presence. Levels of buffer and distilled water are
managed by float switches within the main body of
the instrument. When the bottle becomes red on the
VDU screen, it is possible to refill the bottles without
interruption to the current run. There is no fluid sensor
on these two bottles.
Carousel
The carousel is di vi -
d ed into 5 posi tions.
Positions 1, 2 and 3
are hybrid locations
which allow to put
reagent or sample
trays. Positions 4
and 5 are dedicated
only for sample trays. When the hood is open, it is
possible to turn the carousel by hand to simplify
access to each position.

This instrument has two parts: pipetting module
and reading module.
Pipetting Module
This part comprised a pipetting unit
, fluidic system
and carrousel
.
Pipetting unit
The pipetting unit consists of a heated tip sample
probe and a wash station. The heated tip uses a
capacitive liquid level detection system to aspirate
all components required to perform the biological
analysis. This includes the sample, diluent and
reagents. After aspirating the sample and reagent
components into the tip, the tip is heated to reac-
tion temperature and acts as a pre-reaction incuba-
tor. This ensures that the fluids are at reaction tem-
perature before dispensing in to the reaction area.
At the end of dispense, the tip is washed to avoid
carry-over contamination between samples.
Caution
, any fluidic hood opening stops tip motion.
Fluidic system
The fluidic system includes 3 bottles of 5 liters.
One for the PBS wash liquid (BUFFER; order code for
the buffer: B.R.A.H.M.S KRYPTOR BUFFER) used to
wash the tubing system after pipetting. A second
bottle with distilled or deminerialized water used as
liquid system (DISTILLED WATER) by priming before
pipetting and to keep the tubing line in water during
instrument stand by or switch off. A third bottle is
used to collect liquid waste (WASTE). Only the waste
bottle contains a float sensor on the cap to manage
the liquid level and a mechanical sensor for bottle
