The devices from the P9000 series are digital polarimeters that were designed to measure the optical rotation, specific rotation or concentrations of liquid, optically active samples. The measurement is based on the ability of optically active substances to rotate the polarization direction of light. By determining the rotation, the substance and its concentration is determined. With an optical sensor, temperature control, measuring electronics, evaluation electronics and a touch display, the devices contain all the components needed to carry out measurements reliably.
The devices and their firmware meet all requirements for FDA-regulated areas, as well as for the European (EP / Ph. Eur.), American (USP), British (BP) and Japanese (JP) pharmacopoeia.

POLARIMETER CUVETTES
Transparent. Simplified. Unique.
Take advantage of our modern cuvette design: the new, rectangular shape offers numerous functional advantages over classic, round polarimeter tubes – and in particular facilitates handling, temperature control and bubble detection
MINIMUM SAMPLE VOLUME
A volume of just 1.3 ml is sufficient for precise measurement with our 100 mm long cuvette. Filling is done conveniently with a syringe – either directly in the temperature-controlled polarimeter or outside on the laboratory bench. The user-friendly design with a flat base enables safe, easy handling.
AUTOMATIC CUVETTE RECOGNITION
For an intuitive measurement and calibration process, the polarimeter automatically recognizes the cuvette equipped with an RFID tag and records all relevant cuvette data such as:
- Length
- Material
- Temperature control parameters
For maximum process reliability, error-free documentation and automated measurement and calibration processes.
INSIGHTS INTO YOUR SAMPLES DURING FILLING
The rectangular shape of our glass cuvettes allows visual control of the sample filling over the entire length of the cuvette. As with an aquarium, the sample can be inspected from all sides – air bubbles, particles or streaks are immediately visible. This makes it very easy to detect and reliably avoid measurement errors with the naked eye.
AUTOMATIC DOCUMENTATION OF SAMPLE FILLING
With the Sample Cell Check, the filling process itself becomes part of quality assurance. The cuvette can remain in the polarimeter during filling. An integrated camera transmits the filling process directly to the display – conveniently, precisely and without interrupting temperature control. The automatic sample cell check function reliably checks and documents the entire filling process. Especially with automated sample supply (e.g. with autosamplers), the recorded and stored images can be used for documentation or error analysis. This allows you to rule out potential sources of error in advance – for reproducible and reliable measurement results.
Homogeneous sample temperature control
Thanks to its well thought-out rectangular shape, the cuvette is actively tempered across all side surfaces. The result is a homogeneous temperature distribution in the sample over the entire length of the cuvette – without any disturbing gradients. This ensures that your sample is consistently maintained at the optimal temperature – providing stable conditions and highly accurate measurement results.
- Fast temperature stabilization for short measurement preparation times
- Homogeneous temperature curve – no measurement deviations due to temperature gradients
- Maximum measurement accuracy due to constant sample conditions
EASY TO CLEAN DOWN TO THE LAST DETAIL
Quick to clean – in record time
Our cuvettes are fully dismountable – in just 8 seconds, as demonstrated by our current record.
In doing so, we deliberately rely on a design without active electronic components:
Waterproof, robust and durable.
THE OPTIMAL CUVETTE FOR EVERY APPLICATION
We offer a large selection of different polarimeter cuvettes:
Materials: glass, stainless steel or Hastelloy
Lengths: 50 mm, 100 mm or 200 mm
Do you need a cuvette with special properties or dimensions? No problem – we also offer customized solutions specifically for your measuring task.
Our cuvettes combine ease of cleaning, optimum temperature control and maximum flexibility – so that you can concentrate fully on your measurements.
CALIBRATE AND ADJUST
Automatic. Precise. Certified.
Intuitive calibration with wireless RFID recognition. Each of our quartz control plates is equipped with an RFID tag. When the quartz is inserted into the polarimeter, detection is automatic and wireless – without any manual input. Fast, secure and standardized. Calibration then starts in a menu-guided and user-friendly manner directly via the display of your device.
TEMPERED QUARTZ CONTROL PLATES
Precision starts with the temperature
Quartz control plates are characterized by extremely stable optical properties – ideal for the calibration and adjustment of polarimeters. But even with solids such as quartz, temperature changes have a direct effect on the angle of rotation.
Example: For a quartz control plate with a defined angle of rotation of +34°, a temperature deviation of just 1°C leads to a measured value shift of 0.005°.
The optical rotation of quartz increases with temperature – exact temperature control is therefore crucial for reliable measurement results. Our intelligent TempGate® system automatically achieves the required accuracy of temperature control and keeps it constant.
PTB-CERTIFIED QUALITY
We only use quartz control plates certified by the Physikalisch-Technische Bundesanstalt (PTB) – both for the manufacturer’s calibration of our polarimeters and for later use in your laboratory.
- Traceability to national standards
- Highest precision and long-term stability
- Reliable reference values over many years

CUSTOMER CARE
Transparent. Efficient. Plannable.
When buying a measurement device, it is not just the purchase price that counts, but the total cost of use over its lifetime.
Hidden service or maintenance costs can quickly add up to several thousand euros.
We offer full cost transparency right from the start so that you can plan for the long term, avoid surprises and make efficient use of your investment.
TOTAL COST OF OWNERSHIP (TCO)
The real cost of a measurement device only becomes apparent during operation. That’s why it’s not just the purchase price that counts when buying – the total cost of ownership over the lifetime of the device is decisive. A cost comparison pays off in several ways; in addition to knowing the usage costs, different measurement devices can also be compared with each other very well.
We consistently focus on complete cost transparency and thus create the basis for long-term, reliable planning. Hidden service and operating costs are unfortunately no exception in the procurement process. Many supposed additional services initially seem attractive, but over time they become fixed cost factors.
Example:
Extended warranty promises are often linked to regular, verifiable maintenance. These require trained personnel as well as special measuring and calibration equipment – and cause additional organizational and financial expenditure. It is not uncommon for such services to be purchased later from the manufacturer for a fee. Over a useful life of ten years, this can result in cost differences of several thousand euros.
We offer full cost transparency right from the start – so that you can plan your investment for the long term, avoid surprises and use it with maximum efficiency. Holistic assessment, honest solutions, complete security: this is how TCO makes the difference.
