Application

Where This Category Fits

Who It Is For

  • Pharmaceutical QC labs preparing assay and dissolution samples for HPLC and GC analysis
  • Environmental labs filtering water, soil, and air extracts before IC and ICP testing
  • Food and beverage labs clarifying samples with high sugar, fat, or protein content
  • Life-science labs processing cell culture supernatants and protein solutions
  • Lab distributors and OEM brands requiring a full range of membrane types from a single source

Problems It Solves

  • Unfiltered samples introduce particulates that clog chromatography columns and reduce column lifespan
  • Extractables from poorly sealed housings appear as baseline noise or ghost peaks in gradient HPLC runs
  • Inconsistent membrane chemistry across vendors leads to method transfer issues between labs
  • Lack of printed identification on housings causes incorrect membrane selection during high-throughput analysis
  • Filters fail under pressure when handling viscous or high-solids samples without proper pressure rating
Advantages

Why Buy This Range From Microlab

  • Nine membrane chemistries in 13 mm and 25 mm housings allow method flexibility without changing filter geometry
  • Injection-moulded sealing across the range eliminates solvent bonding and reduces extractables
  • Colour coding and printed part numbers on the housing enable quick identification at the bench
  • Sterile, vented, and non-vented options available alongside standard and reusable-holder configurations
  • OEM printing and private-label packing supported through the in-house OEM division
  • Sample clarification before HPLC and GC analysis to prevent column fouling
  • Filtration of aqueous and mixed solvent mobile phases for routine method use
  • Clarification of protein solutions and cell culture media in biotechnology workflows
  • Pre-filtration of environmental extracts to remove particulates before elemental analysis
  • Sterile filtration of small-volume buffers and reagents in laboratory preparation

FAQ

Frequently Asked Questions

Which membrane filter range should I start with?

Easyfil covers most routine sample preparation across nine membranes in 13 mm and 25 mm. Sterifil is for sterile filtration needs, and Vent Filter is designed for gas and venting applications.

What pore size do I need for HPLC?

0.45 micron is standard for protecting HPLC columns. Use 0.22 micron for UHPLC, sub-two-micron columns, or when finer particulates must be removed.

Do you supply membrane filters under our own brand?

Yes. The OEM division supports OEM plastic devices, contract manufacturing, membrane die-cutting, and packing, enabling private-label printing and packaging.

How are membrane filters packed?

Standard packing is 100 pieces per pack, with part numbers and membrane type printed on each housing for immediate identification.

Can I reuse a membrane filter?

Single-use filters should not be reused due to carry-over risk. Reusable filter holders are available for flat membrane discs and can be cleaned between uses.
