Introductory Remarks

Thank you for purchasing the portable rotor-stator homogenizer RSH-1. Please read the operating instructions in full before using the instrument and follow the safety instructions.
This homogenizer is a high-speed dispersing instrument based on rotor-stator technology. This product is for laboratory use only and is used mainly for life science applications. Based on the type of rotor-stator probe (dispersion head) used, the working volume range is from 0.1 ml to 250 ml. The 5 mm probe is designed for handling 0.1 ml to 50 ml volume samples and the 10 mm probe for 1 ml to 250 ml volume samples. The probe can be disassembled for easy cleaning.
Due to the high rotation speed of the rotor, the medium to be processed is automatically drawn axially into the probe and then forced radially through the slots. This produces an extremely strong shear force and provides optimal homogenization of the samples.
The device is designed for continuous operation, although most samples are processed within a few minutes. Please note that longer sample processing times will increase the temperature of the medium, and may be detrimental to the sample integrity, while only offering small improvements in the sample homogenization.

Safety Instructions

• Inspect the device and the probe. Do not use damaged components and contact the manufacturer for replacement parts.
• Set up the stand in a spacious area on an even, stable, clean, non-slip, dry, and fireproof surface.
• Ensure that the stand does not move.
• Maintain basic electrical safety precautions necessary to reduce the risk of fire, electric shock, and personal injury.
• Do not operate the instrument in explosive atmospheres, or with hazardous substances.
• Avoid use in a humid environment and avoid water splashing on to the motor housing.
• Ensure that the voltage listed on the name plate matches the supply voltage.
• There is hazard of electrostatic discharges between the medium and the homogenizer probe.
• When working with glass vessels, the probe must not come into contact with the glass.
• Assemble the probe as per the instructions and ensure it is tightened well before use.
• Never run probes dry, as the PTFE sleeve bearing may be damaged if the probes are not cooled by the medium.
• The ventilation slots of the drive unit must not be obstructed.
• When the instrument is running at high speed, the ventilation hole will generate airflow. Do not keep powder or other light items close to the ventilation holes, as they can be blown away by the airflow.
• Ensure that only trained staff work with the instrument.
• Please only use the probe provided by the manufacturer to ensure a safe operation.
• In the event of unusual, grinding, or loud noise from the device, immediately switch the instrument off. Replace the homogenizer probe. If there is no change in performance after replacement, contact customer support for troubleshooting, repair, or replacement.

Unpacking and Inspection

Please open the box carefully and inspect for damage. If you find any damage to the instrument, please notify the supplier or manufacturer immediately.

Rotor-Stator Probe Installation

Remarks: In Step 2 insert the rotor unit into the drive unit so that it is fully seated against the drive unit. Hand tight the locknut while holding the rotor unit in place.

Operating Instructions

1. Ensure that the voltage listed on the name plate matches the supply voltage.

2. Ensure that the rotor-stator probe is screwed tightly on before use to prevent separation at high speeds.

3.  Before switching on the instrument make sure that the probe is immersed at least 20 mm below the liquid level to prevent the medium from splashing out. Do not let the probe touch the bottom of the container. Maintain a gap of at least 10 mm from the bottom.
   Note: The optimal immersion depth of the rotor-stator probe is approximately 2/3 below the liquid surface and 1/3 above the bottom of the container.

4. Ensure that the device is set to the lowest speed setting before switching it on.

5. Gradually increase the speed to the desired level.

6. Reduce the speed if the speed is too high and medium splashes out of the vessel.

Assembly of the Clamp and Stand

1. Use the screws provided to secure the left and right stand supports onto the stand base.
2. Screw the Stand Rod onto the stand base.
3. As shown in the picture below, insert the Cross Clamp Block onto the Stand Rod and secure it in the desired position by tightening the screw near the Stand Rod. Also, insert the Clamp Rod into the Cross Clamp Block (as shown in the figure) and secure in the desired position by tightening the screw near the Clamp Rod.
4. Secure the Clamp onto the Clamp Rod using the screw provided in the kit.
5. Secure the rotor-stator homogenizer into the clamp and tighten it before use.

Technical Specifications

Cleaning and Maintenance

• Please use a wet cloth to wipe the instrument gently, do not use corrosive liquids or detergents for cleaning.
• Ensure that the rotor-stator probe is always cleaned properly after every use. For proper cleaning, the rotor-stator probe should be disassembled and thoroughly washed with a mild detergent.
• If your application does not require sterilization, you may perform a simple cleaning of the rotor-stator probe in an appropriate solvent between uses. For example, if you’re homogenizing multiple samples with the same or similar composition, you could simply use the same solvent to remove most of the residue between samples. This should be done as soon as possible after use to avoid materials drying onto the rotor-stator probe. You will not have to dismantle the unit for this type of cleaning.
• The probe is made of stainless steel, but some chemicals may still cause corrosion. So, while cleaning use a solvent that dissolves the residue (like alcohol, water, or a mild detergent), but does not harm the materials of construction.
• The drive unit is maintenance-free but not immune from wear. The carbon brushes of the motor wear down over time. Please contact your supplier for replacement parts and use only parts supplied by the manufacturer to maintain warranty support. Disconnect the power supply before replacing the carbon brushes. You should never attempt to replace the motor brushes if the homogenizers are still under warranty, as it would void the warranty. Contact the manufacturer for warranty support.

Sterilization of Rotor-Stator Probes

• Disinfectants: Disinfecting using germicidal solutions (like formalin, phenol, alcohol, etc.)
  • Residues of disinfectant must subsequently be removed with sterilized water, and then dried to avoid contaminating future samples and also prevent corrosion of probes.
  • Please ensure that all chemicals used are compatible with SS 316L and PTFE.
• If a more thorough sterilization is required, the rotor-stator probe can be autoclaved. Please note that the probes are to be cleaned before autoclaving to ensure all residue is removed from the parts. If not, autoclaving could simply bake the residue. Hot Air Sterilization (at 160 ºC) is also an alternative to autoclaving.
