20L Lab Companion circulating bath with precise temperature control up to 150°C, ideal for bioprocessing and molecular diagnostics.
The Lab Companion CW3-20 is a benchtop circulating water bath designed for precise temperature regulation up to 150°C within a 20-liter capacity chamber. This thermal circulator offers uniform heat distribution through its efficient circulation system, critical for applications in biotechnology, molecular diagnostics, and synthetic biology workflows requiring controlled thermal environments.
Key features include:
The CW3-20 is widely adopted in synthetic biology research and molecular biology protocols that demand stringent temperature control and robust fluid circulation. It supports critical workflows in biotechnology, including bioprocessing scale-up, enzyme kinetics testing, and cell imaging sample preparations.
This circulating bath is compatible with various accessories to customize functionality, enhancing its utility in advanced research environments focused on precision temperature management.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
