C-flat TEM carbon support films

C-flat™ are a premier ultra-flat holey carbon support film perfectly suited for cryo-EM and cryo-electron tomography. C-flat™ have a perforated carbon support film with pre-defined hole size, shape and arrangement.

Unlike other holey carbon support films C-flat™ are manufactured without the use of plastics or other residues. C-flat™ are ready to use with no additional cleaning or handling steps. C-flat™ are manufactured under clean room conditions and 100% inspected before packaging. The superior quality of the holey carbon film and regular pattern of holes facilitates the use of automation in TEM.

C-flat™ are available in a variety of hole patterns, mesh sizes, mesh materials, and thick or thin carbon, so there is always a C-flat™ product optimized for your needs. Gold grids are preferred for growing cells when the toxicity of copper must be avoided. These are ideal for cryo-FIB and cryo tomography applications.

C-flat™ are available in 54 configurations:

• six different carbon patterns
• 200, 300 and 400 grid mesh
• copper and gold grid material
• two different carbon thicknesses: 20 and 40 nm

Labtech have recently lauched the Au-FLAT . A highly stable Au/Pd support film on a gold grid with the same hole pattern as 1.2/1.3 and 2/2 C-flats.

As with any carbon support film plasma treatment may be required to make the surface more hydrophilic. For this we recommend the PIE Scientific Tergeo-EM which ensures gentle, effective processing. Please see: Tergeo-EM
