“I chose Micronic because of the space saving 96-well rack format; more sample material could fit in the freezer compared to products from other companies. The screw cap also stays securely in place during long-term storage in -80°C."

Using a unique tube coding system from Micronic, the Animal Sciences Group has been able to significantly improve the absolute traceability, throughput and long term storage integrity of labelled samples going through their laboratory.

"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."
