Smooth filtering low residual rate Syringe Filters

In the analysis of high performance liquid chromatography (HPLC), the packing of chromatographic column has smaller particle size and is easily blocked by impurity particles. Therefore, samples and solvents need to be pre-filtered to remove particulate pollutants and protect the instrument. Ion chromatography, commonly used in environmental analysis, also requires that inorganic pollutants should not be introduced into sample pretreatment. Needle filter can be used in HPLC analysis and IC analysis, and filtering sample solution is an important step in sample pretreatment. Ronghua uses the most advanced testing methods and production technology to produce needle filters with excellent quality. The product quality is far superior to other domestic counterparts. It fills the gap of domestic high-end products.

Features and Benefits:

1. 4 kinds of membrane size: diameter 13mm,25mm,33mm,50mm

2. 2 kinds pore sizes:0.22 and 0.45 μm (other size can be customized)

3.Selection of high-quality sanitary grade polypropylene material for the shell of needle filter

4.The structure design of needle filter product is precise, which ensures the fluency of filtration, rationalization of internal space and low residual rate, thus reducing the waste of samples.

5.The edge of the needle filter is threaded to prevent slippage.

6.The needle filter has stable membrane quality and zero difference between batches, which ensures the consistency of analysis results.

7.Acupuncture filter membranes have precise pore size, providing comprehensive protection for your instrument and chromatographic column.

8.Needle filters are clearly labeled to avoid confusion.

9.Needle filter Ruhr interface with lock to prevent filter from flying out due to excessive pressure

Application:

1. Filtration and clarification of small volumes

2. Sterilization of aqueous and dilute organic solvents

3. HPLC sample preparation

4. Biological sample preparation

5. Don't use with: Acids, Aggressive Halogenated hydrocarbons, protein samples (Nylon is a high binder)
