SC475 50ml Digestion Vessel
Traditionally soils, sediments, sludges, foods and other materials have been digested using Aqua regia (a mixture of Hydrochloric acid and Nitric acid) as a preparation for the determination of their trace metals content.
These digestions have in the past been done in glass beakers on a hotplate, however modern standards in laboratories demand a greater level of control and accuracy.
C. Gerhardt UK can offer two solutions for trace metals analysis:
Gerhardt SMA Trace Metal digestion System
This is the ultimate in design and control of digestions for trace metals analysis. Built to comply with European Standard methods including ISO 11466:1995, DIN 38414 and BS 7755-3.9, the system features an aluminium hotBlock for 8 or 20, 250ml glass tubes, water condensers, cold acid traps and accurate time/temperature control.
Gerhardt SMA systems can also be supplied without acid traps for use in Chemical Oxygen Demand (COD) analysis. For more information about the Gerhardt SMA Trace Metal Digestion System - click here.
Environmental Express Graphite Digestion Blocks
The Environmental Express HotBlock provides a convenient way of digesting large numbers of samples. HotBlocks are available to digest 36 or 54, 70ml tubes, 25 or 35, 100ml tubes or 96, 15ml tubes.
Digestions for trace metals are usually at a relatively low temperature and can be done in disposable flat-bottomed polypropylene tubes. Digestions at higher temperatures can be done in flat-bottomed glass tubes.
Condensation is simply done by polypropylene watch glasses.
Optional controllers from simple on off through to fully time/temperature programmable systems are available.
