Lead Times May Vary.
The filter’s core strength is its capacity and speed. It features Coarse Porosity and a Fast Flow Rate that allows for rapid processing of large sample volumes. The thick filter media provides excellent loading capacity, making it highly effective for samples with high solid content. Furthermore, the glass microfiber is binder-free, ensuring sample purity and preventing interference in sensitive analytical applications. This filter is the cost-effective and reliable solution for optimizing your multi-stage filtration protocols.
Features:
- Ideal for high volume and repetitive routine laboratory filtering
- Widely used as a membrane prefilter to greatly extend the life of finer membranes
- Thick filter media provides a good loading capacity for high-particulate samples
- Binder-free to ensure sample purity in sensitive analyses
- Coarse porosity (2.7 µm) and Fast Flow Rate
- Available in a wide range of sizes to fit most filter holders
