Overview
The SOCOREX 155 Glass Syringe is a high-precision, manually operated liquid handling instrument engineered for trace-level volumetric delivery and sampling in analytical, pharmaceutical, and research laboratory environments. Unlike plastic or metal syringes, its all-glass construction—comprising borosilicate glass barrel and plunger—ensures chemical inertness, optical clarity for visual meniscus reading, and dimensional stability across thermal cycles. The device operates on the principle of positive displacement: precise linear displacement of the plunger generates reproducible volumetric output without reliance on air cushions or elastomeric seals. Its design conforms to ISO 8537 (syringes for medical use) and supports GLP-compliant workflows where material compatibility, calibration traceability, and thermal resilience are critical.
Key Features
- Borosilicate glass construction rated for autoclaving at temperatures up to 160 °C—enabling repeated sterilization without degradation of dimensional accuracy or surface integrity.
- Dual tip interface options: standard Luer for glass needle attachment and Luer-Lock for secure stainless steel needle coupling—minimizing leakage risk during high-viscosity or pressurized applications.
- Laser-etched, permanent volume graduations with fine-scale increments (e.g., 0.05 mL for 0.1–1 mL models; 0.2 mL for 0.2–5 mL variants), optimized for parallax-free meniscus alignment under magnification.
- Low coefficient of thermal expansion (< 3.3 × 10⁻⁶ K⁻¹) ensures minimal volume drift across ambient temperature fluctuations (15–30 °C), supporting metrological consistency in regulated settings.
- Plunger seal composed of PTFE-coated glass-on-glass contact—eliminating lubricant contamination and enabling dry operation for solvent-sensitive assays.
Sample Compatibility & Compliance
The SOCOREX 155 exhibits broad chemical compatibility with aqueous solutions, organic solvents (including acetone, chloroform, and ethanol), strong acids (e.g., HNO₃, HCl ≤ 6 M), and bases (e.g., NaOH ≤ 1 M). It is not recommended for hydrofluoric acid or molten alkali metals. All models comply with ISO 7886-1 for syringe performance testing and meet ASTM E542 criteria for volumetric calibration methodology. For GMP-regulated environments, the syringe supports documented calibration using NIST-traceable standards and integrates into audit trails when used with calibrated balance-based gravimetric verification protocols.
Software & Data Management
As a manual, non-electronic device, the SOCOREX 155 does not incorporate onboard electronics or firmware. However, it is fully compatible with digital lab notebook (ELN) systems such as LabArchives and Benchling via manual entry of calibration records, usage logs, and maintenance history. Users may assign unique asset IDs and link each syringe to its corresponding calibration certificate (including date, operator, uncertainty budget, and reference standard ID). When deployed in FDA 21 CFR Part 11–compliant laboratories, the physical logbook or electronic record must include signature fields and version-controlled entries to satisfy ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).
Applications
- Preparation of certified reference materials (CRMs) requiring sub-microliter accuracy in ICP-MS and GC-MS sample introduction.
- Calibration of automated liquid handlers using gravimetric comparison against Class A volumetric flasks.
- Microsampling in pharmacokinetic studies where residual carryover must be eliminated—enabled by full disassembly and solvent-rinse capability.
- Injection into high-pressure liquid chromatography (HPLC) and supercritical fluid chromatography (SFC) systems using Luer-Lock stainless steel needles rated to 600 bar.
- Volumetric standardization of titrants in ISO 9001-certified QC labs, where glass syringes serve as primary transfer devices between stock solution and burette.
FAQ
Can the SOCOREX 155 be calibrated in-house?
Yes—provided the laboratory maintains ISO/IEC 17025 accreditation and uses NIST-traceable balances with ≤ 0.01 mg readability and volumetric standards certified to ISO 1042.
Is the plunger interchangeable between different capacity models?
No—each barrel-plunger pair is factory-matched to ensure compliance with ISO 8537 tolerance classes; interchanging components invalidates calibration.
What is the recommended cleaning protocol before high-purity applications?
Rinse three times with ultra-pure water (≥18.2 MΩ·cm), followed by acetone, then dry under nitrogen purge; avoid ultrasonic cleaning unless validated for specific glass grade.
Does the Luer-Lock interface meet ISO 594-1 mechanical requirements?
Yes—the stainless steel hub and threaded collar conform to ISO 594-1:2015 torque specifications (0.5–0.8 N·m) and axial pull-out resistance (> 30 N).
How often should recalibration be performed per regulatory guidance?
Annually for routine use; prior to first use after autoclaving; and after any impact event—aligned with USP Analytical Instrument Qualification framework.
