Before long, performing that weekly spore test on the autoclave becomes just another task you check off of your weekly Things-To-Do list. Until, that is, you get that realize that says you failed. Then, it becomes 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 look for if yourTuttnauer autoclaves fails the spore test.
Not level: It’s among those things that’s easy to over look but when someone jarred your autoclave or it was recently moved to a new location it could be that it’s no level. The equipment has to be perfectly level in order to force steam downward at the proper angle.
Broken or dirty gasket: Check the gasket surrounding the door to the Temperature Humidity Test Chamber. It may be dirty or get some mineral deposits onto it which can be preventing it from creating an air-tight seal. If that’s the case, make reference to the manufacturer’s cleaning instructions. It may additionally be cracked or damaged in some manner and it’s super easy to replace.
Clogged or broken air jet valve: This valve allows steam to get released from your chamber. The pressure within the chamber circulates the steam and forces it from the air jet valve. This makes sure that the steam in the chamber remains in a constant temperature and pressure. If the valve is clogged or broken then that cooler steam remains in the chamber and results in cool air pockets. To clear the jet valve, simply pump the clean out wire back and forth 10 times.
Mineral deposits: Mineral deposits on the inside the chamber can prevent or inhibit steam circulation which can cause cold spots within the High Low Temperature Test Chamber. Clean the within the chamber regularly following the manufacturer’s directions. Never make use of an abrasive cleaner on the inside of the chamber.
Faulty heating element: Just because it looks like the heating element is working doesn’t mean it’s in working order. 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 measure the resistance. To find the proper range, speak to your owner’s manual.
Faulty timer: First, make sure you’re allowing proper warm-up time. When beginning from a cold autoclave you’ll need yet another 10 mins for that cycle. Obviously, the best way to test your timer is with an end watch.
Faulty temperature sensor: The IPX3 IPX4 Test Chamber, or thermistor, controls the heating elements and tells them when you ought to turn off and on. When the sensor is defective in that case 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 super easy to change this part yourself.
In many states, even one failed spore test is cause for alarm. You’ll immediately have to submit another test sample and wait another week for that results. By that time, you might be in big trouble. As soon as you observe that first failed test you have to determine what’s causing the problem.
And don’t panic should you fail a spore test. More often than not, it’s very easy to find and repair any issue you might have together with your Tuttnauer autoclave, while not having to send it out for expensive repairs.
