Automatic osmometer OsmoTouch 20

carouselfor biological samplesfor pharmaceutical applications

Overview
OsmoTouch 20 is an automatic osmometer with a 20-place carousel autosampler for rapid determination of freezing‑point depression (osmolality) in biological fluids, pharmaceutical samples and other solutions. The instrument features a 7" colour touchscreen, real‑time freezing curve visualization, stable memory for over 4,000 results, CryoSoft Touch PC software for data management, USB ports for data export and firmware updates, and an optional barcode/QR‑code reader. Device functions support FDA 21 CFR Part 11 requirements, including Audit Trail, two user levels (administrator and user), and timestamped, user‑identified unmodifiable results.

Applications
Compact footprint and robust design make OsmoTouch 20 suitable for clinical laboratories, hospital departments, pharmaceutical quality control and R&D. It operates reliably at ambient temperatures up to +36°C and is adapted to the analysis of semi‑viscous biological and formulation samples.

Key features

• Real‑time graph of sample temperature (freezing curve) during each analysis
• Ability to assign a 20‑character alphanumeric ID to each sample
• Optional USB barcode/QR reader for fast sample identification
• Colour‑coded results for rapid detection of anomalies or critical values
• Features for FDA 21 CFR Part 11 support: Audit Trail, two password levels, masked passwords, electronic signature (date/time/username) and non‑modifiable results
• Storage for up to 3 calibration curves based on analytical ranges
• Stable memory for more than 4,000 results
• Easy export of results to USB pen drive and firmware updates via USB
• Real‑time PC monitoring and fast data download with CryoSoft Touch
• Immediate on‑screen error messages

Media
Embedded demonstration video and screenshots of the CryoSoft Touch interface are available to show operating screens and analysis graphs.
