Precision Shrinkage Testing for Pharmaceutical SealsDesigned to meet demanding QC requirements, this Digital Shrinkage Tester evaluates the shrinkage properties of heat-shrink tamper-evident seals for pharmaceuticals. Controlled heating, high-accuracy measurement, and adjustable test parameters ensure consistent, reliable results-helping manufacturers maintain compliance and package integrity.
Safety and Compliance for Peace of MindBuilt-in safety features like a thermal cut-off switch and automatic shutoff at excess temperatures protect both operator and product. Adhering to ASTM and ISO standards, the tester is a trusted tool for pharmaceutical quality assurance. Factory calibration and easy in-field recalibration support continued accuracy.
User-Friendly Operation and Flexible ReportingThe digital interface simplifies setup and monitoring. Test progress is displayed on a large LCD, and test reports can be printed directly via the RS232 port. The adjustable holder supports various seal sizes, and up to three specimens can be analyzed per cycle for efficient workflow.
FAQ's of Shrinkage Testing of Heat-Shrink Tamper-Evident Seals for Pharmaceutical Products:
Q: How does the Digital Shrinkage Tester ensure accurate measurement of seal shrinkage?
A: The tester uses a microprocessor-based digital control system and a PID managed heating element to maintain precise temperature stability. Measurement accuracy is ensured with a 0.5 mm tolerance and resolution down to 0.01 mm, allowing for reliable and reproducible results.
Q: What types of tamper-evident seals can be tested with this equipment?
A: This instrument accommodates heat-shrink tamper-evident seals used in pharmaceutical packaging. The adjustable stainless steel fixture allows for specimen diameters from 10 to 50 mm and lengths from 20 to 120 mm, covering common pharmaceutical seal sizes.
Q: When should I calibrate the Digital Shrinkage Tester?
A: The tester comes factory calibrated for immediate use. For ongoing accuracy, in-field recalibration is recommended periodically based on your internal QC policy or whenever accuracy verification indicates a deviation.
Q: Where is the Digital Shrinkage Tester best placed for operation?
A: It is designed for benchtop mounting in environments free from corrosive gases and strong vibrations. An ambient temperature range of 15-35C with 35-85% relative humidity supports optimal operation.
Q: What is the testing process for seal shrinkage?
A: Place up to three seal specimens in the adjustable stainless steel fixture. Set test parameters, including temperature (up to 250C) and speed (10-200 mm/min). The tester measures shrinkage along a 0-100 mm stroke, and data is displayed and can be printed via the RS232 port.
Q: How can I benefit from using this shrinkage tester in pharmaceutical QC?
A: By ensuring seals shrink and perform as intended, this device helps maintain packaging integrity and product safety. Digital automation, high reliability, and compliance with ASTM/ISO standards streamline testing processes and regulatory adherence.
Q: Is data output and reporting supported on this device?
A: Yes, the Digital Shrinkage Tester includes an RS232 serial interface, allowing printable reports and easy data transfer for documentation and analysis.
