Product description

CO2 incubator with water jacket, 18–55°C, ±0.2°C uniformity, ±0.1% CO2 accuracy, for precise cell culture control.

The NuAire NU-4750 is a water-jacketed CO2 incubator designed for advanced cell culture and molecular diagnostics applications in biotechnology and research. It features a 100% stainless steel chamber engineered to maintain an optimal in-vitro environment with high stability and uniformity.

  • Temperature Range: 18°C to 55°C, with tight uniformity of ±0.2°C at 37°C
  • Temperature Sensitivity: ±0.0125°C, critical for live-cell imaging and synthetic biology workflows
  • CO2 Control: Range from 0 to 20% with ±0.1% accuracy, enabling precise atmospheric regulation essential in stem cell culture and bioprocessing
  • Rapid CO2 Recovery: Returns to 5.0 ±0.2% in under 3 minutes, minimizing experimental downtime
  • Water Jacket Capacity: 20 gallons ensures stable temperature with minimal fluctuations, important in biomedical engineering and molecular cloning environments
  • Maximum Shelf Load: Supports up to 30 lbs per shelf (19.25 x 19.25 inches), accommodating diverse bioreactor vessels and culture plates
  • Dimensions: Interior 21” W × 20.5” D × 25” H; Exterior 31” W × 25.5” D × 34” H
  • Power Requirements: 115VAC, 50/60Hz, 5A, 1-phase

Originally manufactured in the USA (2000), the unit includes power cables and requires refilling the water jacket with de-ionized or distilled water. Current status indicates a need for calibration to correct temperature stabilization approximately 10°C below setpoint, which is critical for maintaining reproducibility in molecular diagnostics and cell biology research.

This incubator is widely used in clinical diagnostics, biotechnology laboratories, and biomanufacturing pipelines, offering stable atmospheric and thermal conditions essential for gene editing experiments, stem cell cultivation, and tissue engineering. Its stainless steel interior and water-jacketed design reduce contamination risks and provide reliable environmental control for experimental reproducibility.

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.
