purchased from Sigma-Aldrich Corp. (St Louis, MO, USA). HPLC grade acetonitrile (ACN) and methanol (MeOH) were from Honeywell (Muskegon, MI, USA). Thirteen popular food additives were selected to assess filter performance, including preservatives
9/1/2019 · In the next step, the MWCNT composite membranes, with a load of 0.15 mg cm −2 (3 mg membrane −1), were placed into a sterilized swin-lock plastic membrane holder with the diameter of 25 mm (Sigma-Aldrich, Whatman ®) and connected to the Luer-lock
Fluoropore™ Membrane is a hydrophobic, polytetrafluoroethylene (PTFE) polymer membrane bonded to a high density polyethylene support. (Catalogue numbers containing ""FHUP"" have no backing.) Fluoropore™ Membranes provide broad chemical compatibility, high flow rates and consistency. Omnipore™ Membrane is hydrophilic PTFE compatible with
1/6/2017 · Moreover, the high separation performance of the studied membrane pervaporation on a 70 wt% IPA aqueous solution (permeation flux: 330 g h −1 m −2, water concentration at the permeate side, C w: 100%) is especially attractive for further studies in practical
1/11/2016 · A PTFE (pore size = 0.2 μm, Meari) sheet was used as a substrate of the omniphobic coating.Prior to the FOTS (97%, Sigma-Aldrich) coating of PTFE sheets, SiO 2 nanoparticles (Aerosil 200, particle size = 24 nm, Degussa) were physically attached to the PTFE sheets (3 cm ÿ 3 cm) to generate a hierarchical surface morphology.
1/6/2018 · Firstly, 25 g PTFE emulsion (60 wt.%), 30 μL of BA aqueous solution (4 wt.%) and 10 g PVA aqueous solution (10 wt.%, improving spinnability) were blended by the magnetic stirring at room temperature for 30 min , .Then, the different contents of hydrophilic SiO 2 nanoparticles (2.0, 4.6, 7.3 and 10.0 wt.% vs PTFE) were added in the spinning solutions under gentle magnetic stirring for at least
3/1/2021 · The catalyst ink was a mixture of Pt/C (Tanaka Kikinzoku Kogyo K.K., Japan, 46.2 wt% Pt) and 5 wt% Nafion (Sigma Aldrich, Japan), ethanol (Sigma Aldrich, Japan), and deionized water. Whilst nanocellulose will be explored in the future as an electrode ionomer in its own right, at this stage it is important to investigate these new membranes using state-of-the-art electrocatalyst layers.
Choosing the Best Syringe Filters for Biological Sample Filtration Authors Limian Zhao and Phu Duong Aijiren Technologies, Inc. Application Note Proteomics & Protein Sciences Abstract Aijiren Captiva Premium PES syringe filters are evaluated and compared to
1/1/2021 · We investigated the experimental and theoretical study of the high performance PTFE-0.45 membrane for the VMD application. A theoretical model based on heat and mass transfer processes is developed to understand and predict the performances of
PTFE, also known as polytetrafluoroethylene is a fluorocarbon solid with a high molecular weight that contains carbon and fluorine. Its membrane technology is a non-reactive filter that is hydrophobic or hydrophilic in nature and is strongly resistant to solvents, acids, and bases.
6/9/2014 · The details of experimental set up are explained in our earlier publication on high temperature/high pressure DCMD for flat porous PTFE membrane (Singh and Sirkar, 2012). In brief, brine from the brine tank was pumped to the shell side of the heat exchanger where it was heated by steam circulated on the tube side of the heat exchanger.
