Many users in the area of sample storage work with the familiar cryotubes in 81 or 100 format. As a rule, the existing volume of the tubes is not used optimally. This circumstance leads to a waste of storage capacity. The SBS sample archiving system from LVL solves this problem and has numerous features that help to ensure not only the integrity of the sample, but also the transfer of information that is essential for the clear assignment between container and sample. We all agree that its time for greenthinking instead of greenwashing and based on that LVLs new 100% recycled rack series will be introduced. In addition to shared experiences and physical background, an innovative laser marking system is being introduced that ensures long-lasting and robust marking of the tubes, while saving working hours of routine work that instead can be invested in productive activities.
