Grant Instruments (UK) has released details of a testing record set in its environmental life testing lab facility in Cambridge (UK) for continuous operation under extreme conditions. The product involved was one of its popular range of Optima™ circulating water baths.

The baths have clocked up a staggering 20,000 hours of continuous operation at maximum temperature. That equates to nearly 14 years of use in a normal customer environment.

Kevin Hardy, lead engineer on the testing facility said “We set them up, switch them on and let them get on with it. We don’t service them and we don’t even clean them so it a really significant level of abuse. We're looking to find any areas of weakness which we can improve on for that product and the next generation we design”.

Emma Hewson, Product Manager added “Grants business reputation has been built on reliability and durability so the accelerated life testing work with products such as the new Optima™ range is a key part of our product development approach. A couple of years ago we updated our way of working to incorporate a much stronger emphasis on watching how our products perform in early life stage of market launch. As well as testing and endurance, we proactively go out and see how the products are performing with our customers not just in terms of reliability but also in meeting their needs efficiently and effectively”.

The Optima™ range of heated and refrigerated circulating baths are used in research, educational, industrial and clinical labs for a wide variety of applications requiring accurate temperature control.
