Fast, compact and "Class S" steam sterilisation

MELAG offers practices an economical alternative to the Vacuklav-series with its Euroklav 29 VS+, which, due to the instruments and the type of wrapping used, require no "Class B" steam steriliser. The Euroklav 29 VS+ features four "Class S" programs for sterilisation of wrapped, simple hollow instruments (e.g. scissors, needle holders, clamps etc.) and textiles, even if these are packed. Equipped with a powerful and efficient vacuum pump, a simple pre-vacuum occurs before sterilisation in order to remove air safely from the wrapping and from the interior of the instruments.

Control and monitoring of pressure and temperature parameters necessary for safe sterilization take place by means of sensors and an innovative micro-processing control unit. The innovative electronic design permits versatility in documentation, digitally through the network and MELAtrace or through the compact flash card as well as with the known MELAprint 42 log printer.

  • Class S autoclave
  • Powerful, efficient and simple pre-sterilisation vacuum pump
  • Four "Class S" programmes for sterilisation of wrapped instruments
  • 25 minute Quick Programme for unwrapped instruments
  • Integrated clean and waste water tanks
  • Control and monitoring of pressure and temperature parameters by means of sensors and an innovative micro-processing control unit

Too large feed water consumption

The feed water consumption is dependent upon the programme and the loading of the autoclave.

  Action

Check the correct set-up of the autoclave.

The floor of the vessel must be free. Where applicable, remove fallen instruments, filter paper, etc.

Bad drying results

Apart from a proper device function, the drying process depends decisively on the correct setting up and loading of the autoclave.

  Action

Check the correct set-up of the autoclave.

The floor of the vessel must be free. Where applicable, remove fallen instruments, filter paper, etc.

The tank filter is clogged. If necessary, check and clean it.

Pay attention to the correct loading of the autoclave (see page 20 of the Euroklav 29 VS User Manual, Load the autoclave).

Do not overload the autoclave. Make sure that textiles have no direct contact with the chamber wall and floor.

Activate the pre-heating (see page 23 of the Euroklav 29 VS User Manual, Select automatic preheating).

Employ the function Additional Drying (see page 24 of the Euroklav 29 VS User Manual, Additional Drying).

How often should you perform the helix test?

Once a day.

How often should you perform the ACT?

Once a day.

How often should you perform the vacuum test?

Once per week on a cold, empty chamber.

Do you need to drain the water from the autoclave at the end of each day?

Yes, no residual water must be left in the unit overnight. 

What instruments can you put through on the Quick S programme?

Hollow, solid and air retentive instruments can be put through on this cycle.

Can the autoclave be linked to a drain?

Yes, this requires the purchase of a double chamber syphon and can be fitted by a Henry Schein Dental engineer. 

How often should you download the data logger?

This is down to the practice requirements, but typically many practices will download once per week. 

My autoclave has a data logger attached; do I still need to carry out the TST test?

Consult the manufacturer of your autoclave as they will inform you if this is required. HTM 01-05 states that this should still be completed. If you obtain no advice from the manufacturer then follow the HTM 01-05 guidance.

Maintenance

  • Have maintenance carried out only by trained engineers.
  • Comply with the predetermined maintenance intervals.

Malfunctions at the autoclave can occur on continuation of operation despite the servicing message

For retention of value and functional reliability

Regular maintenance is indispensable for the retention of value and the reliable practice operation of the autoclave. During maintenance, all functional and safety-relevant components and electrical facilities are checked, and replaced if necessary. The maintenance is carried out according to the maintenance instructions which are relevant for this autoclave.

Maintenance intervals

Regularly allow for maintenance after each 1000 programme cycles or two years.


Cleaning

Examine the chamber including door seal and chamber sealing surface and the mounting for loading (page 20 of the Euroklav 29 VS user manual, Load the Autoclave) once weekly for contaminants, deposits or damage.

If you discover any contaminations, draw the existing trays or cassettes and the associated mounting forwards out of the chamber. Clean the contaminated parts. 

Door Seal

The door seal must not be greased or oiled. It should be kept clean and dry. 

When cleaning the chamber, the loading mounting, the chamber sealing surface and the door seal, observe the following:  

  • Switch the autoclave off before cleaning and pull the power plug from the wall socket.
  • Make sure that the chamber is not hot.
  • Use a soft and lint-free cloth.
  • Use chlorine- and vinegar-free cleaning agents.
  • First drench the cloth with cleaning alcohol or methylated alcohol and try to wipe off the contamination.
  • In case of persistent soiling of the chamber, mounting or chamber sealing surface, use only a mild stainless steel cleaning agent with a pH value between 5 and 8.
  • Use neutral liquid cleaning agents to clean the door seal.
  • No cleaning agents may get into the piping system which exits the autoclave chamber.
  • Do not use any rough objects such as pot cleaners made of metal or steel brushes.

In case of non-observance the cleaned surface could become scratched or damaged and the sealing surfaces not tight. This would promote dirt deposits and corrosion in the sterilisation chamber.

Housing Parts

Clean the housing parts with neutral liquid cleaners or methylated alcohol. 

Internal storage tank for feed water

If you provide the feed water supply manually via the internal storage tank, check for soiling when you refill the feed water. If necessary, clean the tank with a cloth and fresh feed water before refilling.

Make sure to wipe up and remove any soiling or impurities from the tank with a cloth without leaving any residues. If dirt particles are only detached but not actually removed, they can get into the dirt particle filter integrated into the drain hose while emptying the waste water tank.

Non-observance could impair the service life of the dirt particle filter and make it necessary to exchange the filter at short notice. 

Clean the left side of the water storage tank (waste water) every two weeks.

The both chambers are emptied as follows:

  • Attach the drain hose on a quick-fitting connection (left of the waste water tank, to the right of the feed-water tank), until this perceptibly engages.
  • Drain off the water into a container with at least 5 litres holding capacity.
  • To remove the drain hose again, press the grey release knob at the quick-fitting connection. The hose detaches itself automatically from the connection.

Please observe the following when removing the quick-fitting connection:

  • When draining the storage chambers, stand to the side of the connection.
  • Be sure to hold the hose tight with the other hand while pressing on the grey release button of the quick-fitting connection in order to arrest the spring tension of the connection. Non-observance can lead to injuries.

Repeat the procedure for the other chamber if necessary. 

Operation with feed water circulatory system

If the autoclave is operated in the feed water circulatory system, the feed water must be changed every week.

Avoid formation of spots

Formation of spots due to improperly cleaned instruments

Only if you correctly clean the instruments before sterilisation can you avoid the detachment of residues resulting from loading or instrument preparation under steam pressure during the sterilisation. Detached dirt residues (e.g. residues of disinfectants) can clog the filter, nozzles and valves of the autoclave and deposit as stains, spots or discolorations on the instruments and in the chamber (see page 19 of the Euroklav 29 VS user manual, Prepare items to be sterilised). 

Formation of spots due to third-party rust

All steam-conducting parts of the autoclave are made of non-rusting materials. This excludes the formation of rust caused by the autoclave. Should rust stains occur, then you are dealing with third-party rust. If the instruments have been incorrectly prepared, rust can form even on stainless steel instruments of leading manufacturers. Often a single rust-producing instrument already suffices for third-party rust to form on the other instruments or in the autoclave. Remove third-party rust from the instruments with a chlorine-free stainless steel cleaning agent or send the damaged instruments to the manufacturer for reconditioning.

Formation of spots due to inadequate quality of the feed water

The extent of the formation of spots on the instruments also depends on the quality of the feed water employed for steam production. 

Use qualitatively high-grade feed water

Observe the following when using feed water for the steam sterilisation:

  • Use only demineralised or distilled water.

In case of non-observance, stains or damage on the instruments can arise and the functional readiness of the autoclave can be adversely affected. 

Feed water which you can inexpensively produce with the osmosis processes with MELAdem® 40 or with the ions exchanger MELAdem® 47 or by distillation with MELAdest® 65, satisfies the requirements on the feed water.


Exchange the door seal

Image

If the door seal shrinks or is wavy, it is necessary to exchange the door seal. 

The consequence can be poorly sealed areas which can lead to the leakage of steam or cause a too high leakage rate in the vacuum test.

Open the door of the autoclave and take the old door seal out. The door seal is only inserted in the groove of the door plate.

Set the new door seal in the groove in such a way, that the wider sealing surface shows toward the chamber side. 

Observe without fail the different widths of the sealing surface. Only with correct seating in the groove is a proper closing of the door guaranteed and the chamber tight.
