our osmometers are factory calibrated. You only need to use the Clinitrol™ 290 and require minimum testing prior to use.

During the preventative maintenance, we recommend the use of the linearity set to verify the calibration check which ensures the accuracy of the result and monitors a full range of instrument performance.

Dedicated to Quality

With more than 65 years of experience in osmolality testing, our Quality Management System is certified according to ISO 9001 and ISO 13485.

  • Each lot of our osmolality standards is tested and analyzed by our laboratory using an osmometer that is calibrated against NIST Traceable Reference Solutions to ensure accurate and precise testing.
  • Certificates of Analysis (COA) are available for each specific lot, providing all required information about the standards. For your convenience, these COAs are available electronically on our website.

Clinitrol­™ 290 for Calibration Check


Controls for Sample Osmolality Check


Osmolality Linearity Sets for Range Validation


Protinol™ Control for Protein Based Samples


Easy & Ready-to-use

Our Calibrators and Controls are pre-mixed with the right concentration of Sodium Chloride in individual ampules available in either 2 mL or 5 mL. The ampules are designed to be easily opened and ready-to-use.

Open a new ampule before each test. These can be used straight out of the box and are specifically made to work with our osmometers.

Calibration For Peace of Mind

Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. Calibration precisely adjusts the osmolality of the instrument using the our calibration standards.

Our instruments are calibrated with a minimum of two points and comply with the pharmacopeia guidelines.

Please see the table below for the different calibration points used for our osmometers. The zero point calibration standard is used to determine the lowest osmolality value of the instrument to be compliant with the European Pharmacopeia.


Calibration Standards required for Our Osmometers for Biotech

Low Range (mOsm/kg) 0, 500, 1500 0*, 50, 850, 2000* 0*, 50, 850, 2000* 0, 300, 850, 2000 100, 900, 2000

What our customers say

We had a demo of the [OsmoTECH PRO] instrument after seeing it at BPI East. The sales managers were prompt in setting up a lunch and learn. The instrument itself was very easy to run samples on and allowed for true load and walk away functionality. The sales managers were thorough professionals, waiting for our PO to go through and working with us to ensure we received the item within a week of ordering. It has the ability to run 20 samples at a time and is great value for the money spent.

Kanaka Bhere

Boehringer Ingelheim Animal Health

The [OsmoTECH PRO] instrument is extremely effective, easy to set up and validate, gives quick results and is extremely accurate.

David Longino

Aspek Pak

The [OsmoTECH PRO] is great for accurate and precise osmolality, giving reliable and reproducible measurements.

Varun Khurana


This [OsmoTECH] instrument was a dream come true. The administrator can lock down features and dictate what users can and cannot do. Very easy to use and extremely reliable instrument.

Troy Franz

Paragon Bioservices

The best part of the [OsmoTECH] instrument is it gives accurate and reproducible results for any solution and most importantly in less than a minute you have the results.

Brijeshkumar Pandya

Nivagen Pharmaceuticals Inc.

[The OsmoTECH] achieves high quality and reproducible results. Easy instrument to use and well-presented software.

Claudia Chadford

Touchlight Genetics

[The OsmoTECH PRO] instrument is simple to operate with minimal consumables.

Greg Hautke

Baxter Healthcare

This [OsmoTECH PRO] osmometer is an accurate and convenient tool for the needs of our lab. Our lab works in the developmental stage of pharmaceuticals, and requires quick, precise bursts of osmolality checking for QC - and this instrument (with a load capacity of 20 samples) takes care of those needs. With developmental drugs, limited sample volume is often an issue - this instrument only needs 30uL (and takes ~90 seconds a measurement).

Sasha Sheptovitsky

Alexion Pharmaceuticals

Osmolality measurements are easy and reliable with this [OsmoTECH PRO] instrument.
