Preparation of sample racks and tubes
When preparing the samples for processing, use only Roche Diagnostics
5-position standard racks and recommended sample tubes with the
URISYS 2400 analyzer.
Different types of sample tubes can be used, but they must have the following
dimensions:
o 13-16 mm diameter
o 100-115 mm height
The types of sample tubes recommended for use with the analyzer include:
o Round-bottomed tubes
o Conical tubes
o KOVA tubes (Hycor Biomedical Inc.)
o Urine Monovette (Sarstedt)
If a syringe sample tube is used, for example Urine Monovette, ensure that the
plunger is at its lowest position. Otherwise, the sample probe may be
damaged.
The analyzer processes urine (including control urine) samples.
Wear protective gloves when preparing samples and placing samples onto the
analyzer.
If the sample contacts the operator’s skin, wash the affected area immediately with
a large volume of water.
Analyze samples within two hours from the time that the urine samples were
obtained.
Do not expose samples to direct sunlight.
Do not add any preservatives to the samples.
Take care that sample material does not contain air bubbles or foam.
If using KOVA-tubes, sample racks need to be equipped with “KOVA-spacers”.
If samples arrive in different containers, transfer them to recommended test tubes.
Use a minimum sample volume of 1.5 ml for round-bottomed tubes, and 2 ml for
conical, KOVA, and Monovette tubes.
