Rectangular cells are used for most UV/VIS routine analysis. By far the most common type of cell, they have two windows clear and conform to international standard dimension. The 10mm pathlength size should fit most instruments that use rectangular cells. Available pathlengths are from 1mm to 100mm. Check with your instrument manual to see if you need an adaptor for longer pathlength cells.
Standard Rectangular cells are the most commonly cells used. The have two polished windows and a full interior width used in most instruments.
Flow cells are used for measuring samples with continuous flow as in chromatography or production systems. They are also used in sipper systems where individual samples are aspirated into the cell. Flow cells are made in a wide array of designs because each application has a different compromise of sample volume, flow pattern, pathlength and tubing requirements. We make a wide range of flow cells and have made every effort to simplify the process of selection as much as possible.

The DMV Bio-cell from Starna is the elegant solution to direct, accurate measurement of nucleic acids or proteins in low volume biological samples. The Bio-cell is compatible with any conventional UV spectrophotometer and its magnetic closure design facilitates rapid filling and emptying and easy cleaning, providing cost-effective, easy-to-use low-volume analysis. For those working in the regulated environment, Starna’s expertise in cell technology is combined with Performance Qualification using specially developed Certified Reference Materials to give truly validated measurements and the ultimate confidence in results.
- Direct low volume analysis of nucleic acids and proteins
- Available with 2.5, 1.0 and 0.6 μl volumes
- High accuracy and reproducibility
- Validated measurements
- Certified Reference Materials for OQ/PQ
- Certified path length option
- Compatible with all major UV/Visible spectrophotometers
Precision micro-machining techniques and advanced materials are used to create a patented high energy optical system, so that low volume samples can be measured accurately and reproducibly across a wide absorbance range. The DMV-Bio Cell is available in 0.5, 0.2 and 0.125 mm path lengths for direct measurement of sample volumes of less than 2.5 μl (down to 0.6 μl) for all life science applications. If required, these path lengths can be certified. Cells are available with Z heights of 8.5 mm or 15 mm to suit a wide range of instrument designs
Certified Reference Material
Assuring analytical quality – Starna Reference Materials for Spectroscopy
Starna Scientific, pioneers in the development of Certified Reference Materials (CRMs) for spectroscopy, offer the world’s most comprehensive range of materials for Instrument Qualification and performance evaluation. Manufactured and calibrated under strictly controlled conditions, these materials conform to all the relevant international standards and quality protocols. As a world leader in this technology, Starna has played a pivotal role in the development of CRMs for spectroscopy over many years, in close collaboration with international regulatory bodies and instrument manufacturers.
The range of Starna reference materials is continually expanding and includes references for ultraviolet and visible spectrophotometry, for fluorescence, NIR and Raman spectroscopy, references for use in plate readers and HPLC instrumentation, and a range of specialised materials for use in bioscience. References are also available in convenient sets for instrument qualification to the requirements of Pharmacopoeias and other regulatory bodies.
The calibration of Starna Certified Reference Materials is traceable to international primary standards, allowing laboratories to demonstrate evidence of quality control according to ISO/IEC 17025, the universally recognised standard for laboratory accreditation. The Starna calibration laboratory was one of the first to be accredited to this standard, in 2001, and in 2006 Starna was further accredited as a reference material producer, to ISO Guide 34.
Other unique benefits of choosing Starna reference materials:
Liquid references, including volatile and flammable materials, are permanently sealed by heat fusion into their cells. This process, developed by Starna, eliminates evaporation, improves stability and makes handling safer.
Starna CRMs are covered by a lifetime guarantee.
References can be re-certified and dispatched within five working days of receipt at the Starna calibration laboratory.
Reference material sets can be customised to user requirements.
