II. Product Set-Up:
Place the rotator on a clean and stable surface.
(Ensure that there is at least 3 inches of open
space 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.
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.
0.5 and 50ml Tubes
Attach the large tube
holder directly to the
rotator (without posts.)
Insert the holder 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 (similar to diagram
above).
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. (When mixing 15 and 50ml
tubes, always load a similar quantity of tubes
on each side of the rotational axis.)
IV. Product Operation:
R2020

The speed of the R2020 is fixed (not

switch to the on position to start the rotation.
When mixing is completed, press the switch

Set the Rotational Speed:
The rotational speed can be selected by
pressing the up and down keys to adjust the

70rpm)
Choose the Mixing Mode:
The R2024 offers three additional mixing
modes, Mix, Pause and Rock.
