Bottle And Tube Caps; Aerosolve Canisters - Beckman Coulter Avanti J Series Instructions For Use Manual

Bottle and Tube Caps

The need for caps depends on such factors as the kind of rotor being used, the type of container, and
the amount of sample being centrifuged.
Some tubes must be capped before centrifugation, as in the case of thinwall tubes. The thickness
and strength of some containers, such as thickwall plastic and stainless steel tubes used in fixed-
angle and swinging-bucket rotors, allows them to be run without caps, but they must be only
partially filled. (Refer to the applicable rotor manual for allowable capless fill levels.) When greater
fill volumes are required in these tubes, caps must be used for sample retention.
When closed containers are required, several choices are available:
• Cap assemblies—threaded caps with inserts and O-rings, or one-piece caps with O-rings, that
provide a leakproof closure to accommodate a capacity container load (that is, to the bottom of
the insert).
• Threaded caps without inserts or O-rings—these are not as liquid-tight as the cap assemblies;
therefore, the meniscus must be kept lower to prevent leakage.
• Snap-on caps—these caps are simple to use but are not as liquid-tight as the cap assemblies or
threaded caps. They require an even lower meniscus to prevent leakage.

PN JR-IM-10AG
Aerosolve canisters, used in the JS-4.3 swinging-bucket rotor, are designed to
minimize aerosol leakage and liquid spills. The canister is transparent, enabling
you to see broken labware and take proper precautions before opening the
canister.
The canister and lid are made of polyphenylsulfone, tube racks are made of
polypropylene, and the O-ring is ethylene-propylene rubber. Refer to
APPENDIX A, Chemical Resistances, to determine compatibilities with specific
chemicals.
Each canister can hold a variety of tube sizes in tube racks that are specifically
designed to fit in the canisters. The canister can also be used as a 500-mL wide-
mouth bottle.
WARNING
When centrifuging hazardous materials, always open canisters in an
appropriate blood or biological safety cabinet.
