solvent compatibility ghp syringe filter lower hold-up volume . Polypropylene housing with female Luer-Lock inlet and standard male slip Luer outlet connections. All membranes are HPLC certified for low levels of UV-absorbing extractables.

Chosen for combinations in which the polymer and solvent/solution may be compatible, depending on the conditions in which the filter or filtration device is used. We recommend that the user test for compatibility prior to use ND = No data presently available. No data is currently available in the literature regarding polymer-solvent compatibility.

Finally, consider the volume of your sample to identify the right lab filter for your needs. Sample volume <2 mL: 4 mm filter and <10 µL hold up volume Sample volume <10 mL: 13 mm minispike and <14 µL hold up volume Sample volume <10 mL: 13 mm male Luer and <30 µL hold up volume Sample volume <100 mL: 25 mm filter and <100 µL hold up volume

Depth filtration. In terms of particle retention, filters fall into two categories: surface filters and depth filters. Surface filters, generally referred to as membranes, trap particles exclusively on the top surface. These filters are well suited to samples with low particulate content. However, high particulate content tends to rapidly clog

May 20, 2019 · This will depend on the sample volume (Table 2). Larger filters will provide faster filtration with lower pressure (minimising the chance of bursting the membrane); however, the trade-off is that they have higher hold-up volumes, which could trap sample, resulting in greater sample loss and poor quantitation’s.

Feb 17, 2020 · Step 2: Attach a syringe filter to the Syringe. Open the syringe filter package so that you can later pick the filter up easily, especially for individually packed sterile syringe filters. a. For sample volume < 10 mL. Draw a small amount of air (about 1 mL) into the syringe before loading the sample solution.

1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.

Filters We recommend that you filter buffers and samples using a 0.2 µm filter prior to use. Filtration protects the column and instrument components from a buildup of particulate matter, improving column lifetime and minimizing system down time. Use 0.2 µm GHP Filters for filtering aqueous, non-polar solvents and proteins.

Another aspect of choosing the right filter size is the hold-up volume. This is the volume of liquid remaining in the filter after use. A filter with a low hold-up volume is recommended for use with expensive fluids or those with limited availability. Here are examples of the hold-up volumes of Pall’s non-sterile syringe filter range:
