Features and Benefits:
●
Freezing Point Analyzer for Milk
The CRY-8 is a modern digital analyzer for the
accurate determination of the freezing point
temperature in samples of raw milk or milk products
(skimmed, pasteurized or UHT-milk).
The most objective indicator for the degree of
falsification of milk by additional water is the raising
of the freezing point temperature from > -0.512 °C.
The CRY-8 complies fully with the international
standard ISO 5764/2002(E), IDF 108/2002(E) “Milk” -
Determination of Freezing Point – Thermistor
Cryoscope Method (Reference Method) and Annex
C without the necessity to correct the results to the
reference method.
The analyzer measures temperatures in the range
from below -0.512°C (pure milk) to -0.527°C in
increments of 0.001°C.
●
Peltier Effect
The measuring principle is the freezing point
detection of super cooled liquids based on the
Peltier Effect. On the cold side of an Peltier
element the milk samples are cooled down
below the freezing point in the range 0 to -7°C.
●
1-Point Calibration
One-point calibration –the instrument requires for
calibration only one distillation water
sample. Measurement
corrections are done automatically & entered into
the microprocessor memory. It is an
outstanding advantage of the CRY-8, that calibration is
performed in ONE POINT ONLY. In comparison with this,
competitive analyzers do need 2 or 3 different calibration
points.
Once the CRY-8 is calibrated, the CALIBRATION
REMAINS STABLE the whole day AS LONG AS THE
INSTRUMENT STAYS SWITCHED ON.
●
Aqua Dest - Calibration
The CRY-8 does not need expensive calibration
solutions except distilled water for the zero point. These
features, 1-POINT CALIBRATION and AQUA DEST-
CALIBRATION ARE UNIQUE in the market and they
CONTRIBUTE TO SAVING LABOR TIME AND COSTS FOR
PURCHASE and STORAGE OF EXPENSIVE CALIBRATION
STANDARDS.
●
100μl Sample Volume & disposable measuring
vessel
Precise measuring results from only 100μl sample make the
CRY-8 disposable measuring vessels not require washing
and sterilization.
●
Easy Operation
After the samples in 1.5ml tubes are inserted into the
measuring position the instrument PERFORMS
AUTOMATICALLY THE MEASURING PROCEDURE. FUNCTION
CONTROL and ERROR IDENTIFICATION are also
automatically done by the instrument. High accuracy (+/-
0.002 °C) and repeatability (+/-0.002 °C) of results. Short
measuring time ca 1.5 min. Digitally readout of
temperature °C and %H2O with printout. The printer can be
adapted via RS 232 data port.
●
Simple Installation
The CRY-8 is air cooled and does not need any
connection to cooling water.
●
Robust Housing
The sheet metal housing with epoxy lacquer paint ensures
UTMOST MECHANICAL and CHEMICAL RESISTANCE to the
laboratory environment.
●
Small Dimensions
Small instrument weight and dimensions, big resistance to
vibrations and hard working conditions (humidity max 85%,
ambient temp. 36°C) make the CRY-8 from well applicable
in stationary and field conditions.
