These Kjeldatherm block digestion systems use an energy efficient aluminum block to heat the digestion tubes. The block is insulated to retain heat and has cutout holes for the digestion tubes. An aluminum insert rack with built-in heat shield and inspection window provides easy, safe observation of the samples.

The block system features overtemperature protection and an excess current switch. The exhaust system has heat-insulated handles and an integrated glass exhaust manifold, allowing safe handling of the exhaust system and digestion tubes separately. With the manual digestion systems, handling of the insert rack and manifold is manual; the automatic digestion systems use a motorized system to lift the insert rack and manifold.

What’s included: two-tier console, insert rack, digestion tubes (quantity and size depends on the system; see table below), and exhaust system. A temperature controller is required; order separately.
