MixMate minimizes hand-arm vibration risks
25 Aug 2008Eppendorf MixMate is the first vortexer to be available with independently verified data showing the low transfer of hand-arm vibration during its operation.
EU Directive 2002/44EG addresses the need for regulations protecting employees from hazardous mechanical vibration. Above certain limits, regular and frequent exposure to hand-arm vibration leads to an increased risk of painful and disabling disorders of the blood vessels, nerves, joints and muscles of the hand, wrist and arms, including carpal tunnel syndrome.
Using a vortexing procedure to mix liquids causes transfer of vibration to the hand and arm, so posing a theoretical risk. However, in line with Eppendorf’s ergonomic concept, and with the protection of the user in mind, the actual risk and daily maximum dose of exposure incurred by the Eppendorf mixer MixMate with integrated vortexing function were analyzed and summarized by the independent British institution “Industrial Noise & Vibration Centre”. The results making MixMate the first vortexer for which detailed hand-arm vibration data is available.
Dr. Sabine Kühn, Eppendorf’s MixMate product manager, underlines the importance of the MixMate vibration data: ‘The independent assessment showed a significantly lower level of hand-arm vibration transfer from Eppendorf MixMate compared with a commonly used vortexer from another manufacturer. Our customers can be reassured that MixMate’s optimised 2-dimensional rotating motion not only reduces hand-arm vibration to very safe levels, it also provides rapid, reproducible mixing and vortexing for numerous tube and plate formats.’

MixMate from Eppendorf - a compact and amazingly versatile benchtop mixer
EppendorfCompact and amazingly versatile, benchtop MixMate can be used for virtually any mixing application. It accommodates micro test tubes, PCR plates, deepwell plates and MTPs. It features an integrated vortex ing function and an operating concept that is as simple as it is intelligent. 2DMix-Control: uniquely fast and controlled mixing movement Current findings show that rpm speed is not the only determining factor in efficiently mixing small volumes. More often, the perfect mixing process occurs when parameters such as speed, type of mixing movement (e.g., orbital) and the mixing radius are optimized to smoothly run together. Eppendorf has perfected how these parameters interact in MixMate, and we have named this feature 2DMix-Control. Optimized mixing Perfect mixing radius combined with perfect, 2-dimension mixing and adjustable mixing speed ensure rapid and complete mixing of even the smallest volumes. Anti-spill technology Perfectly controlled 2-dimension mixing prevents spilling and/or lid wetting, eliminating any need for centrifugation after mixing.
