Welch 1402 DuoSeal Belt-Drive Vacuum Pump with 0.5 HP Motor and Large Oil Reservoir
Product Description
The Welch 1402 DuoSeal vacuum pump is a robust, belt-driven system designed for laboratory applications including large chillers, glove boxes, rotary evaporators, and vacuum ovens. Equipped with a 0.5 HP (0.37 kW) motor operating at a low 525 RPM, it reduces friction and mechanical wear, thereby extending pump life and maintaining lower operating temperatures essential for sensitive biotechnology and molecular diagnostics workflows.
Key features include:
- Pumping speed of 160 L/min (5.6 cfm) for efficient air displacement
- Ultimate vacuum pressure below 0.001 Torr (1×10⁻⁴ Torr, 0.00013 mbar) for high vacuum applications
- A large 1.2 L oil reservoir that dilutes contaminants, optimizing performance in processes such as bioprocessing and synthetic biology research
- Compatible with 13/16 in. I.D. (21 mm) tubing with a 1 to 20 inlet connection
Its durable construction and high-performance characteristics make it critical for biomanufacturing, gene editing, and live-cell imaging setups where reliable vacuum is paramount. The Welch 1402 is widely adopted in biotechnology laboratories for its ability to maintain stable vacuum conditions integral to molecular cloning workflows and clinical diagnostics platforms.
With dimensions of 19 x 11 x 15 inches and weighing 58 lbs, it balances a compact footprint and portability. Powered by 115V, 60Hz, 9.8A, this vacuum pump is a technically advanced solution for demanding laboratory environments.
This pump is delivered with a comprehensive warranty and has undergone rigorous service testing to ensure optimal operation, making it a dependable choice for researchers in biomedical engineering and fluorescence analysis seeking precise and durable vacuum solutions.
