Grid film is the core consumable of microscopic counting method

Grid film is the core consumable of microscopic counting method, with the core function of accurately intercepting insoluble particles and assisting microscopic observation counting to ensure accurate and reliable test results.

Core use:

1. Particle interception: The grid membrane has a specific pore size specification and can selectively intercept insoluble particles of the target particle size (such as ≥ 10 μ m, ≥ 25 μ m) in the sample, preventing particle loss with the liquid and providing a basis for counting.

2. Auxiliary counting: The grid on the membrane surface can serve as an observation ruler, helping to distinguish individual particles, avoid repeated counting or omissions, and reduce background interference, making particles easier to identify under a microscope.

3. Ensure repeatability: A uniform specification of grid film can ensure consistent testing conditions for different batches and samples, making the counting results comparable and meeting the standardization requirements of experimental methods.
