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. The unit can be used for incubation, boiling, inactivation, wet ashing, sample concentration, enzyme analysis and many other clinical and industrial purposes.
SPECIFICATION THE DB-2D DRI-BLOCK® This unit has a recessed chamber which can hold one or two inter-changeable insert blocks which accept test tubes or other sample containers. The temperature is set by 3 front panel buttons under the digital display. The DB-2D is supplied with an extraction tool for removing the blocks from the unit and two plastic half blocks for reducing heat losses when only one aluminium block is used.
THE DB-3D DRI-BLOCK® This unit has a recessed chamber which can hold up to three inter-changeable insert blocks which accept test tubes or other sample containers. The temperature is set by 3 front panel buttons with digital display. The DB-3D is supplied with an extraction tool for removing the blocks from the unit.
THE DB-2TC DRI-BLOCK® The unit has a recessed chamber which can hold up to two interchangeable insert blocks which accept test tubes or other sample containers. The temperature is set by 3 front panel buttons with digital display. The DB-TC is supplied with an extraction tool for removing the insert blocks from the unit.
WORKING ENVIRONMENT (ALL UNITS) The Dri-Block® units are designed to work safely under the following conditions: Ambient temperature 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. The specification will be closely held if the ambient temperature is in the range 10°C to 30°C.
OPERATION INSTALLATION 1. Select the insert aluminium alloy block(s) appropriate for the application. A list of available blocks is given on page 28 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. Place the insert blocks onto the hotplate in the well of the unit and place the tubes containing the sample liquid in the blocks. 3.
SETTING THE OVERTEMPERATURE CUT-OUT DB-2D Since there is no user-adjustable cut-out, 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-3D 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.
It will display this for 1 second, then the actual temperature of the plate will be indicated. THE FRONT PANEL CONTROLS The front panel controls consist of three buttons for controlling the display, a four digit LED display and three indicators. The “set” temperature Button 37.0 set The “set” temperature button displays the set temperature when pressed. The UP ARROW Button 91.8 set When the “set” temperature button is held down and the UP ARROW button is pressed, the set temperature is increased.
Power Indicator 20.0 set The top indicator shows that there is power to the unit. Heater Indicator 75.3 set The next indicator shows when the heater is heating the unit. When the temperature is being set, and the new set temperature is higher than the temperature already in the unit, the heater indicator will be lit up as the unit tries to follow the set temperature. If the light is on continuously the heater is getting constant power. The only exception is described under over-temperature indicator.
SETTING THE OPERATING TEMPERATURE 1. To display the set temperature on the digital display, press and hold the set temperature button. To adjust the set temperature, press the set temperature button and hold it while pressing the up or down buttons. When the set temperature button is released, the measured temperature is displayed (in degrees Celsius). 2. The heater (and heater indicator) comes on if the set temperature is higher than the current block temperature. 3.
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 heating unit. They will still have to be handled with care. 2. If you need to remove an insert block while it is hot, screw the extractor tool into the thermometer hole and lift the block out vertically.
ADDITIONAL INFORMATION ACCESSORIES Insert blocks are made of aluminium alloy and must be ordered separately from the heater units. The following blocks are available from Techne: Part Tube Size Number of Holes Size F3501 F3502 F3503 F3504 F3505 F3506 F3507 F3508 F3509 F3510 F4460 F4461 F4462 F4463 F4464 F4465 F4466 F4470 F4471 Plain block 6mm 10mm 12mm 13mm 15mm 16mm 19mm 25mm 10mm cuvettes Plain block 9mm/7mm 24mm 26mm 1.5ml Eppendorf 0.5ml Plastic half block 2 ml Eppendorf 0.
CALIBRATION Remember that if you change the calibration from that set at the factory you may change the calibration at all temperatures. You may get different calibration with different blocks. Make sure that you have good thermal contact between the blocks and the heater plate in the DriBlock®. In order to ensure that the calibration you are setting is correct, you will need to use an independently calibrated probe or thermometer.
1. Begin with items that are cool. 2. The blocks should be pushed firmly to the right hand side of the recess with no air gap between blocks. The right hand block will be used as the calibration block. 3. Switch on the unit and set the temperature display to 30°C. 4. Press all three buttons together and hold for 5 seconds until the amber “heat” light stops flashing and remains permanently on. 5. Self-calibration will now begin and the unit will begin to heat. 6.
