BRAND® Ultra-Low Retention pipette tips are produced through a patented physicochemical process that provides a homogeneous defect-free surface. This results in an extremely low surface tension, over 50% less than PTFE. This significantly reduces sample loss and improves reproducibility. BRAND® Ultra Low Retention tips have no additives that can leach out, or coatings to wash off. Fully autoclavable at 121°C without damage to surface properties.
BRAND® filtered ultramicro pipette tips are an excellent choice to reduce contaminating aerosols when using pipettes with ultramicro/crystal tips. Two different designs are available: a 0.5-10 microliter size, which is 46mm long and has graduations at 2 and 10 microliters; and one that is suitable for volumes from 1–20 microliters, is 50mm long, and has graduations at 2.5 and 10 microliters. Non-self-sealing filters allow easy recovery of sample if filter is wetted. PE filters are free from additives.
All tips are produced under cleanroom conditions. New environmentally friendly refillable TipBox design is rigid and allows partial loading of multichannels. Hinged lid can be rotated 180 degrees to create a lift-off design. Ordering Information: All rack-packed tips are DNA-, RNase-, ATP-, and endotoxin-free.
