Barrier Extended Length Reload System

The Barrier Extended Length Reload System is a specialized pipette tip reloading system designed to provide high-volume, clean, and contamination-free pipetting in laboratory environments. It includes barrier (filter) tips in extended length formats to reach into deep or narrow containers, and is packaged in a reloadable format for convenience, waste reduction, and cost efficiency. These tips are compatible with a variety of single and multichannel pipettors.

Specifications:

Tip Type: Extended Length, Filtered (barrier)
Material: Medical-grade polypropylene (tips), polyethylene filter (barrier)
Length: Typically longer than standard tips to reach into tubes, deep wells, or narrow containers
Sterility: Usually sterile, RNase-/DNase-free, pyrogen-free, ATP-free
Packaging: Reload system, usually in stacked trays or towers that can be loaded into reusable racks
Filter Type: Hydrophobic barrier to block aerosols and liquids
Volume Range: Available in various sizes — e.g., 10 µL, 20 µL, 200 µL, 1000 µL
Compatibility: Universal fit with most major pipette brands (e.g., Eppendorf, Gilson, Rainin, Sartorius)
Reload Style: Eco-friendly reload inserts reduce plastic waste compared to pre-racked tips

Uses:

Molecular Biology: Ideal for PCR, qPCR, DNA/RNA extraction, and sequencing, where contamination prevention is crucial
Cell Culture: For sterile liquid transfers in biosafety cabinets or tissue culture hoods
Clinical Diagnostics: Prevents cross-contamination when pipetting clinical or biological samples
Pharmaceutical & Biotech Labs: Used during compound handling, assay prep, or sample analysis
Environmental Testing & Forensics: Prevents false positives from aerosol or sample carryover
