Small sample size

Requiring only 20 µL of sample, OsmoTECH is ideal for sample limited applications.

Embedded web server

Easily and securely view, print and download results remotely from a network web browser.

Integrated barcode scanner

The built-in proximity sensor allows for traceable sample identification and reduces transcription errors.

Dot-matrix printer (optional)

With a simple USB connection, OsmoTECH allows for easy printing and archiving of test results.

21 CFR Part 11 features

Security features of OsmoTECH enable labs to satisfy 21 CFR Part 11 compliance requirements. User accounts are password protected with the ability to link sample ID and user ID to test results for improved traceability. The system requires strong passwords, includes a time stamped audit trail and user passwords are suitably encrypted for data storage.


The OsmoTECH provides secure data transfer to LIS and data management systems via Ethernet and TCP/IP communication protocol. Multiple USB ports provide the ability to easily export data in .PDF or .CSV format. Download of data can be disabled as well.

Industry leading accuracy and precision

OsmoTECH utilizes the industry-preferred freezing point depression method to accurately and precisely determine osmolality.

Time stamp synchronization

Synchronize time on the OsmoTECH to network clock to ensure accurate time stamp and alignment of records.

Built-in quality control

OsmoTECH calculates sample statistics instantly, can issue warnings when quality control is out of range, and allows tracking of quality control data over time with an exportable chart for controls monitoring.

Factory calibrated

The system is factory calibrated and ready to test. Recalibration is only required if quality control is out of specification, or after maintenance.

Plastic corrugate package

TECH500 micro-sample test kit provides product in plastic corrugate to support clean room compatibility.

OsmoTECH is not for patient diagnostic use. Advanced Instruments certifies that the technical features needed for 21 CFR Part 11 compliance are built into OsmoTECH. It is your responsibility to implement the necessary controls in your laboratory to comply with 21 CFR Part 11 requirements.

Testing osmolality is an essential parameter for process control and QC – just one of the many complex operational steps in biopharma manufacturing dedicated to producing a product of predetermined yield, purity and quality.

  • Guarantee quality, potency and consistency during media development and raw material management.
  • Monitor cell culture and fermentation to ensure optimal cell health, and consequently, high product quality and yield.

Ensure precise buffer preparation and prove complete buffer exchange to improve purification efficiency.

Safeguard your biologics as it passes through storage, reconstitution and injection.

Ensure that the final product meets your quality standards and release criteria.
