Description:

The 3250 automates serum, urine or industrial solution osmolality in 90 seconds. After pipetting 20 µL into the disposable tube, a super-cooled probe induces crystallisation; a platinum thermistor records the freezing plateau and converts it directly to mOsm kg⁻¹ using factory calibration. The micro-controller averages three runs or flags >2 % RSD, then prints results on the integrated thermal printer and stores 1 000 tests in flash. An onboard air compressor supplies the cooling tip—no expendable refrigerant. The front panel selects sample ID and units, and integral QC reminds techs when to run two-point reference solutions.

Economic Advantage:

Because the 3250 needs only 20 µL—half the sample volume of legacy units—NICUs and biopharm labs cut redraws and dilution prep. Combined with maintenance-free freeze electrodes, consumables drop enough to repay an upgrade in roughly 18 months.
