Cytiva Allegro™ Single-Use Fill Needles – Pack of 12, 0.8 mm Luer Lock

Overview

The Cytiva Allegro™ Single-Use Fill Needles are precision-engineered, pre-sterilized fluid path components designed for aseptic liquid dispensing in biopharmaceutical final fill operations. Unlike reusable stainless-steel needles requiring rigorous cleaning validation, process qualification, and periodic integrity testing, the Allegro needle delivers a fully disposable, ready-to-use solution that eliminates post-use reprocessing entirely. Each needle integrates a stainless-steel-reinforced polyetheretherketone (PEEK) shaft—ensuring dimensional stability, mechanical rigidity, and resistance to deformation under high-pressure dispensing—and a polypropylene hub with integrated silicone O-ring for secure, leak-tight mounting into standard fill heads. The 0.8 mm inner diameter (ID) luer lock configuration is optimized for low-volume, high-accuracy filling of vials and syringes containing sensitive biologics—including monoclonal antibodies, viral vectors, and mRNA-based therapeutics—where metal leaching, particulate generation, and endotoxin carryover must be rigorously controlled.

Key Features

• Pre-sterilized single-use design: gamma irradiated (≤50 kGy) or steam autoclaved (130°C, 75 min), supplied in ISO Class 8 cleanroom-manufactured packaging with full traceability
• Stainless-steel-reinforced PEEK shaft: maintains straightness and column stability during high-speed bottom-up filling; prevents droplet formation and ensures volumetric accuracy
• USP Class VI–compliant materials: all product-contact surfaces meet USP <661.1> (plastics), <85> (bacterial endotoxins), and <788> (particulate matter) requirements
• Laser-marked identification: each needle bears permanent laser etching of product code and batch number for full production history traceability
• O-ring–integrated hub: prevents axial slippage during operation and ensures consistent seating pressure across repeated cycles
• No pre-rinse or drying required: validated non-pyrogenic and low non-volatile residue (NVR <1 mg per needle after extraction)
• Controlled wall thickness and ID tolerance: supports repeatable flow dynamics and minimizes shear stress on shear-sensitive formulations

Sample Compatibility & Compliance

Allegro needles are qualified for use with aqueous, buffered, and low-viscosity biopharmaceutical liquids—including protein therapeutics, vaccines, blood-derived products, and clinical trial batches. Their inert PEEK/stainless-steel composite construction avoids catalytic degradation or metal ion leaching common with bare stainless-steel systems—making them suitable for formulations with free thiol groups or oxidation-prone excipients. All units undergo comprehensive quality control per ISO 9001–certified protocols, including dimensional verification (±0.05 mm tolerance on critical features), luer lock leak testing (≤0.1 mL/min at 3 bar), hub integrity assessment, and extractables profiling per USP <1031>. Batch-specific Certificates of Analysis (CoA) and Certificates of Conformance (CoC) are provided, documenting compliance with USP <788>, <85>, <661.1>, and ISO 14644-1 Class 8 environmental controls. The system supports GLP/GMP-aligned documentation workflows and is compatible with FDA 21 CFR Part 11–enabled electronic record systems when paired with validated fill line software.

Software & Data Management

While the Allegro needle itself is a passive hardware component, its integration into automated fill lines enables robust data capture via host SCADA or MES platforms. Each laser-marked batch identifier allows direct linkage to sterilization logs, CoAs, and stability data within enterprise quality management systems (QMS). Cytiva provides supporting documentation packages—including validation support files, material compatibility matrices, and sterilization cycle equivalence reports—for inclusion in regulatory submissions (e.g., IND, BLA, MAA). For customers operating under Annex 1 or ICH Q5C guidelines, Cytiva offers supplementary data packages addressing extractables/leachables (E&L), particulate shedding under dynamic flow conditions, and long-term storage stability (up to 36 months from manufacture date under recommended conditions: 2–40°C, dry, protected from UV).

Applications

• Final aseptic filling of vials, syringes, and cartridges in commercial and clinical-scale biomanufacturing
• High-potency drug substance (HPAPI) filling where stainless-steel corrosion or surface adsorption poses contamination risk
• Modular integration into Allegro-based single-use systems—including feed bags, buffer tanks, Kleenpak™ sterile connectors, and tubing assemblies
• Rapid changeover for multi-product facilities handling diverse clinical trial batches without cross-contamination concerns
• Bottom-up filling of lyophilization-ready formulations requiring precise volume delivery and minimal foaming
• Fill-finish operations subject to stringent regulatory oversight (FDA, EMA, PMDA) where cleaning validation burden reduction is a strategic priority

FAQ

Are Allegro needles compatible with standard luer lock fill heads?
Yes—the 0.8 mm variant features a standardized ISO 594-1 luer lock interface and has been validated for mechanical and functional interoperability with major OEM fill platforms including Bausch+Ströbel, IMA, and Bosch.
Can these needles be used for both gamma and autoclave sterilization?
Yes—each batch is qualified for either terminal gamma irradiation (≤50 kGy) or saturated steam autoclaving (130°C, 75 minutes, single cycle); dual-sterilization is not recommended.
What is the maximum recommended operating pressure?
The reinforced PEEK shaft is rated for continuous operation up to 6 bar (87 psi) at 25°C; transient peaks up to 10 bar are permissible for ≤5 seconds per fill cycle.
Do Allegro needles require pre-rinsing before first use?
No—units are supplied ready for immediate installation and use; no pre-rinse, drying, or depyrogenation steps are necessary.
How is lot traceability ensured?
Each needle is individually laser-marked with a unique alphanumeric code linked to full manufacturing, sterilization, and QC records stored in Cytiva’s global quality database.
