Hart Scientific 6330 - Compact Bath (35 °C to 300 °C)

When you only need a circulator or utility bath to control a process within a few degrees or to maintain biological test samples, talk to a utility bath manufacturer. But when you’re doing precision thermometer testing, and stability and uniformity are critical to the success of your work, talk to us. 

Hart Scientific has been making the world’s best-performing temperature baths for almost two decades. With our proven heating/cooling designs and hybrid analog-digital controller, Hart baths apply the most effective technologies that are commercially feasible. These four compact baths are no exception. 

6330 

This bath delivers all the high temperatures you need up to 300 °C (572 °F). With stability and uniformity at 300 °C better than ±0.015 °C and ±0.020 °C respectively, calibrations can easily be performed at this high temperature with total uncertainty better than ±0.05 °C. At lower temperatures, stability and uniformity are even better. 

The 6330 is only 12 inches wide and less than 19 inches tall, so it fits easily onto a benchtop without consuming precious space. An optional cart with casters and a storage area raises the 6330 to a convenient height when used on a floor and provides an extra cabinet for lab supplies. With built-in handles, it even lifts easily onto and off of its cart or benchtop. No matter where you want to use this bath—or even if you want to move it around—the 6330 gets there hassle-free. 

7320 and 7340 

Also featuring large work areas, our Model 7320 and 7340 baths cover your needs for low temperature calibrations. The 7320 covers a range from –20 °C to 150 °C and the 7340 reaches even colder temperatures to –40 °C. Below 0 °C, these baths maintain an impressive stability of ±0.005 °C with uniformities better than ±0.006 °C. No utility bath performs as well as Hart’s compact baths below 0 °C or at critical room and body temperatures—or even at important higher temperatures such as 100 °C and 122 °C. 

7380 

For ultracold temperatures, the 7380 reaches –80 °C quickly and maintains a two-sigma stability of ±0.006 °C when it gets there. The 7380 is a true metrology bath, not a chiller or circulator. With uniformity to ±0.008 °C, comparison calibration of temperature devices can be performed with high precision. 

Each bath includes an RS-232 serial interface and our Model 9930 Interface-it software for controlling your bath from a PC. With a Hart Scientific thermometer readout, such as a Black Stack, and our MET/TEMP II software, automated calibrations can run unattended. 

Hart Scientific doesn’t make chillers, circulators, or so-called utility baths, and  utility bath manufacturers don’t make metrology baths. Use the right tools for your work and reap the best possible results. Baths from Hart Scientific are the most stable and uniform of any you’ll find. They’ll give you results no other bath can.
