• Turn on the centrifuge (switch on the side of the centrifuge).
• Open the cover of the centrifuge by pressing the COVER key. Before installing the rotor, check that the rotating chamber is free from any contamination. If there is dust, glass splinters, liquid residues, etc., remove them.
• The rotor can fall if not handled properly, therefore it should always be handled and placed in the centrifuge using both hands.
• Place the rotor on the motor axis by sliding it onto the cone as far as it will go (keeping the coaxiality between the rotor and the motor axis).
• Screw the screw fixing the rotor into the motor axis (clockwise), and then tighten it firmly with the rotor key.
• Fill the rotor with containers / hangers / test tubes according to recommendations in section Filling the rotor.
• In order to replace the rotor, first remove the tubes and containers from it, unscrew the screw fixing the rotor with the enclosed rotor key, counterclockwise, then using both hands, grab the rotor on opposite sides and remove it from the motor axis.
• Install another rotor as described above instructions.

Filling tubes

****| Fill test tubes outside the centrifuge.

If the manufacturer of the test tube has not specified the maximum level, fill the test tubes so that the centrifuged substance does not run out of the vessel during centrifugation. To do this, use the formula below:

---|---

Filling the rotor

| CAUTION!

Angle rotors must be used with a suitable cover which must be screwed securely onto the rotor. The rotor and the cover are marked with the same catalog number (REF) to eliminate the risk of incorrect selection when you have several types of rotors.

---|---

| Check that the impeller is seated correctly and firmly bolted to the motor shaft.

Do not exceed the maximum rotor load (information is provided on the rotor).

MAX. 24×2,4g – means the possibility of placing 24 test tubes in the rotor, each weighing 2.4 g.

To ensure symmetrical loading, insert test tubes of the same type and weight in pairs into opposite openings of the rotor. If reduction inserts are used, they should also be placed in the holes opposite to each other in pairs of the same type.

Maintenance

Cleaning of the centrifuge

****|

• Pull the mains plug before cleaning.
• Before any cleaning or decontamination process other than that is recommended by the manufacturer, the user has to ask the manufacturer if the planned process does not damage the device
• For cleaning, water with soap or other water-soluble mild detergent shall be used.
• One should avoid corrosive and aggressive substances.
• It is prohibited to use alkaline solutions, inflammable solvents or agents containing abrasive particles.
• Do not lubricate the centrifuge motor shaft.
• The unused centrifuge should have cover opened.

Once a week
Using wiping cloth, remove condensate or residues of the products from the rotor chamber.

Once a month

• Check the condition of the rotor mounting screw thread. If damaged, it must be replaced.
• Check the centrifuging chamber whether it is damaged. In case of damage, it cannot be longer put into operation. Notify authorized service workshop.

---|---

Maintenance of centrifuge elements

|

• In order to increase the durability of threaded places, they should be lubricated with technical petroleum jelly.
• Make sure that the sealing rings (rubber) are covered with a thin layer of technical petroleum jelly in order to maintain tightness (catalog number 17201 – element of basic equipment).

---|---

Cleaning of the equipment

|

• In order to ensure safe operation, one shall carry out in regular way periodical maintenance of the accessories.
• Rotors, buckets, and round carriers have to withstand high stresses originating from the centrifugal force. Chemical reactions as well as corrosion (combination of variable pressure and chemical reactions) can cause destruction of metals. Hard to observe surface cracks increase gradually and weaken material without visible symptoms.
• In case of observation of surface damage, crevice, or other change, as well as the corrosion, the given part (rotor, bucket, etc.) shall be immediately replaced.
• The rotor, including the fixing screw, buckets and round carriers must be regularly cleaned to prevent corrosion.
• Cleaning of the accessories shall be carried out outside of the centrifuge once every week or still better after each use. For cleaning them one should use neutral agent of pH value 6÷8. It is forbidden to use alkaline agent of pH > 8. Then, those parts shall be dried using soft fabric or in the chamber drier at ca. 50°C.
• Angle rotor should be placed on a fabric with holes facing down, for effective drying.
• Do not use bleach on plastic parts of the rotor.
• In this way, the useful service life of the device is substantially increased and susceptibility to corrosion is diminished. Accurate maintenance increases the service life as well and protects against premature rotor failures.
• Do not use bleach on plastic parts of the rotor.
• According to laboratory standards, minimize the immersion time in each solution.
• Especially prone to the corrosion are parts made of aluminium.
• Corrosion and damages resulting from insufficient maintenance could not be subject of claims lodged against the manufacturer.
• The unused rotor should have the lid removed.

---|---

HS accessories maintenance (HU):

|

• Check the general condition of seals.
• Make sure that rubber O-rings are lightly coated with silicone grease. Use high vacuum grease, e.g., type „C” by LUBRINA.
• In order to maintain hermetic sealing, it is recommended to replace the sealing rings after each autoclaving.
• Store hermetically sealed rotors and buckets with the lids removed.

Autoclaving

• Rotors, buckets, and round carriers can be sterilized in autoclave with temperature 121°C during 20 min (215 kPa), unless otherwise specified in the OPTIONAL ACCESSORY.
• During sterilization (autoclaved) by means of steam one should consider temperature resistance of individual materials.
• Deformation of the accessories (carriers or lids made of plastic) may occur during autoclaving.
• Do not autoclave disposable materials (e.g., tubes, cyto-container).
• The life of the accessory depends on the frequency of autoclaving and use.
• Autoclaving reduces lifespan of plastic components. They should be replaced if any signs of damage are visible, including a change in colour or shape or when leakage etc.
• Pressure in closed containers can cause plastic deformation or explosion.
• Prior to autoclaving the rotors and accessories, thoroughly wash and rinse with distilled water.
• Never exceed the permissible autoclaving temperature and time.
• If you want to keep the hermetic seals, replace the sealing rings after each autoclave.
