    Wiggens is a manufacturer of high quality laboratory equipment based in Beijing, China. We started out as distributor for laboratory equipment and soon became an exclusive distributor for most reputable lab equipment manufacturers. After being established as a well-respected and highly successful distributor all around China, we made the successful transition from a mere distributor to producing high level laboratory equipment itself.

    Since 2006 we produce top-quality laboratory equipment and, by making use of our well- established distribution network, we were able to quickly establish our products in the domestic market.

    Our two brands Wiggens and ChemVak stand for high quality, long durability, and remarkable performance.

    Wiggens is your general laboratory companion and provides products that can be used in all kinds of laboratory environments. The Wiggens product range entails different kinds of magnetic stirrers and hot plates. It even provides hot plates with integrated stirring functions for an even heat distribution among your solvents. In addition to the magnetic stirrers Wiggens also provides overhead stirrers with diverse characteristics to perfectly match the solvent used. In addition, Wiggens offers homogenizers of different magnitudes as well as a broad range of shakers, multi- purpose heaters and colony counters. As a new feature in the 2014 range Wiggens now also provides incubators and water baths for full temperature control.

    ChemVak on the other hand has been created as a brand specialized in vacuum equipment. Different kinds of vacuum pumps, including chemical-resistant diaphragm pumps and oil-free piston pumps, are complemented by vacuum filtration equipment to form whole filtration systems for a wide range of different applications. In addition, Water-jet aspirator pumps and bio-suction systems are part of the product range.
