Medical grade PP, sterile or non sterile, autoclavable
These tips are made of high quality 100% pure virgin medical grade PP. Made in the highest quality moulds, these tips can be used whenever the work demands a higher standard. Sterile products are tested for endotoxin (pyrogen) contamination and are certified to USP standards. Resins are pre-tested for metal contamination. Certificates are on file by lot number for all test results.
- A wider seal ensures that tips will seal easily and consistently without leaking
- Guaranteed free of detectable DNA, DNase/RNase, endotoxins and heavy metals
- Graduated tips only: Graduations allow a visual check of pipetting accuracy
UltraFine™: Pipette tips with Ultrafine™ point feature a thin flexible section at the end that is non beveled and very flexible. This helps you dispense the last tiny amount of sample from the tip.
FlexTop™: These ultimate tips feature a uniquely thin and flexible top that conforms to the pipette barrel unlike any other tips. This design allows them to mount and eject from most pipettors with forces that help eliminate the potential for repetitive strain injuries.
Wide orifice: Extra wide opening allows you to pipette macrophages or sticky DNA materials. Beveled end helps eliminate carry over from viscous solutions.
Low binding: The low retention tips are made with a special resin that reduces the potential for sample retention inside the tip. They will help you reduce sample loss when performing protein research. We lot certify them to be free of protease as well as nuclease.
Bulk: Tips are either supplied in resealable PE bags (1000 tips) or in one large bag inside a corrugated container (10000 tips). These packaging options are not recommended if you plan to store the tips for long periods if warping is a concern.
Racks (96 + 192 tips per rack): These racks with smooth rounded edges have heavy hook hinges that are extremely durable and an ergonomic snap latch that won’t catch gloves. Strong enough to be autoclaved many times. The separate rack insert includes a beveled top and extra sturdy surface for multi-channel pipetting.
Stack racks: These high quality racks need to be assembled by the user. You simply have to insert the fully racked refills into the rack. Since the tips are never touched, you do not have to you be concerned about contamination from your hands or latex gloves. These stacks are very stable so you can pipette with a multichannel pipette right from the stack.
Stack Rack refills: These refills are a slimmed down version of the Stack racks. Neatly packed, ready for you to refill the racks you already have.
Individually wrapped: Tips are individually packaged in thermal sealed PE bags. The tips have been radiation sterilised.
