The Laboratory Photometers category includes the instruments, accessories and consumables needed to collect, prepare and test real-world samples for chemical, physical and biological indicators linked to quality, compliance and process control. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately.
Field variability and complex sample matrices make representative sampling, correct preservation and method-appropriate equipment especially important. A well-matched setup balances sample matrix, target parameter, method range, and field or laboratory use, helping the laboratory avoid unnecessary rework, difficult cleaning or premature replacement.
Reliable work links sampling and preservation with digestion, incubation or extraction, followed by calibrated measurement and clear documentation. When each stage is matched correctly, laboratories in water authorities, agriculture, food production, environmental consulting, mining, education and contract laboratories can work more consistently and manage changeovers, replenishment and maintenance with fewer interruptions. As part of the Environmental, Soil & Water Analysis for Labs range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Photometers range
Our collection covers the xylem wtw photoflex in the field, a photometer and a spectrophotometer, cuvette size, and photometers accessories and workflow integration, giving laboratories practical choices for routine work and more specialised applications.
The Xylem WTW PhotoFlex in the field
The PhotoFlex series is specifically designed for portable use, featuring a robust housing and intuitive interface for high-precision water testing outside of the traditional lab environment. The most suitable format depends on sample matrix, target parameter, and method range. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. Within the wider method, these products help laboratories maintain continuity from field collection through preparation, measurement and reporting. They should be reviewed together with associated consumables, accessories and cleaning requirements.
A photometer and a spectrophotometer
A photometer generally measures light at specific fixed wavelengths, while a spectrophotometer like the Tintometer XD 7500 can scan across a wide range of wavelengths (UV and Visible) for more complex analysis. When comparing options, consider target parameter, method range, and field or laboratory use. The correct choice should fit the sample, expected workload and any equipment already used in the method. Used correctly, this part of the range helps laboratories maintain continuity from field collection through preparation, measurement and reporting. The result is a setup that is easier to train, document and maintain.
Cuvette size
The diameter of the cuvette, such as the Tintometer 24 mm round vials, determines the light path length; consistent sizing is vital for calculating concentrations accurately based on Beer-Lambert's Law. For routine and specialised work, assess method range, field or laboratory use, and sample preparation needs. Matching these points early helps avoid adapters, consumables or operating limitations being discovered after purchase. Used correctly, this part of the range helps laboratories maintain continuity from field collection through preparation, measurement and reporting. The result is a setup that is easier to train, document and maintain.
Laboratory Photometers accessories and workflow integration
DPD No. 1 tablets are standardized reagents used to develop a colour reaction in the presence of chlorine, which the photometer then measures to determine concentration. Selection should take account of field or laboratory use, sample preparation needs, and calibration and reporting. It is also worth checking cleaning, replacement and storage requirements before the item becomes part of a routine procedure. Within the wider method, these products help laboratories maintain continuity from field collection through preparation, measurement and reporting. They should be reviewed together with associated consumables, accessories and cleaning requirements.

Frequently Asked Questions
Can the Xylem WTW PhotoFlex be used in the field?
The PhotoFlex series is specifically designed for portable use, featuring a robust housing and intuitive interface for high-precision water testing outside of the traditional lab environment. Laboratories should compare target parameter, method range, and field or laboratory use and document the selected setup for consistent use.
What is the difference between a photometer and a spectrophotometer?
A photometer generally measures light at specific fixed wavelengths, while a spectrophotometer like the Tintometer XD 7500 can scan across a wide range of wavelengths (UV and Visible) for more complex analysis. For photometers, also check target parameter, method range, and field or laboratory use so the product fits the complete procedure.
Why is cuvette size important?
The diameter of the cuvette, such as the Tintometer 24 mm round vials, determines the light path length; consistent sizing is vital for calculating concentrations accurately based on Beer-Lambert's Law. Before ordering, confirm target parameter, method range, and field or laboratory use and any accessories or consumables needed for routine use.
What are DPD tablets used for in photometry?
DPD No. 1 tablets are standardized reagents used to develop a colour reaction in the presence of chlorine, which the photometer then measures to determine concentration. Laboratories should compare target parameter, method range, and field or laboratory use and document the selected setup for consistent use.
What should I check before ordering photometers?
Start with the application and sample, then compare target parameter, method range, field or laboratory use, and sample preparation needs. Check compatibility with existing equipment and confirm any accessories, consumables, calibration items or replacement parts required for routine use. Laboratories should compare target parameter, method range, and field or laboratory use and document the selected setup for consistent use.
