Product Description
The D-500 Disperser is a high speed dispersing instrument. It is based on the
Rotor/Stator Technology. The shaft and rotor/stator can be disassembled for easy
cleaning. You will receive the dispersing tools completely assembled for immediate use
with your disperser. Should you dismantle these (e.g. for cleaning) please refer to page
6. This product is for laboratory use only and is used in chemical industry, cosmetic
industry, pharmaceutical industry, paint industry as well as in universities and a wide
range of medical laboratories. The unit is a high performance dispersing/homogenizing
unit and also can be used as a high speed mixing unit with certain dispersing shafts.
The drive unit can be used, based on the dispersing shaft used for volumes from 10ml
to 8,000ml. There is a wide range of dispersing shafts with diameters of 20mm, 30mm
and 40mm stator diameters. It is to be mounted on a stand and not used as a hand
held instrument.
Safety Instructions
•When using electrical equipment, basic safety
precautions are necessary to reduce the risk of fire, electric shock and personal
injury.
•Only use the instrument for its intended purpose.
•Ensure that the correct electric voltage of the instrument and the power supply
correspond correctly.
•Do not use this instrument in a hazardous area or manner. When handling
hazardous chemicals, use appropriate hand and eye protection.
•Do not immerse electrical equipment in water.
•The drive must not be used in highly combustible areas and operated with
easily inflammable liquids. It is recommended to run the units in fume hoods
during operation.
•To avoid electrical shock, do not open housing. Remove cord from the power
source when it is being checked or serviced. This instrument should only be
opened by a qualified service personnel only.
•The D-500 is designed for continuous operation, however normally the
ultimate fineness will be reached within a few minutes. Any further dispersing
will only introduce unnecessary heat into the medium.
•The D-500 must never run without liquid – the lower slide bearing is cooled and
lubricated by the liquid phase of the treated medium. Any dry running will
destroy the slide bearing!
•Ensure that the dispersing shafts are cleaned properly after every use. When
cleaning, remove the power cord from the power source.
•Never touch the spinning rotor, or shaft, or motor side coupling parts.

•It is recommended that the operator should be using hearing protection when
operating the unit at maximum speed.
•Do not operate after the equipment malfunctions or has been damaged in any
manner. Return unit to our service center for examination and repair.
•Switch off the unit before changing the dispersing element.
•Only suitable dispersing shafts from SCILOGEX may be used.
•Glass vessels must always be secured with a clamp to prevent them from
sliding.
•Use caution when adjusting the speed to avoid possible spraying of medium.
•The ventilation slots of the drive must not be obstructed.
•Never let the aggregate touch the bottom of the vessel.
Unpacking the Instrument
Please unpack the instrument carefully and inspect the unit, the tools and the stand for
damage. It is important that any damage during transport is noted at the time of
unpacking. In certain cases it may be necessary to follow up with the forwarder.
D-500: A typical package includes:
• D-500 drive
• One support rod for the drive
• One or more dispersing element according to your order
• One H stand with double rod, boss head and strap clamp
or
• A plate stand with boss head and strap clamp
• Operating instructions

Proper Use
The voltage on the name plate must match the main voltage. If it does not, do not
operate the instrument.
Screw the support rod into the flange of the drive and tighten it. Make sure that the
“nylon” washer is between the flange and the nut to avoid scratching and rubbing
marks on the flange.
Make sure that the unit is switched off when connecting or disconnecting the
dispersing shaft into the drive.
For correct use the D-500 drive must be secured to a stand with a boss head. We
recommend that for this purpose you only use the H-600 plate stand or the PT-plate
stands. For safety reasons the container should be fixed with a strap clamp (which is a
part of the H-600 stand).
Insert the dispersing element into the drive flange by pressing upwards and turning
clockwise until it locks into place. A click confirms the correct insertion. Once inserted
the dispersing element should not move any longer.
To remove the dispersing element from the flange, hold the dispersing element and
turn anticlockwise and gently remove the dispersing element downwards. The distance
between the bottom of the vessel and the shaft should not be less than 8mm.

Dispersing Aggregates
• Disassembly of the dispersing tool
1. Hold the dispersing tool with a cloth (to avoid cutting of your hand due to sharp
edges at the stator). At the same time turn the shaft tube clockwise. Screw the shaft
tube of the stator and pull it over the axle and put it aside.
2. Now hold the rotor with a cloth and turn the axle anticlockwise. Slowly screw the
axle from the rotor and put it aside.

3. Remove the PTFE bearing from the axle. After this disassembly you should have the
following five parts: shaft tube, axle, rotor, stator and PTFE bearing.
To assemble the dispersing tool please follow above 3 steps in reverse
order (3./2./1.)
When assembling the dispersing tool, always make sure that the PTFE
bearing is fixed correctly and cooled by the working medium.
Otherwise, it may cause serious defects to the whole dispersing tool. Examine the
PTFE bearings regularly. Treat the dispersing tools carefully as they are the hearts of
your dispersing unit. In
particular the axle reacts very sensitive to impacts.
Cleaning
• Immediately after finishing work with the apparatus, the dispersing element must be
cleaned so that substance residues do not stick to the threads.
• Small bacterial cultures can form in the small grooves, and this will create difficulties.
For this reason, and to clean the dispersing tool effectively, it should be run in a solvent
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 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 lye with solutions and acids.
• Protect all parts from aggressive agents.

Working with D-500
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. When inserting the dispersing
shaft slightly slanted (approximately at an angle 15 degrees), it improves the efficiency
of the disperser. The dispersing shaft should not be immersed more than 30mm below
the flange.
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 front of the drive. The speed is
selected by the control knob on the top of the drive. Approximate rpm of the drive is:
A= 10,000 rpm B= 12,000 rpm C= 15,000 rpm D= 18,000 rpm E= 22,000 rpm F= 25,000
rpm G= 30,000 rpm
For an emergency stop, press the large button on the drive.
For reaching the best effects, the rotor speed of D-500 should be adapted to the
dispersion problem.
IMPORTANT
The maximum rotor speed depends on the kind of sample and its viscosity. The
speed is reduced by its viscosity in order to protect the drive from overload. If the
viscosity is too high, the motor will stop automatically to prevent damage to the
equipment. The electronic control system prevents damage to the motor drive.

Overload Protection
When the motor overloads and the power supply cuts off, switch off the main switch to
O, disconnect the aggregate and re-start the instrument as fast as possible, without the
load in order to accelerate cooling by the built-in fan.
Maintenance of Motor
The motor does not need any maintenance and there are no parts inside which can be
repaired by the user. The only parts which are excluded from this are the carbon
brushes. Please contact or your authorized supplier for replacement and use original
spare parts only. The carbon brushes can be replaced after disconnecting the power
supply!
Stand
The D-500 homogenizer is normally delivered with either the H-600 stand or the PT 800
plate stand. It is always important to safely fix the unit even when not using the original
stand for it, as the center of gravity is relatively high.
Make sure that the motor drive is fixed safely and cannot move downwards at any time
as this may cause damage to the instrument, the user or the sample.
Assembly of H stand
This H stand consisting of a double rod, two boss heads, a safety ring and a strap clamp
to secure the vessel.
The unit comes semi-assembled as the two double rods are connected and the two
boss heads and the safety ring is fixed in place already.
Put together the foot of the stand as
following: put each of the two bolts into its
place in the middle foot piece and screw
the both side pieces together with the
provided larger screws and the allen key.

Assembly of the PT plate stand
This stand is delivered with a base plate and a rod which is either 600mm, 800mm or
1000mm long. Assembly is very easy as you only have to screw in the rod into the plate
stand and secure it with the counter nut. Attach necessary boss heads such to the rod.
Once this bottom “H” has been fixed, take the
double rod and insert into the middle piece of
the foot stand. Turn it around and fix it with
the other allen key using the smaller screws
for it. Turn it around and fix the drive with the
support rod at the upper boss head and the
strap clamp at the lower boss head.
