Surge Scientific · Model OSM100100 · Single-Sample Freezing Point Osmometer
Single-Sample Freezing Point Osmometer
<90 Sec · 60 µL Sample · 0–3000 mOsm/kg · Refrigerant-Free
Test in <90 Seconds · 60 µL Sample Volume · 0–3000 mOsm/kg Range · Multipoint Calibration · Refrigerant-Free Cooling · Audit Trail · User Access Control · Built-in Printer · RS232 / USB / LIMS · 4-inch or 7-inch Android Touchscreen (Advanced)
The OSM100100 is the single-sample freezing point osmometer built for clinical chemistry, pharma bioprocess monitoring, and any lab where rapid individual osmolality measurements come up multiple times per shift. Test in <90 seconds with just 60 µL of sample. 0–3000 mOsm/kg measurement range with multipoint calibration. Refrigerant-free cooling means no compressor maintenance, no refrigerant management, no refill schedule — just a quieter, lower-maintenance instrument that runs longer between service intervals. Audit Trail function + User Access Control + RS232 for LIMS/HIS integration hit the regulatory documentation requirements that clinical and pharma environments actually demand. Advanced models add 4-inch or 7-inch Android touchscreen with USB ports for keyboards, scanners, and external storage.
Why Refrigerant-Free Cooling Changes the Maintenance Math
Most freezing point osmometers cool their sample chamber using a refrigeration compressor with R134a, R600a, or similar refrigerant. It works — but it adds compressor noise, vibration that can disturb sample readings, refrigerant leak risk, and a service-and-recharge schedule that adds up over the instrument's lifetime. For labs in space-constrained clinical settings, compressor noise and vibration are real workplace issues. For pharma QC environments under increasing environmental compliance pressure, refrigerant management is real regulatory overhead.
The OSM100100's refrigerant-free cooling system uses solid-state thermoelectric (Peltier) cooling instead — no compressor, no refrigerant, no vibration. The instrument is quieter, runs longer between service calls, has no refrigerant leak risk, and skips the environmental compliance overhead entirely. Combined with the <90 second per sample read time and 60 µL sample volume (lower than most competing osmometers), it's an instrument designed for the long-haul reliability that high-volume clinical and pharma operations actually require.
<90 Sec · 60 µL Sample
Read in less than 90 seconds using just 60 µL of sample. 0–3000 mOsm/kg range with multipoint calibration covers everything from dilute aqueous solutions to concentrated pharmaceutical formulations.
Refrigerant-Free Cooling
Solid-state thermoelectric cooling — no compressor, no refrigerant, no vibration. Quieter operation, longer service intervals, no refrigerant compliance overhead.
Audit Trail + User Access
Audit Trail function, User Access Control, automatic data processing/storage. Regulatory-grade documentation built in for FDA / GMP / 21 CFR Part 11–style environments.
LIMS/HIS Connectivity
Built-in printer + RS232 + USB ports for LIMS / HIS integration. Connect external keyboard, mouse, or scanner. Advanced models add 4-inch or 7-inch Android touchscreen.
"<90 seconds. 60 µL. Refrigerant-free. Audit-trail equipped. The clinical-and-pharma-grade osmometer that runs longer between service calls than the one you're replacing."
