Rainin Pipette Tip BioClean Ultra LTS 2000 ul 16 Racks with 60 Tips Each

Rainin 30389236 Removable Cover Racked Tips – 2000 µL, LTS, BioClean Ultra

The Rainin 30389236 (Legacy MFR Part: RT-L2000) is a premium 2000 µL (2.0 mL) large-volume macro pipette tip engineered specifically for Rainin pipettes equipped with the LiteTouch System (LTS). Molded from 100% virgin, bio-inert polypropylene, these non-sterile, non-filtered macro tips utilize the unique cylindrical LTS geometry with a positive-stop design to achieve an absolute, airtight seal with minimal mounting force. Packaged in structural, removable-cover racks, the tips feature the advanced FinePoint thin-walled orifice architecture. Tested and certified under strict BioClean Ultra standards, they are guaranteed free of any detectable RNase, DNase, DNA, ATP, or PCR inhibitors, preserving matrix purity during high-volume sample preparations.

Technical Performance and Design

• LiteTouch System (LTS) Engineering: Unlike conventional universal cone-shaped shafts that require heavy friction jamming, the cylindrical LTS tip slides effortlessly onto the pipette shaft. A built-in internal sealing ring makes an immediate airtight seal with a positive mechanical stop, reducing tip-ejection forces by up to 70%.

• BioClean Ultra Certified Purity: Every manufacturing lot is rigorously audited and certified free of biological contaminants (DNA, DNase, RNase, ATP, proteins, proteases) and manufacturing trace chemicals, ensuring that sensitive molecular biology reagents or enzymatic master mixes remain uncompromised.

• FinePoint Tip Architecture: The ultra-thin, flexible walls taper to a narrow, precisely calibrated orifice. This structural design minimizes fluid surface tension at the apex, facilitating complete sample touch-off and dispensing recovery to optimize volumetric accuracy.

• Bi-Functional Removable Cover Rack: Supplied in robust, stackable polypropylene racks featuring a bi-functional latching lid. The cover can either function as a traditional flip-back hinged lid for rapid one-handed work or lift off entirely to conserve space under crowded laminar flow hoods.

Key Benefits & Applications

• Ergonomic Fatigue Mitigation: The combined LTS tip configuration dramatically reduces cumulative hand, wrist, and thumb strain, actively protecting laboratory staff from Repetitive Strain Injuries (RSI) during extensive high-volume fluid manipulation shifts.

• Large-Volume Buffering & Reagents: The optimized choice for routine preparation of large-volume master mixes, deepwell block filling, serial aliquoting, and general buffer compounding.

• In-House Sterilization Flexibility: Arriving clean and non-sterile, both the virgin polypropylene tips and structural racks are fully optimized to withstand standard autoclave steam cycles (121°C for 20 minutes) if protocols require a sterile barrier.

• Trace-Analytical Safety: The lack of internal chemical lubricants, slip agents, or downstream dyes ensures that no hidden additives leach into biological samples to throw off UV-Vis or chromatography instrumentation.
