FORTUNA OPTIFIX® SAFETY S Bottle Top Dispenser

Overview

The FORTUNA OPTIFIX® SAFETY S Bottle Top Dispenser is a precision-engineered manual liquid handling instrument designed for safe, repeatable, and metrologically traceable dispensing of aggressive and highly corrosive reagents—including concentrated hydrochloric acid, nitric acid, sulfuric acid, and other halogenated or oxidizing solutions. Built on the principle of positive displacement via a calibrated glass cylinder and PTFE-coated piston assembly, it eliminates reliance on elastomeric diaphragms or metal springs that degrade in acidic environments. Its all-PTFE wetted path—including valves, adapters, delivery tip, and sealing elements—ensures long-term chemical compatibility without leaching, swelling, or performance drift. The device operates under ambient pressure and requires no external power source, making it ideal for fume hood–based workflows where spark-free operation and intrinsic safety are mandatory.

Key Features

• Chemical resistance validated for prolonged exposure to ≥37% HCl, ≥65% HNO₃, and aqua regia—no metal components in fluid path; stainless steel is excluded entirely from critical sealing zones
• H-certified calibration per German national metrological standards (Physikalisch-Technische Bundesanstalt, PTB), with individual serial-numbered certification documents traceable to SI units
• Optimized piston geometry with laser-etched scale markings on borosilicate glass cylinder—permanent, solvent-resistant, and readable from multiple angles
• Dual-stage safety system: integrated pressure-relief valve with exhaust tube prevents over-pressurization during bottle venting; secondary mechanical stop limits piston travel beyond calibrated range
• Ergonomic PP finger guard with dual-thumb grip design—fully ambidextrous and compatible with standard lab gloves (nitrile, neoprene, or butyl)
• Modular GL32 thread interface with two interchangeable PTFE adapters (40 mm and 45 mm) and one chemically inert PTFE delivery tube—enabling rapid adaptation across common reagent bottle neck sizes
• Zero-metal spring architecture: actuation force is transmitted exclusively through reinforced polymer linkages and self-lubricating PTFE bushings

Sample Compatibility & Compliance

The OPTIFIX® SAFETY S meets stringent regulatory requirements for analytical and quality control laboratories operating under GLP, GMP, and ISO/IEC 17025 frameworks. Its construction adheres to DIN EN ISO 8655-3 for volumetric accuracy of manual dispensers, with volume deviation certified at ±0.2% (for 0.4–2 mL ranges) and ±0.6% (for 20–100 mL ranges). Each unit undergoes individual gravimetric verification using NIST-traceable weights and Class A distilled water prior to shipment. The absence of metallic parts ensures full compliance with USP for extractables profiling in pharmaceutical reagent preparation. Documentation includes full traceability to PTB reference standards, batch-specific calibration reports, and conformity declarations aligned with EU Regulation (EC) No 765/2008.

Software & Data Management

As a fully mechanical, non-electronic instrument, the OPTIFIX® SAFETY S does not incorporate onboard software or digital interfaces. However, its metrological integrity supports seamless integration into electronic laboratory notebooks (ELN) and LIMS environments through standardized SOP documentation and manual entry protocols. Calibration records—including date, operator ID, verification method (gravimetric per ISO 8655-6), and tolerance verification results—are structured to satisfy FDA 21 CFR Part 11 audit requirements when maintained in controlled document management systems. Optional calibration log templates (PDF/Excel) are available upon request for GLP-compliant record retention.

Applications

• Precision dispensing of concentrated mineral acids in titration standardization and buffer preparation
• Controlled addition of corrosive catalysts (e.g., AlCl₃ in chlorinated solvents) in synthetic chemistry workflows
• Reagent delivery in ICP-MS sample introduction systems where metal-free pathways prevent spectral interference
• Quality control testing of industrial cleaning agents and etchants requiring exact volumetric dosing
• Teaching laboratories emphasizing metrological rigor and hazard-aware liquid handling techniques

FAQ

Is the OPTIFIX® SAFETY S suitable for hydrofluoric acid (HF)?

No—HF attacks both borosilicate glass and many PTFE formulations. For HF applications, consult FORTUNA’s dedicated HF-safe dispenser series with fused silica cylinders and enhanced fluoropolymer seals.
Can the dispenser be autoclaved?

No—glass cylinders and PTFE components are not rated for steam sterilization. Cleaning is performed via solvent rinsing (e.g., acetone, isopropanol) followed by air-drying in a fume hood.
What maintenance is required to sustain accuracy over time?

Annual recalibration is recommended per ISO/IEC 17025 guidelines. Users should inspect piston seal integrity visually before each use and replace PTFE seals every 12 months under continuous operation.
Does the device comply with ISO 8655 for all volume ranges?

Yes—each volume range (0.4–2 mL, 2–10 mL, 10–50 mL, 20–100 mL) is independently verified per ISO 8655-3 Annex B, with uncertainty budgets reported in the certificate of calibration.
Are replacement parts available separately?

Yes—original FORTUNA PTFE pistons, glass cylinders, GL32 adapters, and safety valves are stocked globally with lead times under 5 business days. All spare parts carry identical H-certification and traceability documentation.
