Used GATAN 691 #9372822 for sale

GATAN 691 is a unique broad-range ion beam milling equipment ideal for specimen preparation prior to electron microscopy. The system utilizes a unique application of low-energy ion beams that can precisely remove, sculpt, and pattern delicate sample surfaces. The process is non-ablative, meaning that the sample is not destroyed or melted, which allows for higher quality imaging results. The unit features an adjustable ion beam that can targeted a wide range of sample surfaces as well as allow for manipulation of certain small features. The Ion beam is generated by a magnetically confined, low-energy ion bombardment source which is controllable using a computer interface. The ion beam can be focused and used to cut thin sections of samples without running the risk of destroying them. By using this unique method, the machine enables a variety of users, from advanced electron microscopists, to amateur sample preparation enthusiasts, to gain access to a powerful milling tool. A computer-controlled ion gun delivers ions that are accelerated to a low-energy range and directed through the beam electrode towards the sample. Once the samples are struck by the ion beam, a directed current is created and the atoms around them get swept away to enable further clean manoeuvrability. This manoeuvrability and precision allows extremely delicate features on the sample to become accessible. The user-friendly interface enables precise control over the ion beam. It also allows for the maximum power of the beam to be adjusted, ensuring that the sample is not over-bombarded. The asset also features a stage for the sample to be mounted during the process of ion milling. The sample can be adjusted to any angle and the stage can be moved around to change the angle of the samples. The model has two additional chambers, one for annealing samples and one for depositing additional material after milling is complete. 691 is one of the most powerful ion milling systems on the market and provides the highest levels of precision for specimen preparation. With its powerful processing capabilities and the ability to perform many complex operations, it is the perfect tool for samples that require a meticulous touch for successful sample preparation. Not only is it an ideal tool for electron microscopy applications, but it is also an invaluable tool for a wide range of other applications.
