Key Features
- 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.
