The Whatman 25 mm GD/X Syringe Filters are designed to enable the filtration of viscous, hard-to-filter samples greater than 10 mL. They are available in a wide variety of filter choices with a polypropylene housing. Each unit contains a prefiltration stack of Whatman Multigrade GMF 150 (10 & 1 μm) and GF/F.

To perform this procedure, the syringe filter is attached to a regulated, pressurized source of test fluid and the flow rate is determined from the volume of fluid processed in a specific time interval. Mass Spectrometry The Acrodisc MS syringe filter is eluted with 50:50 acetonitrile and water and analysed by mass spectrometry.

Disposable, multipurpose in-line filters are designed for the purpose of small-volume venting of solvents and for gas filtration. PTFE membrane and polypropylene housing have broad chemical compatibility. In-line filters can be used to help protect against bloodborne pathogens. They are useful for benchtop fermentors, in-line gas filtration for

Syringe filters, analytical filtration Print Share Syringe filters, analytical filtration Supplier: VWR, part of Avantor Ratings: (No Reviews) Available with either PP, PTFE or nylon membrane. Membranes are available in either 0,2 or 0,45 µm pore size, with the choice often made on analytical column packing size.

The H-PTFE membrane exhibits low protein binding and can be used for both aqueous and aggressive organic solvents. Suitable for sample preparation for high performance and ultra-high performance liquid chromatography (HPLC and uHPLC) Used with both aqueous solvents and aggressive organic solvents. Choice of 13 or 25 mm syringe filter diameter to suit sample volume.

0.2 μm PTFE syringe filter (VWR Internationals) and 2 mL HPLC vials (29651-U Supelco, Merck) were used. When stirring, cylindrical PTFE stirring bars (15x6mm, oval rare earth, VWR) combined with a standard VWR hotplate were used. The PTFE beads (3 & 6 mm PTFE balls, BOLA) and glass beads (2 mm glasschrot, Assistent) were ordered through VWR. The

Syringeless Filters. Available in a variety of filter media, syringeless filters allow you to process sample loads in a fraction of the time, providing a quick, economical, and environmentally conservative way to filter samples prior to HPLC analysis. These are preassembled filtration devices specially used in HPLC for the purification and

Reinforcing ring provides greater strength to the housing to prevent leakage and bursting (30mm products pressure rated to 120 psi) Housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices Able to filter solutions at temperatures up to 100°C

Available with either PP, PTFE or nylon membrane. Membranes are available in either 0,2 or 0,45 µm pore size, with the choice often made on analytical column packing size. If the column packing size is larger than 3 μm then use 0,45 μm, and if 3 μm or smaller then use 0,2 μm.

The district of Nanshan was created when Shenzhen became one of China’s first special economic zones. This means that it had many new reforms for business and between 1979 and 2010. This helped increase development in Nanshan significantly, especially since there were more foreign businesses moving into the city at the time.

EZFlow® 13, 25, and 33 mm sample prep syringe filters are designed for organic solution samples. Sample prep syringe filters are used for clarification and particle removal from samples before instrumental analysis such as HPLC, IC, and GC. These syringe filters are available in a variety of filter membrane materials, in 0.2 or 0.45 µm pore sizes.
