- Individual 3-point vessel centering
- Excellent access to all vessels
- Staggered start feature for convenient manual sampling
- Screen saver functionality offers most important information at a glance (stirrer speed, bath temperature, time to next sampling interval, elapsed time, media temperature etc.)
- Wake up functionality to start heating at a pre-programmed time
- Programmable infinity test
- MonoShaft™ system to avoid re-adjustment of immersion depth
- Ultra-fast heating system with excellent temperature stability due to newly designed heat exchanger
- Water diffuser for even temperature distribution
- Vibration absorber to avoid vibration transfer into the USP/EP vessels
- Spring loaded pump assembly to eliminate vibration transfer to the frame work
- Extraordinary safety features for pump and heating system, flow control, digital temperature control, water level sensor, thermo switch, thermo fuse
- DQ/QC, IQ and OQ documents included free of charge
