Metals Digestion System
Approved
by EPA for methods 3005, 3010, 3050A, 3050B, 200.2 and 200.7 & EPA
mercury preparation method 245.1, 245.6, 245.2, 245.7, 7470, 7471 and
1631
Environmental Express HotBlock™ digestion systems
provide clean, economical efficient digestions.
Made of Teflon®-coated graphite and other non-metallic
materials, HotBlocks eliminate corresponding corrosion and the sample
contamination. HotBlocks have been approved by the EPA as a suitable means
of performing EPA methods including 3005, 3010, 3050A, 3050B, 200.2 and
200.7. The HotBlock is also EPA approved for Mercury prep methods 245.1,
245.6, 245.2, 245.7, 7470, 7471 and 1631.
Because heat surrounds the digestion vessel, less energy
is required than traditional acid digestions with hot plates. Electrical
energy required per sample is reduced by as much as 75%. HotBlocks are
protected from runaway temperatures by the exclusive Safe-Sample™ feature.
In the unlikely event of over-heating, an audible alarm in the HotBlock
sounds and electrical power to the heater mat is interrupted. This prevents
the loss of samples due to boiling.

3 simple steps in samples digestions
Step 1 (Selection of digestion system)
Environmental express HotBlock features large batching digestion,
96 (SC196) sample positions for 15mL sample size
36 (SC100) & 54 (SC154) sample positions for 50mL sample size.
25 (SC150) & 35 (SC151) sample positions for 100mL samples size.
Step 2 (Selection of digestion vessels)
HotBlocks use vessels are molded of clarified homo-polymer polypropylene
assuring higher working temperatures and greater chemical resistance than
the commonly used co-polymer polypropylene. Digestion vessels contain
no detectable background contaminants and do not require acid washing
prior to use. Other vessels for special digestion methods are available
in PFA, Quartz & Borosilicate glass.

Step 3 (Filtering of digested samples)
The
FilterMate S0401 works like a French Coffee press. Simply bring your sample
to volume in the SC475 cup, insert the filter down into the sample, and
remove the detachable plunger. Sample is now ready for analysis or to
be capped for storage.
Stir
Block- 15 Position Stirring HotBlock
When sample agitation is necessary during the digestion process, the SC155
is designed to stir individual samples all at a constant rate. Using a
typical Teflon coated stirbar, the StirBlock can spin the sample at a
set rate between 100-2000 rpm while heating. Originally designed for Hexavalent
Chromium digestions the StirBlock has many applications for the industrial
and biochemical laboratories.
