2nd detector PMT that intensifies and measures the signal
from the rear emission channel
Note! the detector has a normal side window
PMT used for both photon calculation and
analog mode. The 2nd detector is needed in
dual label measurements (e.g. Eu/Sm) or in
fast FP measurements, where both
polarization directions are measured
simultaneously.
2nd detector emission
light selector mirror slide to select whether the 2nd detector
module handles emission light excited from
above the sample or the bottom measuring
emission light from the emission cable
alphascreen this term is used to cover both the standard
AlphaScreen and HTS AlphaScreen options
when referring to features that are common to
both
alphascreen option separate option including a laser, light guide,
mirror module, filter and plate cooler for
AlphaScreen measurements
Note! AlphaScreen is a measurement
technology based on the use of coated beads.
Donor beads are excited by laser light. Energy
is transferred to bound acceptor beads which
then emit light
aperture hole through which radiation may pass
Note! There are three apertures: for 1536, 384
and 96-well plates respectively. These are for
Ultra Sensitive luminescence . See also shutter

aspiration tube tube between the liquid reservoir and the
syringe in the dispenser . Used to aspirate
liquid from the reservoir or retrieve liquid to it
