The 'last line of defense' between sterile water filter laboratory and clinical water use

Bacterial Filter

The Last Line of Defense for Water

Removes pyrogens, nucleases, and bacteria

Guarding the final barrier for sterile water

In cell culture, PCR, and DNA sequencing, water is not a background—it is a reagent.

But many researchers have encountered situations like these:

The ultrapure water system shows acceptable resistivity, yet the cells are still contaminated.

PCR fails repeatedly, and no cause can be found even after changing water and reagents.

The rinse water for endoscopes fails testing, leading to deductions in infection control inspections...

The problem often lies not at the water production end, but between the outlet and the point of use.

The sterile water filter is the terminal barrier installed at this position.

Product Description

Sterile Water Filter Product Description

Shandong Kanghui Water Treatment Equipment Co., Ltd.

Kanghui Water Treatment's sterile water filter is made of double-layer 0.2-micron folded membrane. The pre-filter layer uses an asymmetric structured membrane, achieving a retention of >10⁷/cm² for Pseudomonas aeruginosa. It can quickly and conveniently provide sterile water for patients, medical staff, and instruments, reducing the risk of infection.

The product features a compact structure, easy installation, a long service life, and excellent performance.

Application Scope

Sterile Water Filter Application Scope

Suitable for biochemical analysis and research fields with extremely high sensitivity to bioactive impurities in ultrapure water, such as:

Research scenarios: Cell culture, molecular biology, DNA sequencing, PCR

Clinical scenarios: Pre-operative hand washing, medical instrument rinsing, patient wound irrigation, and rinse water for endoscopes after high-level disinfection.

Water production is just the beginning; safeguarding water is the key.

The sterile water filter guards the last centimeter at the water outlet.
