INTRODUCTION
Please read all the information in this manual before using the unit.
Techne Dri-Block
®
heaters provide a safe, dry, constant temperature source in the laboratory. The
units can be used for incubation, boiling, inactivation, wet ashing, sample concentration, enzyme
analysis and many other clinical and industrial purposes.
The units cover the temperature range from a5°C to 100°C or 200°C (depending on model)
using machined aluminium alloy blocks as the heat transfer medium. Independent indicator lights
indicate mains power, heater action and over-temperature cut-out. An ON/OFF switch is mounted on
the rear panel, together with the mains connector and a double fuse holder.
Temperature setting is via a simple push button display. Temperatures can be displayed in °C or °F.
Each unit also has a built-in count-down timer which can be set in 1 minute intervals to 99h 59m.
The units are constructed of painted aluminium alloy and polyphenylene sulphide (PPS) plastic,
which is strong yet lightweight and can resist sustained temperatures as high as 260°C. Even though
the units heat up rapidly, venting and highly efficient insulation ensure that the cases remain cool
enough to handle even at maximum operating temperatures.
Each unit is supplied with an extraction tool for easy removal of the insert blocks.
