PVDF Syringe Filter Manufacturer

Chromatography commonly used in environmental analysis requires that no inorganic contaminants be introduced during sample pretreatment. In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

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.

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

Aijiren Tech Aijiren Syringe Filters are 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.

As an important tool for filtering reagents, the Nylon syringe filter plays a very important role, especially in chromatographic consumables. A slightly larger impurity particle in the reagent may cause clogging of the instrument.

Syringe filtration is a crucial technique in laboratory settings, playing a vital role in sample preparation for various analytical methods.

The syringe filters are available in various pore sizes and membrane materials to accommodate different filtration requirements. They are suitable for a wide range of laboratory applications, including sample preparation, clarification, and sterilization. The filters provide reliable performance and consistent filtration results, contributing to accurate and reproducible data in analytical chemistry, microbiology, and other fields.

PVDF syringe filters are made of hydrophilic PVDF membrane and a polypropylene overmold housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes.

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.

Disposable non-sterile syringe filter devices are designed to provide fast and efficient filtration, premium quality and economy. The membrane could be PTEF, PVDF, PES, Nylon, MES, PP, CA, and can be suitable for different situations.

In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.

Sterile syringe filters are syringe-operated filters for the clarification of aqueous solutions (column eluate, tissue culture additives, HPLC samples, etc

The membrane materials produced by Aijiren are provided by the most famous people in the industry, and in the ISO9000 certified production process, under certified clean room conditions, the latest manufacturing technology is used to ensure high-quality and stable products to achieve the highest standards . All syringe filters are HPLC certified.

The syringe filters are designed for easy and efficient filtration of liquids and gases. They feature a syringe-like structure with an inlet and outlet, allowing for direct attachment to a syringe or other fluid delivery systems. The filters remove particulates, microorganisms, and unwanted substances, ensuring clean and clarified samples for analysis.

PTFE Syringe Filter is resistant to almost all corrosive chemicals, which makes PTFE syringe filters an ideal choice. However, the disadvantage of natural hydrophobic PTFE is that after many chemicals are diluted with water, the aqueous solution cannot pass through. Need to be wetted with water in advance.

Aijiren sterile PES syringe filter
100% integrity test, individual packaging, gamma radiation
Diameter: 13mm, aperture: 0.45um, 100/pack
In line with ISO certification, quality is guaranteed
Applications: Preparation of tissue culture media, sterile filtration and clarification of biological fluids, probe solutions, protein and enzyme filtration, hybridization buffers, etc.

The PES film is sealed in the polymer shell without the use of any adhesive. Each unit can provide ETO or Gamma radiation disinfection, and ensure that there is no pyrogen.

Polyethersulfone (PES):?Hydrophilic, stable in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than PTFE. Temperature resistant. pH range ~3-14 (sometimes quoted as 1-14).

The shell of PTFE Syringe Filter is made of polypropylene (PP) with excellent chemical stability. It is made of different colors, which is convenient for users to distinguish products of different materials and avoid confusion. The filter membrane adopts imported high-performance filter membrane with stable product quality and good reproducibility. It is an ideal choice for laboratory filtration of samples. The standard interface is convenient to connect to various syringes, and it can also be directly connected to the needle of the 7725 valve, and the sample can be injected directly after filtration.

13 mm Syringe Filters: For sample volumes <10 mL range; Ideal choice for most applications; Holdup (dead) volume is <15 ul; Female inlet luer lock; Maximum operation pressure <15 bar; Bubble point: Hydrophilic 2-3 bar; Hydrophobic 1-1.2 bar.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. Therefore, samples and solvents must be pre-filtered to remove particulate contaminants and protect the instrument.
In addition, chromatography commonly used in environmental analysis requires that no inorganic contaminants be introduced during sample pretreatment.

Sterile Syringe Filters
While the primary function of a syringe filter is to remove particulates from a liquid sample, you will select either a sterile or non-sterile filter, depending on the end application.
Sterile syringe filters are used to sterilize non-sterile solutions or clarify sterile solutions. Learn more about sterile filters by application.

Due to the high hydrophobicity of the PVDF membrane, it needs to be immersed in ethanol, methanol or other suitable 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.

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.

A syringe filter (sometimes called a wheel filter for its wheel-like shape) is a single-use membrane based filter cartridge, to be attached with a syringe to remove impurities in liquid solutions. This pre-filtration step is vital in preventing damage to instruments (e.g. liquid chromatography, ICP, etc.).
