Torrey Pines Scientific Inc. Model SC25 Fully Programmable Orbital Mixing Chilling/Heating Dry Baths are compact, completely solid state, versatile, reliable, and easy to use. They feature 5-program memory where each program can have as many as 10 steps. 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.

The built-in orbital mixer has 9 digitally preset mixing speeds varying from 200 to 1000 rpm. The orbital mixer is designed with friction free hardened, blued, tempered steel leaf spring bearings that support the plate and sample blocks. The units have a temperature range from -10°C to 100°C at the plate surface. They have an I/O port for recording data or for controlling the unit from a computer. The built-in data logger can store 7825 data points in 1 second, 1 minute or 5 minute intervals. The units also have a built-in 30-day timer with alarm and user settable Auto-Off function that will turn off the chiller/heater/mixer after any count down timed event.

Sample Applications

• 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
• 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/mixing 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
• Store enzymes or DNA libraries at your work station
• Work directly on plate surface
• 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.
