The syringe filter is a fast, convenient, and reliable filter tool that is routinely used in laboratories. It has a beautiful appearance, light weight, and high cleanliness. It is mainly used for sample prefiltration, clarification and removal of particles, and sterilization and filtration of liquids and gases.
The syringe filter is suitable for the filtration of a small amount of samples in the laboratory. It has low adsorption of samples, thus ensuring the maximum recovery of small or high-value samples. The filter housing is made of polypropylene, welded by ultrasonic, and does not contain sticky Mixture, so it will not contaminate the sample.
The advantages of syringe filters:
1. The flow rate is faster
The larger filter surface area increases the flow rate and filtration capacity, and also makes the filtrate easier because it reduces the pressure required to empty the syringe.
2. Higher operating pressure
The syringe filter has a maximum housing pressure of 10.5 bar, which means you can filter faster than before.
3. Color code
The color outer ring on the shell clearly indicates the type of filter membrane inside.
4. Reliable performance
The manufacture of the syringe filter is carried out in a controlled environment and automatic process. During the assembly process, the operator's hands never touch the filter. The quality certificate included in each box describes the quality standards in detail.
The syringe filter adds a layer of pre-filter membrane before the ordinary filter membrane to protect the microporous membrane. The pre-filter membrane can remove particulate impurities while preventing sticky impurities from clogging the filter. The filter membrane is made of chemically inert materials, which is resistant to most solvents. The rigidity of the membrane and the structure of large specific surface area have the characteristics of small retention capacity and low resistance, so the syringe filter can maintain high throughput even when processing difficult-to-filter samples.
"Pall PALL Syringe Filter Evaluation Report"
Pall PALL syringe filter can provide a variety of filtration options such as gas, aqueous solution, and organic solvent. By optimizing the filtration membrane material, it can obtain higher filtration speed and filtration volume, and improve filtration efficiency.
1. Water solution syringe filter
Pall PALL water solution syringe filter adopts optimized low-protein bound polyethersulfone (PES) membrane, namely Supor membrane, which has the advantages of fast flow rate and large processing capacity during filtration and sterilization, and the overall filtration efficiency exceeds that of similar products. At the same time, Pall's PALL Supor membrane has low protein binding properties, which reduces sample loss. It is very suitable for the recovery of trace samples and precious samples, and is widely used in the fields of biochemistry, testing, and pharmaceuticals.
2. Aqueous/organic solvent syringe filter
Pall PALL aqueous solution/organic solvent syringe filter, the membrane material uses hydrophilic polypropylene membrane, namely GHP membrane, has hydrophilicity and chemical compatibility, can satisfy the filtration of aqueous solution and organic solvent at the same time, it is known as the "universal membrane". Pall PALL GHP membrane is a non-adsorbent membrane to avoid binding non-specific biomolecules during detection; GHP membrane does not dissolve in high performance liquid chromatography (HPLC) and will not contaminate samples; GHP membrane has extremely low self-fluorescence value and is used for fluorescence detection There will be no background noise. Therefore, Pall PALL aqueous/organic solvent syringe filters are widely used in HPLC sample preparation, lysis reactions, strong organic reagents, high-throughput screening, metabolic research, combinatorial chemical screening, and receptor: ligand screening.
3. Gas needle filter
Pall PALL gas syringe filter adopts hydrophobic polytetrafluoroethylene (PTFE) membrane, which can allow gas or air to pass through and retain moisture at the same time. It is routinely used in gas filtration. Pall PALL gas syringe filter can be sterilized by high temperature and high pressure, and used repeatedly; its effective filtering area is larger, the filtering speed is faster, and the filtering efficiency is much higher than that of similar products; it can provide inlet/outlet connections suitable for different instruments and equipment Device. It is widely used in ventilation of incubators and fermentation equipment, organic sample preparation, drug synthesis reactions, and molecular synthesis reactions.
