both in front of and behind the instrument.) Plug
the instrument into an outlet of the appropriate
voltage.
III. Tube Holder Installation / Exchange:
The instrument includes an assortment of tube
holders and posts.
ALWAYS attach the tube holder load tubes outside
of the incubation chamber. Once fully loaded, then
load the posts with tube holders onto the rotating
axis. Loading tubes and tube holder within the
incubation chamber may result in the dropping of
tubes and spillage on the heating surface.
1.5/2.0, 5, 7, 10 and 15ml Tubes:
Attach the tube holders (above) to the included post
with two arms. Press holders on firmly to prevent
them from coming loose during use. Once pressed
on firmly, attach the post to the rotator by inserting
the post into the left side of the rotator first and then
into the main body (right side). Once inserted, rotate
the post until it is fully installed, see below:
To adjust the angle of which the tubes rotate, simply
rotate the position of the tube holders by hand until
the desired rotational angle is achieved.

To rotate tubes horizontally (rolling/hybridization
motion), first attach the 2 small posts to the center of
the large tube holder. (One post has a small flat that
can be inserted to correspond to the flat located in
the center of the tube holder). Thread the 2 posts
together by turning the post (without flat) clockwise
until fully tightener. Then insert posts into the
rotator as described above.
To load test-tubes, press them firmly into the
appropriate holder. ALWAYS ensure a balanced load
across both sides of the rotational axis.
