Rainin universal-fit tips provide outstanding performance for non-LTS Rainin pipettes and most other pipette brands, including Gilson, Eppendorf, Sartorious (BioHit), Thermo (Finn) and VWR. Like all Rainin tips, our universal-fit tips are precision engineered and manufactured to ISO 9001 standards in Class 100,000 clean room conditions.

BioClean tips are manufactured under tightly-controlled cleanroom conditions for absolute cleanliness and purity. Each tip lot is rigorously tested, certified and guaranteed to be free of these biological contaminants:

• DNA
• DNase
• RNase
• Pyrogen
• ATP
• PCR inhibitors

Rainin universal-fit tips are made from virgin polypropylene that has been optimized to perform across a wide array of applications.

• Exceptional purity assures that Rainin tips are completely free of leachables and exogenous additives, such as clarifiers, colorants or mold release agents
• Strong, supple polymer improves flexibility for accurate touch-off
• Excellent clarity
• High chemical resistance
• Autoclavable

Every Rainin universal-fit tip has a thin-walled orifice that reduces the tip surface area to minimize contact with the liquid.

• Thin wall design provides tip flexibility for accurate touch-off
• Elongated, finely tapered tip for accurate aspiration and dispensing
• Narrow orifice for complete touch-off

Unlike other filter types that contain additives that can inhibit enzymatic reactions, Rainin filter tips are made from pure virgin sintered polyethylene. Hydrophobic polyethylene particles prevent aerosols and liquids from being aspirated into the body of the pipette.
