Testimonials (partial) Technospex offers a low cost and most importantly high quality Raman micro-spectrometer, the uraman, that easily competes with (and outperforms, in some cases) industry-standard systems. Our lab is very happy with the performance and flexibility of the system. An added benefit is the field-upgradability of the hardware and software a critical feature as we can quickly customize and add features for specific experiments with essentially zero downtime. Finally, the exceptional technical support from Technospex has made our experience with the uraman very productive. Dr. Sapun Parekh, Group Leader Max Planck Institute for Polymer Research Germany TechnoSpex s uraman small footprint was ideal for our undergraduate teaching lab, and the fully integrated yet simple design also allows our students to execute measurement easily. What really caught our initial interest was its ease in obtaining beautiful spectrum even from samples with monolayer thicknesses such as 2D materials, which our research labs are doing with systems costing much more. Thus far, the system has been performing very well and beyond our expectations. We are also very happy and impress by their attention to customer needs and the level of technical support provided in meeting our teaching lab demands.
