If a solution is to be drawn into a syringe and then filtered through a membrane filter, use the following procedure: A regular needle (or a depth filter needle) is attached to the syringe. The solution is pulled into the syringe. Air bubbles are removed from the syringe. The needle is removed from the syringe.
2016/9/28 · This is the most basic method of using a syringe filter. Load the sample into the syringe. Attach the filter securely with a twisting motion. With a luer slip syringe, this is about one quarter turn as the filter is pushed on. If the syringe has a luer lock (as in this
These Filters greatly reduce the need to carry out separate prefiltration step with difficult to Filter samples and allow you to Filter difficult samples with less hand pressure. GD/X Syringe Filters can process three to seven times more sample volume than standard syringe Filters.
Never re-use a syringe filter, even if it looks perfectly clean. Whatman products filter out extremely fine particulate that may not be visible to the naked eye. Ensure the consistency of your results by discarding filters after a single use. Quality. Speed. Comfort.
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.
Sterlitech MCE syringe filters are made using high-quality nitrocellulose polymer (cellulose nitrate and cellulose acetate). This material is easily blocked to give it a very low background. Read More. MCE syringe filters are hydrophilic and designed for efficient clarification and filtration of aqueous samples.
Available in three color-coded pore sizes: 0.2µm (blue), 0.45µm (yellow) or 1.2µm (red) Filtration so effective it can double the throughput. Ideal for sample cleaning, particle removal and sterile filtration of aqueous solutions. Maximum user convenience.

0.45 µm Syringe Filter, PES (Sterile), Yellow, ⌀ 33 mm. Large filtration surface area allows you to filter your sample more easily. Low hold-up volume provides maximum recovery of your solution. Surfactant-free membrane for cleanliness in downstream applications.
Don’t use with: Benzyl alcohol. Sterilization: Syringe filters can be sterilized by autoclave at 125° for 15 minutes. Applications: Dissolution testing, filtration of high particulate samples, air filtration, recovery of DNA from biological samples.
Hydrophilic PVDF syringe filters are typically used for general filtration applications (both aqueous and organic), aggressive solvent filtration, sterilizing filtration of biological solutions, and HPLC sample preparation. They are characterized by high strength and porosity, a high flow rate, and low extractable.
Features. Filter insertion in clean room by manual as well as fully automated means. Molding in place, over molding and support structure molding of fragile media. Ultrasonic welding of barrel structure for increased leak / burst resistance. Multi-process mold extensions for inclusion of single or multi-level prefiltration media.
Polyethersulfone (PES) membrane for high flow and low binding Two membrane pore sizes: 0.22µm or 0.45µm Filter systems include bottle top filter and solution bottle with cap Bottle top filters fit standard 45mm threaded solution storage bottles Packaged sterile (gamma irradiated) in bags.
MilliporeSigma™ Millex™ Sterile Syringe Filters: MCE Membrane. Designed for sterilizing and clarifying sterile solutions. Millex™ Sterile Syringe Filters: MCE Membrane are ready-to-use, syringe-driven units that have never been touched by human hands during filter assembly.
2019/11/6 · Place the filter tip over the collection container and push the sample through a syringe filter by applying gentle positive pressure. To purge the syringe filter and maximize sample throughput, remove the filter from the syringe and draw air into the syringe.
