Torrey Pines Scientific has announced the new EchoTherm SC20 and SC25 Shaking, Chilling, Heating Dry Bath models. The SC20 is a simple digital unit while the SC25 is fully programmable, having 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 Auto-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 mL centrifuge tubes. Also available are blocks for 2 mL vials, 20 mL 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 tube.
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, storing DNA libraries at the workstation, and more.
