Your pipette and sample are safe with ep Dualfilter T.I.P.S.® and ep Dualfilter T.I.P.S.® SealMax
Eppendorf ep Dualfilter T.I.P.S. were the first tips with a two-phase filter for ultimate protection against aerosols and biomolecules. Building on the technology present in the first Dualfilter, Eppendorf expands its current ep Dualfilter T.I.P.S. portfolio with a self sealing tip, the new ep Dualfilter T.I.P.S. SealMax with liquid blocking technology is recommended for when you need additional protection against over pipetting. ep
Dualfilter T.I.P.S. and ep Dualfilter T.I.P.S. SealMax are manufactured to the highest quality standards from pure, non-recycled materials under cleanroom conditions without the use of interfering slip agents, biocides or plasticizers.
Ideally suited for methods where high sensitivity and reproducibility are essential, ep Dualfilter T.I.P.S. and ep Dualfilter T.I.P.S. SealMax are especially recommended for applications such as PCR and microbiology where preserving sample integrity and preventing cross contamination are critical.
Aerosols Don’t Stand a Chance
Eppendorf ep Dualfilter T.I.P.S. were the first tips with a two-phase filter for aerosol contamination protection. The unmistakable blue and white filter layers are made of flexible, hydrophobic material designed to fit perfectly in the tip cone and retain nearly 100 % of all aerosols* and biomolecules. The unique filtering effect is achieved using various, well defined pore sizes in the two filter layers. The hydrophobic white layer additionally protects against splashes and droplets. Both filters, ep Dualfilter T.I.P.S. and ep Dualfilter T.I.P.S. SealMax, are made of Polyethylene (PE) and have comparable pore size structure. In a filter efficiency test, based on the standard EN 1822 and completed by a certified institute showed a minimum particle collection efficiency of 99.5% with NaCI aerosol particles sizes of 0.05–0.5 μm.
* Aerosol: Aerosol particle and the air or dispersion of solid or liquid particles surrounding it in a gas, usually air.
Free of PCR Inhibiting Additives
No PCR inhibition even if sample make contact with Dualfilters
The polymerase chain reaction is a common application in molecular biology research. However, it can not be excluded that the filter material may come into contact with the PCR sample, which can negatively affect the efficiency of classic PCR and quantitative real-time PCR. Eppendorf Dualfilters of ep Dualfilter T.I.P.S. and ep Dualfilter T.I.P.S. SealMax practically have no effect on PCR reactions and therefore are particularly well suited for preparing PCR experiments — both classic PCR and real-time PCR.Filter tips are well suited for the preparation of these types of experiments.
Safety Sealed With ep Dualfilter T.I.P.S. SealMax
Eppendorf‘s new ep Dualfi lter T.I.P.S. SealMax fi lter tips provide comprehensive protection against contamination of your pipette and sample. They combine the same high level of aerosol and biomolecule protection as ep Dualfilter T.I.P.S. with the reliable capability of sealing against liquid penetration upon contact.
When it comes to an accidental over-pipetting situation, the new violet layer of ep Dualfi lter T.I.P.S. SealMax becomes a reliable barrier against sample liquid — no liquid will pass through the filter! Your pipette is safe at all times! Additionally nearly 100 % of aerosols and biomolecules are retained while the hydrophobic white layer protects against splashes and droplets.
