Micro- and Macro-Kjeldahl Extraction Heaters

Not yet rated

The Micro- and Macro-Kjeldahl Extraction equipment has been designed for Kjeldahl extraction on a micro/macro scale to determine the protein content of food.

These multibank units have 2 or 6 recesses in a stainless steel outer casing with back-mounted brackets (supplied with each unit), which can hold support rods of 12.7mm diameter max. The Micro 6 recess model accommodates flasks of between 18- 50ml only. There are 2 volume sizes available for both the 2 and 6 recess Macro models, one for 100- 300ml vessels and the second for 500-800ml vessels.

Each heating mantle has it own energy regulator incorporating an On/Off switch and a "Mains to Heater" amber neon indicator. There is also a "Mains On" clear neon indicator on the front panel.

The lower part of the unit houses dedicated controllers for each recess. This "cool zone" housing is separated from the heating elements by a stainless steel screen and a well-ventilated air space. The heating element consists of thermally insulated element wire stitched into a cartridge, and operates up to a temperature range of 550°C to 800°C maximum.

The MM Micro-Kjeldahl and all MQ Macro-Kjeldahl Equipment models incorporate an earth screen to protect the user from electric shocks and are double-fused for extra safety (except for the MQ3868B/E which is only available as the 230V model as it is wired in directly). The rugged stainless steel outer casing is durable and easy to clean.
