A high-precision quartz glass flow-through cuvette with a superfine channel is at the heart of every cytometer. This channel lends stability to the fluidic system, enabling the accurate optical analysis of individual cells or particles. At Hellma Analytics, the production of cytometer cuvettes draws on more than 95 years of experience in producing glass and quartz components. Thanks to our use of advanced glass processing we are able to manufacture microchannel, cytometer cuvettes featuring polished channel surfaces and made from fluorescence-free materials in custom sizes as small as 50 μm x 50 μm. The consistently high production quality guarantees maximum reproducibility with minimum tolerances. Our exceptional production expertise combined with our state-of-the-art production machinery enable us to manufacture cuvettes with various cone shapes as well as solutions tailored to our clients’ requirements.
