Thermo Fisher, 2149P-HR, ART™ Barrier Pipette Tips in Hinged Racks

ART™ Barrier Pipette Tips in Hinged Racks is designed for small-volume reagent transfer, assay setup and PCR master-mix dispensing where a 20 µL filtered tip is appropriate. This 20 µL configuration is a sterile, filtered, universal-fit tip supplied in hinged racks; the model is ART 20P. Each case contains 4,800 tips. ART barrier technology incorporates a filter that seals when exposed to potential contaminants, helping prevent sample material from reaching the pipette shaft during aspiration or dispensing. This physical barrier helps reduce the possibility of carryover during sensitive liquid-handling operations. The supplied tips are designated DNase-free, RNase-free, DNA-free, ATP-free, PCR-inhibitor-free and endotoxin-free, making the format suitable for nucleic-acid analysis and other contamination-sensitive work. The hinged rack is stackable to conserve bench and storage space. Its cover can be used in a hinged or lift-off orientation, and the locking clasp keeps unused tips protected during routine access. The rack format allows one-handed opening and is compatible with the corresponding refill inserts. This version uses the standard universal-fit tip style rather than the separately available low-retention or ultra-micro variants. The specific 20 µL volume and case quantity distinguish this configuration from the other ART hinged-rack options.
