Description

Includes

• Instruction Manual
• 24 x 2mL Sample Tubes
• A Model has 250mL each of 7% and 10% sucrose-equivalent salt calibration standards (-0.422 and -0.621°H); Dual-Range and WR has 125mL each of 100mOsm/kg H2O and 500mOsm/kg H2O standards
• Bath Fluid
• Stirring Wires
• Test-tube Rack
• Spare Temperature Probe

Highly sensitive cryoscopes with reliable operation that automatically lowers bath temperature for high concentrations in research applications. Precision Systems Cryette A and Cryette WR Cryoscopes include all solid-state non-mechanical seven-segment readout with integrating techniques for maximum accuracy and reproducibility.

All models obtain molecular weight, solution concentration and freezing point depression determinations for 2mL samples. Additionally, the WR Model includes a digital readout that presents readings in millidegrees C of freezing point depression and digitally displays bath temperature.

Features

• Choice of three models: Cryette A is a milk cryoscope; Dual-Range Cryette A is used for petroleum applications where water or benzene is the solvent; Cryette WR is a wide-range cryoscope that offers the flexibility of using many solvent types
• Thermoelectric refrigerator reaches operating temperature in less than 15 minutes
• Sample readings made in less than 2 minutes
• Fast-equilibrating 55mL bath ensures exact temperature for each sample; controlled to ±0.1°C
• Precisely controlled air temperature during sample isolation
• Two-step calibration with non interacting controls ensures calibration in less than 5 minutes; also, with long-term stability to ensure infrequent calibration
• Digital display with Special Mode facilitates calibration and allows for observing complete cooling and freezing cycle
• Zero-stable panel meter that senses seed point
• Implement APHA and AOAC Official Methods
• Electrical requirements: 115V 50/60Hz, others available; contact your Fisher Customer Service Representative
• Shipped assembled and ready to use
