A suture diameter tester measures surgical thread under controlled load to confirm declared USP or metric sizes. This guide covers how the instrument works, absorbable and non-absorbable materials, USP and EP standards, typical measurement procedures, and calibration for reliable quality control.
The 6% Luer connector performance tester is a multi-function instrument that verifies the mechanical and sealing performance of Luer fittings used on syringes, needles, infusion sets, and catheters. It measures liquid and air leakage, separation force, unscrewing torque, stress cracking, resistance to over-torque, and ease of assembly under controlled, repeatable conditions.
This article explains how condom bursting volume and pressure are measured and why the test is essential to condom quality assurance. It describes how a condom burst pressure tester inflates a condom to failure while recording the exact pressure and volume at rupture, and outlines the governing standards including ISO 4074.
A holding power tester measures how long a bonded tape resists a steady shear load—a property distinct from initial tack. The article explains the difference, then covers the test method (ASTM D3654), the role of the instrument and its stations, the importance of temperature control, and how to choose the right equipment.
An initial tack tester measures how quickly and firmly an adhesive grabs a surface under light, brief contact—a property distinct from final bond strength. It also outlines how these instruments work, the factors that affect results, and how to choose the right tester.
This article explains polariscope technology for detecting internal stress in glass via birefringence. It covers working principles, key applications (bottles, pharma, food), manual/digital/automatic systems, industry standards, selection criteria, maintenance, and future AI/IoT advancements, emphasizing quality control and compliance.
The Vertical Axis Deviation Tester measures bottle perpendicularity. Digital models offer precise, automated readings for packaging quality control. Regular calibration ensures accuracy.
Leak and seal strength tester: positive/vacuum principles, burst/creep modes, food/pharma/medical uses, ASTM/ISO/GB compliance, and features like precision, data management, and lab selection.
The HST-H3 heat seal tester accurately sets sealing temperature, time, and pressure for film materials. Widely used in food, drug, and cosmetic packaging, it is often paired with automatic torque testers to verify cap tightness, forming a complete quality control solution for closures and seals.
NJY-H5 is an automatic torque tester for bottle caps, measuring opening and closing torque. It uses robotic gripping, has 0.001 Nm resolution, meets ASTM, and suits food, pharma, cosmetic packaging.
