Packard TopCount Liquid Scintillation Counter
This
instrument counts either dry or liquid samples in a microtitre
/ 96 well microplate
format. In either case you must seal the plate with tape which you
may obtain from Packard Instruments. You may count a single plate in
which case you do not need to use the stacking carriers. However, if
you do count multiple plates be sure to install the loading and
unloading carriers.
Microplate counting
of supernatants from cell mediated
lympholysis assays (CML) is easy and
efficient using TopCount,
a benchtop microplate
scintillation counter.
Samples may be counted with
or without cocktail at efficiencies two to eight
times greater than that obtained by conventional
gamma counting.

A simplified and
faster counting procedure is possible
using a TopCount, a
benchtop microplate
scintillation counter. With
a TopCount
one transfers
supernatants from the assay plate to either
LumaPlates, PicoPlates, or white polystyrene
microplates (e.g., Packard OptiPlates), thereby
retaining the original microplate format
Each microplate
replaces 96 tubes, and the chance
of accidentally rearranging tube or rack order is
eliminated. TopCount�s innovative technology
enables counting of up to 12 samples
simultaneously with an efficiency for 51Cr which
is two to eight times higher than
gamma counting,
depending on the type of microplate used and the
degree of quench.
TopCount has an absolute
counting efficiency for 51Cr of 21%
compared
to 2.7% by multidetector
gamma counting
