How long can the Microplate Reade be directly related to the daily maintenance of the user? Some users reflect their own Microplate Reade used for 5 years did not have any problems, but some say it took less than a year to appear a fault, or even to replace the important parts. Here we need to know how to Microplate Reade maintenance skills.
Microplate Reade is an optical detection and analysis instrument, so the dust attached to the optical device not only affect the test results, but also cause damage to the instrument, the more sophisticated the more serious the instrument. I was in the customs of an instrument to do when the adjustment, because the instrument is very new, the cooling fan is not dust, that their equipment just bought soon, fill in a single time to know that people have been used for more than three years. The same equipment has just been a hospital for nearly a year, the instrument appeared fault, opened, the dust on the fan too much, the operation has been very difficult, optical components on the fine layer, really doubt their usual test results, And fiber aging, must be replaced.
1, the working environment
Microplate Reade is a sophisticated optical instrument, so a good working environment not only to ensure its accuracy and stability, but also to extend its service life. According to DINVDE0871 regulations, the instrument should be placed in a non-magnetic field and the interference voltage position. According to DIN 45635-19:
• The instrument should be placed in an environment of less than 40 decibels.
· To prevent the aging of optical components, should avoid direct sunlight.
· Operating temperature should be between 15 ℃ -40 ℃, the ambient humidity between 15% -85%.
• The operating voltage should remain stable.
· Operating environment Air cleaning, avoid water vapor, soot.
• Keep dry, clean, horizontal worktops, and enough operating space.
2, operational considerations
The function of the Microplate Reade is used to read the results of the enzyme-linked immunoassay kit, so to get accurate results, the use of the kit must be standardized. Many hospitals in the use of Microplate Reade before the results through visual inspection, the operation process arbitrarily larger, after the use of Microplate Reade if not correct the operating habits, will cause a greater error. In the operation of the Microplate Reade should pay attention to the following:
· Use the dosing device to add liquid, add liquid head can not mix.
Wash the plate to be clean. If conditions permit, use the washer to wash the plate and avoid cross contamination.
· In strict accordance with the instructions of the kit operation, the reaction time is accurate.
· Do not touch the target plate during the measurement process to prevent the operator's hand from being squeezed when the plate is transferred.
• Do not spill samples or reagents on the surface or inside of the instrument. Please wash your hands after the operation is complete.
• If the sample or reagent used is contaminated, toxic and biologically hazardous, try it exactly.
• Instructions for operating the kit to prevent damage to the operator.
• If the instrument is exposed to contaminating or contagious items, clean and disinfect.
• Do not turn off the power during measurement.
· For the deviation caused by the measurement results caused by the kit problem, the parameters should be modified according to the actual situation in order to achieve the best results.
Use a cover to cover the dust cover.
· Technical failure should promptly contact with the manufacturers, not unauthorized removal of Microplate Reade.
