Specifications

Description

Cryoscope; Precision Systems; Cryette A; Dual Range; For use w/2mL petroleum samples, automatic 55mL bath controlled to +/- 0.1degreeC; 115V 50/60Hz; Includes instruction manual, 24 2mL sample tubes, 125mL each

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
