All BRAND pipette tips are produced using the most advanced cleanroom techniques to ensure consistently high quality. The tips are manufactured in an environmentally friendly manner using only high-purity polypropylene, free from oleamide and diHEMDA - additives which can interfere with biological tests. The surface of the Ultra-Low Retention tips are treated with a special patented physicochemical process producing a surface tension over 50% less than PTFE! There are no additives to leach out, or coatings to contaminate the sample. These tips greatly reduce sample loss, and provide higher reproducibility. ULR tips are available non-sterile, BIO-CERT® sterile, or filtered BIO-CERT® sterile in volume sizes ranging from 0.1-1µL to 50-1000µL.
