Torrey Pines Scientific has announced the new EchoTherm SC20XT and SC25XT models. The SC20XT is a simple digital unit, and the SC25XT is fully programmable with a five-program memory making both ideal for use with biological and other samples.
Both have a temperature range from -20°C to 100°C and incorporate a variable speed orbital shaker for mixing and controlling the temperature of samples simultaneously. Both units have a 30-day count down timer with alarm and automatic shut-off, data logger and RS232 I/O port for data logging or controlling the units from a computer.
The SC20XT and SC25XT accommodate accessory sample blocks available for 0.2, 0.5, 1.5, 15 and 50 milliliter centrifuge tubes. Also available are blocks for 2-milliliter vials, 20 milliliter scintillation vials, PCR tubes and plates, 96-well and 384-well assay plates of all shapes, deep-well assay plates and other blocks for various sizes of test tubes.
The units are Peltier driven, with control to 1°C, shaking range from 200 to 1000 rpm and have a backlit two-line alphanumeric display. These instruments are excellent molecular biology tools and can be used to run temperature/time profiles, unattended restriction digestions or ligations, automatic enzyme reactions and deactivations, storing oocytes at 17°C and storing DNA libraries at the workstation, the company said.
Both units come complete with instructions and universal bench top power supply for use anywhere in the world. They are UL, CSA and CE compliant.
