Sample pretreatment

Cell culture dishes/bottles/plates are made of imported ultra-pure and high-permeability medical grade polystyrene as raw materials, and are made by injection molding or blow molding with advanced hot runner technology, and are treated with vacuum plasma technology for surface hydrophilicity. The product has a uniform hydrophilic surface, which can make cells grow rapidly on its surface during the cell culture process. It is widely used in the cultivation and separation of cells in pharmaceutical companies, biological companies, scientific research institutes and third-party testing institutions.

In the process of ion chromatography analysis, there are often impurity interferences in the sample. For example, organic matter will contaminate the packing of the ion chromatography column, reducing the separation ability of the column and service life of the column, and impurity ions will interfere with the separation of target ions.

BM Life Sciences, BM IC series ion chromatography sample pretreatment column, is developed based on the principle of solid phase extraction, using high-purity materials and utilizing reverse phase adsorption, adhering to the mechanism of ion exchange, it can effectively remove organic matter and impurity ion, which can avoid the contamination of ion chromatography columns by impurities and their impact on separation.

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's® 96-well removable microplates for nucleic acid isolation 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.

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.
