OPERATING PROCEDURE
- Switch on (run-up time 3 minutes)
- Transfer 100µl of sample into the sample tube
- Attached the tube to the measuring head
- Slide the measuring head down, insert tube into the cooling cone
- Supercooling is reached in about 1 minute and shortly after, the seeding needle is automatically inserted into the sample vessel
- The freezing point is determined and osmolarity is shown on the digital display. An audible signal indicates the measurement has been completed.The measurement value is stored in the memory
- Raise the measuring head, remove sample tube and wipe thermistor with a soft tissue
CALIBRATION
The sample volume may be 50µl or 100µl but calibration and measurement must always be carried out on the same volume. Zero is set using distilled water, and the instrument is calibrated against a 300m/Osm/kg water standard (20 ampoules supplied.) Only occasional checks are necessary.
