DB-3 and DB-3A OPERATOR’S MANUAL THE DRI-BLOCK® Please read all the information in this manual before using the unit. Techne's Dri-Block® heaters provide a safe, dry, constant temperature source in the laboratory. You can use the units for incubation, boiling, inactivation, wet ashing, sample concentration, enzyme analysis and many other clinical and industrial purposes.
DB-3 and DB-3A OPERATOR’S MANUAL SPECIFICATION The DB-3 Dri-Block® This unit has a recessed chamber which can hold up to three interchangeable insert blocks which accept test tubes or other sample containers. Temperature is set by a front panel dial marked in degrees Celsius. The DB-3 is supplied with an extraction tool for removing the insert blocks from the unit. Temperature range 25°C to 100°C Temperature stability ±0.
DB-3 and DB-3A OPERATOR’S MANUAL The DB-3A Dri-Block® This unit has a recessed chamber which can hold up to three interchangeable insert blocks which accept test tubes or other sample containers. Temperature is set by a front panel dial marked in degrees Celsius. The DB-3A is supplied with an extraction tool for removing the insert blocks from the unit. Temperature range 25°C to 200°C Temperature stability ±0.
DB-3 and DB-3A OPERATOR’S MANUAL Working Environment (all units) The Dri-Block® units are designed to work safely under the following conditions: Ambient temp. range 5°C to 40°C Humidity Up to 95% relative humidity, non-condensing Note: The control specifications are quoted for an ambient temperature of 20°C for units fitted with 2 or 3 insert blocks type F3506, or an F4467 in the case of the DB-1M. The specification will be closely held if the ambient temperature is in the range 10°C to 30°C.
DB-3 and DB-3A OPERATOR’S MANUAL OPERATION Preparation 1. Select the insert block(s) appropriate to the application. A list of available blocks is given on page 22 of this manual. Ensure that both the underside of the block(s) and the top of the hotplate are clean; efficient heat conduction between these two surfaces is essential. Top view showing three insert blocks in place 2.
DB-3 and DB-3A OPERATOR’S MANUAL Setting the Overtemperature Cut-out DB-3 In the event of a fault occurring which could cause the heater to remain on, power is removed from the heater when the block temperature reaches approximately 110°C. DB-3A An adjustable overtemperature cut-out is fitted to these units. As supplied it is set to remove power from the heater should the block temperature exceed approximately 210°C.
DB-3 and DB-3A OPERATOR’S MANUAL Setting the Operating Temperature 1. Turn the temperature control knob to the required temperature. Note that the actual temperature of the block critically depends on the type of block used and the quality of the thermal contact between the base of the block and the unit. 2. The heater (and heater indicator) comes on if the set temperature is higher than the current block temperature. 3.
DB-3 and DB-3A OPERATOR’S MANUAL After Use 1. When you have finished heating samples, remember that parts of the unit – the tubes, blocks and associated accessories – may be very hot. Take the precautions listed earlier. We recommend that the blocks should be allowed to cool to 70°C before being removed from the Dri-Block®. They will still have to be handled with care 2.
DB-3 and DB-3A OPERATOR’S MANUAL ADDITIONAL INFORMATION Insert Blocks Insert blocks are made of aluminium alloy and must be ordered separately from the heater units.
