Syringe Filters - Pall Corporation
During dissolution testing, non-sterile syringe filters are essential to remove undissolved particulates from a drug sample before analysis by high-pressure liquid chromatography (HPLC). Since dissolution testing mimics the process of drug absorption in the human body, these particles must be filtered so the HPLC instrument will provide
Membrane Filtration: Choosing the Correct Type of Filter
Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration. Here, we explore different filtration properties and how to take a preventative—rather than reactive—approach, minimizing time spent troubleshooting and maximizing efficiency.

3.4.3. Seal the vials with PTFE-lined caps and allow them to extract/desorb for 1 h. Shake the vials vigorously by hand several times during the extraction/desorption time. 3.4.4. If necessary, transfer some of the solution from each of the 4-mL vials to smaller glass vials suitable for an autosampler.

An optimized HPLC method for soil fungal biomass
Aug 01, 2014 · A 20 μL sample or standard is injected into the HPLC and eluted with pure methanol on a C18 HPLC column (Phenomenex, 150 × 4.6 mm; 3 μm) at a flow rate of 1.2 mL/min. With these parameters the elution time was near 6.5 min. Extracts should be analyzed with HPLC as soon as possible, certainly within 24 h, and must be stored at 4 °C.

Sep 01, 2016 · Crude extracts and fractions were diluted at 20 mg/mL in methanol (MeOH) and filtrated over 0.45 μm PTFE syringe filter before HPLC analysis. For HPTLC analyses, crude extracts and creams were dissolved in MeOH at 2 and 20 mg/mL respectively, ultrasonicated for 15 min and centrifuged: 2 μL of each supernatant were systematically applied on

Defining a Pore Size and Sterile Filtering; 0.2 Micron vs. 0
Before 0.2 and 0.22 micron filters became standard, it was thought that filters with an absolute rating of 0.45 micron were thought to be sufficient to strain out even the smallest bacteria. However, the discovery of Brevundimonas diminuta, showed that there were still bacteria capable of passing through a 0.45 micron filter in large quantities.
