Eppendorf Safe-Lock Tubes, 2.0 mL, Eppendorf Quality™, yellow, 1,000 tubes

Eppendorf Safe-Lock Tubes are the result of 50 years of continuous improvement and development. The original Safe-Lock tubes protect your sample with excellent centrifugation stability, feature optimized sealing properties, and reliably prevent sample evaporation. Trust in the original Eppendorf Safe-Lock Tubes, because your samples deserve nothing but the best.

Features

• Hinged Eppendorf Safe-Lock lid prevents unintentional lid opening during incubation and storage
• g-Safe®: Depending on Safe-Lock Tube variant (see manual) exceptional centrifugation stability up to 30,000 × g prevents sample loss due to tube breakage and provides extra safety when working with hazardous samples
• 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
• Polypropylene provides high resistance to chemicals, mechanical stress and temperature extremes
• Precise lid sealing for minimal evaporation rates during long-term storage
• Large frosted lid and surface on the side for easy labeling
• Ensured functionality from -86 °C to 100 °C
• Autoclavable when open (121 °C, 20 min)
• Available in lot-certified PCR clean, Eppendorf Forensic DNA Grade, and Biopur® quality for tested purity
• Available in Eppendorf Protein and DNA LoBind material for maximum recovery of valuable samples and in Amber for light-sensitive samples

Performance

• Seal safety: Original Eppendorf Safe-Lock lid: Always recognize the original Eppendorf Safe-Lock Tubes by the "ep" in the lid. The hinged lid on Eppendorf Safe-Lock Tubes provides outstanding protection against accidental opening of tube lids ensuring highest sample protection. This feature is especially important when working with precious samples, or buffers containing detergents such as SDS.
  During incubation in a boiling water bath, only the Eppendorf Safe-Lock Tubes remained safely closed. 10 % to 20 % opened lids were found for the tubes of manufacturers S and A, while T and G exhibited more than one–third and V nearly 80 % opened lids.
• Highest sample integrity: 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 or measurements, e.g. nucleic acid quantification by photometric measurements at 260 nm.
