Cobetter sterile PVDF syringe filters are individually packed and made of two layers of hydrophilic PVDF membrane. The first layer is a prefilter with a larger pore size which makes the syringe filter achieve high throughput. This construction prevents the build-up of back pressure typically caused by the blocking of an unprotected membrane. The single-layer syringe filter achieves a high flow rate.

The hydrophilic treatment PVDF membrane achieves both low protein binding and a fast flow rate simultaneously, making it suitable for applications where high protein recovery is desired. Suitable for filtration of protein solutions and mild organic solutions.

The housing is made of premium polypropylene which has a wide chemical compatibility. The molded design ensures higher operating pressures. Luer lock inlet/outlet offers a leak-tight syringe connection.

Features 

· 13, 25 and 33 mm diameter syringe filters

· Double-layer membrane with graduated pore size for excellent loading capacity with fast flow rate

· Exceptionally low protein binding

· Broad chemical compatibility but not resist strong alkali (pH range: 2-10)

· Individually packed, Eliminates sample contamination

Application

· Hydrophilic Polyvinylidene difluoride (PVDF) for biological solutions

· Protein/enzyme solutions

· Mild organic solutions

· Routine sample preparation

· Environmental samples

How to use a syringe filter?

Choose the right type of membrane material based on the properties of your sample. Be careful of the chemical compatibility to avoid extractables and leachables. Read this article about How to choose a syringe filter.

1. Load the sample into the syringe.

2. Attach the filter to the luer-lock of the syringe with a twisting motion. Make sure it is securely attached.

3. Filter the sample. Hold the syringe and filter vertically, and gently press the plunger to push the sample through the filter. Take care not to apply too much force or you may damage the filter.

4. Discard the used filter and repeat for the next sample.

How to use a syringe filter?

Q: What's the sterility method of the syringe filters? And how are they packed?

A: The hydrophilic PVDF syringe filters are sterilized by gamma irradiation. And they are individually blister packed.

Q: What's the advantage of sterile PVDF syringe filters?

A: The hydrophilic PVDF filters are ideal for sterilization of tissue culture media, protein solutions or aqueous solutions for its Ultra-Low Protein Binding.

Q: Does the sterile syringe filter have a prefilter?

A: Yes, our sterile syringe filters are made of two layer membranes. The upper layer with a larger pore size performed as a prefilter, such as 0.65μm prefilter plus 0.22μm for sterilization.
