FAQs
What is the Sartorius Glass Vacuum Filtration Device?
The Sartorius Glass Vacuum Filtration Device is a glass vacuum filter holder designed to support 24 mm and 25 mm membrane filters for precise laboratory vacuum filtration. It provides a reliable way to remove particulates and clarify liquids under vacuum conditions with consistent performance.
What filter sizes does this device support?
This vacuum filtration holder is compatible with 24 mm and 25 mm diameter membrane filters, giving flexibility in choosing filter media for different lab filtration needs such as sterile filtration or clarification.
What materials is this device made from?
The device is constructed primarily from glass, offering excellent chemical resistance and easy cleaning. Membrane support options include either a glass frit filter support or a PTFE‑coated screen, depending on whether uniform particulate distribution or easier cleaning is needed.
What are the common uses for this vacuum filtration device?
It’s ideal for vacuum and sterile filtration, as well as analytical sample preparation, where particulate removal and sample clarity are critical. It fits into a vacuum setup with a flask and a vacuum source for efficient filtration.
How does the glass frit support differ from the PTFE screen?
The glass frit support promotes even distribution of retained particles, making it great for residue analysis. The PTFE‑coated screen is easier to clean and preferred when the filtrate (liquid portion) is essential or when removing residues from the support is difficult.
