ECHOtherm Model IC25 Digital, Programmable Electronic Chilling/Heating Plate

• 5-program memory
• Electronic calibration--factory set but user settable to any local standard
• Energy-efficient Peltier design
• Digital control to 1°C from -10 to 100°C or to -20 on the XT model
• Control at ambient
• Countdown timer (up to 30 days) with alarm and user settable Auto-Off
• RS232 I/O port for control and data collection
• Universal power supply feeds 12VDC operation

Torrey Pines Scientific’s Model IC25 Programmable, Digital, Electronic Chilling/Heating Plates are compact, completely solid state, versatile, reliable, and easy to use. They run from a manufacturer supplied 12 volt DC power supply. The IC25 has simple digital controls and a two-line alphanumeric display that is backlit for easy reading. The display normally shows the target and actual temperatures. Additionally, it is used to display temperature, timer and all programming functions.

Writing programs is simple as well and done through the up and down arrows on the membrane switch. Calibration is factory set, but calibration is settable by the user to any local standard. Calibration is electronic and accessed through the keyboard and stored in CMOS.

Sample Applications

• 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
• Produce 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
• Maintain 14°C for ligation reactions
• Maintain 17°C for storing oocytes
• Store samples at ice bucket temperatures
• Incubate samples in 96-well assay plates, or in aluminum blocks holding 0.2, 0.5, or 1.5 ml centrifuge tubes
• Cool blood samples prior to coagulation testing
• Store enzymes or DNA libraries at your work station
• Enzyme reactions and deactivations
• Freeze and store most any small sample at your work station

Sample Blocks for Dry Baths
All blocks are precision machined from solid aluminum to exactly fit the tube shape and black anodized for better heat transfer and protection from spills. The bottoms of the blocks are machined to “nest” on the plate to prevent movement.
