Overview
The Drick DRK-507A Electronic Axial Deviation Tester is a precision metrological instrument engineered for quantitative assessment of axial deviation—commonly referred to as verticality or concentricity deviation—in rigid cylindrical containers. It operates on the principle of high-resolution linear displacement measurement using a calibrated digital indicator mounted on a vertically aligned, motor-assisted rotational carriage. As the sample rotates 360° about its base axis, the probe maintains constant radial contact with the container’s outer surface, capturing real-time positional deviations relative to the ideal vertical reference line. The system computes peak-to-peak axial runout and reports maximum deviation in millimeters with traceable resolution down to 0.001 mm. Designed explicitly for compliance-driven quality control environments, the DRK-507A supports standardized evaluation of bottle geometry critical to high-speed filling, capping, labeling, and packaging line integration—where even sub-millimeter misalignment can cause jamming, seal failure, or label skew.
Key Features
- High-precision linear displacement sensor with 0.001 mm resolution and verified accuracy of ±0.003 mm per ISO/IEC 17025-aligned calibration protocol
- Motorized 360° continuous rotation stage with programmable speed control, ensuring consistent angular sampling density across all measurements
- Adjustable clamping mechanism accommodating container heights from 3 mm to 160 mm and diameters typical of PET, glass, and HDPE bottles
- Integrated digital display with dual-unit readout (mm/mil), zero-reset function, and automatic peak-hold capture for rapid pass/fail verification
- Sturdy cast-iron base and anodized aluminum structural frame engineered for long-term dimensional stability under laboratory or production floor conditions
- No external PC required for basic operation; optional USB interface enables direct data export to CSV for statistical process control (SPC) analysis
Sample Compatibility & Compliance
The DRK-507A is validated for use with rigid, upright cylindrical containers including but not limited to PET non-carbonated beverage bottles (per QB/T 2357–1998), PET carbonated soft drink bottles (per QB/T 1868–2004), and pharmaceutical glass and polymer vials and ampoules (per YBB 00192003–2015 “Method for Determination of Vertical Axis Deviation”). It conforms to the geometric evaluation requirements specified in GB/T 8452–2008 “Glass Bottles — Testing Methods for Dimensional Tolerances”, which defines axial deviation as the maximum radial displacement of the container’s upper rim relative to its base centerline over one full revolution. The instrument satisfies prerequisite mechanical metrology criteria for GLP-compliant laboratories and supports audit-ready documentation when used in conjunction with controlled calibration records and operator logbooks.
Software & Data Management
While standalone operation requires no software, the DRK-507A includes a standard USB 2.0 port enabling connection to Windows-based systems running Drick’s optional QC-Link™ Data Manager v3.2. This application provides timestamped test logging, configurable pass/fail limits per container type, X-bar & R chart generation, and export to Excel-compatible formats. All stored datasets include metadata such as operator ID, date/time stamp, environmental conditions (manually entered), and instrument serial number—supporting traceability requirements under FDA 21 CFR Part 11 when deployed with appropriate electronic signature controls and audit trail configuration. Up to 10 measurement sets may be retained onboard for immediate review without external storage.
Applications
- Quality assurance of blow-molded PET bottles prior to sterilization and filling in beverage manufacturing facilities
- Batch release testing of pharmaceutical primary packaging per YBB standards in contract manufacturing organizations (CMOs)
- R&D validation of mold design iterations for improved neck-to-body concentricity
- Supplier qualification audits where axial deviation directly impacts downstream automation performance
- Root cause analysis of labeling misregistration or cap torque inconsistency linked to container geometry variation
- Internal calibration verification of vision-based inline inspection systems used for 100% container screening
FAQ
What standards does the DRK-507A comply with?
It is designed and verified against QB/T 2357–1998, QB/T 1868–2004, YBB 00192003–2015, and GB/T 8452–2008.
Can the instrument measure tapered or non-cylindrical containers?
No—it is optimized for rigid, nominally cylindrical geometries with uniform cross-sections between base and shoulder; conical or oval profiles fall outside its validated scope.
Is external calibration certification available?
Yes—Drick offers UKAS-accredited calibration certificates (ISO/IEC 17025) upon request, including uncertainty budgets traceable to NIM (China National Institute of Metrology).
Does the device support automated reporting for regulatory submissions?
When paired with QC-Link™ and configured with 21 CFR Part 11-compliant user access controls and electronic signatures, it meets documentation integrity requirements for FDA and EMA submissions.
What maintenance is required to ensure long-term accuracy?
Annual verification using certified gauge blocks and rotary alignment standards is recommended; routine cleaning of the probe tip and clamping surfaces is sufficient for daily operation.
