Foss – Digestor™ 2508 and 2520
Free up time for other tasks with fully automated digestion. Convenient, safe and flexible operation backed by data and application logging.
2501 Scrubber Unit
For Kjeldahl digestions the 2501 Scrubber Unit should always be considered for safe and efficient neutralisation of corrosive gases. This replaces the water aspirator, supplied as standard.
Exhaust manifolds
All models are delivered with a tube rack with integrated heat shields. They should always be combined with a matching exhaust manifold designed for each Digestion Unit facilitating fume removal, or reflux head and test tubes – 100 ml, 250 ml or 400 ml volume.
Software
Auto systems have memory for up to 127 FOSS Applications and 127 User Applications. There are currently more than 80 FOSS applications in the CD Library supplied.
