Multi-purpose, high wattage, constant temperature, VWR® digital block heaters are economical, versatile and compact. These digital models provide reproducable results, exceptional temperature uniformity, and are ideal for a wide range of applications. Temperature calibration mode allows the user to calibrate the unit to an external temperature device. In timed mode, an alarm will sound when the time reaches zero and the unit reaches set point temperature.

• Compact design with small footprint
• Temperature range from ambient +5 to 120 °C
• 'Hot' symbol warning light is illuminated when the temperature is above 40 °C
• Accommodates VWR® interchangeable modular heating blocks for tubes from 0,2 to 50 ml capacity
• Can be used at 18 to 33 °C, with 20 to 80% relative humidity, non condensing

These multi-purpose units are ideal for incubation and activation of cultures, enzyme reactions, immunoassays, denaturing proteins, DNA applications, ELISA, melting/boiling points, and a variety of other laboratory procedures.

Microprocessor control: PID microprocessor temperature control, with optional external RTD probe, offers a temperature stability as low as ±0,1 °C, with a temperature uniformity as low as ±0,1 °C. Samples are heated to temperature quickly and accurately, heat-up time to 100 ºC is 16 minutes. Temperature is adjusted in 0,1 °C increments.
LED display: Touch pad controls with easy to read, independent LED displays for temperature and time. Shows set point and actual temperatures. Timer displays elapsed time or, when programmed to user-defined limit, will shut off unit when time reaches zero.

Units have separate interchangeable modular heating blocks, which accommodate various sample containers such as microtubes, centrifuge tubes, vials, microplates and PCR strips or tubes. Blocks include a thermometer well, and feature close 'tube and block' contact for maximum heat retention. All dry block heaters include a built-in support rod holder for mounting the probe kit.
