Specification Brand : T-stereo BulletPoint1 : 【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. BulletPoint2 : 【FILTER IN SECONDS】Vacuum pump can work at a speed of 30 liters/minute, which can save time in the laboratory filtration session, and is suitable for a variety of liquids that take a long time to filter by gravity alone.VP-30L is a positive and negative pressure vacuum pump, which can either pump or blow air. BulletPoint3 : 【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. BulletPoint4 : 【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. BulletPoint5 : 【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.
