SubscribeTechne Dri-Block® heaters are the economical answer to every laboratory’s need for a compact constant temperature heater.
Dri-Blocks are particularly suitable for microbiology and clinical laboratories for incubation, boiling, inactivation, wet ashing, sample concentration, enzyme analysis and other general uses. They are also used for a variety of industrial applications. The heat transfer medium is an aluminium alloy block with machined cavities to accept the tubes or sample containers.
Construction
Dri-Block ® heater units have a recessed chamber to hold interchangeable insert blocks. The DB-2A and DB-2D can hold up to two aluminium insert blocks or one 96-well plate block. The DB-3, DB-3A and DB-3D can hold up to three insert blocks or one 96-well plate.
If the full compliment of insert blocks are not used, plastic spacers can be employed to bridge the gap in the recess of the unit The blocks are made of an aluminium which has excellent thermal conductivity and are drilled with a choice of different hole sizes for tubes or containers, ranging from 6mm to 26mm diameter.
Other blocks are available, including three for 0.5ml, 1.5ml or 2.0ml microcentrifuge tubes and two alternative sizes undrilled for customers who wish to machine to their own requirements. Each aluminium alloy insert block has a threaded thermometer hole which also accepts the insert block extraction tool for ease of removing insert blocks from the heated chamber (not applicable to insert blocks reference F4467, F4468, F4469). Custom blocks can be made upon request to the Techne Sales Office.
A close fitting of the tube ensures a high heat transference and the heater design, temperature sensor and solid state circuitry give exceptionally good temperature control uniformity. Independent lights which indicate mains power, heater action and over-temperature conditions are incorporated and an on/off switch is mounted on the rear panel. The units are strongly constructed, light in weight and have extremely efficient insulation to ensure that the case remains cool enough to handle even at maximum operating temperatures.
Safety
The Dri-Block® range has been designed to comply with all RF interference and electrical safety regulations.
THE DB-2A
The DB-2A is designed to take up to two aluminium alloy insert blocks.
Temperature setting is by a calibrated knob/dial in degrees centigrade.
Temperature range 25°C to 100°C.

one aluminium insert block and two plastic spacers.
The DB-2D
The DB-2D is similar in design to the DB-2A but has a red LED digital display.
The temperature is set using the set and the or buttons and is displayed on the LED panel.
The DB-2D can also be supplied with an RS232 connection for software control*.
* The DB-2D with RS232 connection is supplied with a 2 metre long RS232 cable.
The DB-3
The DB-3 is designed to take three aluminium alloy insert blocks.
Temperature setting is by a calibrated knob/dial in degrees centrigrade.
Temperature range 25°C to 100°C
The DB-3A
The DB-3A is similar in design to the DB-3 but with a temperature range of 25°C to 200°C
The DB-3D
The DB-3D is similar in design to the DB-3A but has a red LED digital display. The temperature is set using the set and the or buttons and is displayed on the LED panel. Temperature range 25°C to 200°C. The DB-3D can also be supplied with an RS232 connection for use with software control*.
