Tube-tip format (optional) for accurate dispensing into a micro-vial. Choice of membrane or glass microfiber filter media. Sterile option for critical applications. Wide range of membranes. 13 mm diameter syringe filter. Sample volume up to 10 mL. Low hold-up volume < 25 μl ensures maximum sample recovery.
Membrane filters: 1. Most useful for microscopic examination of water supplies (e.g. coliform counts) since most foods will clog the filters. 0.45 µm-pore filters allow water to pass but trap bacteria. 2. Filters are especially useful for samples with low numbers of bacteria since large volumes of fluid can be passed through. 3.
Apr 29, 2017 · For the sample preparation step syringe filters were used with a dual purpose, pre-concentration of bacteria from the water sample (step 1, Fig. 1) and as μL reactors for cell lysis and GUS extraction (step 3, Fig. 1). Beside the pre-concentration of bacteria, the filtration (step 1) also removes the sample matrix, which can contain compounds

Nov 08, 2019 · In addition, the filter-based method can easily be used with large sample volumes because of the easy loading step using the syringe, allowing samples of up to 50 mL to be processed easily.
Aug 13, 2017 · The bulk, unpreserved sample was kept in a fridge (4 °C) for a period of a month, and the sample preparation techniques repeated on this sample. This was done to assess the validity of air drying lichen samples and storing them for an undisclosed period of time before chemical analysis as has been done previously (Demiray et al. 2012 ).
ASE SAMPLE PREPARATION Place approximately 6 g of ASE Prep DE in a mortar and then weigh and record to the nearest 0.1 mg, 3–4 g of homogenous sample on top of the ASE Prep DE. Using a pestle, grind the sample with the ASE Prep DE and then transfer the mortar with its contents to a microwave oven for drying. Up to five 3–4 g samples
