AutoBlock™ Plus Digestion System
Automated sample prep
for metals digestions
The AutoBlock Plus digestion system automates
sample prep all the way through a final fill-to-volume
step but takes up less space and costs less than
previous models and competing products. Since 1997,
laboratories worldwide have relied on Environmental
Express for dependable, well-engineered equipment
and consumables to simplify and improve the metals
digestion process. This latest generation of AutoBlock
is the most efficient one yet!
The AutoBlock Plus system digests up to 54 samples
simultaneously, adding up to ten reagents, while
controlling sample temperatures and digestion times.
Easy-to-install software comes programmed with
common EPA Methods and records all digestion
procedures and data.
Improved features add flexibility:
Advanced User-Friendly Software. Preprogrammed
EPA Methods including 200.2, 200.7, 200.8, 3050B,
7470.A, 7471, and 245.1 plus an easy-to-use procedure for
creating custom methods. Software runs on a PC, away
from the acidic environment of the digestion process.
Single X, Y, Z Injection Probe. This single probe
automates reagent addition for up to 54 samples. The
AutoBlock Plus unit has 8 reagent and 2 DI water ports.
Final Fill-to-Volume Function. After digestion, the unit
adds deionized water to the digestates to achieve the
final volume you choose.
Flexible Batch Size. Operate any batch size up to
54 samples, providing more economical use of reagents.
Optional Fume Hood. Place the AutoBlock Plus unit in
your existing fume hood or use the optional HEPA-filtered
fume hood to vent into your existing duct work.
Smaller Footprint. The compact unit measures
36"W x 38.5"H x 24"D.
Increased Safety. Leak and pressure detectors minimize
analyst contact with acids.

Getting consistent results and freeing up analyst’s time has never been easier.
The analyst initiates a method and AutoBlock Plus system does the rest.
To operate, the analyst simply chooses a method, loads
samples into the AutoBlock Plus system, and presses the
start button. The dispensing arm with probe robotically
adds the appropriate amount of the specified reagent to
each sample. The samples are lowered into the heated
block and the temperature is held at the desired level for
the allotted time period.
When the procedure calls for additional reagents the
system lifts the samples, turns off the heat, and cools the
samples with HEPA-filtered air. After cooling, the additional reagents are added. The samples are lowered back
into the graphite block, the block re-heats and digestion
continues. When all digestion procedures are complete,
the samples are lifted and cooled. A special probe sensor
determines the level of the digestate in each vessel.
The AutoBlock Plus automatically calculates the volume
necessary and fills each sample to the specified final
volume. A visual alarm alerts the analyst that the
digestion procedure is complete. After each reagent
addition, the entire fluid delivery system is purged with
DI water to flush corrosive reagents from the system.
With the AutoBlock Plus, reagent additions and digestion
intervals are scheduled and timed automatically. This
uniformity in process improves productivity and provides
consistent results. The analyst is free to perform other
tasks and can monitor the digestion progress by viewing
the control screen at any time.
Robust construction ensures
durability and longevity.
All components of the AutoBlock Plus unit are
manufactured to withstand the harsh environment
of the metals lab. Metal components are kept to an
absolute minimum to eliminate corrosion and avoid
sample contamination.
– The AutoBlock Plus features a 54-well
PTFE-coated graphite block in a rugged,
corrosion-resistant casing and utilizes silicone
mat heating technology.
– The guide rod of the reagent dispensing arm is
PTFE coated to prevent corrosion and sample
contamination.
– The AutoBlock Plus cabinet is continually purged
with inert gas, removing acidic fumes that could
potentially cause corrosion.

Superior engineering enhances performance.
– State-of-the-Art Delivery System. Reagent addition and final
fill-to-volume steps are controlled by peristaltic pumps. Delivery
is precise and accurate to <2%.
– Reagent Segregation. The system segregates reagents
containing metals (used in mercury digestions) from the reagents
used in digestions for trace metals.
– Convenient Racking System. Three 18-place polycarbonate
racks allow for convenient loading of up to 54 samples. Racks
with samples are raised and lowered into the wells of the heating
block by a precisely engineered lift system.
– Convenient Venting. The benchtop unit is easily vented via
a 4" duct system. Internal exhaust blowers are controlled
automatically.
Intuitive software is easy to install
and understand.
The AutoBlock Plus software comes programmed with common
EPA methods for metals digestions and automatically performs
all digestion steps; alerts the user of scheduled maintenance
procedures; and records and date/time stamps all digestion data
through final fill-to-volume for easy reference or download to a
PC or other backup device.
– Service Interface Screen provides access to items such as
reagent configuration, temperature calibration, pump calibration,
maintenance schedule, supplies status, and data logging options.
–O
perator Test Screen allows the analyst to select a programmed
method, view the method, start the method, and view progress
as the method is performed.
–M
ethod Creation Screen allows the analyst to easily create
customized methods or modify existing methods.
– Maintenance Tab periodically prompts the analyst to perform
routine maintenance. Default settings can be modified to
customize the maintenance schedule.
–D
ata Viewer Screen displays the recorded data in a .dat file
and allows the analyst to convert the file to other file formats
if desired.
