Laboratory Products 17 Customised Linear Guides - A Cost-Effective, Versatile Prototyping Solution
Reliance Precision Mechatronics announces a new customisation capability for its range of miniature linear guides. For designers working on prototyping projects Reliance now holds stock lengths of guides which can be quickly cut to length to suit individual requirements, offering a cost-effective, short lead-time solution for low volumes. Innovation in miniaturisation of products has led to a need for linear motion solutions that offer high speed without compromising rigidity, torsional resistance or life. The Reliance miniature guides operate by two rows of circulating ball bearings mating with a 45 degree Gothic style profile. This gives multi-direction equalisation of force, which enables high velocity motion with low friction. Miniature operating environments dictate minimal clearance settings, and an optional pre-loading of the bearings can be requested in conditions that demand additional stiffness and precision. Further options include variations in carriage sealing systems, lubrication and reinforcement.
Reliance’s aim is to supply standard components that can be integrated seamlessly into existing mechanisms and its range of miniature linear guides follow that philosophy, providing a 'drop in replacement ' product so customers can continue production with minimal down time. The miniature linear guides offer excellent price and performance; all guides are inspected and tested for quality assurance. The new cut-to-length capability means that customers can order small quantities and samples for product trials and prototyping.

The programme starts with an evaluation of your weighing needs, the associated risks and potential regulatory requirements or norms relevant for your industry. With this information, GWP provides clear recommendations for selecting, installing, calibrating and operating the adequate weighing system.
The Reactor-Ready Duo Lab Reactor from Radleys supports two jacketed glass reaction vessels of different or similar volume from 100ml to 5 litres, in series or parallel. Associate Professor, Stefan Bon, from the Department of Chemistry at the University of Warwick has invested in four systems for use within his polymer research team ‘The Bon Polymer Colloids Group’ (BonLab). The Bon Group are leaders in polymer research, focussing on the chemistry and physics of colloidal systems and more complex supracolloidal structures.
Commenting on their research work, Professor Bon said: “We are interested in the synthesis of particles and macromolecules for a better understanding of the interactions involved between molecular and colloidal building blocks and potential macroscopic substrates. It is therefore very important that our technology can be scaled-up for use in industrial applications including sensors, coatings, adhesives, food, personal care, agricultural and biological systems.”
He goes on to say: “We specifically selected Reactor- Ready Duo for use in the synthesis of colloidal dispersions, to carry out emulsion polymerisation processes between -10°C to +90°C. We chose the system because it is convenient and easy to use, as we specifically wanted a system which could save us time, making our routine synthesis more efficient. We also wanted an off-the-shelf system which had standard glassware and components that could be easily replaced or upgraded when necessary.
“Most of our synthesis is low viscosity and waterborne but in the case of fast polymerisation (acrylates) any exotherms can be easily controlled via the excellent temperature control offered by the jacketed vessels.
“Reactor-Ready Duo’s thermofluid manifold system is also very useful. In particular it allows us to run reactions in parallel, whereby we use a single circulator to deliver the same temperature to adjacent vessels, allowing us to easily vary other key experimental parameters.”
