DIAGNOSTICA
Instruction for Use for Dispenser 104
for Neo-Sensitabs
Principles
The Neo-Sensitabs cartridges with
spring match the dimension of the
top-plate holes. Each cartridge accom-
modates 50 Neo-Sensitabs.
Pressure applied to the top section will
make the bottom plate move sideways
thus releasing one tablet from each
cartridge. The holes in the bottom plate
ensure that the tablets are placed onto
the agar surface in a pre-determined
pattern.
When using several dispensers, the
colour codes can be used on the top of
the handles.
Intended use
To be used for dispensing Neo-Sensitabs
on agar plates for in vitro diagnostic use.
Intended users
Only to be used by professionals and
people trained to work with microbes
and susceptibility testing.

DIAGNOSTICA
Materials provided
A dispenser as labelled on the container.
Materials required
but not provided
Neo-Sensitabs in cartridges with
spring and other materials necessary to
perform an agar diffusion test.
Components
The Dispensers 101, 102, 103 and 104
for Neo-Sensitabs consist of a top sec-
tion with a handle made of ABS (Acryl-
nitrile-Butadiene-Styrene) and a top lid of
SP (Styrene butadiene). One fixed, one
moving part, two slides/turning plates, all
made of ABS and kept together with a
nylon screw. Colour piece under lid of
PP (polypropylene), springs in stainless
steel and rubber “feet” made of SEBS
(Styrene ethylene butylene styrene).
Models
7 holes: A dispenser adaptable to
8-10 cm petri dishes delivering up to
7 Neo-Sensitabs at a time
(Dispenser 101).
9 holes: A dispenser adaptable to
10 cm petri dishes delivering up to 9
Neo-Sensitabs at a time
(Dispenser 102).
12 holes: A dispenser for 14-15 cm
petri dishes delivering up to 12
Neo-Sensitabs at a time
(Dispenser 103).
16 holes: A dispenser for square
12 x 12 cm petri dishes, delivering up
to 16 Neo-Sensitabs at a time
(Dispenser 104).
Precautions
Only to be used in combination with
Neo-Sensitabs. The dispenser must not
be autoclaved or exposed to ultraviolet
light or radiation. Only to be used with
Neo-Sensitabs cartridges with spring.
Procedure
1. Remove the lids from the
Neo-Sensitabs cartridges
2. Carefully insert the cartridges one
by one through the top-plate holes and
make sure that the ridge on the cartridge
matches the groove on the dispenser.
Avoid twisting the cartridge while
pushing it through to the bottom.
3. When the cartridges have been
inserted properly, place the
Neo-Sensitabs dispenser above the
Petri dish.
4. Dispense the tablets by pushing
the handle down.
5. When pressing down the handle the
tablets will be released and transferred
to the agar surface. If the dispenser is
operated too slowly, the tablets may
tend to stand on edge and perhaps
tumble. This is practically eliminated
when the pressure is applied briskly.
6. Repeat this operation until the
cartridges are empty. Discard the empty
cartridges and replace them by full ones.
Storage
No particular storage requirements.
Cleaning
The dispenser is easy to disassemble
or inside cleaning. Turn over the
dispenser and remove the plastic
screw at the centre of the dispenser.
Observe that the four springs are intact
and are placed correctly. Clean the
dispenser occasionally to remove dust
from the Neo-Sensitabs tablets.
Wipe with ethanol and hot water.
Disposal
Clean the damaged or used dispensers
with ethanol and hot water before
disposing of them according to local
regulations.
