Due to the high hydrophobicity of the PVDF membrane, it needs to be soaked in an appropriate solution such as ethanol before use to achieve the purpose of activation and make the membrane easier to bind proteins. This product is compatible with many dyes, such as Ponceau-S red, Coomassie brilliantblue, Sypro ruby, Transillumination, Toluidine blue, CPTS, Colloidal gold, India inkAmido black. Among them, after dyeing with dyes such as Ponceau and CPTS, the dyes can be washed off and the film can be used for further analysis; while dyes such as Coomassie Brilliant Blue, India ink, and amide black are irreversible, the film cannot be used after dyeing. For further analysis.

Our Syringe Filters are high quality, well packaged and sold at a fair competitive price. They are available in most of the major membrane materials including Nylon, PTFE, PES, MCE, PVDF, CA, PP, and GF which are supplied in 13mm, 17mm, 25mm and 30mm formats in virgin polypropylene housings.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

Syringe filters are a fast, convenient and reliable filter tool that is routinely used in laboratories. No need to replace membranes or clean filters, which eliminates the need for complex and time-consuming preparations. Widely used in pre-sample filtration, particle removal, and aseptic filtration of liquids and gases. This method is suitable for rinsing small samples before loading into HPLC and GC, and is often used in disposable syringes.

In the sample application of choosing the appropriate syringe filter and syringe, draw your sample into the syringe and place the filter on the syringe. If you are using a leur lock filter, make sure you have properly secured the filter into the syringe tip .Push a few drops through the filter with the syringe filter facing up and “top”. Place the filter in the overturned collection container and push the sample through the syringe filter by applying gentle positive pressure. The syringe filter to be cleared and the maximum To maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reinstall the filter and push the plunger to force some air through the filter.
