Compact diaphragm air pump NUP-1 with 12L/min flow, 67kPa vacuum, 0.20MPa max pressure.
Seinēidō Inouchi NUP-1 Compact Diaphragm Air Pump is designed for laboratory applications requiring precise air displacement and vacuum control. Featuring a diaphragm pump mechanism driven by a 25W capacitor motor, this compact air pump delivers a flow rate of 12 L/min with a maximum vacuum level of approximately 67 kPa (500 mmHg) and a maximum pressure of 0.20 MPa (2.0 kg/cm²). The pump’s gas-contact parts are constructed with brass coated in fluororesin to ensure chemical resistance and durability in various laboratory environments. The device supports both suction and discharge functions through a 9 mm diameter port suitable for typical laboratory tubing connections. Operating on AC 100V with 50/60Hz frequency, it includes a 3-meter power cord with a 2P plug for convenience. Its compact footprint of 250×150×160 mm and lightweight design (3.3 kg) make it suitable for benchtop use in biotechnology, molecular diagnostics, bioprocessing, and biomanufacturing workflows where reliable air pumping and vacuum generation are critical. Note: This unit is sold used and as-is; performance may differ from new units, necessitating verification for specialized applications.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
