Hirschmann Ceramus Classic Trace Analysis Bottle Top Dispenser 9310001

Overview

The Hirschmann Ceramus Classic Trace Analysis Bottle Top Dispenser 9310001 is a precision-engineered manual liquid handling instrument designed for high-accuracy volumetric dispensing in trace-level analytical workflows. Built upon the proven Ceramus platform, it integrates a chemically inert ceramic piston and PTFE-sealed valve system to ensure long-term stability, minimal carryover, and exceptional resistance to aggressive solvents—including concentrated acids, bases, and halogenated organics. Its operating principle relies on positive displacement via a calibrated glass syringe barrel and ceramic plunger, eliminating dependence on gravity or liquid density—making it suitable for viscous, volatile, or low-surface-tension media where air-displacement pipettes fail. The device is optimized for ISO/IEC 17025-compliant laboratories performing trace metal analysis (e.g., ICP-MS, ICP-OES sample preparation), environmental testing (EPA Methods 200.8, 6020B), and pharmaceutical residual solvent quantification per USP .

Key Features

• Ceramic piston and ceramic/PTFE valve assembly ensures zero metal leaching and chemical compatibility with >99% of laboratory reagents, including HF, aqua regia, and piranha solution.
• Calibrated borosilicate glass syringe barrel with laser-etched volume scale (0.2–60 mL) and 0.05 mL minimum increment for fine-grained control in sub-milliliter dispensing tasks.
• Integrated ergonomic lever mechanism with dual-stage actuation: coarse adjustment for rapid volume setting and fine-tuning knob for ±0.01 mL resolution.
• Autoclavable (121°C, 20 min) and fully disassemblable for cleaning and validation—critical for GLP/GMP environments requiring documented cleaning procedures.
• ISO 8536-3 and DIN EN ISO 8655-3 compliant calibration certificate available upon request; each unit undergoes individual gravimetric verification at three points across its range (10%, 50%, 90% of max volume).

Sample Compatibility & Compliance

The Ceramus Classic 9310001 supports direct mounting onto standard GL45 and GL32 threaded reagent bottles (including HDPE, LDPE, and borosilicate glass). Its all-ceramic wetted path eliminates adsorption artifacts common with polymer-based dispensers—essential when handling ng/L-level standards for elemental analysis. It complies with ISO/IEC 17025 requirements for measurement traceability, supports audit-ready documentation per FDA 21 CFR Part 11 when used with validated electronic logbooks, and meets the mechanical durability criteria outlined in ASTM E2758 for manual volumetric dispensers. No external power supply or compressed gas is required—ideal for fume hood integration and Class 100 cleanroom use.

Software & Data Management

As a manually operated instrument, the 9310001 does not incorporate embedded electronics or firmware. However, its design enables seamless integration into digital lab workflows: volume settings are recorded directly into LIMS or ELN systems via standardized SOP templates. Calibration data—including gravimetric test reports, uncertainty budgets (k=2), and operator signatures—can be archived in accordance with ISO/IEC 17025 clause 7.7. For labs implementing paperless validation, Hirschmann provides editable PDF calibration certificates compatible with electronic signature platforms compliant with FDA 21 CFR Part 11 Annex 11 requirements.

Applications

• Preparation of certified reference material (CRM) dilutions for ICP-MS calibration curves (e.g., NIST SRM 3100 series).
• Accurate dispensing of internal standards (e.g., Rh, In, Bi) in multi-element trace analysis workflows.
• Controlled addition of derivatization reagents in GC-MS analysis of polar analytes (e.g., underivatized amino acids).
• Standardized acid digestion protocols per EPA Method 3050B and ISO 11466 for soil and sediment samples.
• QC/QA checks in clinical toxicology labs performing heavy metal screening (Pb, Cd, As) in whole blood and urine matrices.

FAQ

Is the 9310001 suitable for hydrofluoric acid (HF) dispensing?
Yes—the all-ceramic piston and PTFE/FFKM valve seals provide full compatibility with aqueous HF solutions up to 48% concentration.
Can the dispenser be recalibrated in-house?
Yes—Hirschmann supplies a traceable calibration kit (Cat. No. 9310010) with NIST-traceable weights, distilled water, and step-by-step SOPs aligned with ISO 8655-6.
What bottle thread sizes does it support?
GL45 (standard for 1–4 L reagent bottles) and GL32 (for 500 mL amber bottles); adapters for GL25 and GL18 are available as optional accessories.
Does it meet ISO 8655 certification requirements?
Each unit is supplied with a factory calibration report referencing ISO 8655-3; full compliance with ISO 8655-6 for user-performed verification is supported via documented procedures.
How often should maintenance be performed?
Visual inspection and functional check before each use; full disassembly, cleaning, and seal replacement recommended every 6 months or after 5000 actuations—whichever occurs first.
