Advanced Instruments 3250 Freezing Point Osmometer for Clinical and Laboratory Use
Product Description
The Advanced Instruments 3250 Osmometer is a high-precision laboratory instrument designed for accurate osmolality measurement via the freezing-point depression method. It utilizes a 0.20 to 0.25 mL sample volume, ideal for standard specimen testing in clinical diagnostics and biochemical research.
Key technical features include:
- Microprocessor-controlled operation with automated freezing-point detection and temperature sensing for consistent results.
- Measurement resolution of 1 mOsm/kg H₂O and excellent linearity with less than 0.5% deviation at reference conditions.
- High repeatability: standard deviation <2 mOsm/kg H₂O for 0–400 mOsm and <0.5% for 400–4000 mOsm range, ensuring reliability in long-term use.
- Measurement ranges from 0 to 2000 mOsm/kg H₂O (low) and 1400 to 4000 mOsm/kg H₂O (high), supporting diverse clinical and biotechnology applications like molecular diagnostics and bioprocessing quality control.
- Single-sample capacity with an easy-to-read 20-character vacuum fluorescent display and multiple communication options including onboard printer and RS-232 serial port compatibility.
- Rugged design with compact 13x18x16 inch dimensions and 23 lbs weight, suitable for standard laboratory benchtops.
- Power compatibility of 100–240V, 50/60Hz to accommodate global laboratory settings.
This osmometer is essential for molecular biology workflows requiring precise osmolality analysis such as gene editing verification, synthetic biology experiments, and biopharmaceutical production pipelines. Its robust performance metrics meet the demands of clinical labs and research facilities conducting fluorescence analysis, live-cell imaging preparations, and other biotechnological investigations.
For lower sample volume needs, consider the Advanced Instruments 3320 Micro-Osmometer, which operates with 20 µL micro-samples, complementing workflows where specimen conservation is critical.
Overall, the Advanced Instruments 3250 Freezing Point Osmometer delivers reliable, reproducible osmolality data critical in molecular diagnostics, clinical chemistry, and bioprocess monitoring, making it a staple analytical tool in bioscience laboratories.
