Product description

Mechanical gravity door coordinator ensuring coordinated closing of double doors without electrical components.

The COR9G Gravity Door Coordinator is a mechanical device specifically designed for coordinating the sequential closing of double door systems. This gravity-operated door coordinator ensures one door closes before the other, effectively preventing damage and enhancing door functionality in laboratory and cleanroom access points.

Key technical features include:

  • Model: COR9G
  • Mechanical Coordination: Uses gravity mechanism—no electrical power required, ideal for secure door management in research and biotechnology facilities
  • Components: Includes mounting hardware and detailed installation instructions for straightforward setup
  • Application: Widely used in laboratory entrances, clinical diagnostics environments, and biomanufacturing cleanrooms where controlled access and protection of sensitive areas are critical
  • Durability: Robust design supports frequent operations common in molecular biology labs and bioprocessing suites requiring reliable double door coordination

This door coordinator plays an essential role in facility infrastructure by maintaining environmental integrity and ensuring smooth operation of double doors, integral to biotechnology workflows involving contamination control, live-cell imaging labs, and synthetic biology research facilities.

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?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
