Sterile Syringe Filters are fast, convenient and reliable small-volume sample filtration devices that are routinely used in laboratories. It saves much time and effort, no need to clean filter or change filter membrane. With light weight, high cleanliness and stylish design, the sterile syringe filter are mainly used for samples pre-filtration, sterilization filtration of laboratory biological fluids, culture media and media additives. Today, HAWACH will discuss the applications and how to choose a suitable sterile syringe filters.
Reliable, fast and convenient, the sterile syringe filter is mainly used for sample pre-clarification, particle removal, liquid and gas sterilization filtration, laboratory biological fluid, culture medium and medium additives sterilization filtration etc.1. Ambient air, exhaust gas, and water quality analysis.
Avoiding other impurities introduction during the filtration process is necessary, when the syringe filter processes chromatographic samples. Such impurities can be: the filter membrane or shell material shed particles and carry them into the filtrate. Therefore, the filter membrane and housing structure materials are very important. We need to choose the filter membranes based on the samples’ properties.■Hydrophilic samples: the hydrophilic membranes should be chosen, which have affinity for water and are suitable for filtering water-based solutions. Available filter membranes are: mixed cellulose ester MCE, polyethersulfone PES, nylon, hydrophilic PTFE, hydrophilic PVDF and so on. For instance, the nylon filter membrane has ultra-low extract content and high protein binding capacity. It is recommended to filter alcohols, cryoprotectants, such as DMSO, glycerin and solvents.
Besides the above factore, we also need to consider the sample’s volume when purchasing a syringe filter. Usually when the sample size is less than 2ml, a 4mm diameter micro filter (customizable) is used; the sample size is between 2-10ml, 13mm For the diameter filter, when the sample volume is greater than 10ml, use a 25mm diameter filter; when the sample volume exceeds 100ml, use a 33mm diameter syringe filter.
HAWACH provides various syringe fiters for different usages and the advantages are as follows:Various membrane types: MCE, NYLON, PVDF, PES, PTFE, CA
Whether your research requires pre-filtration, sample preparation, sterile filtration, laboratory filtration, or exhaust, the HAWACH syringe filter is a must-have appliance in your laboratory.
