Electron Microscopy Sciences Sodium Carbonate 500 GR
(Sodium Ethoxide)
CAS #497-19-8 Na₂CO₃ F.W. 105.99
Electron Microscopy Sciences SEM Scintillator YAP 12.0x17 mm
YAP (Yttrium Aluminum Perovskite activated by Ce3+) shares the same advantages as YAG but is more efficient in terms of light output than YAG crystals. As well, the emission spectrum peaks at about 378nm, and this corresponds closely to the maximum sensitivity of the S11 photocathode which in general is used in most scanning electron microscopes. (There would be more improvement in signal by using a YAP crystal rather than YAG in these microscopes). The decay time of YAP (40ns) is faster than YAG (80ns) so its overall performance is superior to YAG.
YAP crystals should be coated with 50nm of aluminum prior to use. Note: P-47 is usually in-stock. YAG and YAP delivery time is 6-8 weeks. Use with Zeiss SEM scanning electron microscopes.

Electron Microscopy Sciences Paraformaldehyde, Prills 1 KG
(Polyoxymethylene)
OH(CH₂O)n H F.W. 600 Average
Paraformaldehyde is the condensation product of methylene glycol, a substance not so far isolated in its pure form; it is a white solid with a formaldehyde content between 78 and 98% and is supplied either as a Prill or Granular. All forms contain more than 95.5% paraformaldehyde content. The Prill and Granular forms are small, free-flowing, dust-free beads, the most desired by EM users.

Electron Microscopy Sciences (TMS) Tetramethylsilane 100 ML
CAS #75-76-3 Si(CH₃)₄
Boiling point: 26.6-26.7°C
An organo-silicon compound, tetramethylsilane (TMS) is an ideal solvent for tissue drying for scanning electron microscopy. It is chemically inert, has as low boiling point of 26.6°C (lower than acetone, diethyl ether and 1,2-epoxy propane), and is soluble in most organic solvents but insoluble in water. These properties of TMS result in excellent tissue surface details.
