Our 0.2 µm Acrodisc® syringe filters are designed to protect the unique packing found in UHPLC columns. Using Pall filters prior to sample analysis prevents column plugging and extends column life. Pall incorporates membranes best suited for UHPLC applications to ensure limited extractables that can produce unexpected peaks.

Sep 03, 2013 · The injection volume was 8 μL, and the column temperature was maintained at 35 ºC (95 ºF). Procedure A 0.05% microsphere suspension (average diameter 0.31 μm) in 0.002% Triton X-100 (prepared from a 10% w/w polymer stock), was filtered using either 0.2 μm Acrodisc MS syringe filters or 0.45 μm Acrodisc PSF syringe filters with a nylon

May 07, 2017 · Koeman recommends holding pipettes at 90 degrees to the sample during aspiration, and 45 degrees for dispensing. “Pipettes are made to work with the forces of gravity, so a 90-degree aspiration is important. We don’t see too much variation in the measured volume until the aspiration angle reaches approximately 60 degrees, but 90 degrees is

Hydrophilic polyvinylidene fluoride (PVDF) membranes are commonly used in a variety of general filtration and sample preparation applications. Pall has multiple options for hydrophilic PVDF membrane available targeting specific applications ranging from sterile filtration to biological sample preparation to organic mobile phase filtration.

Acrodisc PSF Syringe Filters feature a large effective filtration area (3.9 cm 2) for increased sample throughput, ideal for sample volumes of ≤ 150 mL. Pall Acrodisc PSF Syringe Filters are designed to be fully compatible for use with automated robotic handling systems offering reliable and worry-free operation.

If the number of cells per 1 mm 2 exceeds 50, dilute the sample and count again. If the number of cells per 1 mm 2 is less than 15, use a less diluted sample. If less dilute samples are not available, count cells on both sides of the hemocytometer (8 x 1 mm 2 areas). Keep a separate count of viable and non-viable cells.

Mar 09, 2022 · For samples with low concentrations of analyte the sample volume used in the kit assay can be increased to increase sensitivity. When doing this the water volume is adjusted to retain the same final assay volume. This is critical for the manual assay format because the assay volume and sample volume are used in the calculation of results.
