Discontinued Products
With over 30 years experience in process photometry optek has continually strived to develop the best UV/VIS/NIR and scattered light analyzers. Many of our original systems are still monitoring and controlling processes in plants across the globe! Driven by the continuous improvement of our product lines, we will also occasionally phase out older products. We aim to ensure the spare parts availability of discontinued products for 10 years. For products older than 10 years, the availability of spare parts must be checked on a case-by-case basis. Below you will find information on discontinued products along with a contact form if you need replacements.
