Product Description:
The optical fiber of the coagulation analyzer plays an important role in the process of coagulation testing.
The coagulation analyzer is a medical device used to detect the blood coagulation function. The optical fiber is mainly used in the optical detection system. When the blood sample undergoes a coagulation reaction during the testing process, there will be changes in some optical properties (such as light scattering, transmittance, etc.). The optical fiber can accurately conduct optical signals and transmit the optical changes at the detection site to the photodetector. In this way, the instrument can analyze parameters such as the time and state of blood coagulation according to the changes in the optical signals.
Like the optical fibers in other instruments, the optical fiber of the coagulation analyzer also needs appropriate maintenance, such as keeping the connectors of the optical fiber clean, preventing the optical fiber from being bent or damaged, ensuring that the optical signals can be transmitted accurately, and thus guaranteeing the accuracy of the coagulation test results.
Polymerase chain reaction (PCR) instruments used for optical detection, optical fibers play a crucial role.
Optical fibers are mainly used to connect the optical detection components of PCR instruments, such as fluorescence detection modules. During the PCR reaction process, as DNA amplification occurs, fluorescently labeled substances will emit light at specific wavelengths. Optical fibers can efficiently transmit these optical signals to the photodetectors.
Its advantages include:
- High efficiency of signal transmission: It can transmit fluorescence signals with low loss, ensuring that the detector receives signals with sufficient intensity to accurately monitor the situation of DNA amplification.
- Anti-interference ability: Due to its material and transmission principle, optical fibers can effectively avoid external electromagnetic interference, ensuring the purity of optical signals and thus providing accurate detection results.
The optical fiber of the capillary electrophoresis instrument Product Overview
The following are the methods for cleaning and maintaining the optical fiber of the capillary electrophoresis instrument.
Cleaning Methods
- Cleaning of Connectors:
- Firstly, turn off the power of the instrument to ensure the safety of operation. Use lint-free cotton swabs dipped in a small amount of anhydrous ethanol or special optical fiber cleaner to gently wipe the optical fiber connectors. Be careful and gentle during the wiping process to avoid damaging the connectors.
- When wiping, wipe from the center of the connector towards the outer circumference to prevent dust or impurities from being pushed to the center of the connector and affecting the transmission of optical signals.
- Cleaning of the Optical Fiber Surface:
- For light dust on the surface of the optical fiber, you can use a clean and dry compressed air canister to blow away the dust.
- If there is more dust or some stains, you can use a soft and clean non-woven fabric dipped in a small amount of appropriate cleaner to gently wipe along the direction of the optical fiber.
Maintenance Methods
- Proper Use and Placement:
- During the use process, avoid excessive bending or twisting of the optical fiber. Generally, there is a specified minimum bending radius for the optical fiber, and you should operate according to the requirements in the instrument manual.
- When the instrument is not in use, place the optical fiber properly. It is best to coil it on a special optical fiber storage device to avoid the optical fiber from being squeezed.
- Environmental Control:
- Keep the environment where the optical fiber is located clean and minimize dust and corrosive gases as much as possible. You can place the instrument in a clean laboratory or use an instrument cover.
- Pay attention to the temperature and humidity of the environment and avoid drastic changes in temperature and humidity to prevent the optical fiber from being damaged due to thermal expansion and contraction or moisture absorption.
- Regular Inspection:
- Regularly check whether the optical fiber connectors are loose. If they are loose, tighten them in time.
- Check whether there are scratches, abrasions and other situations on the surface of the optical fiber. If any problems are found, evaluate the impact on performance and replace it if necessary.
