BRAND Ultra-Low Retention pipette tips are produced through a patented physicochemical prodess that provides a homogeneous defect-free surface. This results in an extremely low surface tesnion, over 50% less than PTFE. This significantly reuces sample loss and improves reproducibility. BRAND Ultra Low Retention tips have no additives than can leach out, or coatings to wash off. Fully autoclavable at 121 C without damage to surface properties.
BRAND filtered nano-cap pipette tips are a shorter style (37mm) ultra-micro/crystal tip that removes contaminating aerosols when pipetting volumes 1 microliter or smaller. A unique capillary rise gives a visual check. Non-self-sealing filters allow easy recovery of sample if filter is wetted. PE filters are free from additives. Required for use with BRAND sub-micro (0.1-1 microliter) Transferpette and Transferpette S models.
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 be a lift-off design. Ordering Information: All rack-packed tips are DNA-, RNase-, ATP-, and endotoxin-free.
