Rainin Pipette Tips 300 ul LTS Low Retention Filtered - 8 Racks

Rainin 30389162 300 µl LTS Filtered Pipette Tips (Low Retention, Sterile)

The Rainin 30389162 is a high-performance, 300 µl pipette tip designed specifically for the LiteTouch System (LTS). Engineered for maximum liquid handling precision, these tips feature Rainin’s proprietary LR (Low Retention) fluoropolymer technology, which creates a super-hydrophobic internal surface. This ensures that even "sticky" or viscous samples—such as those containing detergents, proteins, or genomic material—are dispensed completely with zero residue. Each tip is equipped with a high-density polyethylene aerosol filter to prevent cross-contamination of the pipette shaft and protect your samples from carryover. Delivered in a sterile, nested-rack format, the 30389162 provides the ultra-low attachment and ejection forces required for comfortable, high-accuracy pipetting in molecular biology and clinical research.

Technical Performance and Design

• LiteTouch System (LTS) Compatibility: Features a cylindrical tip-to-pipette interface that creates a perfect seal with a small contact area, resulting in dramatically lower ejection forces compared to traditional conical tips.

• Low Retention (LR) Surface: The internal walls are chemically treated to reduce sample hang-up, significantly improving volumetric accuracy and reproducibility when handling valuable reagents.

• Aerosol Resistant Filter: The 100% pure polyethylene filter acts as a barrier against liquid and vapor contaminants, making it essential for PCR, forensics, and radiolabeled sample handling.

• Extended Length & Narrow Geometry: Designed to provide easy access into deep microtubes and narrow vessels without the pipette shaft touching the tube walls.

Key Benefits & Applications

• Genomics & Proteomics: The LR surface is ideal for DNA/RNA work and protein assays where sample adhesion to the plastic can lead to significant data error.

• PCR Setup: The aerosol filter is critical for preventing "amplicon carryover," ensuring that DNA from one sample does not contaminate the next via the pipette shaft.

• Ergonomic Workflows: Designed specifically to reduce the risk of Repetitive Strain Injury (RSI) for lab technicians performing hundreds of pipetting cycles per day.

• Sensitive Reagent Handling: Perfect for master mixes, enzyme solutions, and detergents like Triton-X or Tween-20 that normally cling to standard polypropylene.
