EM-Tec FIB lift-out grids
EM-Tec FIB lift-out grids provide a secure way to attach TEM lamellae to the grid posts following lift-out. Available in multiple post configurations, with a shape optimized for easy accessibility during lift-out, EM-Tec FIB lift-out grids are compatible with all standard 3mm TEM grid holders.
Key features and advantages of EM-Tec lift-out grids
- Multiple post configurations
- Easy identification of post and side
- Shape optimised for easy accessibility during lift-out
- Compatible with all standard 3mm TEM grid holders
- Available in three types: copper, molybdenum and smooth molybdenum
EM-Tec FIB lift-out grids have a number etched into the left side to distinguish front and back. This number corresponds with the number of posts on the grid. Unique symbols beneath each post enable easy post identification.
By using our combined FIB lift-out grid and specimen holders the specimen and lift-out grid can be positioned close together for efficient FIB lift-out operations. The specimen stubs and FIB grid holder can be rotated and height adjusted for optimum FIB lift-out operations.
EM-Tec copper FIB lift-out grids are available with either 2, 3, 4 or 5 posts. The thickness of each grid is 30-40µm, which makes them more rigid than standard TEM grids. EM-Tec FIB lift-out grids undergo a unique cleaning process to reduce contamination, which results in improved mounting and imaging of TEM lamellae. Copper lift-out grids have a set-back ridge at the edge of the front side and smooth side walls.
EM-Tec molybdenum FIB lift-out grids are sturdier than copper grids and used where copper would interfere with the investigation of TEM lamellae or for challenging applications requiring high temperatures or harsh treatments. The thickness of standard Mo FIB lift-out grids is 45-55µm. Available with 2, 3 and 4 posts. Due to the material and the manufacturing process, the side walls of the Mo FIB lift-out grids are rougher than the those of the Cu FIB lift-out grids. Use of FIB is therefore needed to make the sidewalls smoother.
A common problem with Mo FIB lift-out grids is the roughness of the side wall. It takes valuable FIB time to smooth out the sidewall of the standard molybdenum FIB lift-out grids to enable secure mounting of the TEM lamellas. To solve this common problem and to reduce cost at the FIB, we have developed the smooth side wall Mo EM-Tec FIB lift-out grids. They are made with a unique manufacturing process with the result that smoothing with the FIB is virtually eliminated or reduced to a faction of the time previously needed. These unique Mo EM-Tec FIB lift-out grids are available with two, three or four posts and a thickness of 45-55µm. Packaging size is vial/25
