that dissolves the residue, but does not harm the Teflon bearing and the steel.

For proper cleaning, the dispersing element must be disassembled.

Proper care and cleaning of the equipment will ensure a longer and better use of
the equipment.
Sterilization

Chemical processes: Germicidal solutions (formalin, phenol, alcohol etc) can
disinfect in most cases. However, residues of the genome must subsequently be
removed with sterilized water.

Sterilizing by humid heat: This means sterilizing with steam at a pressure bar of
2 above atmospheric and a temperature of 120°C

Sterilizing by hot air: Hot air sterilization is normally carried out at 160°C or
190°C
Corrosion

Stainless steel is not corrosion proof. Certain chemicals can seriously attack this
material.

All corrosive agents should only be in contact with the fine steel for a short
period of time. Make sure they do not dry out the material.

Ensure that the dispersing element is always cleaned properly after every use.

Neutralize with solutions and acids.

Protect all parts from aggressive agents.
Working with the D-160
The optimal immersion depth of the dispersing shaft is approximately
2/3 below the liquid surface and 1/3 above the bottom of the beaker.
Based on the dispersing shaft used the unit can be used for following volumes 0.1-50ml
with the 5mm shaft, which makes it ideal for small applications inside tubes etc., or for
volumes of 1-250ml with the 10mm shaft which makes it ideal for all other test tubes or
small vessels.
Working with Speed Control
The drive and control are in the same housing. Before using the unit, run a test without
the dispersing shaft by switching the ON button on the side of the drive. The speed is
selected by the control knob on the top of the drive. Approximate rpm of the drive is:
