Bottletop Filters

Lab bottletop filters are essential tools for laboratories, designed to provide efficient filtration directly into bottles. These filters are commonly used for sterilizing and clarifying cell culture media, biological solutions, and other laboratory fluids, ensuring purity and safety in experimental procedures.

A key feature of these filters is their high flow rate membranes, which allow rapid filtration without compromising performance. The advanced membrane technology removes particulates, bacteria, and fungi, guaranteeing contaminant-free solutions. Many models come with a unique liquor bottle thread adapter, enabling secure attachment to a variety of bottle types, adding versatility and convenience.

The practical benefits are clear: faster processing times and reliable results. The filters are available in various pore sizes and membrane types, catering to different laboratory needs and ensuring compatibility with a wide range of applications.

Options include different volumes and membrane materials like PES and PVDF, making them suitable for various filtration tasks. Some models are also compatible with vacuum or pressure filtration setups, further expanding their usability.

Thomas Scientific also offers a number of other filter products, such as filter assemblies and filter paper.
