Thermo Scientific Pipette Tips 20 ul for LTS 10 Racks with 96 Tips Each

Thermo Scientific 3721-RI SoftFit-L Sterile Pipette Tips (20 µl, Reload System)

The Thermo Scientific 3721-RI is a premium, sterile pipette tip designed specifically to match the accuracy and ergonomic performance of the Rainin LTS (LiteTouch System). These 20 µl tips feature the SoftFit-L design, incorporating a cylindrical collar and positive-stop architecture to ensure an airtight seal with minimal attachment force. Delivered in an environmentally friendly reload/refill format, these tips allow for the rapid replenishment of empty hinged racks, significantly reducing plastic waste. When configured with HydroLogix technology, these tips provide a superior low-retention surface, ensuring maximum sample recovery and precision for sensitive molecular biology assays.

Technical Performance and Design

• SoftFit-L / Rainin LTS Compatibility: Engineered with a specialized cylindrical collar that provides a "lock-and-key" fit for Rainin LTS pipette shafts. This reduces tip loading and ejection forces by up to 80% compared to traditional universal tips, preserving the ergonomic integrity of the LiteTouch System.

• HydroLogix Low Retention (Available): Utilizes a proprietary hydrophobic surface treatment that minimizes the binding of DNA, proteins, and viscous liquids to the tip wall. This is essential for high-accuracy pipetting of master mixes, detergents, and high-value reagents.

• Reload Tower System: Designed as a sustainable "refill" solution. The 3721-RI inserts snap directly into existing SoftFit-L hinged racks, reducing overall lab plastic waste by up to 50% compared to purchasing new racks.

• Precision Molded Micro-Point: The ultra-fine tip geometry reduces the surface area at the tip orifice, minimizing "wicking" and droplet formation for exceptional accuracy at the lower end of the 20 µl volume range.
