SYRINGE FILTER MILLEX-FG, MILLIPORE (PTFE Membrane, 0.2 µm, 25 mm, Sterile) This syringe filter is designed for venting and gas filtration purposes. This filter can be used in applications such as: Sterile filtering of gases, venting sterile containers, and in-line vacuum pump protection.
A variety of membranes and housings ensure chemical compatibility with a range of samples and solvents. Choose From a Variety of Membranes • Millex-LCR filter contains a Millipore-exclusive hydrophilic PTFE membrane and are HPLC-certified for low levels of UV-absorbing extractables. They provide the cleanest sample for HPLC analysis.
Feb 01, 2017 · Membranes with a PTFE/PVA mass ratio lower than 6:1 had PTFE ultrafine fiber diameters ranging from about 100–500 nm (Fig. 7a-2-c-2). As the mass ratio of PTFE/PVA increased, the membranes became PTFE resins rather than fibers (Fig. 7c-2-d-2). The surface morphologies of the membranes were also evaluated by AFM.
Sample preparation Sample preparation 1. Filter supernatant/sample through Millipore HPLC filters (Millex-HV 0.45µm PVDF 4mm non-ster 100/Pk, cat.no. SLHVR04NL). 2. Add to a 1.5 ml glass vial: MilliQ 875 µl 0.1 M Borate buffer 25 µl 1 mm (internal standard, e.g. Norvaline) 25 µl Sample/standard 25 µl + Total 950 µl 3.

Nov 01, 2010 · The extracts were dried by rotary evaporation until 3 ml; the residue was filtered through a membrane Millex LCR (PTFE 0.45 μm pore size; 13 mm diameter). After dryness, the extract was dissolved (200 μL) with a mixture of dichloromethane:methanol (1:1). An aliquot of the extract was used for these analyses.

Preface . This manual contains procedures proposed in the literature for microwave-assisted digestion of organic and inorganic samples. The literature search was based on papers published in 2006 and 2007, because previous years were covered in the first version of this manual [1].
Millex® hydrophilic PTFE syringe filters boast broad chemical compatibility and are HPLC-certified, guaranteeing low extractables. With their robust performance, these filters can be used for a variety of samples without the risk of membrane failure or sample contamination.
A 47 mm diameter lter of each sample was extracted three times for 30 min with a mixture (dichloromethane:methanol, 4:1 v/v) under ultrasonic agitation. The extracts were dried by rotary evaporation until 3 ml; the residue was ltered through a membrane Millex LCR (PTFE 0.45 m pore size; 13 mm diameter).
After swirling for several minutes, the DMSO was transferred into an organic-safe PE syringe barrel equipped with a Millex®-SR 0.45 μm filter unit (Millipore, Solvent Resistant, PTFE Membrane). The samples were filtered and then analyzed by fluorescence spectroscopy using a RF5000U spectrofluorophotometer (Shimadzu, Columbia, MD) set to an
Merck Millex™-FG Syringe Filter Unit, Hydrophobic PTFE, 0.2 μm Features a hydrophobic Fluoropore™ (PTFE) membrane. Millex™-FG Syringe Filter, 0.20μm, Hydrophobic PTFE provides broad chemical compatibility and is ideal for filtering samples in organic solvents or to prevent back-streaming of atmospheric moisture in venting applications.
