Thermo Scientific Pipette Tips 20 ul for Rainin LTS 10 Racks

Thermo Scientific 3721-HR SoftFit-L HydroLogix Pipette Tips – 20 µL (Hinged Rack)

The Thermo Scientific 3721-HR is a high-precision 20 µL pipette tip designed specifically for use with Rainin LTS (LiteTouch System) pipettes. Engineered to provide an ergonomic alternative to OEM tips, the SoftFit-L design ensures a perfect seal and exceptionally low ejection forces, reducing physical strain during repetitive low-volume pipetting. These tips feature the proprietary HydroLogix™ low-retention surface, which prevents sample binding and ensures maximum fluid recovery. Supplied in a robust hinged rack, these tips are certified pure and optimized for sensitive applications such as qPCR, micro-volume DNA/RNA protocols, and protein assays.

Technical Performance and Design

• LTS-Specific Ergonomics: Precision-molded to fit the cylindrical shaft of Rainin LTS pipettes. This interface allows for a secure, leak-proof seal with minimal attachment force, preserving the ergonomic "LiteTouch" functionality of the instrument.

• HydroLogix™ Low Retention Technology: The internal surface of the tip is chemically modified to be ultrahydrophobic. This ensures that "sticky" reagents, enzymes, and master mixes do not cling to the walls, providing superior accuracy for 20 µL volumes.

• Hinged Rack (HR) Convenience: The durable rack features a versatile lid that can be used in a hinged configuration for one-handed access or a lift-off configuration. The rack is designed to be stable and resistant to tipping during multichannel use.

• Low-Volume Precision: Specifically designed for volumes between 2 µL and 20 µL, with a fine-point orifice that allows for precise "touching off" and accurate liquid delivery in 96-well and 384-well formats.

Key Benefits & Applications

• qPCR and PCR Setup: The combination of low-retention and purity makes these tips ideal for preparing master mixes and transferring low-volume templates without cross-contamination or sample loss.

• Ergonomic Safety: Allows labs to utilize the low-force features of their Rainin LTS pipettes, helping to prevent Repetitive Strain Injury (RSI) in high-throughput environments.

• High-Precision Dispensing: Critical for assays where reagents are expensive or limited, ensuring that every microliter of the 20 µL sample is successfully delivered into the reaction vessel.

• Stable Laboratory Workflow: The rigid rack design and consistent tip straightness ensure that multichannel pipettes align perfectly with the target wells every time.
