Why WOB-L Pumps Matter
Welch’s WOB-L pumps use a piston-driven mechanism to deliver consistent vacuum and pressure without oil contamination. That means fewer service interruptions and cleaner results. The single-head configuration is optimized for moderate-duty applications like:
- Vacuum filtration
- Solid-phase extraction
- Degassing liquids
- Aspiration of biological samples
Compared to diaphragm pumps, WOB-L units offer higher flow rates and better pressure stability. They’re also quieter than rotary vane systems and require less maintenance.
FAQs
Typical models reach down to 60 Torr, suitable for most lab filtration and aspiration tasks.
