D400W vacuum drying oven (400W) is designed for drying heat sensitivity, easily decomposed and easily oxidizing material, especially for drying some complicated ingredient materials. Working room is made from stainless steel, its square shape has a wider using space than circular shape.
The built-in microcomputer processor make use of electric signal which is generated by feedback value on-off to control the heating element, through PID self-tuning(manual adjustment is available), amended parameter will automatic locking and the correct signal constants the temperature within setting range, after the temperature buffer is stable, temperature difference is lower than ±1℃ under normal pressure and vacuum pressure. Front panel’s “vacuum meter” displays the vacuum degree of working room. Special purpose bleeder valve can pump air and do vacuum drying. Other switches and control device are also set in the front panel, which has the advantages of easy to operate, light weight, save electricity and high thermal efficiency, especially suitable for the drying process of a few sample.
The purpose of Slider Kit is to gather common slideshow-like jQuery functionalities (such as news sliders, photos galleries/sliders, carousels, tabs menus)
When tracking mouse movement, you usually need to know the actual position of the mouse pointer. The event object that is passed to the handler contains some information about the mouse coordinates.
