Overview
The FORTUNA UNIVERSAL® OPTIFIX® HF Bottle Top Dispenser is a high-integrity, chemically resistant manual liquid handling instrument engineered for precise, repeatable dispensing of aggressive and highly corrosive reagents—including hydrofluoric acid (HF), concentrated mineral acids, organic solvents, and alkaline solutions. Based on positive displacement volumetric principle, it operates via a calibrated, PTFE-coated piston driven by a robust, spring-free mechanical actuator—eliminating metal contact with the fluid path and ensuring long-term stability under harsh chemical exposure. Unlike air-displacement pipettes or basic glass burettes, this dispenser maintains consistent delivery accuracy across its full volume range without calibration drift, even after repeated use with volatile or viscous media. Its fully sealed architecture prevents vapor escape, operator exposure, and cross-contamination—critical for laboratories adhering to OSHA HAZCOM, CLP, and REACH compliance frameworks.
Key Features
- Chemical resistance certified for hydrofluoric acid (HF), nitric acid, sulfuric acid, aqua regia, and halogenated solvents—validated per DIN 58947 and ISO 17025-accredited testing
- PTFE monolithic reservoir cylinder and PTFE-coated piston with dual elastomeric sealing rings ensure zero leaching and minimal adsorption
- Spring-free, all-plastic actuation mechanism eliminates corrosion-prone metal components and enables smooth, tactile volume adjustment
- Graduated scale with clearly marked increments (0.1–2.0 mL minimum graduation depending on model) and engraved reference lines for parallax-free reading
- Interchangeable GL40/GL45 polypropylene (PP) adapters included; PTFE adapters available for HF-specific applications
- 100% leak-proof seal verified at 0.5 bar pressure; meets ISO 8655-3 requirements for volumetric accuracy and repeatability
- Ergonomic handle design with non-slip grip and low-force dispensing action reduces operator fatigue during high-throughput workflows
Sample Compatibility & Compliance
The FORTUNA UNIVERSAL® OPTIFIX® HF is validated for direct contact with Class 1–4 corrosives per GHS classification, including but not limited to: HF (up to 48%), fuming nitric acid (≥90%), oleum, sodium hydroxide (50% w/w), and chlorinated solvents (e.g., chloroform, carbon tetrachloride). It complies with material compatibility standards outlined in ASTM D543 and ISO 15202-2 for fluoropolymer-based labware. The device supports audit-ready documentation per FDA 21 CFR Part 11 when integrated with electronic logbooks, and its traceable serial-numbered construction facilitates GLP/GMP instrument qualification (IQ/OQ/PQ). All models are CE-marked and manufactured in accordance with ISO 9001-certified processes in Germany.
Software & Data Management
As a manually operated, analog volumetric device, the OPTIFIX® HF does not incorporate embedded electronics or firmware. However, its metrological performance supports seamless integration into digital lab ecosystems: volume settings and usage logs can be recorded in LIMS platforms (e.g., LabWare, STARLIMS) or ELN systems (e.g., Benchling, LabArchives) via standardized SOP templates. Each unit ships with a Certificate of Conformance (CoC) referencing traceable calibration against NIST-traceable standards. Optional third-party verification services provide ISO/IEC 17025-compliant calibration reports with uncertainty budgets, supporting regulatory submissions under ICH Q7 and USP .
Applications
This dispenser is routinely deployed in analytical chemistry labs for standard solution preparation (e.g., ICP-MS dilutions, titrant dispensing), semiconductor wafer cleaning process chemistry (HF-based etchants), nuclear fuel cycle laboratories (uranium hexafluoride handling), and pharmaceutical QC for residual solvent analysis. It is also employed in environmental testing labs for EPA Method 300.0 anion analysis and in academic research for controlled reagent addition in Schlenk-line reactions. Its inert fluid path makes it suitable for handling moisture-sensitive reagents (e.g., TiCl₄, AlCl₃) and high-purity standards where metallic ion contamination must be avoided (<0.1 ppb).
FAQ
Is the FORTUNA UNIVERSAL® OPTIFIX® HF compatible with hydrofluoric acid?
Yes—its PTFE reservoir, PTFE-coated piston, and PTFE adapter are specifically engineered for safe, long-term HF handling up to 48% concentration.
What maintenance is required?
No routine lubrication or recalibration is needed. Rinse thoroughly with deionized water after each use; store upright with valve open to prevent seal compression set.
Can I switch between different volume ranges on one unit?
No—each OPTIFIX® HF model is factory-calibrated for a fixed volume range (e.g., 10–50 mL or 20–100 mL); interchangeability requires separate units.
Does it meet ISO 8655 requirements?
Yes—compliant with ISO 8655-3 (volumetric accuracy), ISO 8655-5 (repeatability), and ISO 8655-7 (chemical resistance verification).
How is traceability ensured?
Each unit carries a unique laser-engraved serial number linked to its CoC, calibration data sheet, and manufacturing batch record—fully auditable for FDA, EMA, or PMDA inspections.
