Filling and Capping Tubes
To prevent spillage and provide support, polycarbonate and polypropylene bottles used in fixed-
angle rotors must be capped when fill levels exceed the maximum level allowed for uncapped
bottles. Bottles should be filled to maximum fill levels when spun at full rated speeds. Unless
specified otherwise, the minimum recommended volume for bottles is half full; this will require
reduced rotor speed for optimum labware performance. Refer to the applicable rotor manual for
bottle fill levels and cap requirements.
Three-Piece Assemblies
Cap bottles with three-piece cap assemblies as follows:
1
Be sure the O-ring, plug, and bottle lip are dry and free of lubrication.
2
Place the O-ring on the underside of the plug.
3
Insert the plug into the neck of the bottle, ensuring that no fluid contacts the O-ring.
4
Tighten the cap by hand.
