Page & Pedersen QuickCheck SELECT Cryoscope

QuickCheck QC-SELECT is a 3-channel cryoscope with extended freezing point determination capabilities for special applications. The QuickCheck Select features extended and amplified super-cooling capabilities. The three (3) channels allow users to calibrate for an extended number of products, broadening the benefits that this reliable, exceptionally robust analytical tool brings to you. By keeping one channel for traditional testing (i.e. screening raw milk for extraneous water) you can then assign and pre-calibrate other channels to test special products such as lactose-reduced milk, ice cream mixes, flavored fluid products, etc.

The Freezing Point Ranges on the 3 channels are as follows:

•  CH-1 from -0.600 to 0.00 °C / -0.621 to 0.000 °H
•  CH-2 from -1.000 to -0.600 °C/°H
•  CH-3a from -2.000 to -1.000 °C
•  CH-3b from -2.800 to -2.000 °C

Channel 1: Testing for adulteration of milk in accordance with current internationally reviewed and recommended reference methods (see ISO 5764:2009, IDF 108:2009 and AOAC 990.22-1993), the QC-IV/GR provides ultra-accurate results in ~ 90 seconds. Can be used for Cow, Goat, Sheep, Camel and Water Buffalo milk testing.

Channel 2: Designed for Lactose Hydrolysis testing, to ensure solid enzymatic conversion of Lactose to its constituent sugars, glucose and galactose, for reduced lactose or lactose free milk. Can also be used for other process control where the freezing point is between -0.600 °C and -1.000 °C (i.e. Dextrose Equivalency). Finally, it can be used for testing water added in Yak (FP: -0.724 °C) and Zom milk (FP: -0.697 °C)

Channel 3: can be user selected for two different ranges a) -2.000 °C to -1.000 °C or b) -2.800 °C to -2.000 °C. This channel is used for ice cream mix (mixture dependent), chocolate milk, and a big variety of flavored, dairy-based products.

The calibration of all parameters is independent and individual for all channels. Beside the normal adjustable parameters, the QC-SELECT also has a new parameter for Freeze Pulse Temperature cut in. The parameters adjustable by the user include:

• Stir Amplitude (0-100%)
• Freeze Pulse Amplitude (0-100%)
• Freeze Pulse Duration (0.5 to 2.0 seconds)
• Freeze Pulse Cut-In Temperature (-3.000, -3.500, or -4.00°C / °H)
• Bath Temperature (down to -9.0°C)
• Freezing Point Method (Plateau, Time, Max)

QC-SELECT Start-Up Kit Includes: 1 x Bath Liquid (Cooling Transfer Fluid – 500mL), 1 x AC Power Cord, 1 x User’s Manual, 12 Sample Tubes, 1 each 422 & 621°H Calibration Standards (125mL), 1 x 530°H Calibration Control (125mL)

Compliant with AOAC 990.22-1993, IDF 108C:2009 & ISO 5764:2009
