Product description

Dual stack water-jacketed CO2 incubator with ±0.2°C temperature uniformity, 0–20% CO2 range, 20-gallon capacity.

The NuAire NU-4750 is a dual stack water-jacketed CO2 incubator purpose-built for precise control of temperature and CO2 levels in cell culture and bioprocessing applications. Designed with a 100% stainless steel chamber and a 20-gallon (75.7 L) water jacket capacity, it ensures stable incubation conditions essential in molecular diagnostics, synthetic biology research, and biomanufacturing workflows.

Key technical specifications include:

  • Temperature range: 18°C to 55°C with ±0.2°C uniformity at 37°C
  • CO2 control range: 0% to 20% with ±0.1% accuracy, critical for maintaining cell culture environments
  • Interior dimensions: 21 x 20.5 x 25 inches (W x D x H) with max shelf load of 30 lbs
  • Exterior dimensions: 31 x 25.5 x 34 inches and dry weight of 101 kg (222 lb)
  • Power requirements: 115 VAC, 50/60 Hz, 5A

This incubator is widely adopted in biotechnology laboratories and clinical research facilities for live-cell incubation, cell growth analysis, and biomedical engineering experiments. The water jacket design provides superior thermal stability compared to air-jacketed models, making it critical in bioprocessing pipelines requiring stringent environmental control.

Please note that this specific unit, manufactured in 2000, currently requires diagnosis and repair due to a temperature error and damaged hose connector. The power cord is included; computer interface is not included.

This equipment is essential for researchers and clinical scientists needing reliable incubation for cell culture, gene editing protocols, and molecular biology workflows in environments where precise temperature and CO2 regulation are fundamental.

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.
