Using <strong>Tubes</strong> <strong>and</strong> Accessories<br />
FILLING OPEN-TOP TUBES<br />
OPEN-TOP POLYALLOMER TUBES<br />
Open-top polyallomer tubes are used in swinging bucket <strong>and</strong> fixed<br />
angle rotors.<br />
Swinging Bucket <strong>Rotors</strong><br />
Fill all opposing tubes to the same level.<br />
• Thinwall <strong>Tubes</strong>—Fill to within 2 or 3 mm of the top for proper<br />
tube wall support.<br />
• Thickwall <strong>Tubes</strong>—Fill at least half full.<br />
Fixed Angle <strong>Rotors</strong><br />
Fill all opposing tubes to the same level.<br />
• Thinwall <strong>Tubes</strong> —Must be completely filled; liquid <strong>and</strong> cap for<br />
support of the tube wall is critical.<br />
• Thickwall <strong>Tubes</strong>—Can be partially filled <strong>and</strong> centrifuged as<br />
indicated in the applicable rotor manual. Speed reductions may be<br />
required for these partially filled tubes. For greater fill volumes<br />
<strong>and</strong> faster speeds, tube caps should be used. Refer to the applicable<br />
rotor manual for fill volumes <strong>and</strong> speed limitations.<br />
OTHER OPEN-TOP TUBES<br />
Open-top tubes of other materials can also be used in fixed angle<br />
<strong>and</strong> swinging bucket rotors. (Vertical tube <strong>and</strong> near vertical tube<br />
rotors use only OptiSeal or Quick-Seal tubes.) Fill these tubes as<br />
indicated below.<br />
