Using mixing programs
Rotation programs F1, F2, F3, F7
These programs are used to perform mixing of lab-
oratory samples by means of rotation of the rack.
Rotation speed is indicated on
RPM display and
could be changed either during the operation or
when the rack is stopped.
Tip !
Once RPM has been set it will apply to all the pro-
grams in the F menu including customer programs.
Vortexing programs ‘u’ & ‘U’ (Vortexing regimes).
These programs are used to perform intensive mix-
ing of different size test tubes by means of shaking
and vortexing. Vortexing frequency is indicated on
RPM display and could be changed either during
the operation or when the rack is stopped.
During these regimes rack could be manually posi-
tioned under any angle by hand to insure best per-
formance and convenience.
Tip !
Once vortexing frequency has been set it will apply
to all the programs in the F menu that feature shaking
including customer programs.
Tip !
In case of rack loosing its preset position while
vortexing reduce the vortexing frequency until opera-
tion becomes stable.
Angular shaking 6, 8, 10, 15, 30, 45, 60, 90, 99
These programs are performing defined angle and
speed shakes from the vertical initial position. This
kind of shaking is recommended for mixing sam-
ples in tubes bigger then 5 ml volume.
Current angel settings are displayed on F display.
Shaking speed is shown on
RPM display. All the pa-
rameters of angle and speed can be changed either
during operation or when the rack is stopped.
Tip !
In case of rack loosing its preset position while
shaking reduce the shaking frequency until operation
become stable.
Combined programs F4, F5, F6, F8, F9
These programs are performing different combina-
tions of rotation and vortexing.
Current speed is shown on
RPM display and can be
changed either during operation or when the rack
is stopped.
Vortexing frequency can be changed by selecting
on ‘
F’ display either ‘u’ or ‘U’ function and set vor-
texing frequency accordingly.
(see also Vortexing
programs ‘u’ and ‘U’)
Now vortexing frequency is adjusted to the best
performance within current application.
Tip !
Vortexing frequency settings that has been de-
fined in ‘u’ or ‘U’ functions and rotation speed settings
are valid throughout all the programs including cus-
tomer programs.
Customer programs C1, C2, C3
Are used to create customized algorithms of rack
rotation and shaking
(see ‘Creating customer pro-
grams’).
Creating customer programs C1, C2, C3
Introduction
Customer programs consist of a sequence of basic
operations or
steps* that are inputted by operator
to the memory of a mixer. Single program can con-
sist of up to 78 steps and must have its start and
end point in the
initial point**
*step
- Is a single basic operation that is inputted in
the memory by pressing button.
**Initial point
- Initial rack vertical position.
List of steps available for creating customer pro-
grams.
SP
– Rack spinning.
*Clockwise rotation
- Rack rotation clockwise relative-
ly to motor control block.
***Counterclockwise rotation
- Rack rotation coun-
terclockwise relatively to motor control block
PP
- Pause Hold the rack in any defined position for
1.5 sec.
PU
– Shaking Big amplitude U shaking for 1.5 sec. in
any defined position.
Pu
- Shaking Small amplitude u shaking for 1.5 sec. in
any defined position.
P0
– End of program
Tip !
by inputting any of PP, PU, Pu steps more then
one time the duration of this operation increases ac-
cordingly.
