Sieve plates are an essential component of columns for solid-phase extraction, holding the packing material in place and controlling the flow rate.
B&M® SPE sieve plates are professionally optimized to control flow rate, purity, stability and solvent compatibility. We currently offer porous plastics, porous composites, functionalized porous media (e.g., laboratory cartridges, sieve plates, medical cartridges, industrial cartridges, water filtration cartridges, etc.). Development and production of bioactive porous media and other high-performance porous materials. As well as the use of self-developed high-standard equipment combined with professional technology to provide cost-effective OEM services for solid phase extraction (SPE columns).

Hydrophilic sieve plate: generally refers to the reaction between reactive functional groups attached to a solid-phase carrier (e.g., resin, etc.) and a reagent dissolved in an organic solvent. It is a hydrophobic material made of ultra-high molecular weight polyethylene (UHMW-PE) sintered by modifying the surface with a hydrophilic agent.
B&M® Hydrophilic Sieve Plates Hydrophilic UHWMPE production technology is applied; the hydrophilicity of the sieve plates for affine chromatography columns has been specially treated for wetting with aqueous solutions; This is very advantageous when filtering aqueous solutions.
In solid-phase peptide synthesis, the peptide chain is elongated on an insoluble polystyrene resin carrier. The C-terminal portion of the synthetic peptide is first reacted with chloromethylpolystyrene resin (ester resin) to form a benzyl ester, and then the amino acids protected at the amino terminal are added one by one in the order of the primary structure of the peptide chain to elongate the peptide chain. The solid-phase method is simpler and shorter than the liquid-phase method and can be automated. It is used in our pharmaceutical industry.

Hydrophobic sieve plates are a traditional type of sieve plate that is an essential component of SPE/Flash columns, holding the packing material in place and controlling the flow rate. SPE/Flash sieve plates are specifically optimized to control flow rate, purity, stability, and solvent compatibility.

B&M® pipette tip filter cartridges are made of ultra-high molecular weight polyethylene, which is hydrophobic, compact, durable, lightweight, can withstand high filtration pressure, non-toxic, odorless, has good corrosion resistance to acids and alkaline solvents, blocks aerosols, preventing liquids and liquid vapors from contaminating the inside of the pipette gun.

BM Syringe Type Empty Columns consist of an empty column, upper and lower sieve trays, which can be filled with SPE adsorbents, filter membranes, solid reagents, etc., according to the customer's request, to meet the flexible needs of the laboratory.
