Whatman Pore Size 0.45 µm Mini UniPrep Syringeless Filter (Amber)

The Whatman Mini UniPrep Syringeless Filter is an innovative and compact filtration device designed for simplified sample preparation and filtration in laboratory settings. It combines the filtration membrane, vial, and plunger into a single unit, eliminating the need for multiple components and reducing the risk of contamination.The Mini UniPrep Syringeless Filter is designed for small-volume sample processing, typically ranging from 0.5 to 2.0 milliliters. It features a syringeless design, allowing users to filter samples directly into the attached vial by simply pushing the plunger. This streamlined approach not only saves time but also minimizes the chances of sample loss or mishandling.The filter units are available with various membrane materials and pore sizes to suit different filtration needs, such as particle removal, clarification, or sterilization. Common membrane materials include nylon, polyethersulfone (PES), regenerated cellulose, or polytetrafluoroethylene (PTFE), each offering specific advantages based on the sample type and application requirements.The Mini UniPrep Syringeless Filter is widely used in biological, pharmaceutical, and environmental laboratories for tasks like sample preparation for chromatography, protein or nucleic acid purification, and particulate removal from small-volume samples. Its compact size, user-friendly operation, and reliable filtration performance make it a valuable tool for laboratory filtration processes.
