Brochures and Enquiry
Technical Data
Sample volume: 10 to 50 µl You need 50 to 100 µl? Click here!Measuring time: approx. 1.3 minutes (50 µl)
Measuring process: Manual freezing initiation, automatic result recognition and storing, push button calibration with memory
Reproducibility: ± 0,5%/±1,5 mosm (50 µl), ± 1%/±3 mosm (10 bis 25 µl), greater value will be the correct one
Measurement range: 0 … 2500 mosm / kg H2O
Power supply: 230V AC (100/115V AC on request) approx. 45 VA
Dimensions: Width 180 mm, height 278 mm, depth 216 mm
Weight: approx. 5.5 kg
The Instrument is CE labelled and WEEE conform.
Accessories included:
50 plastic tubes, 2x10 vials of standard solution 300 and 900 mosm / kg H2O, spare thermistor, spare needle, spare fuses, operating instructions, little awl for cleaning.
Calibration
The zero point is calibrated with distilled water and a standard point with the NaCl-solution of 300 mosm supplied. Occasional checks show that the calibration is very stable. An additional 900 mosm-solution can be used to calibrate, whereby the linearity is raised by higher concentrations.Special Features and Advantages
- Very small sample volumes possible.- Cost effective solution for users with smaller numbers of samples.
- Measurements shown on a wide illuminated LCD display.
- Automatic result recognition and storing ensure reliable measurings.
- User guiding and error messages with lamps and display.
- User friendly push button calibration prevents calibration error.
- Additionally third calibration point at 900 mosm provides increased accuracy at higher concentrated solutions.
- Single use plastic tubes.
- Reduced operating costs as no extra water supply is necessary and power consumption is low.
Operating of the Instrument
- Switch on instrument, wait for ready display (approx. 3 minutes). - Place 25 µl sample in the sample tube (± 10 %). - Place the sample tube onto the measuring head. - Lower the measuring head. The sample tube is dipped into the cooling slot. - Superercooling is reached after 1 minute and the instrument gives an audible tone. The user dips the needle with ice crystals shortly into the sample and starts the freezing manually. - The freezing point will be reached, the display shows the measurement value in mosm / kg. The measuring value will be automatically detected and stored until the next measuring is started. A buzzer sounds and the "Ready" lamp shines. - Slide measuring head from cooling slot and remove the sample tube. - Wipe the thermistor with a soft tissue.
Extra Accessories:
- Analogue output for XY-plotter- Calibration solution 300 and 900 mosm / kg H2O
