Lab Filtration

Microlab® PES Membrane（Polyethersulfone）is made of a modified polyethersulfone polymer cast.The optimized asymmetric structure, enhanced hydrophilicity and high porosity provides extraordinary high flow rate and contaminants retention capacity. The product uniformity results in consistent filtration performance. Its high mechanical strength supports most kinds of assembling technologies.  It is designed to remove particulates during general filtration, and its low protein and drug binding characteristics make it ideally suited for life science application.

Microlab® Cellulose Nitrate membrane filters are indicated for many general laboratory applications where a membrane with a high non-specific adsorption is suitable. They are hydrophilic, have high flow rates thanks to their symmetric structure and are compatible with aqueous solutions (pH 4 to 8), hydrocarbons and several other organic solvents. The cellulose nitrate membranes are available in different pore sizes from 0.2 μm to 8 μm.

Microlab® Nylon membrane filter is a supported, naturally hydrophilic membrane designed to wet out evenly and retain its superior strength during use in general filtration or medical assays, eliminating the need for wetting agents that could be extracted when filtering aqueous solutions. Nylon membrane filters are flexible, durable and tear resistant, and can be autoclaved at 135º C.High-quality nylon membrane filters are suitable for filtering aqueous solutions and most organic solvents. Nylon membrane filters are suitable for a wide range of biological preparations and can be used where other membranes are unsuitable or difficult to use.

Microlab® Mesh Filter is made of PP or Nylon fiber, with large pore sizes than the Micro-filtraiton Membrane. Because of Good Chemical Compatibility, Mesh filters are ideal for removing and recovering different types of large suspended solids from the solutions.

Microlab® Nylon Mesh Filter is made by woven monofilament type PA6(1:1 Weaving Methods), characterized precise mesh opening, percent open area and mesh thickness, with a broad range of solvent. Nylon Mesh Filter with mesh openings ranging from 10 to 180µm, can be fully meet the most stringent requirements of our customers.

Microlab® Polypropylene (PP) Mesh Filters are ideally suited for general clarifying and prefiltration of solvents and contamination analysis. PP mesh filters are made of 100% virgin polypropylene. PP mesh filters also provide broad chemical compatibility.

Microlab nitrocellulose membrane is composed of high-quality 100% pure nitrocellulose membranes. The rolls, sheets, are available in 0.22μm and 0.45μm with high surface area and uniformity. The nitrocellulose membranes have high binding properties for Western blot, dot-blot assays, and other protein or nucleic acid methods. Special formats have been developed for stripping and/or reprobing purposes.

50mm Vent Filters are sterilizing filter for Venting and Liquid Solutions. It removes microorganisms, particles, precipitates, and undissolved powders larger than nominal pore size such as 0.22μm. The special construction allows minimal hold-up volume and particle shedding, making Vent Filters ideally suited for the critical needs of the pharmaceutical and biotechnology industries. 

Microlab Reusable Filter holders are design for Membrane Filters with diameter ranges from13mm to 300mm. Both Plastic filter holder and Stainless steel Filter are available. Variety connection design are suitable for laboratory and industrial filtration.

Microlab Quantitative filter paper is mainly used for quantitative chemical analysis of the gravimetric analysis of the pilot trial and relevant analysis experiment. The filter paper can be applied to scientific research, industry agriculture, health, tertiary institutions, teaching experiment, environmental protection test, etc. 

Microlab Qualitative Filter paper is applicable to pharmaceutical, chemical plants producing all kinds of pharmaceutical and solvent filtration. the qualitative filter paper is chiefly used for qualitative chemical analysis and relevant filter separation, as well as manufacturing test paper of relevant purity. The good characterization of folded filter paper compared to the same type of filter paper formation has the advantage of speeding up the flow rate and increasing the load power.

Qualitative filter paper is a kind of filter paper used in laboratory analysis and testing, usually used to separate solid particles or mixtures of sediments and liquids. It has different pore sizes and adsorption properties, and different specifications and materials can be selected according to needs. Qualitative filter paper is commonly used in laboratory applications such as general qualitative analysis, qualitative chemical analysis, and qualitative separation.
