HD22.2 Laboratory electrode holder with magnetic stirrer
HD22.3 Laboratory electrode holder
HD22.2
The HD22.2 is a laboratory electrode holder with an ultra slim magnetic stirrer. The height
adjustable electrode holder supports two standard
∅
12 mm electrodes. The stirring is performed
by a small magnetic bar (not supplied) immersed in the liquid: The motion is generated by a
rotary magnetic field controlled by microprocessor. There are no mechanically moving parts,
therefore no maintenance is required.
The rotational speed can constantly be adjusted from 15 to 1500 rpm.
The HD22.2 has a modern and functional design. It is made of materials that resist to most
chemical products: during use, control its compatibility.
Operation
Insert the magnetic bar in the liquid container to be stirred.
Power the stirrer by directly connecting the SWD10 power supply 12Vdc output (optional).
Turn the instrument on with the
key.
Set the rotational speed to the minimum by holding the
key, until the LED located
between the
and
keys stops blinking.
Now put the liquid container, at the center of the base.
Set the desired rotational speed by pressing the
and
keys; during adjustment the
LED located between the two keys is blinking.
The
key allows to invert the magnetic bar rotation. The lit LED between the
and
keys, indicates that the inversion function is on; the rotation direction is automatically inverted
every 30 seconds
.
The set speed and rotation direction remain in the memory also when the instrument is
off. Upon power on, the rotation will progressively go back to the previously set speed.
Note: If a non circular rotational motion begins, due to irregularities in the bottom of the container
or the magnetic bar, use the
and
keys to restore a circular motion.
The electrode holder height can be adjusted. To set the desired height, press the button and slide
the electrode holder along the staff.
HD22.3
The HD22.3 is a laboratory staff and electrode holder. Its height and depth can be adjusted. It
can hold up to 5 standard
∅
12 mm electrodes. The solid, fire-coated metal base, ensures
stability even with 5 electrodes. The staff is fitted with hooks for cables and electrodes.
