Internal observation

Dialysis Paper

The average pore size of 10 pieces of paper should be ≤35μm, and any piece of paper should not be ≥50μm. The paper has a certain resistance to water, the penetration time should be ≥20 s, and the internal tear resistance of the paper should be ≥550mN.

The bursting strength of the paper≥200kPa, soaked for 10 min, the wet bursting strength of the paper should be ≥35kPa.

Plastic film

The plastic film of the sterilization bag should be composed of 2 or more layers. The plastic bonding layer does not separate or whiten. Neither the plastic film nor the bonding area should release harmful substances known to cause health hazards. Not only should the plastic film of the sterilization bag be free of pinholes, when tested with normal or corrected vision under emitted light, but also the plastic film should be free of foreign substances and/or defects that will affect the performance requirements. The plastic film should be heat-sealed with the paper under the conditions specified by the manufacturer.

And paper should be heat sealed

The entire heat-sealing width ≥6mm, the plastic film burst point should be ≥20N/ 15mm width, the strength of the heat-sealing point before and after sterilization should be ≥115N/ 15mm width (dry sample) and ≥112N/ 15mm;

Width (wet sample) The range of the chemical indicator is ≥100mm2 and should not be affected by the sealing process.
