LAB SAFETY SUPPLY
Frequently asked questions
Common questions about LAB SAFETY SUPPLY from 3G Electric.
What membrane materials are available in LAB SAFETY SUPPLY syringe filters?
LAB SAFETY SUPPLY syringe filters are offered with several membrane materials: polyethersulfone (PES), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), nylon, and mixed cellulose esters (MCE). Each material has different chemical compatibility and flow characteristics. For example, PTFE is hydrophobic and suitable for organic solvents, while PES is hydrophilic and often used for aqueous solutions. The specific membrane material is indicated in the product specifications, allowing you to select based on your sample type.
Are LAB SAFETY SUPPLY vacuum filter systems reusable?
No, LAB SAFETY SUPPLY vacuum filter systems are designed for single-use applications. The filter unit includes a PES membrane with a 0.22 µm pore size and a 90 mm diameter, along with a stopper and a 500 mL upper capacity. The system is intended for sterile filtration of aqueous solutions and should be disposed of after use to avoid cross-contamination. The product is supplied sterile and is not designed for autoclaving or reuse.
What is the difference between the 0.22 µm and 0.45 µm pore sizes in LAB SAFETY SUPPLY syringe filters?
The 0.22 µm pore size is typically used for sterilization by removing bacteria and other microorganisms, while the 0.45 µm pore size is used for general particle removal and clarification. Both are available in LAB SAFETY SUPPLY syringe filters across various membrane materials. The choice depends on your application: use 0.22 µm for sterile filtration and 0.45 µm for removing larger particulates without affecting microbial content.
What connection types do LAB SAFETY SUPPLY syringe filters have?
LAB SAFETY SUPPLY syringe filters feature a female Luer Lock inlet and a male Luer Slip outlet. The female Luer Lock provides a secure connection to the syringe, preventing accidental disconnection during use. The male Luer Slip outlet allows for easy attachment to a needle or tubing. This standard configuration is compatible with most laboratory syringes and downstream equipment.
Can LAB SAFETY SUPPLY syringe filters be used with organic solvents?
Compatibility with organic solvents depends on the membrane material. For example, PTFE membrane filters are chemically resistant to many organic solvents, while PES and nylon may be less suitable. LAB SAFETY SUPPLY offers PTFE syringe filters (e.g., SKU 11L865 and 11L862) that are appropriate for organic solvent filtration. Always verify the chemical compatibility of the specific membrane and polypropylene housing with your solvent before use.
