Introduction to the use of Aijiren syringe filters membrane

1. Before inhaling the sample, suck about 1ml of air into the syringe, so that the liquid residue can be minimized

2. Inhale the sample into the syringe, turn the syringe upside down and clear all residues on the top

3. Connect the needle filter to the syringe and tighten gently to ensure a good seal

4. Filter the sample in the syringe and inject it into the sample bottle, and then follow the steps to maximize the recovery rate

Remove the filter, draw air into the syringe, reconnect the filter head, and push out all residual samples.

Precautions for Needle Filter Membrane

Use syringes with a volume of less than 10ml with caution, because the pressure of such syringes is sufficient to burst the needle filter.

It is best to choose the filter membrane recommended in the operating procedures.
