Syringe Filters - Specification
Merlin Syringe Filters units are used for small volume filtration of liquids, gas and other material-specific applications. They are made of extractable free virgin polypropylene housings with female luer lock and male luer slip fittings. New sealing ring design make itself for high operating pressure and faster filtration. They are produced to exceptional quality standards and eliminate common problems such as leaks and filter ‘blow off’. Color ring help identify membrane type inside easily. These syringe filters are ideal for applications in pharmaceutical, environmental, biotechnology, food, beverage and agricultural testing laboratories.
Features
- Easy to identify- the color coded band on housing clearly indicates the membrane material
- Pressure rated - to 90psi for unsurpassed integrity
- Sealing ring - minimizes bursting and leakage
- Pore size of filter media are available from 0.22μm, 0.45μm
- Universal Luer lock/luer slip design for versatility and maximum operational safety
- Chemically resistant - polypropylene housing
- Maximum filtration area - ensure uniformity and speed due to sample distribution rings
- Low extractable levels - generate interference free date
- Unequivocal re-producibility across all filters and lots

- Nylon is a very pure hydrophilic membrane with very low levels of extractables - it is mechanically very strong and can be used in many different applications. The Nylon filter membrane undergoes extensive testing before it is encapsulated to ensure that the level of extractables is unsurpassed
- Polytetrafluoroethylene (PTFE) is chemically resistant to virtually all solvents and can be used for working with aggressive media such as Strong acids and bases. PTFE is hydrophobic and requires pre-wetting (normally by using a small amount of alcohol) before being used with aqueous samples. PTFE filters can also be used to prevent moisture passing through air vents.
- Hydrophilic Polytetrafluoroethylene (PTFE) is unsupported membrane that ideal for HPLC and mixtures of aqueous and organic solvents. Use with both aqueous and organic solvents, along with their mixtures.
- Polyvinylidene Difluoride (PVDF) is a broad purpose hydrophobic membrane that can be used in a variety of applications. It has high flow rates and is generally compatible with most common solvents. PVDF is a low protein binder.
- Hydrophilic Polyvinylidene Difluoride (PVDF) provides high flow rates & throughput, low extractables& broad chemical compatibility and bind far less protein than nylon, nitrocellulose or PTFE membranes.
- PES low affinity for proteins and extractable with substantially faster flow rates than PVDF, suitable for pre-filtration and filtration of buffers and culture media.
