This test is crucial for flexible packaging materials, as it determines […]

The performance of a syringe is not only defined by its ability to hold and deliver medication but also by the force required to move the plunger. Plunger force testing is an essential quality control measure that ensures a syringe operates smoothly and consistently during injections. In this article, we will explore the significance of syringe plunger force testing, the standards involved, and how the MST-01 Medical Syringe Tester plays a vital role in performing this test accurately. What is Syringe Plunger Force Testing? Syringe plunger force testing involves measuring the amount of force required to move the plunger within the barrel of the syringe. This force is crucial because it directly impacts […]

Introduction to ISO 7864 ISO 7864 is an international standard that specifies requirements for sterile hypodermic needles intended for single use. This standard ensures the safety, reliability, and performance of medical needles by covering critical aspects such as dimensions, strength, sharpness, and functionality. Specifically, ISO 7864 addresses needle bonding strength, flow rate through the needle (patency of lumen), penetration force, and drag force for needles. Additionally, it includes provisions for sharps injury protection in accordance with ISO 23908 and requires that the conical socket of the hypodermic needle hub meet the requirements of ISO 80369-1. Needles according to the tubular needle designation must also comply with ISO 9626. The Role of […]

Why Do We Need to Test Film Heat Seal Strength? The wide application of films across industries such as food, pharmaceuticals, and electronics highlights their importance in maintaining product safety and integrity. Packaging films rely on strong, consistent seals to prevent contamination, leakage, or product degradation.Heat seal strength is a critical parameter that determines the durability and reliability of these seals. A weak seal can compromise product quality, while an overly strong seal might lead to unnecessary material waste. Testing film heat seal strength ensures that packaging meets performance and safety standards. What is the Film Heat Seal Strength Test? Film heat seal strength measures the force required to break […]

In the world of surgical sutures, precision and safety are paramount. The ASTM F3014 standard plays a crucial role in ensuring that suture needles can penetrate tissue efficiently without causing unnecessary trauma.  What is ASTM F3014? ASTM F3014 is a standard test method developed by ASTM International for measuring the penetration force of surgical suture needles. It provides a controlled, repeatable way to assess how much force is required for a needle to pierce a standardized medium, simulating human or animal tissue. This test ensures that needles perform reliably in clinical use by: Verifying needle sharpness Preventing excessive tissue trauma Supporting consistent quality across batches Why is Needle Penetration Testing Important? Penetration force directly […]

Introduction Maintaining the tablet break strength of pharmaceutical and other tablet products is crucial to ensure they perform effectively and safely for consumers. A precise understanding of tablet crush resistance is vital, especially in industries where products must withstand storage, packaging, and consumer handling without breaking apart prematurely or remaining too hard to use. Why Tablet Break Strength Matters Whether it’s a vitamin supplement, a cleaning additive, or a pharmaceutical product, tablets must meet specific break strength criteria. If they’re too fragile, they may crumble during transport and storage. If they’re too hard, they might be difficult for consumers to use. Consistent tablet break strength helps maintain product integrity, ensure user satisfaction, and meet regulatory standards. The Role […]

Introduction: Understanding Bread Shelf Life Bread shelf life is a critical factor for both consumers and food manufacturers. A fresh loaf of bread is soft, fragrant, and easy to slice, but over time, it loses these desirable qualities and becomes stale. To ensure quality and extend the shelf life of bread, it is essential to measure bread freshness with precision. This article explores how bread freshness testing can be performed using an advanced texture analyzer for bread, enabling manufacturers to measure and control bread firmness, thus ensuring consistent quality in every batch.
