Dri-Block® heater units have a recessed chamber to hold up to two interchangeable insert blocks (in the DB-2A, DB-2D - or one aluminum insert block and two plastic spacers). Three interchangeable insert blocks in the DB-3, DB-3A, and DB-3D. The blocks are made of an aluminum alloy with excellent thermal conductivity and are drilled with a choice of different hole sizes for tubes and containers ranging from 6mm to 26mm diameter. Other blocks are available, including three for 0.5 ml, 1.5ml or 2.0ml microcentrifuge tubes and two alternative sizes undrilled for customers who wish to machine to their own requirements. Each aluminum 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).

A close fit of the tubes in the block ensures high heat transference to the tube and the heater design, temperature sensor and solid state circuitry give exceptionally good temperature control uniformity.

Temperature setting on the DB-2A, DB-3 and DB-3A is by a dial calibrated in degrees centigrade. On DB-2D and DB-3D digital units, the temperature is set by using the “Set” and “up/down” buttons. The large LED panel displays both set point and actual values. Heat up rate on all units is rapid.

Independent lights indicate mains power, heater action and 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.

DB-2A Dri-Block

The DB-2A is designed to take up to two aluminum alloy insert blocks. Temperature setting is by a calibrated knob/ dial in degrees centigrade. Temperature range 25°C to 100°C.

DB-2D Dri-Block

The DB-2D is similar in design to the DB-2A accepting two blocks, but has a red LED display. The temperature is set by using the “Set” and “up/down” buttons. The large LED panel displays both the set point and actual values.

DB-2TC Dri-Block

The DB-2D is similar in design to the DB-2D with an innovative design accommodating two blocks with independent digital temperature controls. Each block can be set at different temperatures - ideal for multiple users or applications where samples have to be transferred between two temperatures very quickly. The temperature is set using the “set” and up/down buttons and is displayed on the LED panel. Temperature range: -100°C

DB-3 Dri-Block

The DB-3 is similar in design to the DB-3A but with a temperature range 25°C to 100°C.

DB-3A Dri-Block

The DB-3A is designed to take three aluminum alloy insert blocks. Temperature setting is by a calibrated knob/dial in degrees centigrade. Temperature range 25°C to 200°C.

DB-3D Dri-Block

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“up/down” buttons. The large LED panel displays both set point and actual values Temperature range 25°C to 200°C.
