The Huber Unistat tango Dynamic Temperature Control System offers advanced thermodynamic properties and a wide range of functions to meet demanding applications. With Unistat technology, users achieve precise, reproducible temperature control, rapid heating and cooling times, and extensive temperature ranges without requiring fluid changes. The self-regulating pump optimizes circulation and flow, while its soft start-up feature protects delicate glass reactors from breakage.
The hydraulically sealed Unistat design significantly extends the service life of the temperature control fluid by preventing oil loss through vaporization and oxidation. Equipped with extensive safety features, the Unistat tango supports unsupervised continuous operation by constantly monitoring relevant operating conditions. In emergencies, the system activates an emergency cooling circuit to maintain process safety.
Unlike conventional systems, the tango employs an expansion vessel with a sight glass instead of a temperature control bath. The expansion vessel is not thermoregulated or insulated, eliminating oil vapor, oxidation, and moisture absorption issues common in other thermostats. This design ensures cleaner and more efficient operation.
The electronic Unistat controller integrates two components: control electronics and an interchangeable control panel. It features a non-volatile memory for storing and recalling status data, an electronic clock for chronological recording, and a programmer for scheduling operations.
The controller displays warnings, disturbances, and messages while locking specific settings during operation to prevent accidental parameter changes. Adjustments to the minimum and maximum set points are only possible when circulation is off, ensuring safe and secure operation at all times.
This Huber Unistat tango is used and reconditioned. Our technicians test all circulators to confirm that it operates properly and to the manufacturer’s specifications.
While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be operated. If the circulator is both heated and cooled, we will perform extended runs at both ends of the temperature range.
Please inform us if you have specific testing requirements or requests. We will gladly work with you to ensure these requirements are addressed during testing.

Yes, all equipment from American Instrument Exchange comes with a warranty.
Used/reconditioned/refurbished equipment is tested to make sure it operates to the manufacturer’s specifications and comes with a 90-day warranty (unless otherwise noted). New equipment comes with a warranty from the manufacturer.
Testing requirements vary across all the equipment categories we sell. Temperature controlled units are tested with NIST traceable probes and data loggers. Gaskets, external housing, glass, handles, controls and control screens are all thoroughly inspected for integrity and functionality.
We test all equipment using the manufacturer's parameters and specifications to confirm that the unit operates properly. While we may not be able to test for specific analytical applications we do our best to simulate the conditions under which the equipment will be used in your lab. If you have particular testing requirements please let us know and we’ll work with you to make sure these are addressed during testing.
We can ship products both nationally and internationally using a well-established network of transporters. Smaller items will ship via UPS. Larger equipment will be palletized and shipped either LTL or air-ride, depending on the specific equipment and/or delivery requirements. In many cases we can offer inside delivery. Customers are also welcome to make pick-up arrangements using their own preferred carrier.
All shipments are FOB Haverhill, MA. American Instrument Exchange will take reasonable steps to protect the equipment during shipment and the equipment will be fully insured. The customer will be charged for all shipping and handling charges, and fees incurred in the process of delivering the order.
For local customers in and around New England we can offer shipping and delivery using a local moving company trained by our staff to handle and deliver lab equipment. Our local movers can provide either standard dock-to-dock delivery or bring the equipment into your lab and set it in place.
Prior to signing the POD (Proof of Delivery), you are responsible for inspecting the goods for any damage. You MUST note any damage on the POD prior to letting the driver leave. This is to protect you, the receiver of the goods in the unlikely event of any damage.
