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.
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
lights indicate mains power, heater action and overtemperature cut-
out. An ON/OFF switch is mounted on 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.
