DISPOSABLE
CENTRIFUGE TUBES, 50ml
Tubes made of either polystyrene or polypropyleneThese
centrifuge tubes are also useful for collecting and
transporting biological specimens. Leakproof characteristics
are ensured by a flat top plastic screw cap with an
inner sealing lip. Tubes are made of translucent polypropylene
or optically clear polystyrene with molded graduations
from 2.5 to 50ml. Polypropylene tubes can be autoclaved
and will resist temperatures up to 121°C; they will
also resist acids, solvents and alkalies at room temperature.
They withstand centrifugation speeds of 3000 g or 5000
RPM. Polystyrene tubes can tolerate aqueous solutions
of mild bases or weak acids, but not organic solvents,
aromatic or chlorinated hydrocarbons, and they cannot
be autoclaved. They withstand centriguation speeds up
to 1000 g or 1500 RPM.
Tubes are available in bags or in break-away polyfoam
racks for better protection during transport, storage
and for convenient laboratory use. Racks can hold up
to 25 tubes; tube contents are visible from top to bottom
since racks are provided with viewing slots. They are
supplied sterile with green caps or non sterile with
yellow caps.
