Bruker Multimode 8

The Bruker MultiMode® 8 (MM8) is an advanced atomic force microscope (AFM) and Scanning Tunnelling Microscope (STM). Its PeakForce Tapping technology enables exceedingly low tip-sample force interactions compared to tapping mode, making it particularly useful for delicate samples by allowing the user to control the maximal force imparted to the sample. The MM8 also features the Bruker ScanAsyst® software, automating the optimisation of scanning parameters for users to obtain quality images.
 
The MM8 is equipped with a magnifying camera to view the sample surface to easily locate regions of interest for imaging. The stage is temperature controlled and samples can be imaged in air or immersed in fluid. The versatility of the MM8 allows for Scanning Tunnelling Microscopy (STM) capabilities, providing a high resolution image of the surface and sample interactions.
 
PeakForce QNM (Quantitative Nanomechanical Mapping) is also supported on the MM8 allowing for the rapid acquisition of multiple sample properties simultaneously; including topology, modulus, adhesion and deformation; and the superimposition of these properties in a single image. Moreover, the MM8 is capable of mapping the conductivity of a sample with a specialised tip is supported using the PeakForce TUNA™ feature. The MM8 can also generate a map of the electrochemical potential of a sample in fluid. This gives the MM8 the versatility to study a wide range of non-biological materials, from soft polymers and liposomes to silicon and titanium surfaces.
