Syringe compression force testing is crucial for ensuring the quality, safety, and functionality of medical syringes, which are essential for various healthcare applications. This test helps assess the forces involved when a syringe plunger moves inside the barrel, ensuring that the device performs as expected under normal operating conditions. In this article, we will delve into the syringe compression force test, including its importance, the methodology, and relevant standards such as ISO 11040-4. What is Syringe Compression Force Testing? Syringe compression force testing evaluates the mechanical behavior of a syringe as the plunger moves within the barrel. The test measures the amount of force required to push the plunger, simulating […]

Board bursting testers are specialized instruments used to measure the maximum pressure a board (such as corrugated, fiberboard, or other sheet-like materials) can withstand before failure. This article explains the purpose of these testers, their working principles, and what to consider when buying one. What Is a Board Bursting Tester? A board bursting tester (often known as a burst strength tester) is designed to evaluate the resistance of a board to rupture under increasing pressure. By applying a steadily increasing force—typically via a hydraulic or pneumatic system—the tester determines the point at which the board bursts. This measurement is essential for quality control, ensuring that boards used in packaging, construction, and other […]

Introduction In the competitive world of pharmaceutical manufacturing, maintaining consistent product quality is not just a requirement—it’s a necessity. From tablet hardness to the adhesiveness of transdermal patches, physical characteristics directly impact the efficacy and safety of medications. Cell Instruments’ TEX-01 Texture Analyzer offers an innovative solution for precise physical property testing of pharmaceutical products, empowering professionals in R&D and QA/QC departments to refine formulations and uphold strict standards. Why Physical Properties Matter in Pharma Drug effectiveness isn’t only about chemical composition—it’s also influenced by texture-related attributes such as hardness, cohesion, and adhesiveness. For instance, a fast-dissolving tablet must demonstrate both structural integrity during handling and rapid breakdown in the digestive tract. Similarly, transdermal patches need […]

Introduction Understanding the texture of popcorn is crucial for ensuring consumer satisfaction. Popcorn texture analysis allows manufacturers and food processors to assess the crunchiness and consistency of different cooking methods. By utilizing the shear cell method, it becomes possible to standardize popcorn quality control, helping brands optimize their production and home-cooking recommendations. Testing Popcorn Crunchiness: Methods and Procedure Sample Preparation Two common cooking methods were tested: After cooling, samples were placed in a shear cell for testing. The shear cell method mimics the biting process, providing an objective measure of crunchiness. Testing Parameters A Texture Analyzer with a load cell was used to apply force to the popcorn samples. The test was performed at: Benefits of Popcorn Texture Analysis for Quality Control

This […]

What Is Melt Flow Testing? Melt flow testing is a standardized method used to measure the rate at which a polymer, in its melted state, flows through a specific die under a set load and temperature. Essentially, this test provides a quick, repeatable way to gauge a polymer’s viscosity and processability. Melt flow testing measures the flow of a polymer when it is melted. The result, known as the melt mass-flow rate (MFR) or melt volume-flow rate (MVR), quantifies the amount of polymer mass or volume that flows through a small die under specified temperature and pressure conditions. The melt flow test itself is simple and straightforward. A small amount of […]
