2.14 Attachment of Aqua Stop
Aqua Stop can be used to protect the objective
and the nosepiece from liquids.
•
Remove the microscope stage.
•
Put collecting trough 2-38/ 5 ) onto nosepiece
carrier (2-38/ 2 ) and screw it on by means of
two screws 2-38/ 1 ).
•
Screw the objectives to be used into the
nosepiece.
•
Then, use a sharp, pointed scalpel to cut the
holes into cover mat (2-38/
4 ).
Four hole sizes are available that are pre-embossed on the underside of the cover mat and labeled from
inside to outside with hole size number 1 to 4.
The position ID’s of the holes on the mat (1 to 6) correspond to the objective mounts on the nosepiece
(1 to 6).
The objective table below specifies the hole size for the most common objectives that must be cut out
for the corresponding objective.
•
Put cover mat onto nosepiece.
☞
Press down the cover mat only as far as is possible without noticeably slowing down the
motion of the nosepiece.
•
Next, put a silicone ring (2-38/ 3 ) over every objective.
There are two types of silicone rings available: Size 1 – small, Size 2 – large. The objective table also
specifies the size of the silicone ring to be used for the most common objectives.
☞
On objectives with correction ring, the silicone ring must be above the correction ring.
On all other objectives, slide the silicone ring up to about 3 mm before the beginning of the
thicker part of the objective to ensure correct function of the objective’s specimen protection
mechanism.
•
Then, slip the cut drain hose over the two drain connectors (2-38/ 6 ). Put the other end of the hose
into the collecting tank.
☞
The liquid can only drain if the collecting tank provides venting. This is made possible e.g. by a
hole in the lid or by screwing the lid only loosely.
