Laboratory Filters

Meissner laboratory filters are small-scale filtration devices designed for laboratory, research, and process development work. They are used for evaluation, sampling, filterability testing, validation studies, small-batch filtration, and other applications where accurate small-scale filtration is needed before larger-scale process implementation.

Meissner offers several laboratory filter formats, including 25 mm syringe filters, disc filters in multiple diameters, and a 47 mm disc filter holder. These options support a range of low-volume liquid and gas filtration needs in laboratory and R&D environments.

25 mm syringe filters are used for critical small-volume filtration, sample preparation, filterability studies, venting, and lab-scale process evaluation. They are commonly used with aqueous solutions, biological fluids, media, buffers, and other small-volume samples in research and development workflows.

Meissner disc filters are available in multiple standard diameters, including 13 mm, 25 mm, 47 mm, 90 mm, and 142 mm formats. They are offered in a range of absolute-rated pore sizes to support applications from fine clarification through sterile filtration studies, depending on the selected media and retention target.

The 47 mm disc filter holder is a reusable holder designed for use with 47 mm disc filters in laboratory filtration and testing applications. It provides secure support for the disc during filtration and is used when users need a durable holder for repeated bench-scale or pilot-scale filtration work.

Meissner laboratory filters are available with a broad range of membrane and depth media for liquid, gas, venting, clarification, and prefiltration applications. Available options include hydrophilic media for aqueous filtration, hydrophobic media for gas and vent filtration, and depth media for particulate reduction and upstream clarification.

Meissner laboratory filters are designed to support scale-up by allowing users to evaluate filtration performance at small scale before moving to larger capsule or production-scale formats. This helps process development teams generate useful filtration data early and transition more confidently into larger-scale applications.

Yes. Meissner laboratory filters are well suited for high-purity laboratory and biopharmaceutical process development work, including sample preparation, filterability testing, clarification, bioburden reduction, and sterile filtration studies where consistency and clean processing are important.

Yes. Meissner laboratory filters can be used in single-use and hybrid process development workflows, especially where small-volume testing, disposable fluid paths, or early-stage evaluation is needed. Their compact formats make them useful for flexible lab-scale integration.
