LGC: Rotary Evaporator of Shanghai Shensheng is performing well all the time and very stable.
Since 2003, Shanghai Shensheng has been providing LGC with lab and pilot rotary evaporators. Over 10 years, the stability and durability of the equipment has been highly recognized at LGC. Until now, the first evaporator bought from Shensheng still function well at LGC.
LGC has strict demands on the cleanliness of the materials. Under a tight schedule of research and production, they require stable and efficient equipments. The stability of rotary evaporator depends on the durability of its seals.
Due to the corrosion of various solvents, as well as high temperature and continuous rotational friction, seals (typically O-rings or oil seals) which play a decisive role in rotary evaporator has a relatively short life span thus need to be disassembled and replaced periodically, therefore affecting the production process. In addition, the entire replacement process is also time-consuming and annoying to the users. Moreover, the seal ring needs vacuum grease to seal, which jeopardizes the cleanliness of the material. Also during operation, the seal ring produces debris out of friction, thus re-contaminated the reacting materials.
Shanghai Shensheng initiated to apply mechanical seal instead of traditional seal structure in rotary evaporator. Oil-free, clean, durable, resistance to friction, corrosion and high temperature of mechanical seal ensure the durability and high performance of sealing system, which totally frees the users from the trouble of stopping production to replace seal.
“Rotary Evaporators of Shanghai Shensheng have great vacuum and stable performance. We never stop using them. These machines always work all the week without any problem. And Shensheng also continuously improves the products to meet our requirment. We highly appreciate that.” – Director of Research Department of LGC
LGC is a global leader in the laboratory services, measurement standards, reference materials, genomics and proficiency testing market places. LGC’s origins can be traced back to 1842 when the Laboratory of the Board of Excise was founded in the City of London to regulate the adulteration of tobacco which was prohibited under the Pure Tobacco Act. LGC provides reference materials, proficiency testing, genomic and analytical products and services which underpin the safety, health and security of the public for customers in the across a number of end markets including Pharmaceuticals, Agricultural Biotechnology, Diagnostics, Food, Environment, Government and Academia. Since privatization in 1996, LGC has significantly expanded its activities. Employee numbers have risen from 270 in 1996 to about 2,600 in 2017, as the company has grown organically and through multiple acquisitions.
