Functions as a prefilter when used with GF/B microfiber filters. Whatman™ Binder-Free Glass Microfiber Prefilters, Grade GF/D provide efficient membrane protection, especially during liquid scintillation counting.
Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 47mm Nuclepore™ Polycarbonate Hydrophilic Membranes combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology, parasitology, and certain air and oceanography analyses.
Use for rapid purification of PCR products (>200 bp) from unincorporated primers (<32-mers) and nucleotides. GE Healthcare Life Sciences™ illustra™ MicroSpin™ S-400 HR Columns use spin-column chromatography for quick results.
Use for purification and isolation of monoclonal and polyclonal IgG from ascites, serum and cell culture supernatants. GE Healthcare Life Sciences™ HiTrap™ Protein A HP Prepacked Columns are specially designed, together with the medium to provide fast, simple and easy separations in a convenient format.
Use for the rapid purification of DNA >10 base pairs in length in a wide range of applications. GE Healthcare Life Sciences™ llustra™ MicroSpin™ G-25 Columns are ideal for desalting, buffer exchange, and removal of unincorporated nucleotides from end-labeled oligonucleotides.
Use for quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates or for quantitative air pollution analysis. Whatman™ Quantitative Filter Paper: Grade 41 Circles are commonly used in preparing samples for metal analysis after nitric acid digestion.
Minimizes adsorptive protein loss when filtering protein-containing solutions. Whatman™ GD/X Disposable PES Syringe Filters are suitable for preparing viscous, dense, or otherwise difficult-to-filter samples prior to a variety of analytical methods.
Designed for stability in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. Whatman™ Puradisc PES Syringe Filters: Nonsterile allow higher liquid flow than either PTFE or PVDF.
Use for Western blots, dot-blot assays, and other protein or nucleic acid methods. GE Healthcare Amersham™ Protran™ NC Nitrocellulose Membranes: Sheets offer excellent sensitivity, resolution, and low background.
Used in high-volume PM-10 sampling equipment. Whatman™ EPM 2000 Air Sampling Filters are manufactured from 100% pure borosilicate glass. They enable detailed chemical analysis of trace pollutants with minimal interference.
