Thermo Scientific Pipette Tips 1200 ul fits Rainin LTS 8 Racks with 96 Tips Each

Thermo Scientific 2789-05-HR SoftFit-L Pipette Tips – 1200 uL, Filtered, Low Retention

The Thermo Scientific 2789-05-HR is a specialized, high-capacity 1200 uL pipette tip engineered specifically for use with Rainin LTS (LiteTouch System) pipettes. Belonging to the SoftFit-L family, these tips feature the signature cylindrical collar and positive-stop design that LTS users rely on to drastically reduce attachment and ejection forces. This specific model incorporates advanced Low Retention technology, ensuring that sticky, viscous, or low-surface-tension liquids are completely dispensed without leaving a film on the inner wall. Equipped with a high-efficiency aerosol filter and supplied sterile in convenient hinged racks, the 2789-05-HR is the ideal consumable for demanding molecular biology workflows, genomics, and sensitive PCR applications.

Technical Performance and Design

• Rainin LTS Compatibility: The cylindrical collar fits perfectly onto the LiteTouch shaft, creating a secure, leak-free seal with minimal force. This guarantees exceptional pipetting accuracy while drastically reducing the risk of repetitive strain injuries (RSI) during high-throughput workloads.

• Low Retention Polymer: Molded from a highly hydrophobic virgin polypropylene that actively repels viscous fluids (like glycerol, Triton X-100, and concentrated DNA preparations), ensuring maximum sample recovery and absolute volumetric precision.

• Integrated Aerosol Barrier: The internal filter creates a tortuous path that effectively blocks aerosolized droplets and radioactive particles from entering the pipette barrel, actively preventing sample-to-sample cross-contamination.

• Certified Clean: Manufactured under strict cleanroom conditions and certified to be free of detectable DNase, RNase, human DNA, ATP, and endotoxins, safeguarding the integrity of your most sensitive assays.
