Dry Block Heaters
Designed for applications that require repeatable results and superior temperature stability. These multi-purpose units are ideal for incubation and activation of cultures, enzyme reactions, immunoassays, melting/boiling points, and a wide variety of other laboratory procedures. Each of the five models accepts separate interchangeable modular blocks, accommodating various tube sizes from 0.2 mL micro-tubes to 50 mL centrifuge tubes. Each block has a thermometer well for measuring block temperature. Efficient heating due to close tube-and-block contact for maximum heat retention.
Key Features
- Exceptional temperature uniformity and stability
- Optional external temperature probe
- Holds interchangeable modular blocks
- Integral support rod holder with locking knob accepts optional External Temperature Probe Kit
- Optional External Temperature Probe Kit monitors actual block or sample temperature
Digital Models - Operating Features
Microprocessor Control: PID 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. Temperature is adjusted in ± 0.1°C increments.
LED Display: Touch pad controls with easy-to-read, independent LED displays for temperature, and time. Provides repeatable and accurate results every time and is easily visible across lab benches. Shows set-point and actual temperature. Timer will display elapsed time or, when programmed to user defined limit, will shut off unit when time reaches zero. Display will show last used settings, even after power has been turned off.
Temperature Calibration Mode: Allows user to calibrate unit to an external temperature device.
Analog Models - Operating Features
High wattage, constant-temperature Dry Block Heaters are economical, versatile and compact.
Microprocessor Control: PID temperature controller maintains precise temperature control. Samples are heated to temperature quickly and accurately.
Adjustment Knobs: Dual temperature control knobs with dial markings from 1 to 10 for low temperature and high temperature adjustments. Low range knob adjusts from ambient to 100°C and high range knob adjusts from 75°C to 150°C.
Safety Features
- Caution Hot Indicator: Hot warning symbol light is illuminated when the temperature is above 40°C (digital models)
- Overshoot Protection: If the unit exceeds the set temperature by 10°C the unit will automatically stop heating (digital models)
- Audible Alarm: In timed mode, alarm will sound when time reaches zero and when unit reaches set-point temperature (digital models)
CAUTION! To avoid possible electrical hazard, do not fill well or block opening with water or other fluids. Unit is designed as a dry bath/incubator.

What's Included
Units include a detachable, 3-wire cord and plug. Modular blocks are sold separately.
Note: Heaters require modular heating blocks for operation. Modular blocks are sold separately.
Modular Blocks & Accessories
Modular blocks are constructed from a solid anodized aluminum block. The close contact of tubes-to-block walls allow for maximum heat retention. Each block has a thermometer well for measuring block temperature.
Single block dimensions (L × W × H): 3.75 × 3 × 2" (9.5 × 7.6 × 5.1 cm)
Double block dimensions (L × W × H): 6 × 3.75 × 2.25" (15.2 × 9.5 × 5.7 cm)
