Product description

Oil-free diaphragm vacuum pump N86KN.18 with 6 L/min flow, 10 kPa abs, ideal for contamination-free gas handling.

The K.F Lab Diaphragm Vacuum Pump Model N86KN.18 is an oil-free, contamination-free pump optimized for clean gas handling in laboratory and biotechnology applications. Certified with the CE mark, this compact vacuum pump delivers a maximum flow rate of 6 L/min and reaches an ultimate pressure of 10 kPa absolute, making it suitable for sensitive molecular diagnostics and bioprocessing workflows requiring precise vacuum control.

Technical Highlights:

  • Oil-free diaphragm mechanism ensures no contamination, critical for synthetic biology and biomanufacturing labs.
  • Pump head constructed from PPS (Polyphenylene Sulfide) and diaphragm from EPDM, providing chemical resistance and durability.
  • Valve made from FKM (Fluoroelastomer) enhances reliability in handling diverse gases.
  • Built-in thermal protector safeguards pump against overheating during extended runs.
  • Compatible with 4 mm inner diameter tubing for straightforward integration into vacuum lines.
  • Power requirements: AC 100 V, 50/60 Hz, 70 W, 1.8 A align with standard laboratory electrical setups.
  • Compact size (16.4 × 9.0 × 14.1 cm) and low weight (1.9 kg) allow flexible deployment in benchtop environments.

This vacuum pump is widely adopted in biopharmaceutical production pipelines and molecular cloning laboratories where contamination-free vacuum is essential. Note that this unit is sold as a used item and may not perform to new equipment specifications; verification of performance prior to critical applications is recommended. This diaphragm pump is ideal for live-cell imaging setups and cleanroom biotechnology applications demanding reliable, oil-free vacuum generation.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
