Gels and hydrocolloids such as agar, gelatin, xanthan and guar gum, etc. are widely used in the food, cosmetics/personal care, and medical/pharmaceutical industries.

In the food industry, gels are frequently used as a binding agent, whipping agent, thickening, stabilizer and adhesive. In the cosmetics and personal care industry gels are used in products such as shower & shaving gels, face creams, shampoos & conditioners, foundations, toothpastes, and sunscreens. They are also key ingredients in the manufacture of medical and pharmaceutical products e.g. ointments & lubricants, contact lenses, gel capsules, wound dressings and suppositories. Hydrogel polymers are even used in coronary stents because their consistency resembles living tissue.

Mecmesin force and torque testing systems are used to precisely quantify textural characteristics such as gel strength, elasticity and rupture force, which are all key to controlling the function and quality of these ingredients. For example, gelatin manufacturers and end-users use texture analyzers to measure gel strength, a key indicator of quality. The industry-standard test method is 'Bloom strength' and is used to grade the gel concentration, from which the product price is often set based on this grading.

Mecmesin has a dedicated range of texture analysis fixtures, designed exclusively for gel and hydrocolloid testing, conforming to key standards such as ISO 9665, GME and AOAC 1985.

Mecmesin OmniTest machine demo by the Duchess of Sussex at University of Chichester Tech Park opening

The Duke and Duchess of Sussex officially opened the University of Chichester’s new Engineering and Digital Technology Park on 3rd October 2018. Part of the tour of the £35million development, based at the Bognor Regis campus, was a visit to the Department of Engineering and Design. The laboratory features several Mecmesin force measurement machines, notably a 50 kN OmniTest Universal Testing Machine (UTM); a state-of-the-art software-controlled materials testing system.

Methods of force and torque testing for food packaging quality

Packaging solutions for food are incredibly diverse; in all aspects of physical design, mechanical function and aesthetic appeal. Their purpose is more straightforward: be safe, secure, yet easy to open, close or reliably re-seal; dispense cleanly and efficiently; minimise loss and waste; maximise shelf life; be cost-effective to manufacture and ultimately recycle or dispose of. Add to that, the consumer desire for attractive and innovative new designs, and the straightforward ultimate purpose can become quite involved in terms of meeting each individual challenge.

Mecmesin white paper: Force testing in medical tubing

Plastic medical tubing is central to the provision of effective health care in the 21st century. It is essential for the delivery of blood, nutrients and gases to the patient, and for the execution of minimally invasive surgical procedures such as cardiac angioplasty, which have proliferated widely over recent years. This article examines four force testing procedures for plastic medical tubing and explores the benefits and methodological considerations of each.

Universal testing machine range (0.5 - 5 kN)

Mecmesin offers a wide range of universal testing machines (UTM) for tension and compression testing. At the top end, our MultiTest-i systems are driven by the powerful Emperor™ control and analysis software on a separate PC, while our production-level testers in the MultiTest-xt series offer touch-screen ease of use and rapid processing. All of these systems give fully programmed control and accurate, repeatable testing, with test libraries for instant recall.
