  • 5-program memory
  • Energy-efficient Peltier design
  • Digital control to 1°C from -20°C to 100°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 settable to any local standard
  • Compact size. Uses very little bench space
  • 12-month warranty
  • UL, CSA and CE compliant

Applications Include:

  • 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 to 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 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, 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
  • Working directly on large plate surface

Product Description:

The completely solid-state EchoTherm™ IC35 Large, Heavy-Duty, Digital, Programmable, Electronic Chilling/Heating Dry Bath is versatile, reliable and easy to use. The IC35 has 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 is used to display the timer and all programming functions.

The chilling/heating surface is a 5” (12.7 cm) square aluminum plate that is very flat for optimal contact with the sample. When unloaded, the plate will go below 0°C in under two minutes. It will heat to 37°C even faster. Generally, the unloaded surface will decrease temperature at about 3°C/minute. Heating rates on the unloaded plate are usually about 5°C/minute. The blocks sold as accessories range in size and mass depending upon the samples used. The unit can drive the biggest block 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.

The above graph shows a temperature/time profile that can be stored in memory and recalled instantly to be run at any time. The profile was plotted after the data points were collected in buffer. The buffer was then dumped via the RS232 port to a PC. Five programs of as many as ten steps each can be stored in memory. Each step is a temperature and time. Each program can be set to repeat itself up to 99 times.
