Both nylon and GHP membrane filters include a glass fiber prefilter layer, as well as being HPLC certified for low UV-absorbing extractables. The regular glass fiber membrane has very low extractables. Pall Acrodisc Syringe Filters Glass Fiber polypropylene housing. Female Luer-lock inlet and male slip Luer outlet.
The 25 mm Acrodisc is recommended for sample volumes from 5 to 100 mL. The 13 mm size is recommended for samples under 10 mL in volume. The 4 mm size is for samples under 2 mL. PP housing with Luer fittings. GHP - hydrophilic PP membrane suitable for both aqueous and organic samples; GXF - multi-layered glass fiber prefilter
Our filtration membranes are available in laboratory device configurations that process volumes from < 5 mL to hundreds of liters. Selecting the most appropriate Effective Filtration Area (EFA) will maximize throughput and minimize filter changes. The greater the volume being filtered, the larger the filter diameter you should choose.
General description. Ideal for autosampler vials and NMR tubes. Eliminates loss of sample and time caused by filter outlet not fitting sample vial openings. Acrodiscs with minispike are available in a variety of membranes. All choices are incorporated into 13 mm PP housings with a female Luer inlet and a minispike outlet (2.5 mm O.D.).
"These syringe filters offer a choice of filter media: hydrophobic PTFE membrane for exceptional chemical and temperature compatibility -hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without prewetting -GHP (hydrophilic polypropylene) membrane for low protein binding -and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous

Pipet-Lite™ XLS+ manual 12-channel pipette, 0.5-10 μL, uses LTS™ LiteTouch™ tips. Consistent sample pickup. Accurate,precise, ergonomic, volume lock, rugged, durable (L12-10XLS+) Fatigue-free pipetting and total control. Effortless pipetting due to light weight, light plunger forces and lowest tip ejection.
Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including Filter Plates, Syringe Filters, Centrifugal Devices and Membrane Filter Discs. Essential for biomolecule purifications and separations filter plates are offered in different filtration media membrane to accommodate any array applications. With individual membranes
May 04, 2022 · Step-by-step Procedures. Collect the sample and make any necessary dilutions. Select the appropriate nutrient or culture medium. Dispense the broth into a sterile Petri dish, evenly saturating the absorbent pad. Flame the forceps, and remove the membrane from the sterile package. Place the membrane filter into the funnel assembly.
Professional ghp membrane sample volume less 10ul GH Polypro (GHP) Membrane Disc Filters – Separations All purpose, universal membrane with maximum chemical compatibility for both aqueous solutions and aggressive solvents.
Feb 05, 2019 · The final optimized protocol was tested to determine how increased sample volume affects nucleic acid recovery (Fig 3A, S2–S5 Appendices). As Fig 3B shows, increasing the volume 10-fold and 100-fold (from 250μl to 2.5ml and 25ml) improved actin Ct values by 2.5 and 5.2 Ct values, respectively.
Membrane filters serve as effective physical barriers that remove solids, viruses, bacteria, and other unwanted molecules. Specialized types are designed for softening, disinfecting, organic removal processing, and water desalination. The filters can be installed in compact, automated, or modular units. These strainers can be used as separators
Using a custom fabricated cellulose acetate membrane, Ryu et al. created a further type of coculture system where cells on either side of the membrane were in much closer contact through the membrane pores. 74 The porosity of the membrane was shown to be greater than 50%, while the membrane thickness was less than 500 nm for all the pore diameters fabricated (0.1-, 0.4-, and 0.9-µm).
