Ohaus Digital 4 Block Dry Block Heater

The Ohaus Digital 4 Block Dry Block Heater (HB4DG) is a high wattage, constant-temperature dry block heater that is economical, versatile and compact. The 4 block capacity allows you to process multiple samples simultaneously with one device.  This digital model offers exceptional temperature uniformity with outstanding temperature stability.  The easy to use touchpad controls have independent displays for temperature and time.  This unit has overshoot protection at 10 °C above set point and an audible alarm.  

This 4 Block Heater accepts a variety of interchangeable Ohaus modular blocks (sold separately), 4 at a time, accommodating tube sizes from 0.2 mL micro-tubes to 50 mL centrifuge tubes. Samples are heated to temperature quickly and accurately with the PID temperature control. The integrated support rod holder with locking knob accepts the optional External Temperature Probe Kit (item #23157) to monitor actual block or sample temperature.

These heaters are available in 120 and 230 V versions. Each measures 16.9" x 8" x 3.5" and has a temperature range from ambient +5 °C to 120 °C.  The heater can be run in environments from 18 to 33 °C (64 to 91 °F), 20% to 80% relative humidity, non-condensing and comes with a 2 year warranty. Typical applications include incubation and activation of cultures, enzyme reactions, immunoassays, and melting/boiling points.
