The Basics You Should Know About Syringe Filter
The syringe filter is a fast, convenient and reliable filter tool commonly used in laboratories. It is beautiful and light in appearance and high in cleanliness. It eliminates the need for membrane change and cleaning filters, with no need for complicated and time-consuming preparations.
It is widely used in the laboratory, for sample pre-filtration, clarification and sterilization filtration of particles, liquids, and air. It is the preferred method for filtering small samples of HPLC and GC and is often used in conjunction with disposable syringes. The filtration diameter is 4 mm to 50 mm, and the treatment amount is from 2 ml to 5000 ml.
The syringe filters provided by HAWACH can provide foundry services according to customer needs. The consistency of the produced batches of the filters is good. From the raw materials to the production process to the delivery management of the inbound and outbound warehouses, there are strict control processes to ensure to the greatest extent.
Material Introduction of Syringe Filter
1.PTFE Material
PTFE (polytetrafluoroethylene) is an effective filter for solvent chemicals and other non-aqueous solutions. A wide range of chemical compatibility, strong chemical stability, and inertia PTFE film is especially suitable for corrosive, strong acid, strong base chemical filtration can also be added ethanol and water to make it have certain hydrophobicity.
2.PVDF Material
PVDF (polyvinylidene fluoride) is suitable for highly corrosive organic solvents with hydrophilic properties and very low protein adsorption. It can filter out moisture in air and gas. PVDF film is coated on the support network, which has strong strength and maneuverability and can withstand high temperature.
3.PP Material
PP (polypropylene) takes food grade isotactic polypropylene as raw material, there are no additives in the whole production process; the physical and chemical properties are stable and have good compatibility; it has a series of pore size, high porosity, large amount of pollution, recoil and high temperature disinfection; good pressure resistance.
4.PES Material
PES (polyethersulfone) has strong hydrophobicity, narrow pore distribution, and accurate pore size, low protein adsorption has good permeability, no pollution resistance to samples, fast filtration speed, good chemical resistance, and has a very good effect on the filtration and clarification of samples.
Quality Service Commitment
The warranty period is 18 months, free maintenance for life. During the warranty period, except for human factors, any defects and failures caused by improper design, material or process of the instrument shall be repaired or replaced free of charge.
Hawach commits to respond within ten minutes after receiving notification from the user that the instrument provided has failed. Furthermore, ensure that spare parts and vulnerable parts are provided to users at the preferential prices in a timely manner.
Breakdown Removal in Operation
In case any breakdown occurs in the operation of a syringe filters, some small tips are available in emergency. Such as follows: do not use a conical tail tool-1.5 needle to prevent material savings caused by the blockage. Prevent blockage and hardening of the material caused by the improper usage and maintain the high mobility of the material.
Additionally, different types of disposable needle filter have built in the corresponding kind of micro-porous filter membrane, if the user needs to know which kinds of the material micro-porous filter membrane is more suitable for sample filtration, please refer to the filter membrane selection chart in the service guide book.
