The Grant R4R (UK) is a premium refrigerated circulating bath built for demanding laboratory and industrial workflows. With a temperature range of −30 °C to +100 °C and exceptional stability of ±0.1 °C, it's driven by an advanced circulation pump system and precise microprocessor control. The robust 20 L stainless steel bath allows direct immersion of samples or external apparatus. Three programmable temperature profiles streamline routine procedures, while powerful cooling of up to 900 W (at +20 °C) delivers rapid setpoint attainment even under heavy thermal loads. Its no‑spill front‑drain valve and rugged build ensure clean and safe operation. Quiet performance, optional accessories such as insulated hoses, additional pumps, temperature probes, and Labwise software for remote monitoring and data logging enhance functionality. Ideal for spectrophotometry, crystallization cooling, temperature calibration of sensors, and more.
