Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
ColiRollers™ Plating Beads offer a better way to
perform a routine procedure-plating bacteria.
Typical plating methods use a bent glass rod
"hockey stick," which must be immersed in
70% ethanol and flamed between uses, or
disposable plastic applicators. Both require
vigorous spreading while rotating the plate.
These older methods can become extremely
laborious and time consuming when processing
many samples, and can produce inconsistent
results due to differences in pressure applied,
length of rotation time, and moisture content
of the plates. In addition, an open flame can
present a safety hazard. Novagen ColiRollers
Plating Beads are specially treated glass beads
that do the work for you. Simply pipet the
cells on the plate, add 10 to 20 beads, and
move the plate back and forth a few times.
The rolling action of the beads gently spreads
the cells evenly and completely over the agar
surface. Entire stacks of plates can be processed
at one time. After plating, shake the beads
off the plate and the plate is ready for the
incubator. Use of ColiRollers beads eliminates
the inconsistencies of conventional "hockey
stick" methods, and provides even distribution
of colonies every time.
ColiRollers beads are provided sterile and
each package contains enough beads for 60 to
80 plates.
