The TegraDoser-5 dosing system
Adding an automatic dosing system to your
TegraSystem gives you complete control of
the entire preparation process and thus the
quality of your preparation results and the
costs involved.
- Built-in database with 10 preprogrammed
Metalog Guide methods
- Built-in database with up to 200 methods
leaves you in complete control
- Easy programming and large graphic display
- Excellent reproducibility
- Cost saving specimen preparation
- High-quality peristaltic pumps guarantee
exactly the same dosing every time
- No vaporization or spray mist
- Automatic recalculation of method
parameters when exchanged between
different machines
- Automatic dosing of Oxide Polishing
Suspensions
- Configuration according to your needs
Control the quality of your results
Manual dosing always implies certain varia-
tions in the amounts of abrasives and lu-
bricants being dosed, and in the intervals
between each dosing. TegraDoser-5 ensures
that exactly the same amount is dosed each
time – no matter how many times a prepara-
tion sequence is carried out.
But TegraDoser-5 is much more than just a
dosing system. The built-in database can con-
tain up to 200 preparation methods that can
be stored and recalled at any time. This gives
you full control of all preparation parameters
and methods, regardless of which techni-
cian, machine or laboratory performs the
job. Exactly repeatable settings give reliably
reproducible results and frees resources from
routine checks and repeats.
On a large graphical display preparation meth-
ods can easily be programmed and edited,
whereas the method is selected and started
from the TegraPol.
No vaporization or spray mist
The peristaltic pumps on the TegraDoser transport both suspensions and lubri-
cants to the polishing cloth. In other dosing systems the suspension is vapor-
ized and sprayed onto the cloth, resulting in an unhealthy spray mist. With the
TegraDoser the liquid is dosed exactly where you want it on the cloth, improv-
ing preparation quality and improving the working environment.
Control your consumables costs
With the help of TegraDoser the dosing of suspensions and lubricants can be
adjusted to the exact amount necessary for the preparation method in question.
This will result in substantial savings on the consumables account. And Tegra-
Doser also enables the operator to attend to other tasks during the preparation
process – the dosing is automatically taken care of.
Automatic recalculation of preparation methods
A preparation method always needs to be adapted to the disc size of the grind-
ing and polishing machine employed. As an example, the amount of suspen-
sion and lubricant that has to be applied on a 200 mm disc system is much
less than the amount needed for a 300 mm disc system, simply because the
surface area is smaller. The TegraSystem takes complete care of these required
adjustments. Since the TegraSystem automatically detects the connected ma-
chines and units it can also automatically recalculate preparation methods to
fit all system sizes. This ensures that preparation quality and reproducibility is
maintained when preparation methods are being exchanged between machines,
colleagues and labs.
Automatic dosing of Oxide Polishing Suspensions
The use of peristaltic pumps also makes it possible to include the dosing of
oxide polishing suspensions in an automatic dosing unit. No other separate
dosing units offer this feature. In addition, when working with oxide polishing
suspensions, water is automatically applied onto the polishing cloth before and
after the preparation. This ensures that the cloth is prepared prior to the polish-
ing and that both specimens and cloth are cleaned afterwards.
TegraDoser-5 can be equipped with up to 7 peristaltic pumps, 6 for diamond
suspensions or lubricants and 1 for Oxide Polishing Suspensions.
Choose between 3, 4, 5 or 6 pumps for diamond
suspensions/lubricant both with and without the
pump for Oxide Polishing Suspensions
