The surfaces of the Ultra Low Retention tips are produced through a special, patented physicochemical process. The homogeneous, defect-free surface thus produced has extremely low surface tension – over 50% less than PTFE. This significantly reduces sample loss and provides substantially higher reproducibility when working with critical media.
Ultra-hydrophobic tips are ideal for biological samples that contain detergents such as Triton™ X-100, SDS, Tween etc.
No additives that can be leached out! No siliconization of the surface!
High chemical resistance. Ideal for working with solvents
The tips can be autoclaved at 121°C (2bar) without damaging the material properties
Non-self-sealing filter tips from BRAND have a PE filter that is free from chemical additives. Permeability is controlled by the combination of pore size and filter length, so that no aerosols can reach the pipette shaft. These filters function with consistent reliability. On the other hand, liquids can pass very slowly should they accidentally contact the filter. Since the filter does not swell as in the case of self-sealing filter tips, the sample can be recovered from the filter by simply actuating the pipette's blow-out function, or by centrifugation if necessary. This is clearly an important advantage of non-self-sealing filters, especially when working with valuable samples. As an added advantage, the absence of filter additives protects samples from contamination.
The 50-1000uL Filter Tip is 70mm long. Proven thin-walled tip for routine laboratory and research pipetting. Graduation at 250, 500 and 1000uL for a quick volume check. The racked tips are colorless and placed into a blue-colored tip tray.

Packaging: All tips are available in convenient rack formats. Non-pigmented tips are inserted into color-coded carrier plates for easy identification. Colored tip-racks (tip-trays) are printed on one side with information of the contents.
Bio-Cert Sterile Filter Tip-Box: 96-unit format TipBox has a hinged lid - remove and rotate the lid 180 degrees if you prefer a lift-off design. Opening and closing with one hand. The clamping mechanism holds the tip-tray securely in the box. Transparent window for easy visual inspection. No deflection during tip loading. The tip-tray is fabricated from especially rigid PP. Usable with a partially loaded multichannel pipette. The rimless tip-tray border enables problem-free loading of individual pipette tips with multichannel instruments. Tip boxes are stackable, autoclavable at 121°C, and are reloadable with our TipRefills.
