Rainin Pipette Tips Green-Pak LTS 250 ul 20 Racks

Description

Rainin Green-Pak SpaceSaver LTS Pipette Tips – 250 µL, Low Retention, Sterile (MPN: 30389302)

The Rainin 30389302 (manufactured by Mettler Toledo) is a premium, high-efficiency pipette tip refill matrix engineered for precise low-volume liquid handling. Part of the innovative Green-Pak™ SpaceSaver™ ecosystem, this nested, stacked refill tower is designed to rapidly replenish empty Rainin hinged-lid tip racks while reducing environmental plastic waste by 80% compared to conventional single-rack packaging. Molded from ultra-pure virgin polypropylene, these 250 µL tips feature a superhydrophobic, low-retention surface chemistry that minimizes sample binding from viscous or high-surface-tension liquids. Tailored exclusively for Rainin pipettes equipped with the LiteTouch™ System (LTS), the cylindrical tip geometry ensures a consistent, low-force airtight seal and smooth mechanical ejection.

Technical Performance and Design

• LiteTouch™ System (LTS) Fitment: Specifically engineered with a positive-stop cylindrical shoulder designed exclusively for Rainin LTS pipettes. This profile reduces tip loading and ejection forces by up to 85%, significantly lessening hand and wrist fatigue during high-repetition liquid handling protocols.

• Superhydrophobic Low-Retention Surface: Modifies the internal polymer surface to repel fluids. This minimizes the retention of valuable or sticky target materials (such as concentrated enzymes, protein suspensions, genomic DNA, and master mixes), yielding exceptional volumetric accuracy and repeatability.

• Eco-Conscious SpaceSaver™ Stack: Delivers a compact tower design containing 10 nested layers of 96 tips. The sleeve shell allows a technician to drop a full, aligned 96-tip deck into an empty rack in seconds without ever touching the individual polymer tips.

• BioClean Ultra™ Purity Certification: Manufactured via a fully automated cleanroom assembly process to guarantee human-contact-free production. Every lot is thoroughly audited and certified free of detectable RNase, DNase, human DNA, endotoxins (pyrogens), proteases, and PCR inhibitors.

Key Benefits & Applications

• High-Accuracy Protein & Enzyme Assays: The low-retention matrix eliminates sample hang-up inside the tip orifice, maintaining low coefficients of variation (%CV) during low-volume enzyme kinetics and ELISA distributions.

• Genomics & qPCR Setup: The BioClean Ultra certification guarantees a pristine fluid path completely free of cellular nuclease artifacts, protecting target DNA templates during downstream amplification preparation.

• Bench Space Optimization: The compact SpaceSaver stack requires up to 70% less physical storage space on laboratory shelving units and stockroom drawers compared to 10 separate traditional single racks.

• Rapid, Ergonomic Reloading: The top-loading guide chassis ensures immediate mechanical orientation alignment over an empty rack shell, keeping user workflows fast and uninterrupted.
