Description
Product Overview
CELLTREAT bottletop lab filters are designed for high-performance filtration in laboratory settings, featuring a polyethersulfone (PES) membrane that provides excellent flow rates and low protein binding. These filters are available in two pore sizes, 0.22μm and 0.45μm, to accommodate various filtration needs, from sterilization to particle removal. Each unit is packaged sterile via gamma irradiation, ensuring integrity and readiness for use. Key specifications include package dimensions of 17.2 x 14.4 x 9.8 inches and a lightweight design at 7.04 ounces, with item model number 229705 and ASIN B00APMK49U for easy identification.

Usage
These bottletop lab filters are ideal for research laboratories, pharmaceutical development, and biotech industries where sterile filtration is critical. They are commonly used for filtering cell culture media, buffers, and other sensitive solutions to remove contaminants and ensure sample purity. The filters suit environments requiring aseptic techniques, such as biosafety cabinets, and are targeted at scientists, lab technicians, and quality control professionals who need reliable, consistent filtration results for experiments and production processes.

FAQ
What is the shelf life of these filters?
The filters have a long shelf life when stored in a cool, dry place away from direct sunlight, typically remaining effective for several years if the packaging remains intact.
Can I use these filters for organic solvents?
Yes, the PES membrane is compatible with a wide range of solvents, but it is recommended to check chemical compatibility charts for specific applications to ensure optimal performance.
How do I ensure sterility during use?
Always handle the filters in a sterile environment, such as under a laminar flow hood, and avoid touching the membrane surface to prevent contamination during setup.
Are these filters reusable?
No, these are single-use filters designed for disposable applications to maintain sterility and prevent cross-contamination between samples.
What is the flow rate for these filters?
Flow rates vary based on the pore size and solution viscosity, but the PES membrane generally allows for faster flow compared to other materials, reducing processing time in the lab.
