Lab Vacuum Filtration Pump VP-20PRO, 20L/min, Negative Pressure

Highlights

• 【LIGHT & PORTABLE】Laboratory vacuum pump is compact in design and small in size, making it easy to carry. Non-slip suction cup feet ensure the vacuum pump runs stably and does not shake when working.
• 【PRESSURE ADJUSTABLE】The vacuum pump operates at a speed of 20 liters per minute, with adjustable pumping pressure via a knob, significantly reducing laboratory filtration time. It is suitable for various liquids where gravity filtration alone is excessively time-consuming.VP-20PRO is a Adjustable pressure negative pressure vacuum pump.
• 【OIL-FREE】Oil-free small diaphragm pumps, which means there is no need for regular maintenance and no need to dispose of, or replace, oil, providing clean operation without contamination.
• 【HOW TO USE】The air pump is only suitable for vacuuming, it can't enter liquid. The first step is to fix the complimentary filter membrane in the middle of the rubber tube, the second step is to fix the two ends of the rubber tube to the vacuum pump and the filter unit, the third step does not need to be set up for a one-button start thus getting the best experience.
• 【WIDELY USED】Vacuum pumps provide a reliable source of vacuum for solvent filtration, distillation, vacuum drying, extraction and other experimental steps. Widely used in aerators, nitrogen blowers, solid phase extractors, solvent filters, air samplers and other applications requiring vacuum pressure.
