SOCOREX Acurex™ Compact Bottle Top Dispenser Model 501 / 502

Overview

The SOCOREX Acurex™ Compact Bottle Top Dispenser (Models 501 and 502) is an engineered solution for precise, repeatable, and contamination-free liquid handling in space-constrained laboratory environments. Designed according to the principles of positive displacement volumetric dispensing, it operates without reliance on air displacement or piston seals subject to wear—ensuring long-term accuracy and minimal maintenance. Its ultra-low profile architecture integrates the entire fluid path within the reagent bottle neck, eliminating external tubing, valves, or syringe assemblies. This design minimizes dead volume, prevents aerosol generation, and supports stable operation under thermal extremes—whether inside refrigerated storage compartments (4 °C), cold rooms (−20 °C), or water baths (up to 60 °C). Manufactured in Switzerland to ISO 9001-certified quality standards, the Acurex™ platform meets the mechanical and chemical durability requirements of GLP-compliant workflows and routine QC/QA applications across pharmaceutical, academic, and industrial laboratories.

Key Features

• Ultra-compact vertical footprint: Total height adjustable via telescoping scale sleeve—reduced by up to 35 mm for seamless integration into standard laboratory refrigerators and laminar flow hoods.
• Metal-free fluid path: All wetted components constructed from chemically inert polymers—including PTFE sealing elements, FEP-coated plungers, PEEK valve bodies, and ETFE diaphragms—ensuring compatibility with aggressive solvents (e.g., concentrated acids, bases, halogenated organics) and eliminating metallic leaching risks.
• Autoclavable assembly: Entire dispenser body (including scale sleeve, plunger head, and valve housing) withstands steam sterilization at 121 °C for 20 minutes per ISO 17665, supporting aseptic preparation of cell culture media, buffers, and diagnostic reagents.
• Precision-calibrated volumetric delivery: Factory-adjusted to deliver volumes within ±0.1% CV across full range; traceable calibration certificates available upon request (ISO/IEC 17025 accredited).
• Modular bottle compatibility: Pre-configured for four standard glass bottle volumes (250, 500, 1000, 2000 mL) with two material options—amber glass (for light-sensitive compounds) and borosilicate glass (for thermal and mechanical stability).

Sample Compatibility & Compliance

The Acurex™ dispenser accommodates a broad spectrum of aqueous, organic, and viscous liquids—including PBS, ethanol, DMSO, glycerol solutions (up to 80% v/v), and diluted HCl/HNO₃ (≤1 M). Its inert fluid path ensures no measurable interaction with analytes during transfer, preserving sample integrity for downstream applications such as HPLC sample prep, ELISA plate filling, or titrant dispensing. The device complies with key regulatory frameworks: USP Analytical Instrument Qualification (AIQ) guidelines for manual liquid handlers, ASTM E2758–18 for volumetric dispensing accuracy, and EU Directive 2014/30/EU (EMC) for electromagnetic compatibility. It is also compatible with GMP documentation workflows requiring audit trails—when used with serialized lot-controlled bottles and calibrated pipette verification records.

Software & Data Management

As a fully manual, non-electronic instrument, the Acurex™ 501/502 requires no firmware, drivers, or software integration. Volume settings are adjusted mechanically via a precision-machined vernier scale with tactile feedback and engraved markings—eliminating drift, battery dependency, or cybersecurity exposure. Each unit ships with a unique serial number and optional NIST-traceable calibration report (certified per ISO/IEC 17025). Laboratories maintaining electronic lab notebooks (ELN) or LIMS systems may log usage parameters—including batch numbers, calibration dates, and bottle material type—using standardized metadata fields aligned with ISA-88 and ANSI/AAMI HE75 human factors guidelines.

Applications

• Preparation of standardized dilution series for analytical method validation (e.g., ICH Q2(R2)).
• Dispensing of temperature-sensitive reagents (e.g., enzymes, antibodies) directly from chilled or heated bottles without removal from controlled environments.
• High-frequency buffer aliquoting in molecular biology labs—reducing cross-contamination risk through dedicated bottle/dispenser pairing.
• Quality control testing in contract manufacturing organizations (CMOs), where metal-free dispensing is mandated for elemental impurity control (ICH Q3D).
• Teaching laboratories requiring robust, intuitive tools for student training in volumetric technique fundamentals (ASTM D1193 Type II/III water handling, pH standard preparation).

FAQ

Is the Acurex™ dispenser suitable for use with hydrofluoric acid (HF)?

No. While the wetted materials resist most common laboratory chemicals, HF attacks silica-based glass and fluoropolymer surfaces over time. Use only with HF-compatible alternatives (e.g., PFA-lined bottles) and consult SOCOREX technical support before deployment.
Can the same dispenser be reused across different bottle sizes?

Yes—provided the threaded neck interface matches (standard GL45 or GL32). Adapters are available for non-standard bottle threads; contact SOCOREX for compatibility verification.
Does the <0.1% CV specification apply across all temperatures?

The stated CV is validated at 20–25 °C per ISO 8655-3. At sub-ambient or elevated temperatures, viscosity changes may affect delivery consistency; users should perform in-house verification per SOP when operating outside this range.
Are replacement parts available for long-term maintenance?

Yes. Seals, plungers, and valve assemblies are stocked globally and supplied with full part numbers and replacement instructions compliant with ISO 13485 medical device servicing standards.
