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.

The units cover the temperature range from 25°C to 200°C using machined aluminium alloy blocks as the heat transfer medium: temperature control circuits are built into the unit. Independent indicator Iights indicate mains power, heater action and overtemperature cut­out. An ONIOFF switch is mounted an the rear panel, together with the mains connector and a double fuse holder.

The units are constructed in PPS plastic, which is strong yet lightweight and can resist sustained temperatures as high as 260°C. Even though the units heat up rapidly, highly efficient insulation ensures that cases remains cool enough to handle even at maximum operating temperatures.

Techne's Dri-Block® range has been designed to comply with all relevant RF (Radio Frequency) interference and electrical safety regulations.

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.

Electrical supply

Voltage                    Cycles                  Power

220V-240V              50Hz-60Hz           650W

100V                        50Hz-60Hz           650W

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-1 M. The specification will be closely held if the ambient temperature is in the range 10°C to 30°C. Outside this range the quoted figures may deteriorate but the unit will still work safely.

Radio frequency interference tested and passed to EN50081-1.

Immunity Tested and passed to EN50082-1
