Grant Instruments Optima Heated Circulators
are part of the Optima series, designed for laboratory applications that require precise temperature control, such as heating, cooling, and temperature regulation in water baths, tanks, or external applications. These heated circulators are ideal for scientific research, material testing, and quality control, offering reliable, accurate, and efficient solutions for temperature-sensitive experiments.
The Grant Optima heating circulating range consists of four models – two general purposes: T100 and TC120 and two advanced models: TX150 and TXF200. Combine any of the four models with a Grant stainless steel or plastic tank or with a T-Clamp to attach to virtually any vertical-sided tank. A cost-effective range of multi-purpose systems combining Grants legendary quality and reliability.
