EchoTherm™ SC25 Fully Programmable Orbital Mixing Chilling/Heating Dry Bath

Optional Model:

*XT Model: Chilling range expanded to -20°C without sample block. Recommended for holding samples steady at low temperatures without cycling.
*XR Model: Dual Peltier modules for extra power and expanded heating to 110°C without sample block. Recommended for larger loads and for cycling temperatures up and down.

SC25 $2,840.00
SC25XT $3,120.00
SC25XR $3,120.00

SC25—10 Step Sample Program, 2 Cycle, Orbital Shaker Enabled

Applications Include:

  • 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

Product Description:

The completely solid-state EchoTherm™ SC25 Fully Programmable Orbital Mixing Chilling/Heating Dry Bath is compact, versatile, reliable and easy to use. The 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.

The built-in orbital mixer is designed with friction free hardened, blued, tempered steel leaf spring bearings that support the plate and sample blocks.

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.
