Membrane filters

Recommended for filtration, sterilisation and clarifications of mobile phase in HPLC processes with aqueous, alkaline and organic samples

• Made entirely of polyamide, hydrophilic
• High non-specific adsorption, high mechanical stability
• Qualified for many solvents and alkaline solutions, pH range 3-14
• Maximum temperature 134 °C

Housing MBS. HY (hydrophobic PTFE), for Venting and Gas Filtration.

MF-Millipore™ Membranes have a biologically inert mixture of cellulose acetate and cellulose nitrate. The MF-Millipore™ filters without Triton® surfactant have a lower water extractable content compared to the standard MF-Millipore™ filters and contain a minimal amount of wetting agent.

Features & Benefits:

• Manifold filter for biological and environmental monitoring applications
• available in various pore sizes
• white or black coloured
• Freely selectable whether with or without grid surface
• Compatible with ethylene oxide, gamma irradiation and autoclave sterilization methods

Solutions of any macromolecules, simple and efficient, desalt and concentrate. Suitable for any centrifuge holding 1.5 ml tubes.

Features & Benefits:

• Even with diluted solutions the recovery is more than 95%.
• Reverse spin to maximize recovery even in the smallest sample
• Storage of filtrate or concentrated sample, very easy in standard microcentrifuge tubes
• concentration factor up to 100 x

Membrane filters Cyclopore™ polycarbonate are true pore size microporous membranes featuring the sharp cut-off and reproducible microfiltration characteristics of track-etched membrane filters.

• Low affinity for stains improves visibility under a microscope
• Low protein binding minimizes sample loss of proteinaceous samples
• Narrow pore size distribution and high pore density support rapid surface capture of analyte
• Negligible absorption and adsorption of filtrate; nonhygroscopic
• No particle shedding enables clean filtrate
• Biologically inert
• Filters are autoclavable for 30 min at 121 °C

Hydrophobic PTFE membrane for applications involving organic solvents and chemically aggressive solutions.

• Maximum operating pressure of 4.1 bar forward and 3.0 bar reverse
• 1 µm capsules incorporate a PP prefilter
• Autoclavable up to 132 °C maximum
• Connectors: stepped barb (SB) and female national pipe thread (FNPT)

Durapore® PVDF membranes offer high flow rates and throughput, low extraction, agents, and broad chemical compatibility.

Features & Benefits:

• Can be sterilized by ethylene oxide and gamma irridation
• Avialable in different pore size
• Very low protein binding to minimize interaction with your sample and maximize recovery

Polycap TC filtration capsules feature dual layer polyethersulfone (PES) membranes and provide efficient filtration for aqueous solutions.

• 100% integrity-tested during manufacturing
• Polypropylene housing thermally fused to eliminate surfactants and mold releasing agents that could affect analysis
• Manufactured according to ISO9001:2008 QMS standards
• Available in sterile versions with a filling bell option
• PES membranes protein adsorption characteristics: HAS 0.4 µg/cm²; Insulin 2.0 µg/cm²; gammaglobulin 1.5 µg/cm²
• Connectors: stepped barb (SB)

Fittings with integrated ferrule for SafetyCaps and SafetyWasteCaps.
Use the blind plugs to tighten connectors which are temporarily inactive or not in use.

Suitable for analytical and gravimetric analyses, as well as a pre-filter.

• Hydrophilic
• Air / Gas Filtration
• Liquid Filtration
• Non-sterile
