Overview
The 96-well Bio-Dot® and 48-well Bio-Dot SF (slot format) microfiltration units provide easy, reproducible methods for binding proteins or nucleic acids in solution onto membranes. Many experimental protocols can be accommodated by using interchangeable templates. The Bio-Dot SF apparatus focuses sample to a thin line instead of a circle, making quantitation by densitometry more reproducible. Both are available as a complete, independent unit, or as a modular template without the manifold base. Features include:
- Resistance to 100% ethanol, strong acid, and NaOH
- Autoclavability
- Patented sealing gasket to eliminate lateral leakage
- Easy sample application with microplate-based spacing
- Flow valve (3-way) for adjustable vacuum
