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 pipette tips for pipettes using 200uL tips are an excellent choice to reduced contaminating aerosols when using pipettes with a yellow color code. Three different designs are available: a 2-20 microliter size; a 5-100 microliter size, and a 5-200 microliter size. Non-self-sealing filters allow easy recovery of sample if filter is wetted. PE filters are free from additives. While the collar of the tips will fit most pipettes, filter location may affect tip fit.
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.
