System overview

Note: This manual describes all the features of Wallac 1420. Some versions of the
instrument do not have one or more of these features. You can ignore the parts of this
manual not relevant to the version of Wallac 1420 you have.

Wallac 1420 multilabel counter is a complete platform for quantitative detection of light-
emitting, or light absorbing markers.

Depending on the model of the instrument you have

, it

is suitable for flash or glow luminometry, fluorometry, fluorescence polarization, high-
sensitivity time-resolved fluorometry, homogeneous time-resolved fluorometry (LANCE
option) and photometry. It is a compact bench top unit with features such as dispensers,
shaking, temperature control, top or bottom reading and scanning. The software is a 32-bit
application running under Windows



2000 or Windows XP. Up to 1536-well plates can be

counted (depending on the technology and model) as well as Petri dishes, slide filters and
Terasaki plates. Plates can be loaded manually or with stackers for automatic operation.
Output can be to a file on the PC and/or to a laser printer. The following figure shows the
Wallac 1420 system with its PC and laser printer.

If the dispenser unit is connected to Wallac 1420 it looks as follows:
