LR Gold Resin

Prod # Description Unit Price Order / Quote
18183 LR Gold Resin, 500ml each $275.00
I - SDS (113KB PDF)
Resin (acrylic) only, no catalyst included. Requires Catalyst Prod. No. 18186: UV, benzoin methyl ether SDS (99KB PDF) (~365nm) (0.5% w/v); "blue light", benzyl (~460nm) (0.1% w/v); benzoyl peroxide SDS (113KB PDF) (1% w/v), cold-cure. Accurate measurements of catalyst are very important. LR Gold can be used at low temperatures (-25°C) and has proven very useful for immunogold procedures. Very low viscosity: 8cP. Applied to both LM (enzyme histochemistry) and EM (immunochemistry) techniques.

PELCO® Freezer Hats for High Pressure Freezing

cryo freezer hats

Freezer Hats are used in such Cryo instruments as:

  • Balzers
  • Leica
  • Cressington
  • RMC

Planchet designs are roughly shown below in cross section. They are available in brass only. Depths of cavity in the planchets are 0.1, 0.2 and 0.3mm. Using the two planchets, one on the other, in various combinations, permit the cavity thicknesses as illustrated below.
