Precision water bath TR-1A with PID control, float dry-run protection, adjustable flow, and digital timer for biotech and lab use.
The AS ONE TR-1A Thermal Robo is a precision water bath designed for laboratory temperature control applications in biotechnology, molecular diagnostics, and bioprocessing workflows. It features a microcomputer PID controller delivering highly accurate temperature regulation within the range of -20.0°C to +80.0°C, with control accuracy of ±0.05°C. The bath supports a temperature control range from room temperature +5°C up to 80°C (maximum 70°C when using the included polypropylene water tank), making it suitable for live-cell incubation, enzyme reactions, and thermal incubation studies.
Equipped with a float-type dry-run prevention system and a double lock safety circuit from two independent circuits, this water bath ensures enhanced safety to prevent overheating and dry operation. Timer functionality includes both on-timer and off-timer settings from 1 minute to 99 hours for automated process control.
The unit integrates a jet flow stirring mechanism combined with a 1 kW SUS316 stainless steel heater for uniform heat distribution, and a pump capable of max flow 10 L/min with a 1.4 m maximum head. Power supply is AC 100V at 50/60Hz with maximum power consumption of 1.1 kVA.
Compact in size with outer dimensions of 140×150×310 mm and a weight of 3.5 kg, the TR-1A is well suited for benchtop use in biomedical engineering, biomanufacturing quality control, and synthetic biology laboratories requiring precise thermal environments. This pre-owned unit is sold as-is with performance verified to current condition; users are advised to confirm functional specs for critical biotechnology applications such as molecular cloning workflows and clinical diagnostic assays.
This water bath's combination of PID temperature control, safety features, and programmable timers makes it a valuable tool for researchers in cell imaging, bioprocessing temperature maintenance, and fluorescence analysis protocols.
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.
