Refrigerated water bath with -40°C to +20°C range, 20L volume, ideal for liquid circulation in analytical instruments.
The Lauda RKT20 Refrigerated Water Bath is engineered for precise temperature control in laboratory applications, supporting *liquid circulation* with stable temperature maintenance from -40°C to +20°C. This unit features a 20-liter volume capacity and operates on 220-240 V, 50 Hz power supply, ensuring compatibility with standard laboratory electrical systems.
Designed to facilitate temperature stability in external closed systems, the RKT20 is compatible with a variety of laboratory instruments, including photometers, refractometers, viscometers, polarimeters, and spectrophotometers. This makes it an essential device in research fields such as molecular diagnostics, bioprocessing, and biomedical engineering, where precise thermal conditions impact assay accuracy and reproducibility.
The compact external dimensions of 44 x 40 x 67.5 cm (W x D x H) optimize bench space utilization in busy biotechnology or clinical research labs. The refrigerated water bath contributes critical thermal regulation during protocols like enzyme kinetics, live-cell imaging preparation, and synthetic biology workflows requiring stringent temperature control for reagent stability.
Overall, the Lauda RKT20 supports continuous, reliable temperature control and fluid circulation, making it widely adopted in biopharmaceutical production pipelines and molecular biology research where precision and repeatability in temperature-dependent processes are paramount.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
