* Applicable in life-science, pharmacy, medical science, chemistry, biology, and related fields for storage of samples which need a constant temperature and for incubation
* Digital temperature display and control
* PID controller for temperature stability and safety protection
* Stainless steel shelves
* Very good heating characteristics
* Ecologically friendly
* Easy to clean
* Timer function
* Heating function start and duration can be pre-set
* Temperature control programs: Temperature programs can be divided into 9 ections and for every section temperature and duration can be set individually
* 3 pre-set often used temperatures
* Can be  opened anytime when necessary
* Temperature measure unit can be set as either °C or °F
* When the temperature exceeds set levels and reaches the set safety value, an alarm activates, power is cut  off, and the incubation process stops
* A professional controller adjusts the circular fans inside and regulates the defrosting cycle
* An observation window made of tempered glass is installed, which makes the examination of samples easy and convenient, and which does not lead to unnecessary disruptions of the incubation process
* The magnetic door and high-quality gasket can absorb external shocks and compriseexcellent sealing characteristics
* The stainless steel shelves have a good air permeability, are easy to clean and can be adjusted in height
* When temperature deviation occurs, the BIAS function sets in, which makes operation convenient
* For the case of an unexpected power breakdown the incubator offers two working options: Automatic re- operation and automatic stop
* When opening the incubator, a light turns on, and the fan and heating device stop operation. After one minute without closing the door an alarm sets in
* The WH-11CA and the WH-21CAincubators use heat transfer method for circulation. In aseparated room outside the work space it uses heat exchange, in the working space it usesnatural convection and forced circulation
* The circulation method will not induce air pollution and can guarantee exact temperaturedistribution
* Software for temperature control is optionally available

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. In 2014, a new line of gas generators became part of the ChemVak product line and round out the picture of ChemVak as a specialist for vacuum and gas related operations.
