eVol® BENEFIT |
| Standard
Preparation |
Standards prepared
in a large volume
flask. From
this
standard aliquots are
individually dispensed
into autosampler vials. |
Standards are made
up directly in the
vial,
including the
make up solvent. |
• Less glassware
usage
• Reduces waste fluid
•
Significant time
saving
• Improved accuracy
and
reproducibility |
| Addition of
Standards |
Small amounts of
standard aspirated
and dispensed
into all
samples before being
transferred to an
autosampler vial. |
One aspiration
and a fast series of
repeated
accurate
dispenses directly
into vials. |
• Significant time
saving
• Improved accuracy
and
reproducibility |
| Delivery of
derivatization
agents |
Laboratory staff
required to work in
a fume hood
with
potentially hazardous
materials, to prepare
combinations of
derivatization agents
in open vials. |
Process completed
with eVol®
programmed to
aspirate an amount
of solvent or agent
and then dispense
aliquots into sealed
vials, Single handed
operation. |
• Improved operator
safety, lower spill
and splash
risk
• Ergonomic benefits
behind fume hood
screen
• Improved accuracy
and reproducibility
• Less glassware
use |
| Serial dilutions |
Transfer of a small
amount of solution
to another
container.
Solvent added to
achieve the required
volume. This is
repeated multiple
times to obtain the
required final accurate
concentration. |
One aspiration of
the solution can be
dispensed
directly
into the solvent
to achieve the
required
accurate
concentration. |
• Complete workflow
simplification
• Significant
time
savings
• Improved accuracy
• Less solvent
required
• Less glassware used |
