Sartorius launches Sterisart NF
Sartorius has introduced Sterisart NF, a completely closed
system based on the membrane filtration method for reliable and convenient
sterility testing. Sterisart NF sterility test units eliminate the need for
handling membrane filters, while maintaining a closed system throughout the
entire sterility test. This reliably ensures that major risks for
secondary contamination and false-positive results are excluded. Virtually all pharmaceutical containers and product types can be tested thanks to the use of different adapters. Moreover, Sterisart Gamma units are supplied in a new innovative packaging, which has been validated against all disinfectants commonly used in isolators (e.g. H2O2). This makes handling the units in the isolator much easier and safer.

Eppendorf introduces Dualfilter Tips
Eppendorf has introduced a new product called Dualfilter
Tips. The new Eppendorf ep Dualfilter T.I.P.S. are the first tips with a
two-phase filter for ultimate aerosol 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). ep Dualfilter T.I.P.S.
contains 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. Only ep Dualfilter T.I.P.S. provide reliable protection
against even the finest impurities. 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.
