THx000 Series Digital Immersion Circulator Descriptions

The Ratek THx000 range of immersion circulators from Ratek offers comprehensive temperature control solutions designed to meet diverse laboratory requirements while maintaining the simplicity and legendary reliability that defines Australia's leading laboratory equipment brand. From the entry-level TH7000 to the fully programmable flagship TH8500, every model incorporates accurate digital PID control technology to ensure precise thermal management across a wide spectrum of applications.

This enhanced range introduces numerous advanced features including an adjustable mounting system with retort capability, adjustable high-flow pump technology, and dual-line digital displays for improved monitoring and control. Enhanced accuracy and stability performance is complemented by a simplified user interface that streamlines operation while maintaining the sophisticated control capabilities required for demanding laboratory environments. These improvements ensure that each model delivers exceptional performance tailored to specific application needs while upholding Ratek's commitment to reliable, user-friendly laboratory instrumentation.

The Ratek TH7000 provides comprehensive temperature control capabilities ideal for applications where external pumping is not required, delivering reliable performance through its intuitive full digital PID control system that ensures accurate and stable temperature maintenance. The integrated high-flow circulating paddle promotes excellent temperature uniformity throughout larger bath volumes, making it suitable for demanding laboratory procedures requiring consistent thermal conditions. As Ratek's entry-level immersion circulator, the TH7000 combines affordability with professional-grade performance, effectively meeting the needs of applications where temperature stability is paramount while maintaining the user-friendly operation that characterizes the entire THx000 series.

The Ratek TH7100 delivers exceptional temperature uniformity through straightforward operation, featuring a high-flow dual outlet pump system that maintains consistent temperatures even in the largest bath configurations. The adjustable flow rate capability allows precise circulation control to match specific application requirements, while the advanced digital PID control system ensures accurate and repeatable temperature results. This combination of powerful pumping performance and precise control makes the TH7100 ideal for applications requiring both extensive circulation and reliable temperature stability.

The Ratek TH7300 is engineered for applications requiring extended temperature ranges, capable of controlling temperatures from -30°C with appropriate cooling systems up to +150°C in suitable media. The high-flow pump system delivers excellent temperature uniformity throughout the bath, while the intuitive full digital PID control ensures accurate and stable temperature maintenance across this broad operational spectrum. The unit features a low watts-density heating element specifically designed for compatibility with silicon oil and ethylene glycol-based heating media, making it ideal for specialized applications requiring alternative heat transfer fluids and extreme temperature control.

The Ratek TH8000 immersion heater circulator delivers precision temperature control through its large, user-friendly dual-line interface, achieving exceptional stability of ±0.04°C when used in Ratek insulated tanks. The unit incorporates a powerful adjustable 17 L/min pump with dual outlets to accommodate external pump-out requirements while maintaining uniform temperatures throughout even the largest bath configurations. This combination of precise control, robust pumping capability, and intuitive operation makes the TH8000 ideal for demanding applications requiring both external circulation and superior temperature stability.

The Ratek TH8200 immersion heater circulator offers precision temperature control through its large, user-friendly dual-line interface, delivering exceptional stability of ±0.02°C when operated in Ratek insulated tanks. Equipped with a powerful adjustable 17 L/min pump featuring dual outlets, the unit accommodates external pump-out applications while ensuring uniform temperature distribution throughout even the most extensive bath systems. This advanced combination of superior precision control, high-capacity pumping, and intuitive operation makes the TH8200 ideal for critical applications demanding both external circulation capabilities and outstanding temperature accuracy.

The Ratek TH8500 immersion heater circulator delivers precise temperature management through sophisticated ramp/soak capabilities. Users can configure up to 9 programs containing 288 total segments, enabling comprehensive customization of temperature profiles. Offering exceptional temperature stability within +/- 0.02°C when used in a Ratek insulated tank, the TH8500 incorporates a robust adjustable 17 L/min pump that maintains consistent temperatures throughout even the most expansive bath systems.
