Syringe Filters
Cobetter syringe filters feature fast flow rate and low hold-up volumes. They are available in 13mm, 25mm and 33mm. The syringe filters are used for particle removal from samples prior to HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. They are produced with exceptional quality to ensure uninterrupted performance with consistent and reliable results. Cobetter Syringe filters are single-use and can be pre-sterile by gamma irradiation. Sterile syringe filters are ideal for sterile filtration of cell culture media and buffer.
Overview
Color-coded Syringe Filters
Cobetter color-coded syringe filters are ideal for particle removal with a sample volume of 1-200mL.
Features
- Nylon Syringe Filter---Low extractable. Filtration of mixed solvents and solvents.
- PES Syringe Filter---High flow rate. Filtration of tissue culture media.
- PVDF Syringe Filter---Low protein binding. Compatible with protein solutions and mild organic solutions.
- PTFE Syringe Filter---Maximum chemical resistance. Filtration of mixed solvents and solvents.
- PP Syringe Filter---Broad range of pore sizes. Prefiltration and solvent filtration.

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 compatible 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 next sample.
How to sterilize syringe filters?
Autoclaving
Only autoclavable syringe filters can be autoclaved. They can withstand autoclaving at 121°C (up to a maximum of 130°C) for 30 minutes, and this process can be repeated up to 20 times. However, we recommend using it only once for optimal performance after autoclaving.
Gamma Irradiation
Gamma irradiation involves exposing the filters to high-energy gamma rays, which can kill microorganisms such as bacteria, viruses and fungi. This method is typically used for large-scale sterilization in a relatively short time. Cobetter sterile syringe filters are gamma irradiated and individually packed.
Additionally, be sure to handle the filters with clean gloves or use it in the clean bench to avoid introducing contaminants while using.
