Product description

High-capacity, programmable Thermo Sorvall X4F Pro floor centrifuge with refrigeration, 15,200 rpm, 25,830 x g for biotech and clinical labs.

The Thermo Scientific Sorvall X4F Pro and X4R Pro refrigerated floor centrifuges deliver versatile high-speed sample processing optimized for biotechnology, molecular diagnostics, and clinical research. Key features include:

  • Maximum capacity: 4L allowing up to 196 blood tubes, 40 x 50 mL conical tubes, or 96 x 15 mL tubes per run, ideal for bioprocessing and cell culture protocols.
  • Maximum speed: 15,200 rpm (up to 25,830 x g with fixed angle rotor), supporting high-resolution separation critical in molecular cloning workflows.
  • Temperature control (X4R Pro model): Refrigerated operation ranging from -10°C to +40°C with precise ±2°C accuracy and pre-cooling to maintain sample integrity during biopharmaceutical production pipelines.
  • Rotor compatibility: Supports a wide range of fixed angle and swing-out rotors including specialized microliter and BioBottles rotors, facilitating synthetic biology and biomanufacturing applications.
  • User interface: Full-color touchscreen controls allow storage of up to 100 customizable programs, including adjustments for speed, temperature, acceleration, deceleration, RCF, and timer settings—enabling repeatable protocols in molecular diagnostics.
  • Safety and convenience: Features SMARTspin technology for rotor auto-detection and imbalance correction, Auto-Lock III push-button rotor locking for streamlined sample handling, and ClickSeal Bucket Sealing System to secure hazardous bio-samples without manual screwing.
  • Drive system: Energy-efficient direct brushless induction motor offers quiet operation with reduced laboratory environmental impact.

These floor centrifuges are designed as freestanding units to conserve benchtop space and are widely adopted in biotechnology and clinical laboratory workflows requiring precise temperature management and high-throughput sample processing. The Sorvall X4 series is essential for researchers performing cell fractionation, blood separation, and synthetic biology assays, providing robust performance aligned with modern bioprocessing and molecular biology demands.

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.
