The BM Life Sciences range of filtration devices is divided into complete disposable vacuum filtration units and individual bottle filters. Disposable Vacuum Filtration Unit is a complete filtration device that can be used directly and independently, combining disposable filtration funnel (filters with upper part of the bottle including cap, connecting shaft, filter membrane and step interface), receiving bottle; Filters with the top of the bottle that do not include the receiving bottle must be additionally equipped with receiving containers for use. Ready for use, irradiation sterilization, sterility, no DNA enzyme, no RNA enzyme, no pyrogen, filtrate can be stored directly in a suitable sterile receiving bottle. Suitable for laboratory sterilization of large quantities of body fluids or removal of impurities. 

Different working tank characteristics are available for different filtration volumes.
The bottom neck of the filter hopper connection shaft is a standard GL45 port, which can be universally applied to receiving containers with the GL45 interface.

Capacity: 250ml, 500ml, 1000ml
Membrane pore size: 0.10μm 0.22μm 0.45μm
Membrane Type: PES, PVDF, CA membrane, etc.

B&M's® 24-well nucleic acid isolation plates 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. 

Characteristics of B&M® blot membrane: Pore size and protein type 0.1 μm for proteins with a molecular weight less than 7 kDa 0.22 μm for proteins with a molecular weight less than 20 kDa 0.45 μm for proteins with a molecular weight greater than 20 kDa Basic principles of protein binding Electrostatic and hydrophobicity Applied transfer conditions and detection methods Chemiluminescence Fluorescence Detection Radiolabile probes Direct staining Enzyme-bound antibodies Advantages:
1. Low background, high sensitivity.
2. No pre-wetting with alcohol reagents
3. Unique structure and surface properties, creating excellent signal-to-noise ratio, natural fiber material, environmentally friendly, and can keep the binding protein active for a long time.

STR-39X Human Amplification Fluorescence Detection Kit (Direct Amplification): It uses six-color fluorescent labeling technology and multiple STR fluorescent compound amplification method to simultaneously detect the polymorphism of 39 autosomal loci, 1 DYS391 Y-chromosomal locus, 1 Amelogenin sex locus, and 1 Y-indel insertion-deletion fragment in human genomic DNA. It can simultaneously detect the polymorphism of 42 STR loci, including FTA card, blood card, or saliva map, and directly amplify them (without isolating and purifying the template), which has a better effect, and is suitable for the creation of the Ministry of Public Security DNA database, case detection, investigation, abduction, and DNA identification of kinship, which is an extension of the loci of existing kits on the market, and is widely recognized by domestic and foreign customers in practice Applying. The set is an extension of the existing kits on the market, and has been widely recognized by domestic and foreign customers in practical application.

B&M's® ultra-microcentrifugal filtration columns consist of an outer tube, an inner tube, a PTFE membrane and a pressure ring. PTFE (fine powder resin) swells to form a three-dimensional mesh structure known as PTFE, which creates billions of microscopic pores. The 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.
