Technical specifications:
Various microscopy supplies, such as TEM grids, silver paste, stage micrometer and different types of tweezers are to be quoted that meets or exceeds the following technical specifications (partial quotes can be accepted):
A) TEM grids:
A1) Amorphous carbon covered TEM grids:
Amorphous carbon film (typical thickness 5-6nm) covered Cu grids
Grid: square, 200 mesh
Outer diameter: 3.05 mm
Thickness: standard
Quantity: 100 pieces
A2) Lacey carbon TEM grids:
Cu grid coated with a carbon film of a broken pattern consisting of irregularly sized and shaped mesh-like openings.
Grid: square, 200 mesh
Outer diameter: 3.05 mm
Thickness: standard
Quantity: 100 pieces
B) Conductive silver paste:
Fast drying at room temperature. (Dry to the touch in a few minutes.)
Acrylic resin based composition.
Thinning with acetone is a benefit.
At least 60% silver content.
Quantity: 1 bottle/25gramm
C) Stage micrometer:
Precise for routine calibration of light microscopes, which preferably works both for transmitted and reflected light.
General purpose design. (tracebility and certificate is not a must)
Horizontal scale (scale is along the longer side) 5mm in 0.05mm divisions.
Size: like a microscope slide, i.e. approx. 75 x 24 x 1mm
Robust construction is considered as a benefit.
Quantity: 1 piece
