Before long, performing that weekly spore test on your autoclave becomes just another task you check off of your weekly Things-To-Do list. Until, which is, you get that observe that says you failed. Then, it might be a top priority to find out what’s wrong, why you failed the test. If you’re ruled out operator error, then it’s probably an equipment problem. Listed below are 7 problems you can try to find if yourTuttnauer autoclaves fails the spore test.
Not level: It’s among those things that’s simple to over look however, if someone jarred your autoclave or it was recently moved to an alternative location it could be that it’s no level. The machine must be perfectly level in order to force steam downward in the proper angle.
Broken or dirty gasket: Check the gasket surrounding the door towards the Temperature Humidity Test Chamber. It may be dirty or have some mineral deposits into it that are preventing it from creating an air-tight seal. If that’s the case, reference the manufacturer’s cleaning instructions. It may even be cracked or damaged in some way and it’s super easy to switch.
Clogged or broken air jet valve: This valve allows steam to get released from the chamber. The pressure within the chamber circulates the steam and forces it from the air jet valve. This makes sure that the steam inside the chamber remains at a constant temperature and pressure. If the valve is clogged or broken then that cooler steam remains in the chamber to result in cool air pockets. To clear the jet valve, simply pump the clean out wire back and forth ten times.
Mineral deposits: Mineral deposits on the inside of the chamber can prevent or inhibit steam circulation which can cause cold spots within the High Low Temperature Test Chamber. Clean the inside of the chamber regularly following the manufacturer’s directions. Never work with an abrasive cleaner on the inside of the chamber.
Faulty heating element: Just as it looks like the heating element is working doesn’t mean it’s functioning properly. There may become a short somewhere that’s preventing it from heating towards the proper temperature. To check, you’ll want to use a volt/ohm meter to look at the resistance. To get the proper range, talk to your owner’s manual.
Faulty timer: First, make sure you’re allowing proper warm-up time. When beginning with a cold autoclave you’ll need an extra 10 mins for your cycle. Obviously, the easiest method to test your timer is with a stop watch.
Faulty temperature sensor: The Water Spray Test Chamber, or thermistor, controls the heating elements and tells them when you ought to turn on / off. If the sensor is defective then your machine won’t reach the proper temperature. If you’ve tested the mvndkc and it’s within the proper range, then the problem is with the thermistor. Again, it’s quite simple to switch this part yourself.
In many states, even one failed spore test is cause of alarm. You’ll immediately need to submit another test sample and wait another week for that results. By that period, you could be in big trouble. As soon as you observe that first failed test you have to determine what’s creating the problem.
And don’t panic if you fail a spore test. Most of the time, it’s very readily available and repair any difficulty you might have together with your Tuttnauer autoclave, without needing to send it out for expensive repairs.
