Testimonials

What our customers say

“We used the 6.00ml externally threaded tubes with 2D Data-Matrix code on the bottom. It was critical for us to have a good sample ID, so the 2D Data-Matrix code on the bottom and the 1D Rack barcode helped us to keep good track of our samples.”

"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."
