Over 120 different syringe filter product codes offer one of the most diverse options for meeting users’ application needs, from medical device sterile filtration to research use cell culture
The membrane of the hydrophobic PTFE syringe filter is chemically resistant to almost all solvents. They can be used together with corrosive media such as strong acids, alcohols, alkalis, aromatic hydrocarbons, etc. This filter is ready-to-use and allowed for simple, fast and reliable super-cleaning of small volume samples for HPLC or GC analysis.
PTFE-T Syringe Filter. DORSAN® syringe filters, manufactured with naturally hydrophobic Polytetrafluorethylene membranes (PTFE). This is the type of membrane most widely used in the preparation of samples for HPLC analysis. PTFE is widely used due to its great resistance to the majority of acid, alkaline and solvent products.
Millex-LG for Samplicity G2, 0.20 µm, hydrophilic PTFE, 33 mm, non-sterile, This 33 mm syringe filter with a Hydrophilic PTFE membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.45 µm pore size used in preparation of aqueous & organic solutions prior to chromatography or other instrument analyses.
Jan 25, 2017 · While using Hydrophobic PTFE syringe filters for aqueous media, it is essential to pre-wet the media with methanol or ethanol. The Characteristics and Benefits of PTFE Filters: The membrane filters are used for gas and liquid filtration, venting purposes, and cleaning acids.
As well as being suitable for the filtration of organic solvents in applications such as HPLC and UHPLC sample preparation, the hydrophobic nature of the PTFE membrane makes these syringe filters ideal to use in gas filtration or as a moisture barrier in venting applications. 25 mm Standard Acrodisc Syringe Filters
Sep 28, 2016 · The majority of syringe filters used do not allow you to reclaim the solid. They are often used before analysis to remove any solid, undissolved, material. Other, filter holder (in-line) types allow you to regain your filter (Figure 1). Syringe filters normally use membrane type filters which have a specific particle size cut off (e.g. 0.45 μm).
Therefore, it is very important to scientifically master how to use the syringe filter. 1. Syringe filter sterilization, including gas filters or liquid filters, should be tested for integrity before and after use in accordance with the integrity test procedures for sterile filters. 2. After the integrity test is over, the membranes and filters used for aseptic production need to be sterilized. 3.

Target Polypropylene Syringe Filter Housings Meet The Requirements of 21 CFR 177.1520. Target 2 PTFE (Hydrophobic) Syringe Filter 0.2 µm, 17 mm, 100 Pk. Target2 Syringe Filters are an ideal choice for general purpose laboratory use. Robust and reliable, they deliver excellent performance at an attractive price.
Feb 10, 2022 · Precautions for using syringe filters 1. Do not use a syringe filter smaller than 10 cc, because the small-volume column tube may cause the pressure to exceed the upper limit, resulting in damage to the filter membrane or personal injury. 2. Only for laboratory use, one-time use, non-renewable. 3. The filtrate at the beginning should be discarded.
Feb 17, 2020 · Attach the filter securely to the syringe using a twisting motion. Pour the sample solution from the unpreserved fill bottle into the top of the syringe leaving space for the plunger. Reinsert the plunger. Note: The individually packed sterile syringe filter can be held in the original package to minimize contamination while attaching the syringe.
Feb 22, 2022 · Sterile filters include a polypropylene microfiber pre-filter layer to improve the filtration of particulate-laden liquids that are difficult to filter with single-layer syringe filters. Red polypropylene housing & microfiber pre-filter layer; PTFE Hydrophilic membrane
