JOANLAB Oil-free Diaphragm Vacuum Pump Laboratory Filter Pump Portable Negative Pressure Pump Adjustable Pressure Lab Equipment

JOANLAB has launched three portable laboratory vacuum pumps, VP-10L, VP-20Pro, and VP-30Pro. The whole machine is equipped with imported rubber diaphragms, with a running noise of less than 50dB and stable power for long-term operation. The wide voltage AC100-220V is suitable for global laboratory power supply.

VP-10L only uses negative pressure suction; The 20Pro/30Pro supports negative pressure stepless pressure regulation, while the 30Pro has upgraded positive and negative dual air ports, which can be used for both negative pressure suction and positive pressure blowing. The three flow rates cover 10/20/30L/min, and the vacuum degree is gradually increased to meet different filtration needs.

The body is compact and lightweight, equipped with a portable metal handle, anti slip suction cup feet, and double-sided heat dissipation ducts to prevent prolonged high temperatures; The pressure gauge displays the air pressure in real-time and intuitively. Widely adaptable to equipment such as filtration devices, solid phase extraction, rotary evaporator, vacuum drying oven, etc., it is the preferred choice for pre-treatment vacuum matching in chemical and biological laboratories.
