AS ONE EWS-100RD Digital EC Water Bath Stirrer with PID Temperature & Speed Control

The AS ONE EWS-100RD is a digital EC water bath stirrer engineered for precision temperature control and reliable stirring in laboratory workflows. Featuring a microcomputer-based PID feedback mechanism, it maintains stable rotation speeds adjustable between 100 and 1500 rpm in 10 rpm increments, essential for uniform sample processing. The temperature can be precisely set from room temperature plus 5°C up to 95°C with 0.1°C resolution, monitored via a Pt100 Ω resistance thermometer sensor. Constructed from durable NORIL engineering plastic, the bath offers exceptional strength, heat resistance, and chemical durability, suitable for bioprocessing, molecular diagnostics, and synthetic biology applications requiring temperature-sensitive reaction conditions.

Key technical specifications include a 750W nickel-plated stainless steel heater, stainless bath (SUS304), AC motor drive, and built-in safety features such as over-temperature cutoff with automatic heater shutoff and overcurrent protection. The compact benchtop design (240×280×220 mm) weighs approximately 3.4 kg, supporting laboratory efficiency and space-saving needs. Ideal for live-cell imaging preparation, cell culture stirring, and other temperature-controlled biomanufacturing processes, the EWS-100RD also includes a stirring bar (φ8×30 mm). Users should employ containers with a maximum diameter of 110 mm when stirring samples directly without a rack to optimize performance.

This unit is sold used as-is; potential buyers should verify functional performance aligned with intended molecular biology and clinical diagnostics workflows. Widely used in biotechnology research requiring precise temperature and stirring control, the EWS-100RD is a dependable choice for labs engaged in gene editing and bioprocessing protocols.
