Why are my Genrui Laboratory Equipment test results unstable?
- M
  Michelle GreenAug 5, 2025
  Unstable test results in your Genrui Laboratory Equipment may occur due to several reasons: * Absorbance wasn't tested during startup – test absorbance during system maintenance. * The reagent is ineffective – exchange it for effective reagents. * The aspiration volume is insufficient – adjust the aspiration volume to be at least 600 μL. * The standard wasn't tested – measure the blank and standard again. * The wavelength is unavailable – use another wavelength to measure again. * Air is aspirated carelessly during operation – operate carefully according to the related requirements.

What to do if my Genrui WP21B Laboratory Equipment printer won't print?
- T
  Tasha HarrisAug 10, 2025
  If the printer on your Genrui Laboratory Equipment isn't printing, consider these possible causes and solutions: 1. The printing paper is unavailable – replace it with new printing paper. 2. The printing paper is seized up after tearing – adjust the location of the printing paper. 3. The heat-sensitive printing paper is inserted reversely – reinsert the printing paper correctly. 4. The printer temperature is too high – print again after the printer cools down.

What to do if my Genrui WP21B Laboratory Equipment is not aspirating?
- A
  Amy WangAug 19, 2025
  If your Genrui Laboratory Equipment is not aspirating, consider the following: * The aspiration pump does not rotate because the tightening screw at the pump head is loose. Solution: Tighten the screw. * The pump tube is loose. Solution: Cut out a small part at the connection of the pump tube. * The aspiration volume is zero. Solution: Reset the correct aspiration volume. * The pump tube is broken. Solution: Replace with a new pump tube.

Why did my Genrui WP21B fail to test the absorbance?
- T
  Tyler ShawAug 26, 2025
  A failure to test the absorbance on your Genrui Laboratory Equipment can happen because: * If the absorbance testing at a specific wavelength fails, but the testing at other wavelengths are normal, it may be due to distilled water not being used. Try testing again with clean and fresh distilled water. * Air bubbles in the cuvette, a dirty cuvette, or a faulty light-source lamp. Remove any air bubbles from the cuvette, wash the cuvette with a cleaning solution, or replace the light-source lamp.

How to fix a blurred or dark screen on Genrui WP21B Laboratory Equipment?
- A
  amanda02Aug 30, 2025
  If the screen on your Genrui Laboratory Equipment appears blurred or too dark, it may be because the display contrast of the LCD changes with the environment. To resolve this, adjust the contrast regulator inside the instrument.
