Safe-Lock micro test tubes, 1.5 ml, assortment, 1000 pcs.

Manufactured by Eppendorf, these 1.5 ml Safe-Lock micro test tubes are made from virgin polypropylene and produced without the use of slip agents, plasticizers, or biocides, substances known to leach from plastic consumables and negatively affect bio-assay results [S1][S3].

The hinged Safe-Lock lid is engineered to prevent unintentional opening during incubation and storage, while a precise sealing design supports minimal evaporation rates during long-term storage. A large frosted lid and side surface provide ample space for labelling. The tubes are rated for use from -86 °C to 100 °C and are autoclavable when open at 121 °C for 20 min [S1].

Supplied in the Eppendorf Quality purity grade, the 1.5 ml Safe-Lock variant delivers exceptional centrifugation stability of up to 30,000 × g, helping prevent sample loss due to tube breakage and providing extra safety when working with hazardous samples. Eppendorf introduced the first microtube to laboratories in 1963, and the Safe-Lock range reflects 50 years of continuous improvement and development [S1][S3].
