Sterile Bottle Top Filter System

Greiner Bio-One Bottle-Top Filtration: Speed Meets Sample Integrity

The Greiner Bio-One filtration system is the premium bottle top filter choice for research laboratories requiring absolute sterility without compromising on workflow speed. Specifically engineered for the vacuum filtration of cell culture media, buffers, and aqueous protein solutions, this system protects your samples while accelerating your process.

High-Performance PES Membrane

The heart of the system is a high-porosity Polyethersulfone (PES) membrane designed for two critical functions:

• Maximum Protein Recovery: The low protein-binding material ensures that vital growth factors and supplements stay in your media rather than getting trapped in the filter.

• Rapid Throughput: Optimized for speed, the membrane enables fast flow rates even when handling viscous solutions like Fetal Bovine Serum (FBS).

Certified Sterility & Compliance

For total peace of mind in sensitive cell culture applications, every unit meets rigorous global standards:

• SAL 10^-6: Gamma irradiated in accordance with ISO 11137.

• Pure Results: Certified non-cytotoxic, non-pyrogenic, and free from detectable DNase/RNase.

• Traceability: Each filter is clearly marked with its batch number and pore size to simplify GLP documentation.

Ergonomic & Secure Design

We’ve focused on the small details that improve laboratory safety and ease of use:

• Universal Connector: A stepped hose connector ensures a secure, airtight fit for various vacuum tube diameters—no adapters required.

• Anti-Tip Stability: The wide-based reservoir bottle provides a low center of gravity, preventing accidental spills under vacuum pressure.

• Superior Seal: Heavy-duty buttress threads ensure a robust, leak-proof bottle seal for long-term storage.
