Eppendorf Safe-Lock Tubes 1.5mL Colorless PCR Clean pack of 1,000

Eppendorf Safe-Lock Tubes 1.5mL Colorless PCR Clean grade

About the range:

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:

• Colorless tubes
• PCR Clean grade

  

• Supplied in packs of 1,000 tubes
• Hinged Eppendorf Safe-Lock lid prevents unintentional lid opening during incubation and storage
• Polypropylene 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^®: 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
• 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)

PCR Clean

The arrival of PCR (polymerase chain reaction) and many additional molecular biological methods in clinical and research laboratories required new purity criteria, also for consumables. The analysis of the individual criteria by Eppendorf was used for defining the requirements for PCR consumables.

Which requirements does "PCR clean" fulfill?

• All Eppendorf consumables with the purity grade PCR clean are DNase and RNase free. The miniscule amounts of genetic substance used for experiments are therefore protected from DNases and RNases.
  • Testing the absence of DNase and RNase: Reaction buffers with a DNA or RNA ladder are incubated at 37°C in the consumables for several hours. There must be no trace of DNA or RNA digestion.
• It is also guaranteed that the consumables are free of contaminating nucleic acids. This is normally human DNA, which could infiltrate the plastic goods during the production process (e.g. via skin particles).
  
  • The absence of human DNA is verified by PCR analysis. The detection limit is ≤2 pg DNA. This quantity is smaller than a single human cell.
• Absence of PCR inhibitors: Consumables certified by Eppendorf as PCR clean are free of any PCR inhibitors and will not interfere with the PCR reaction.
  
  • The consumables are tested in a separate PCR experiment against a standard reaction.
• Furthermore, all Eppendorf PCR clean products fulfill the quality standards defined for our standard consumables. The requirements regarding wetting behavior, liquid tightness, accuracy, chemical resistance, etc. are met in full.
