The Lohand Total Iron Test Tube provides a rapid colorimetric method for determining total iron concentrations in water samples. This single-use test tube contains pre-measured reagents that react with iron species to produce a measurable color change within 3-5 minutes of sample addition.
Constructed from PE plastic with aluminum foil sealing, the test tube maintains reagent stability for 18 months under normal temperature storage conditions. The self-contained format eliminates the need for additional laboratory equipment or specialized technical expertise, making it suitable for field testing and routine monitoring applications where traditional wet chemistry methods may be impractical.
How It Works
The test tube utilizes colorimetric analysis based on the formation of colored iron complexes when sample water is added to the pre-loaded reagent system. Iron species in the sample react with the reagent to produce a color change proportional to the total iron concentration present.
The reaction occurs rapidly at ambient temperature, with color development complete within 3-5 minutes. Visual comparison to a color chart or spectrophotometric measurement at the appropriate wavelength provides quantitative determination of iron levels. The sealed reagent system ensures consistent stoichiometry and eliminates potential contamination from external sources.

This test tube system provides a streamlined approach to iron determination through pre-measured reagents and simplified procedure. The combination of rapid results, extended shelf life, and minimal equipment requirements makes it particularly suitable for field testing and routine monitoring applications.
Practical Tips
Store test tubes at consistent normal temperature and protect from extreme temperature variations.
Why: Temperature fluctuations can affect reagent stability and analytical performance.
Remove aluminum foil seal immediately before sample addition to minimize reagent exposure to ambient conditions.
Why: Extended exposure may lead to reagent degradation or moisture absorption.
Use representative water samples and avoid sampling from areas with obvious contamination or stagnant conditions.
Why: Sample quality directly affects the accuracy and relevance of iron measurements.
Handle test tubes carefully to avoid puncturing PE plastic construction or damaging seals.
Why: Container integrity is essential for proper reagent function and operator safety.
Inspect aluminum foil seals before use and discard any tubes showing signs of damage or compromise.
Why: Damaged seals may indicate reagent contamination or degradation.
If color development appears inconsistent, verify sample was adequately mixed with reagents.
Why: Incomplete mixing can result in non-uniform color development and inaccurate readings.
Record ambient temperature during testing for documentation and quality control purposes.
Why: Temperature variations may affect reaction kinetics and color development timing.

Compliance
What is the shelf life and storage requirements for the test tubes?
Test tubes maintain stability for 18 months when stored at normal temperature conditions. The aluminum foil sealing prevents moisture absorption during storage.
How long does the color development reaction take?
Color development is complete within 3-5 minutes of sample addition at ambient temperature, allowing for rapid testing cycles.
What additional equipment is needed to perform the test?
No additional laboratory equipment is required for the basic test. Results can be read visually against a color chart or measured spectrophotometrically for quantitative analysis.
What is the test tube construction material?
The test tube is constructed from PE plastic to provide chemical resistance and prevent container interference with the iron determination.
Can the test tubes be used for field testing applications?
Yes, the lightweight design and self-contained format make them suitable for field testing where traditional laboratory infrastructure is not available.
What happens if the aluminum foil seal is damaged?
Damaged seals may compromise reagent stability and should not be used. Inspect seals before use and discard any tubes with compromised packaging.
What detection range and precision can be expected?
Specific detection range and precision specifications are not provided in the available product information. Consult the product datasheet for analytical performance parameters.
