SteriPS Filter Cartridges

Single-layer PES Membrane · Sterilizing Grade

Cobetter SteriPS^® Filter Cartridges are specially designed to provide superior flow rates at an economical cost. The construction features a high particle removal efficiency. Hydrophilic polyethersulfone membrane cartridges require no prewetting and ready to use. This assures a cost effective device while maintaining great performance in the beverage applications.

Features and Benefits

Low diffusion flow
Inherently hydrophilic PES membrane
High surface area design provides high flow rates and extended service life while aintaining high bacteria removal efficiency
Lower protein binding

Validation Guide

The comprehensive validation guide is available upon request.

Flow Rate Characteristics

Integrity Testing Parameters

Bubble Point		≥3.2bar in water @23°C
Diffusion Flow	Cobetter SPSH	≤25ml/min @2750mbar
	P Company	Supor EBV ≤23ml/min @2760mbar
		Supor UEAV ≤50ml/min @2760mbar
	M Company	≤30ml/min 2750mbar

Raliable Microbiological Control

The primary purpose of a membrane filter cartridge in beverage processing is to effectively
control spoilage microorganisms.

Typical Log Reduction Value(LRV)
	B.diminuta	Lactobaccilus Brevis	Sasharomyces Cerevisiae
0.1μm	>7/cm²	N/A	N/A
0.2μm	>7/cm²	N/A	N/A
0.45μm	N/A	>7/cm²	N/A
0.65μm	N/A	>4/cm²	>7/cm²
1.2μm	N/A	N/A	>7/cm²

Log Reduction Values are calculated using the following formula:

LRV = log₁₀( total number of organisms entering the filter total number of organisms entering the filter)

Integrity Testing Parameters

The Integrity test is a non-destructive test that can be performed
by the user to ensure the filter is installed correctly and ready for operation.

Bubble Point
0.1μm ≥0.38MPa	0.2μm ≥0.32MPa	0.45μm ≥0.2MPa

* 0.45μm (Diffusional Flow ≤25ml/min@1500mbar)
