Vial filters provide a quick and easy solution for sample preparation for HPLC and UHPLC filtration. With a 1/3 reduction in runtime compared to other methods, no need to purchase syringes, tubes and caps, significantly fewer consumables and fewer steps to reduce sample loss, the Vial Filter will provide you with an unparalleled experience and efficiency.

An ultrafiltration centrifuge tube is a centrifuge tube with a membrane at the bottom, which is a biological separation device in centrifugation based on the size or molecular weight of the molecules and particles in the sample (i.e., when rotating at high speed, larger molecules or particles are pushed to the outer edge of the tube and smaller molecules pass through the membrane). The product consists of 3 parts: cap, ultrafiltration insert and tube body, and is characterized by high separation efficiency, ease of use and high concentration ratio (80-100x), which makes it easy to concentrate and extract the target product from dilute and complex mixed samples. Ultrafiltration tubes are widely used for protein concentration and purification, sample preparation for proteomics and genomics research, isolation of small molecules such as drugs and metabolites from biological samples, and separation and concentration of proteins, enzymes and other food ingredients in the food industry, so they are also called protein ultrafiltration centrifuge tubes or ultrafiltration centrifuge tubes.

B&M® purification columns are packaged with fiberglass membranes, a technology based on the rapid extraction of nucleic acids by glass fiber extraction. The columns can be used to purify single- or double-stranded DNA or RNA in the presence of impurities such as salts, solvents, enzymes, or proteins. Nucleic acids are adsorbed on the glass fiber at a high concentration of salt, salt and impurities are removed at the washing stage; Pure DNA/RNA is washed off the membrane with water or TE buffer.

B&M's® nucleic acid purification columns are based on the classic silica gel membrane technology. Under conditions of high salt content and low pH, nucleic acids are adsorbed on the silica gel membrane, while impurities such as polysaccharides and proteins are not adsorbed. Further rinsing removes the remnants of impurities. Finally, pure nucleic acids are produced by elution with a slightly saline solution or pure water.

The B&M® Large Nucleic Acid Purification Columns are based on the classic silica gel membrane technology. Under conditions of high salt content and low pH, nucleic acids are adsorbed on the silica gel membrane, and impurities such as polysaccharides and proteins are not adsorbed. Further rinsing removes the remnants of impurities. Finally, pure nucleic acids are produced by elution with a slightly saline solution or pure water.

B&M® 96-well centrifugal filter plates are assembled from 96-well filter plates + PTFE membrane + UHMWPE 20um sieve plate + compression ring. PTFE (fine powder resin) swells into a three-dimensional mesh structure known as PTFE, which creates billions of microscopic pores. This structure takes advantage of PTFE's inherent hydrophobicity (waterproofing) and non-stick properties, which allows the removal of particles that have fallen on the surface of the membrane. PTFE membranes and laminates provide equipment manufacturers with permanent, temperature- and chemical-compatible protection against microorganisms and particulates. The optimal combination of airflow and inlet pressure can improve the efficiency of most equipment designs.

24/96/384 well nucleic acid extraction plate is an auxiliary material for high-performance nucleic acid extraction and separation, which is mainly used for primer desalination, enrichment, extraction and nucleic acid separation. It can conveniently and quickly process 24, 96, 384 biological samples as 24/96/384 biological samples for the purpose of separation, extraction, beneficiation, desalination, purification, recovery, and so on.

B&M® HLB is a solid phase extraction column based on N-vinylpyrrolidone and divinylbenzene. The combination of hydrophilic and hydrophobic groups on the surface results in balanced adsorption of a wide range of polar and non-polar compounds, and the adsorbent retains a high adsorption capacity even after equalization and draining. This means that very high sensitivity can be achieved with a simple method. The matrix is pure, stable in the pH range of 0-14, stable in a wide range of organic solvents, and has a high adsorption capacity (3-10 times higher than that of C18). It is mainly used for the extraction of complex biological samples (e.g., blood, plasma, acidic, neutral, or basic drugs in body fluids).

Equivalent to Waters Oasis HLB.

B&M® Tip C18 pipette tips contain a silica monolith bonded to C18 (octadecyl). Silica monolith has a continuous structure with through holes. By combining with C18, the B&M®Tip C18 allows proteins and peptides to be desalted and concentrated in reversed-phase mode by easy pipetting.

During ion chromatographic analysis, impurities are often present in the sample. 
For example, organic substances contaminate the packaging of an ion-chromatographic column, reduce the separation ability of the column
and column life, and impurity ions will interfere with the separation of target ions.

BM Life Sciences' B&M® IC Series ion chromatography sample pretreatment columns are designed based on the solid state principle.

Sieve plates are an important component of flash columns, holding the packing in place and controlling the flow rate.
