Oil-free: The vacuum pump use 0.08 MPa oilless small diaphragm pumps, which do not require oil treatment, replacement, or monitoring. The operating environment is cleaner and suitable for most laboratory work. Efficient: Compared to using gravity for filtration, our vacuum pump operates at a speed of 10 L/min, greatly reducing experimental time. Stability: The vacuum pump is equipped with four shock-absorbing silicone pads, which can be firmly fixed on the workbench to prevent the machine from shaking. The air outlet is also equipped with a noise reduction device to reduce noise, allowing our vacuum pump to operate quietly and stably. Portable: The vacuum pump adopts a compact design, which is lightweight, compact and easy to carry.
