reagent A composition of chemicals used to determine
the concentration of substances.
reagent bottle Standard plastic bottle for photometric
reagents.
reagent disk The removable device into which the
reagent bottles are placed.
reagent disk position One of the multiple positions
on the reagent disk.
reagent port Section of the analyzer unit where
reagent bottles are inserted and removed.
reagent set Up to three reagents may be required to
perform a certain test. These reagents are handled in
reagent sets. Whenever you remove or replace a reagent,
you do so for all reagents of the set. Each diluent or
cleaner bottle is treated as a separate reagent set.
reference electrode See ISE Reference Electrode.
reference range See expected range.
reference solution See ISE Reference Solution.
repeat The performance of the same test on a sample
again with identical dilution.
reportable range The range of results that can be
reported for the assay. It stretches from the lower
detection limit to the high end of the calibration curve.
request See order.
rerun The performance of the same test on a sample
again with a different dilution.
result The value reported by an analytical device during
or after the assay of a sample or control.
ROM Abbreviation for read-only memory.
Semiconductor memory devices used in computers.
ROM content remains when a computer is switched off.
rotor Assembly consisting of cuvette ring and plastic
frame.
sample area Area on the analyzer where sample tubes
are placed.
sample cup A small container that is used for samples
and also for calibrator and control material. A sample
cup can be placed either directly on the sample area, or
on sample tubes. Compared to a sample tube, a sample
cup allows the use of smaller liquid volumes and so
reduces the dead volume.
sample ID A set of alphanumeric data that
unmistakably identifies a particular sample within a
whole organization. It is used on barcodes and is the
unique identifier used to communicate with a laboratory
information system.
sample splitting The act of making one or more
aliquots from a primary or secondary specimen.
sample tube A glass or plastic container for liquid
samples to be used with the system. It may or may not
have a bar code label, which may be used for positive
sample identification. A sample tube contains sample of
one specific specimen (sample) type.
sample type A type of sample that can be analyzed.
sampling stop An alarm level that indicates a problem
with the sampling system.
See also S.Stop.
scan See barcode scan.
scroll The action of moving through text or graphics
(up, down, left, or right) to see parts of the file or list that
cannot fit on the screen.
scroll arrow An arrow on either end of a scroll bar that
you use to scroll through the contents of the screen or list
box.
scroll bar A bar that appears at the bottom or right
edge of a screen whose contents are not entirely visible.
SD Abbreviation for standard deviation.
secondary tube A sample container of variable size
into which aliquots are transferred.
set See reagent set.
shutdown The process of powering off an analyzer.
