In simple terms, calibration is establishing, correcting, or marking the scales of (anything) in order to determine its quality (something, such as a thermometer tube): to establish the accurate correction factors by calculating the variation from a standard in order to standardize (anything, such as a piece of measurement equipment). On the other hand, different industries define it in different ways. In industry definition, calibration means the documented comparison of the measurement equipment against an already known traceable range value to ensure measurement accuracy and quality.
Autoclave Calibration means bringing the response of a sensor into a defined range of temperatures required for clean-up. The engineers do this by comparing the autoclave sensor’s response to a standard measurement. They set the standard measurement by calibrating, experimenting and validating the performance of that standard equipment. Our service engineers adhere to a national reference standard.
The best way of autoclave calibration
To calibrate an autoclave properly, use NIST-traceable standards like a dry block, oil bath, or temperature probe. Ensure the dry block/oil bath is at a constant temperature to control temperature within ±0.1°C. If the equipment is not NIST-traceable, use a temperature probe with minimum precision of ±0.1°C.
If the equipment mentioned above is unavailable, one can calibrate the autoclave’s temperature sensors using boiling water. A bath with a consistent temperature of 100°C (212°F), which is somewhat close to sterilizing temperature and one can create it using boiling water. However, boiling water won’t always reach 100°C/212°F if the facility isn’t exactly at sea level. To get the precise pressure in your region, check the atmospheric pressure or use an absolute pressure manometer. Then, using this steam table, determine the actual “pressure corrected” boiling temperature of the water. You will need to do a calibration if you submerge your sensor in boiling water and it isn’t within 1°C of the predicted temperature.
Autoclave Calibration Procedure
There are different ways for autoclave calibration. We tried to make you familiar with the simplest way:
- Note the (zero and gain) calibration data as-found for each sensor that you want to calibrate.
- Remove the calibration sensors from the sterilizer while exercising the necessary caution (turn off the steam and wait for the pressure to drop to zero! ), leaving the connections that connect the sensors to the control system in place.
- Set the gain to 1 and the zero to 0 accordingly.
- Next, you need to place the sensor in the dry block or oil bath if you’re using a NIST-traceable dry block or oil bath.
- You need to set the position in the middle of the dry block or oil bath, with the sensors as near to it as practicable if you are using a NIST-traceable temperature.
- Record the standard and transducer data while measuring at the chosen temperatures. At each temperature, you should give the measurement at least a minute to stabilize. Do not skip this phase.
- Perform a linear regression on the information gathered. With the data from the standard plotted on the y-axis and the data from the sensor plotted on the x-axis, this is simple to do in Microsoft Excel using the intercept() and slope() functions.
- Use the correl() function also to perform a correlation. You need to use at least 0.999999 (i.e., a very straight line).
- To input, the calibration, enter the zero and gain into the sterilizer controller.
- Use at least one point, such as the process temperature, to confirm the calibration. If there are many process temperatures, check at each one. Then you will have exact precision.
- Finally, Replace the sterilizer’s sensors.
Importance of Autoclave Calibration
When evaluating an autoclave’s performance in various situations, calibration or validation is crucial. You must make sure your autoclave is in good working order as you are going to use it in a laboratory to process medicinal materials or on a production floor to process huge parts like composites.
An autoclave is an actual way of cleaning and sterilization. Steam, pressure, and time are all combined in the autoclave process. Autoclaves’ high pressure and temperature destroy microorganisms and spores.
Calibration is essential for precision temperature instruments like autoclaves. Although you can use a variety of instruments for the autoclave calibration operation, the most crucial factor is that you need to make sure about the accuracy level of national requirements. With an autoclave calibration certificate, Standard Calibration Services offers you the best autoclave calibration services. We always ensure that your autoclave calibration is meeting the industry standard.
