These safe-lock tubes protect the sample with excellent centrifugation stability, feature optimized sealing properties, and reliably prevent sample evaporation.

• Hinged lid prevents unintentional lid opening during incubation and storage
• Precise lid sealing for minimal evaporation rates during long-term storage
• Large frosted lid and surface on the side for easy labeling
• Guaranteed functionality from ‒86 to 100 °C
• Autoclavable when open (121 °C, 20 min)

Provides high resistance to chemicals, mechanical stress and temperature extremes. Manufactured without the use of slip agents, plasticizers, and biocides – substances that have been shown to leach from plastic consumables into the sample and negatively affect bio-assay results. g-Safe® with exceptional centrifugation stability up to 30000×g and prevents sample loss due to tube breakage and provides extra safety when working with hazardous samples.
