What our customers say

"We chose Micronic because of their strong reputation in Biobank sample storage, the good quality of their automation-compatible products and the assured traceability that their laser etched 2D coded tubes provide."

"We use the Micronic sample storage products because the individual barcoded tubes allows us to easily swap tubes from plate to plate. As we have over 70,000 DNA samples, it is preferable to keep a sample in a single tube then split over several plates."
