Digital Fisher Scientific Isotemp 220 water bath with 20L capacity, ±0.5°C stability, ambient–100°C range, ideal for biomedical use.
The Fisher Scientific Isotemp 220 Digital-Control Water Bath delivers precise temperature regulation with a range from ambient to 99.9°C and stability of ±0.5°C, making it well-suited for biomedical, pharmaceutical, clinical, and industrial laboratory applications. This benchtop water bath features a 20-liter capacity with internal dimensions of 18 x 10 x 5 inches, providing ample space for samples requiring uniform heat exposure.
Constructed with temperature-resistant plastic and a corrosion-resistant exterior, the Isotemp 220 ensures durability and safety within busy laboratory environments. Its low-profile design facilitates safe operation, while dual thermostats prevent temperature runaway, ensuring stable and reliable performance. The reservoir’s rounded corners allow for easy cleaning and maintenance.
The water bath includes a gabled acrylic lid that reduces condensation and provides clear visibility for monitoring live-cell cultures or molecular biology samples. The integrated digital temperature controller displays readings in either Fahrenheit or Celsius on a large, easy-to-read screen, supporting precise temperature management critical for applications such as molecular diagnostics, bioprocessing, and synthetic biology research.
This model runs on 8.5A, 120V power at 50/60 Hz and weighs approximately 23 pounds, making it a portable yet robust solution for laboratories focused on biotechnology workflows, clinical diagnostics, and biomanufacturing processes. The Isotemp 220 water bath is widely adopted in molecular cloning workflows and essential in biomedical engineering laboratories requiring stable heat incubation environments.
Designed to meet the rigorous demands of modern laboratories, the Fisher Scientific Isotemp 220 water bath supports precise temperature uniformity and is critical in biotechnological applications including live-cell imaging, fluorescence analysis, and molecular biology research.
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.
