JOHN Morris Scientific has announced Julabo's new HT Series High temperature circulators capable of rapid temperature control from +20°C to 400°C.
The HT Series offers extraordinarily fast heat-up, and with the optional water cooling unit an almost instant response to exothermic reactions.
Recommended for applications using jacketed reactors and autoclaves, and distillation columns, as well as laboratory, miniplant and process-scale applications.
The self-optimising controller (ICC - intelligent cascade control) ensures high temperature stability; whilst the classic PID control parameters are available at the touch of a button for modification at any time.
In addition, these instruments are completely sealed, preventing the release of burning oil fumes into the laboratory, as well as oxygen into the oil. This eliminates both potential flash situations and oxidation of the oil thus conserving and extending the life of the oil.
Automatic air-purge allows easy filling; and the automated heat-up feature adjusts to external systems.
Other features include a Multi-Display (LED) and interactive LCD display (with resolution of 0.01°C for the entire temperature range); on-line communication via built-in RS232 interface; standby input for emergency switch-off; and ATC function for simple correction of temperature variations.
