Product description

Set of centrifuge tube racks compatible with 15mL, 50mL, and 250mL tubes, designed for lab centrifuge organization.

This Kubota 5691 centrifuge tube rack set comprises several specialized racks and holders designed for efficient organization and handling of centrifuge tubes and bottles across multiple volumes:

  • Tube Racks:
  • 15 mL conical tube racks (model 055-4780), each holding 32 tubes, includes 2 racks.
  • 250 mL bottle racks (model 055-4850), includes 3 racks.
  • 50 mL tube racks (model 055-4790), each holding 8 tubes, includes 2 racks.

This equipment set is *used* and sold *as-is*, with potential variance in performance compared to new conditions. The racks accommodate multiple tube sizes commonly used in biotechnology, molecular diagnostics, and bioprocessing workflows, making them suitable for organizing samples in clinical diagnostics and research labs. The modular design facilitates effective storage during centrifugation, optimizing space while preserving sample integrity.

Ideal for laboratories requiring versatile and space-efficient tube arrangement, this set supports smooth sample handling in diverse biomanufacturing and synthetic biology applications.

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.
