Unique two-phase filter protection with ep Dualfilter T.I.P.S.^®.
The Eppendorf ep Dualfilter T.I.P.S.^® are the first filtertips with a two phase filter for contamination protection. The tips are manufactured to the highest possible quality from pure, non recycled materials under cleanroom conditions. They are characterized by defined flow dynamics, low wettability and high thermal stability. They are certified pyrogen free and PCR clean (free from human DNA, DNase, RNase and PCR-inhibiting substances).
These ep Dualfilter T.I.P.S.^® contain well-defined different pore sizes within the two filter layers. The white layer which faces the sample retains drops, splashes and aerosols. The blue layer above it forms a highly-effective double barrier, that reliably binds even biomolecules.
Without any kind of filter the pipette is exposed to contamination by sample and aerosols. Conventional single layer filters do not fully block particles and molecules. Only ep Dualfilter T.I.P.S.^® provide reliable protection against even the finest impurities.

Crucial for a wide range of sensitive laboratory applications, including molecular biology techniques like PCR, RNA/DNA work, cell culture, and clinical diagnostics.

• PCR and DNA/RNA Work: These tips prevent contamination that could inhibit PCR amplification or degrade DNA/RNA samples, ensuring accurate and reliable results in genetic analysis and research. Cell Culture: Essential for maintaining aseptic conditions and preventing microbial contamination of cell lines, which is critical for experiments involving cell viability, growth, and differentiation.
• Clinical Diagnostics: Used in applications where sample integrity and accurate detection of analytes are paramount, such as in diagnostic assays where even trace contaminants could lead to false positives or negatives.
• Sensitive Sample Handling: Any application involving precious or low-volume samples that are susceptible to contamination from external sources or from the pipette itself.
• Protection of Pipettes: Dual filter tips act as a barrier, preventing aerosols and liquids from entering the pipette barrel, which helps protect the pipette′s internal components from corrosive reagents or viscous samples, extending its lifespan.
• Pyrogen-free: Ensures that the results are not influenced by endotoxins or other fever-inducing substances, particularly important in cell culture and clinical applications.
• Human DNA-free: Prevents the introduction of exogenous human DNA into samples, which is critical for studies focused on non-human DNA or for forensic applications.
• DNase/RNase-free: Protects nucleic acids from degradation by nucleases, vital for experiments involving DNA and RNA manipulation and analysis.
• PCR-inhibiting substances-free: Guarantees that no chemicals or additives that could interfere with PCR amplification are present, ensuring the efficiency and accuracy of the reaction.
