This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other solutions for activation. This product is only for scientific research by professionals, and must not be used for clinical diagnosis or treatment, or used for food or medicine, and must not be stored in ordinary residences. For your safety and health, please wear lab coats and disposable gloves for operation.

You can choose a PTFE needle-punched filter to improve the filtration efficiency in any area. They provide high-performance filtration through an application-centric design and can be used in various industries that process organic samples.

Filter sterilization, that is, removing microorganisms by physical means such as screening or filter material adsorption, is a commonly used method of sterilization. The filtration method is widely used, and some materials that need to be sterilized cannot be heated, such as many vitamin solutions. In addition to being used in the production of beverages and drugs, the air is often sterilized by filtration. When we usually do microbiology experiments, the sterilized container is usually plugged with cotton at the outlet, which is actually filtering to remove microorganisms in the air, so that there is no microbial contamination in the air entering the container.

PP housing membrane syringe filter refers to a syringe filter wif a housing made of polypropylene (PP).

Polypropylene is a commonly used material for syringe filter housings due to its chemical compatibility, low extractables, and resistance to a wide range of solvents. PP housings provide structural support to teh filter membrane and help maintain its integrity during filtration.
These syringe filters find applications in various fields such as pharmaceuticals, biotechnology, environmental analysis, food and beverage testing, and research laboratories where precise filtration is required to ensure sample purity and integrity.

A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples. Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even sterilization.

Aijiren Syringe Filters is a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particulates are removed from each and every sample, extending analytical column lifetime and minimising injection port or valve damage.

Syringe filter is a small, disposable device used for filtering liquids or gases.It consists of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end, which allows it to be attached to a syringe or other fluid delivery system.
Syringe filters are commonly used in laboratory and research settings to remove particles, microorganisms, or other impurities from samples before analysis or further processing. The membrane filter in a syringe filter acts as a barrier, allowing only the desired components of the sample to pass through while retaining any larger particles or contaminants.
The choice of membrane material depends on the nature of the sample and the substances to be filtered.

When using vents, these syringe filters can prevent moisture from passing through. Usable pH range: 1-14. PTFE can be applied to: filtering organic solvents with strong chemical corrosiveness, filtering strong acid solvents, filtering alkali solvents, compatible with gaseous samples, and can handle high-temperature liquids.

The special color contrast provided on the surface of the MCE film helps to detect particles and minimize eye strain. It is ideal for the recovery and retention of bacteria in colony counting and sterility testing, as well as water/wastewater analysis and other microbiological tests.

PTFE is hydrophobic and needs to be pre-wetted before being used with aqueous solvents. Used for: corrosive solvents, strong acids, alcohols, alkalis, aromatic hydrocarbons. Not suitable for: water-based samples.

Instructions for use and precautions:
1. It must be used with disposable syringes and glass syringes. The interface is standard. Put the needle filter on the syringe first, then pour the liquid into the syringe, press the push rod down, and collect the filtered liquid.
2. Do not use a syringe smaller than 10cc, because the small-volume column may cause the pressure to exceed the upper limit and cause damage to the filter membrane.
3. Only for laboratory use, one-time use, non-renewable.
4. The filtrate at the beginning of the part should be discarded. The volume is about the dead volume of the filter. Taking 25mm as an example, discard the first 1mL filtrate; or pre-clean the filter with 1 to 2mL of solution.

Selected PES syringe filters provide a cleaner sample extract by removing interfering materials and fine particles down to the rated pore size. Performing a syringe filtration step before chromatographic injection helps ensure more consistent and reliable results, and helps protect delicate instruments and extend column life.
