Eppendorf Pipette Tips 20 ul Dualfilter 10 Racks with 96 Tips Each

Description

Eppendorf 0030078535 ep Dualfilter T.I.P.S. – 20 uL, PCR Clean & Sterile

The Eppendorf 0030078535 is a high-precision 20 uL filtered pipette tip engineered to provide the highest level of sample protection available in modern liquid handling. Utilizing the proprietary Dualfilter technology, these tips feature two layers of flexible, hydrophobic polyolefin material with different pore sizes. This unique design ensures that both aerosols and liquid droplets are effectively trapped before they can reach the pipette shaft. Certified as PCR Clean and Sterile, these tips are manufactured under stringent cleanroom conditions to be completely free of human DNA, DNase, RNase, and PCR inhibitors, making them an essential consumable for genomics, forensic analysis, and diagnostic testing.

Technical Performance and Design

• Dualfilter Aerosol Barrier: The two-phase filter system provides double the protection of standard filters. The top layer (facing the pipette) blocks droplets and large aerosols, while the bottom layer (facing the sample) traps fine particles, ensuring 100% barrier efficiency against radioactive or infectious amplicons.

• PCR Clean & Sterile Certification: Every batch is independently tested and certified to meet the highest purity standards. This ensures that no exogenous DNA or degradative enzymes are introduced into your master mixes, safeguarding the sensitivity of qPCR and NGS library preparations.

• Optimized Tip Geometry: The “T.I.P.S.” (Totally Integrated Pipetting System) design ensures a perfect, leak-proof seal and low attachment/ejection forces. This precision molding guarantees exceptional volumetric accuracy and reproducibility, even at the low 2 uL to 20 uL range.

• Hydrophobic Surface: The high-quality virgin polypropylene construction is naturally hydrophobic, promoting low liquid retention and ensuring that the full 20 uL volume is dispensed without leaving residual film behind.

Key Benefits & Applications

• High-Sensitivity PCR/qPCR: Prevents aerosol-based carryover contamination between samples, which is critical for maintaining the accuracy of low-copy-number DNA detection.

• RNA Research: The RNase-free certification ensures that delicate RNA samples remain intact and protected from degradation during the pipetting process.

• Handling Pathogens or Radioisotopes: The dual-layer filter acts as an absolute fail-safe, shielding the internal piston of the pipette from hazardous or corrosive vapors.
