Manual Uranalyze Reader
1. Introduction
®
Welcome and thank you very much for choosing our Uranalyze Reader
analysis.
®
®
The Uranalyze Reader is a reflexion photometer for the analysis of Uranalyze
test strips from NOVASSAY. The measurements are carried out under
standardized conditions. Results may be displayed, printed and sent to a
computer. Instrumental evaluation eliminates potential sources of error inherent
to visual evaluation. Results will not vary due to subjective color perception or
different light sources. Additionally, errors resulting from manual result
administration are avoided. Featuring a clear touch screen and intuitive user
®
guidance, the Uranalyze Reader is ideal for quick, efficient and comfortable
work.
1.1 Technical description
The test strips is placed on a measuring slide with inbuilt reference pad, which
is moved into the instrument along a fixed measurement head. While moving in
and out of the instrument, the test strip is measured reflectometrically. A predefined light source illuminates the test pad. A detection unit then measures the
intensity of the reflected light at three different wavelengths. From this
information, remission values are calculated. The timing of the measurements
may vary depending on test strip and parameter. Using the remission values,
the instrument can, in contrast to visual evaluation, show continuous values
within the respective tests’ measuring range. Once the result has been
determined, it is displayed on the screen, printed and sent to the instrument’s
interface.

2. Safety precautions
2.1 Protective clothing
®
Using the Uranalyze Reader may entail handling chemicals and/or dangerous
substances. In such cases, adhere to the safety measures provided within the
test strip instructions, the in-house regulations of your place-of-work as well as
to good laboratory practice. If in doubt, we recommend to wear at least gloves,
safety goggles and a lab coat.
2.2 Power connection
To ensure safe functioning of the instrument, only use the included power pack.
2.3 Housing damage
If the housing is damaged, the instrument needs to be repaired. Correct
functioning and measurement results cannot be guaranteed anymore.
2.4 Cable break
In case of a broken cable, immediately stop using the instrument and replace
the cable and power pack.
2.5 Improper use
®
®
The Uranalyze Reader instrument is solely designed to read Uranalyze test
strips. Any other usage of the instrument is neither tested nor approved. In the
event of improper use, any claim with regards to warranty and liability are void
and of no effect.
2.6 Transport
To transport the instrument, the cardboard box from the initial shipment
including the protective foamed plastic is well suited. Therefore, we recommend
to keep the box. In case you do not have the original box anymore, use a large
cardboard box and plenty of soft cushioning material, so that the instrument
cannot shift during transport.

3. Instrument set-up
3.1 Set-up location
Only use the instrument in a suitable location. It should be positioned on a dry,
clean, level, hard and horizontal surface. The operating temperature is between
5–40 °C, while the optimal temperature range for the instrument is between 18–
25 °C. For optimal performance, the humidity should be between 20–80 %.
Make sure to protect the instrument from drastic changes in temperature. Avoid
positioning the instrument close to windows, hot plates, ovens etc. To ensure
correct functioning and reliable results, the instrument should not be exposed to
direct sunlight or other bright, focused light sources.
If the instrument underwent drastic temperature changes (e.g. during transport
of shipment), it should not be operated prior to sufficient acclimatization. Also,
we recommend not to use the instrument close to electrical fields (e.g. micro
wave ovens, radio units etc.), as it may affect measurements.

13.11 Reaction time
In the "Reaction time" menu, you can decide whether the instrument will wait for
the strips reaction time before starting a measurement. By default, the reaction
time is enabled. The reaction time is then shown as a progress bar once the
strip is placed on the strip holder.
If you disable the reaction time, the instrument draws the strip into the housing
immediately and starts the measurement irrespective of the strip’s individual
reaction time. Hence, you need to place the strip onto the strip holder as soon
as the reaction time has run out. In such a way, you can potentially generate a
higher strip throughput.
To activate/deactivate the reaction time, press the respective choice button in
the option field and confirm with

15. Quality control
The instrument performs a self-calibration whenever it is turned on. Therefore,
in general, the instrument does not need to be calibrated. To check instrument
performance, we recommend to run multiple standard measurements with
known concentrations within the tests range. If such results are not within the
test’s confidence interval (see 13.1.1 Confidence interval), please contact your
distributor or NOVASSAY directly (see 18.5 Contact).
For additional quality control assessments, you can also use the instrument’s
check mode and special control strips (see 12. Check mode).

16. Cleaning and maintenance
To ensure correct functioning of the instrument for a long time, the instrument
needs to be cleaned and maintained carefully. Generally, the instrument has to
be turned off and disconnected from the power supply, before you start cleaning
it.
16.1 Daily cleaning
The test strip slide has to be cleaned every day as to ensure the correct
functioning of the instrument.
Carefully remove the transport slide. To do so, pull on the upper black plastic
cover. Rinse the slide with clear water, if necessary, you can use some mild
cleaning agent as well. To disinfect the slide, you can use alcohol based
disinfectants (70-85 % ethanol or isopropanol). After disinfection, rinse the slide
with water again. Also clean the metal part of the transport slide. To fit the
plastic cover on the metal part again, simply push the plastic cover onto the
metal part. You can push the entire slide completely into the housing to ensure
a proper fir of metal part and plastic cover.
Note: Do not clean the transport tray in a dish-washer.
16.2 Weekly cleaning
Housing and touch screen should be cleaned at least once a week. Wipe the
housing with a damp cloth. If necessary, you can use a mild cleaning agent.
Then, dry the housing with a soft cloth. Make sure that no water penetrates the
housing or gets into the printer. To clean the touch screen, use a soft, lint-free
cloth. If necessary you can use special LCD cleaning fluid, which is
commercially available.
Note: Never use aggressive, organic solvents such as acetone for cleaning the
instrument. We recommend isopropanol for cleaning and disinfection.
