Grant Instruments (www.grant.co.uk), a world-renowned supplier of scientific, life sciences and data acquisition products, has introduced a heavy duty microprocessor controlled 3-in-1 multi-functional orbital platform shaker, designed for use in biotech, biopharmaceutical and academic research laboratories. The latest addition to the Grant-bio product range, the PSU-20 platform shaker combines three mixing functions – orbital motion, reciprocation and vibration – into one easy to use benchtop unit. Following on the success of the smaller PS-M3D system, the first platform shaker to offer the three programmable shaking modes, the PSU-20’s mixing functions are fully programmable and can be set for continuous or timed operation (1 min to 96 hours) to achieve optimum mixing either in a single mode or in any different combination of the three functions. The Grant-bio PSU-20 provides unparalleled flexibility as it is available with a range of interchangeable platforms to accommodate different sized flasks, beakers, Petri dishes and other laboratory vessels. One available option is a high-capacity four level ‘hotel’ format platform (480x380mm) which maximises use of bench or floor space. “The PSU-20 is a highly-flexible and competitively-priced multi-functional, multi-platform shaker which enables optimisation of shaking for a wide variety of applications, increasing the yield and improving reproducibility,” says Rob Thorburn, commercial manager for Scientific Products at Grant. “Its versatility means that it’s ideal for multi-user laboratories, particularly for micro and molecular biologists working with microbiological fermentations in warm rooms, multiple gel destaining and membrane processing.” The Grant-bio PSU-20 benchtop unit measures 140 x 485 x 520mm, features a loading capacity of 15kg, a 2-line 16 character LCD display and a powerful, reliable and exceptionally quiet motor. As with all of the Grant-bio range of life science products, the PSU-20 is robust and reliable and comes with a 2-year warranty.
