6 Methods to Learn More About The Syringe Filter

We are in a fast-paced world where the need for rapid and simple sample preparation is important. Hence, the syringe filters are designed to provide a high flow rate and throughputs compared to the competing products. The syringe filter is made for single use, and it is directly attached to the end of the syringe for better use. These filters might come with Luer lock fittings, and the use of the needle is optional in them. When required, it might also be fitted at the end of the syringe filter. 

A sterile syringe filter comes with plastic housing and a membrane that acts as a filter. The fluid needs to be purified by drawing up from the syringe using filters. Also, it might be forced out of the filter for a better effect. Here is more to learn about syringe filters. Read along to know more. 

More about Syringe Filters 

Talking about the scientific use of the filters then it is available in different sizes between 0.2 or 0.22 µm and 0.45 µm pores. These sizes are ideal for HPLC use, and the smallest size needle has a microfilter pore size of 0.02 µm with a membrane diameter of 13, 25, 30, and 33 mm. 

The syringe filter body might be made of a material such as polypropylene and nylon. The filter membrane is also made of PTFE; treated products and nylon have some particular purposes. The filters can reduce the particles from the samples before HPLC does the analysis. Here we have added six ways that can help you to know more about the syringe filters. Let’s have an accumulated look over such factors. 

Bubble Point

The bubble point test is known to be a non-destructive test that does not come with a filter. It can also be used for testing the integrity of the membrane or filters as an alternative for destructive tests for sterilizing membranes. This test helps in detecting minor defects correlating with the bacteria passage test. 

Syringe Filter Size

The syringe filters come with different diameter sizes between 4 to 50 mm. The larger the diameter will be, the more particles can be captured over the filter surface before even blocking and leading to backpressure. Also, the force might be applied to the syringe plunger for even extracting the purified material from the sample. 

The size of the syringe filter can be between membrane filters inside the syringe. There are four different main sizes such as 4mm, 13mm, 25mm, and 33mm. The diameter of this membrane can also affect the reagent amount that can be filtered using a filter. 

Pore Size

The pore size of your syringe filter is known to be the size of the membrane pore. It also depends on the contaminants that you wish to remove the reagent. For instance, if you are using a 0.2 μm membrane, you can make it free from the free-living bacteria, and a 0.8 μm size membrane can remove fungi, fungal spores, and yeast. Lastly, the 0.45 μm sized membrane can remove most of the bacteria from the sample. 

Sterilization

Sterilization is one of those processes that disrupt the microorganisms of DNA and removes them from the syringe filters. Hence, there are typically two ways of giving sterilization to the syringe filters. These methods are the ethylene oxide sterilization method and gamma irradiation sterilization method. The use of methods is dependent on your need for the amount of filtration required. 

Material 

The syringe filter comes in different shapes and sizes and membrane material. Some of the most common materials used in making the filter membranes are glass fiber, cellulose acetate, polyethersulfone, polypropylene, nylon, polytetrafluoroethylene, and regenerated cellulose. 

Luer Lock 

The Luer lock system is a standardized system over small-scale fluid fittings for making the leak-free connection between two parts. These locks are common in the laboratory and medical instruments. These are also described as the male-taper fitting, and it has a female mating part. 

The syringes are also among the most usual medical instruments that use a Luer lock system and a male Luer-lock connection. This connection primarily fits the female needle that can be screwed into the locker. Furthermore, these locks can also be split in two different ways by connection type, such as slipping and locking.
