Product Description
The CELLTREAT® 229016 is a 20µL low retention filter pipette tip — racked, sterile, and engineered for accurate small-volume pipetting in molecular biology, cell culture, and clinical applications. CELLTREAT Scientific Products Pipette Tips deliver high performance with exceptional value, with a perfected balance between raw materials and manufacturing process resulting in superior low retention. Each pack contains 960 tips across 10 racks of 96 tips, in hinged-lid boxes designed for easy one-handed access, stable stacking, and a secure locking tab.
Superior Low Retention — Maximum Sample Recovery at 20µL At 20µL, even a minimal liquid film retained on the inner tip surface represents a significant volume loss and can meaningfully affect assay accuracy and reproducibility. The 229016 features a smooth, hydrophobic polypropylene interior surface that minimizes liquid adhesion — ensuring near-complete sample delivery on every dispense. This is critical for PCR master mix preparation, enzyme addition, restriction digest setup, qPCR setup, and any protocol where 20µL volume accuracy is essential.
Hydrophobic Surface — Consistent, Accurate Pipetting The smooth, hydrophobic inner surface of the 229016 prevents aqueous samples from clinging to the tip wall — reducing sample-to-sample carryover and improving both accuracy and reproducibility across runs. This is particularly valuable when pipetting viscous reagents, enzyme mixes, or protein-containing solutions where surface adhesion would otherwise cause measurable volume losses.
Integrated Filter — Aerosol and Cross-Contamination Protection The integrated hydrophobic filter barrier prevents liquid aerosols from penetrating the pipette barrel during aspiration — protecting the instrument from contamination and preventing cross-contamination between samples. The filter is positioned to provide maximum headspace at the 20µL fill volume, ensuring the barrier is never compromised even when pipetting to capacity.
Universal Fit — Compatible with All Major Pipette Brands The 229016 tip geometry is engineered for secure, leak-free mounting on pipettes from all major manufacturers including Eppendorf, Gilson, Thermo Fisher, Rainin, Brand, and others — allowing labs with mixed pipette inventories to standardize on a single tip SKU for all 20µL applications.
Molded Volume Reference Markings Reference marks molded directly into the tip body provide a rapid visual confirmation of fill volume — useful during high-throughput pipetting where speed and accuracy must both be maintained without pausing to verify each aspiration.
Ergonomic Hinged-Lid Rack Design Hinged lids are designed for easy one-handed opening, making repeated access fast without putting down the pipette. Stacking lid feature and secure locking tab keep racks stable and organized on the benchtop. Interior support ribs maintain rack geometry and prevent warping.
