The service life of a fiber microtome depends on several factors, such as the quality of the device, how it is used and how it is maintained. Typically, a high quality fiber microtome can last for several years or more.

The fiber microtome requires regular maintenance and calibration to ensure its operation and the accuracy of the measurement results. The exact frequency of maintenance and calibration should depend on the device model and usage conditions. Typically, after using the fiber microtome for a period of time, the following maintenance and calibration are required:

1. Clean the equipment regularly: Keeping the equipment clean can avoid the influence of impurities and dust on the slicing accuracy.

2. Adjust the cutting knife: Adjust the position of the cutting knife according to the actual needs to ensure that it is in proper contact with the sample at the right angle and strength.

3. Calibrate the measurement results: according to the needs of the standard test sample, calibrate the equipment to ensure the accuracy of the measurement results.

4. Replace cutting knives: Replace worn cutting knives in time to ensure cutting accuracy and safety.

5. Check the circuit and equipment connection: Periodically check the equipment circuit and connection to ensure the stability and reliability of the equipment.

In short, timely maintenance and calibration can improve the service life and measurement accuracy of fiber microtome equipment, reduce failures and errors, and ensure the reliability of fiber testing.
