WOB-L® Standard Duty Vacuum Pumps
The WOB-L® Standard Duty Vacuum Pumps are engineered for a variety of essential laboratory and industrial applications. Offering robust performance, these dry vacuum pumps excel in tasks such as cell culture media sterile filtering and aspiration, DNA/RNA/Plasmid extraction, vacuum ovens, vacuum filtering, vacuum bag parts forming, sampling, cell harvesters, pick and place operations, package integrity testing, turbidity testing, rice porosity testing, air sampling, and much more.
Key Features:
- Reliable and efficient design for common laboratory vacuum applications.
- Achieves vacuum levels as deep as 5 Torr (29.8" Hg).
- Equipped with a vacuum regulator and gauge for easy adjustment and monitoring of vacuum levels.
- Includes an inlet water trap with a float ball that prevents water ingestion.
- Noise-reduction muffler to minimize sound during operation and filter discharge air.
- Designed for use with dry or aqueous vapor applications only.
- Available in multiple models with free air displacement ranging from 0.4 cfm to 7.1 cfm.
- Ultimate vacuum pressure options and strong pumping speeds maintain performance near expected maximums.
- UL component certification available on select models.
- Integrated motors include thermal overload protection to ensure reliability.
