Data Sheet



These Fully Programmable Orbital Mixing Chilling/Heating Dry Baths are compact, versatile, reliable and easy to use. Their 5-program memory allows for each program to have as many as 10 steps, where each step is a mixing speed, temperature and timed event. Additionally, any program can be made to repeat itself from 1 to 99 times automatically.

They are completely solid state and very rugged.  There are more than 30 standard sample blocks available as accessories for use with assay plates, centrifuge tubes, vials, test tubes and more. Custom sample blocks can be made for any sample container.

Units come complete with instruction manual, universal bench top power supply for use anywhere in the world, and AC line cord for the country of use. Sample blocks and covers are available as accessories.


  • Orbital mixing with speeds from 200 to 1000 rpm
  • Energy-efficient Peltier design
  • Digital control to 1°C from -20°C to 110°C (without sample block)
  • Control at room temperature
  • Store 5 programs in memory for instant recall and use
  • 10 steps per program where each step can be a temperature, time and shaking speed
  • 30-day count down timer with audible alarm and user settable Auto-Off
  • RS232 I/O port for control or data collection
  • Built-in data logger
  • Electronic calibration
  • Small compact size uses very little bench space
  • 12-volt DC operation. Universal power supply provided
  • 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 the 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 to 95°C for a given time and rapidly reducing temperature to 4°C to prevent renaturation
  • Automatic temperature/mixing 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, 2-250 and 500ml centrifuge tubes
  • Storing samples at ice bucket temperatures without the mess
  • Incubating samples at 37°C in 96-well assay plates, PCR plates, aluminum blocks for 0.2, 0.5, 1.5, 15ml centrifuge tubes, vials and test tubes
  • Storing enzyme or DNA libraries at your workstation
