The 311DS is an incubator that has an orbital shaker built in it. It features a broad temperature range that makes it perfect for applications that need strict temperature control such as liquid cultures, washing blots, and other shaking applications. It is also uniform and accurate. The incubator has a gasket door with a big viewing area. There are a lot of accessories available. It also has adjustable shelves. The temperature inside the 311DS is regulated by a precise system known as SmartChek™. Electronics are found far from the chamber for protection from any heat-related stress. The integral shaker is sturdy with an orbit of 19 mm. A flat platform that has a non-slip rubber mat and different flask platforms are sold separately. Platforms could hold a maximum of 4 2L and 6 1L flasks. Samples can be checked through the large viewing area of the gasketed door without disturbing the contents of the chamber. The shaker automatically stops when the door is opened.
