Data Sheet



These completely solid-state Digital, Programmable Chilling/Heating Dry Baths are versatile, reliable and easy to use. They have simple digital controls and a two-line alphanumeric display that is backlit for easy reading. The display shows both the target and actual temperatures. Additionally, it displays the timer and all programming functions.

We offer two chilling/heating surface sizes for the aluminum plate that is very flat for optimal contact with the sample or sample block. When unloaded, the plate will go below 0°C in under two minutes. It will heat to 37°C in even less time. Generally, the unloaded surface will decrease temperature at about 5°C/minute. Heating rates on the unloaded plate are usually about 3°C/minute. The blocks sold as accessories range in size and mass depending upon the samples containers used. The unit can drive a block for 1.5 ml centrifuge tubes from ambient temperature to 4°C in less than 30 minutes. When used with an accessory cover these blocks can be driven below 0°C. Temperature gradients from the center to the edge of any accessory block will be less than 0.5°C at any temperature.


  • 5-program memory
  • Energy-efficient Peltier design
  • Digital control to 1°C from -20°C to 110°C without sample block
  • Control at ambient
  • Built-in data logger
  • Count down timer (up to 30 days) with audible alarm and user settable Auto-Off
  • RS232 I/O port for data collection
  • Electronic calibration. Factory set, but user can set to any local standard
  • Small, compact size. Uses very little bench space
  • 12-volt DC operation. External power supply provided
  • 12-month warranty
  • UL, CSA and CE compliant


  • Unattended restriction digestions or ligations at elevated temperatures then reducing temperature to 4°C automatically to reduce non-specific nuclease digestion of target DNA
  • Automatically stopping reactions by having the unit reduce sample temperature after a specific reaction time
  • Producing denatured probes or single stranded DNA molecules by heating to 90°C/95°C for a given time and rapidly reducing temperature to 4°C to prevent renaturation
  • Automatic temperature profiles to grow bacteria at 37°C, then increasing temperature to induce events, and then lowering temperature to 4°C to prevent degradation
  • Maintaining 14°C for ligation reactions
  • Enzyme reactions and deactivations
  • Maintaining 17°C for storing oocytes
  • Storing reagents at 4C in 15, 50, 250, and 500ml centrifuge tubes
  • Storing samples at ice bucket temperatures without the mess
  • Incubating samples at 37°C in 96-well assay plates or in aluminum blocks holding 0.2, 0.5 and 1.5 ml centrifuge tubes, vials, and test tubes
  • Storing enzyme or DNA libraries at your workstation
  • Freezing and storing most any sample at your workstation
