Before Picture
This is an example of the work we do. This is a Tuttnauer autoclave where you'll see before and after pictures of our service. Pictures speak for themselves.
Before Picture
Old worn out door gaskets can cause steam to leak and cause chamber to lose pressure. If you notice cracking, warping, or steam is seeping out from the door it is time to change the door gasket.
After Picture
New door gasket is installed to insure a tight seal once door is closed to keep steam escaping prematurely from the chamber.
Before Picture
Here is a chamber with build up of black residue that could result in premature failure of components or damage to delicate surgical instruments. Over time this residue or foreign matter can build up enough to clog the tubes which transport water from the reservoir which is needed to produce steam to sterilize surgical tools.
After Picture
We use a strong cleaning base solution to remove and scrub out the black residue to insure you have clean heating surfaces. The heat radiation processes need clean, uniform surfaces to insure a fully effective drying cycle.

After Picture

Before Picture
In the back of the chamber you have an exhaust port hole above that allows steam to escape during the exhaust cycle and a water port hole below that allows enough water to fill in chamber as needed for sterilization cycle. If you notice, something here is missing. There's nothing to prevent these port holes and tubing behind that from getting clogged up with foreign matter that could potentially damage the autoclave.
After Picture
We install what is called fill/vent mesh chamber filters that will help prevent premature build up of foreign matter in the tubes that can lead to disfunction of your autoclave.
Before Picture
This is a safety door switch. This switch prevents the autoclave heating element from heating or burning out while door is open in the sterilization position. Safety switch is exposed to steam that can damage the internal components of the switch and over time cause switch to stick in on or off position only. If it sticks in the on position, the heating element will remain on while the door is open during sterilization cycle position. If it sticks in off position, the autoclave will not power up. Should this happen, the door switch will have to be replaced. This is a common problem on Tuttnauer autoclaves without a rubber boot on safety door switch.
After Picture
We install rubber boot for door switch on Tuttnauer autoclaves as necessary to prevent damage to the internal components of the safety door switch.
Before Picture
This is an internal view of the reservior which holds distilled water. Water has been drained in order to remove the slime and sludge during the cleaning process.
After Picture
We help clean out any debris in reservior to prevent damage to the internal components and extend life of your autoclave
Before Picture
Over time your reservior can look like this without preventative maintenance.
After Picture
Keeping reservior clean can insure longer life of your autoclave.
Before Picture
Over so many repetitious sterilization cycles, trays eventually get gummed up with baked on residue of foreign matter that oxidizes to these surfaces.
After Picture
We help remove the baked-on residue and oxidation matter on tray holder and trays to insure a clean uniform surface for more efficient drying of packs or surgical tools.
Before Picture
We further inspect to make sure autoclave is heating properly and puts out recommended temperature according to manufacture specifications. Thermometer is used to confirm temperature and insures temperature gauge is working properly.
After Picture
We take the extra time needed to make sure the internal thermostat is calibrated properly to insure autoclave is putting out the desired heat necessary for sterilization and not overheating. Timer is also tested to insure optimal performance.

Autoclave Preventative Maintenance Details
Valley Microscope strongly recommends a professional cleaning overhaul on autoclave (sterilizer) equipment if the chamber contains build-up of rust, greenish or black residue that could result in premature failure of components or damage to delicate surgical instruments, and reservoir is dirty or built up with foreign matter that can clog up your tubes therefore reducing the life of your sterilizer. Processing sterile goods under these conditions can be at the least distasteful, but more importantly, can be less efficient than processing in a clean chamber. The heat radiation processes need clean, uniform surfaces to insure a fully effective drying cycle. Our preventative maintenance cleaning service will help reduce the frequency of equipment malfunction and the risk of accidental contamination of sterile items. Preventative maintenance includes cleaning chamber, reservoir, tray holder, and trays with a solution that is super effective and safe in dissolving the crud & removing the nasty residue from the stainless steel components. Furthermore, we clean reservoir and the plumbing tubes channeling into it by using another solution that will flush out the build up of gunk or other foreign matter. This cleaning solution is ran through a few sterilization cycles through the plumbing system to insure harmful deposits in the valves and tubes are removed, then we drain the solution and flush out the tubes with distilled water. We also test the temperature and timer to make sure they're operating at peak performance. We then strive to provide this service on-site in your lab and it generally takes about 3 hours to service an autoclave(sterilizer) if no known problems are discovered during our testing procedures and no repairs are needed.

Before we can perform a cleaning on a sterilizer we need to know the make, model #, and serial number of your autoclave, and if you're having any other issues with it so that we can obtain correct parts necessary to restore your autoclave in good working order. As the autoclave is being cleaned we inspect valves, filters, gaskets, and electronic components to insure reliable service. This scheduled cleaning and inspection will prolong the dependable life of your autoclave. Get a free estimate below based on your type of autoclave/sterilizer!
