TLD Chip Annealing Planchet with Acrylic Cover, Holds 100 TLD Chips.

The TLD Annealing Planchets are engraved with numbers 1 to 10 across the top.  The chip planchet is engraved with numbers 11, 21, 31, 41, 51, 61, 71, 81 and 91 on the side, indicating chip locations.

The specially machined holes (3/16" diameter) allow good thermal contact of the chips providing rapid cooling when placed between  the brass cooling plate set (Item 164-000), as required by the Cameron Annealing Technique.
They are furnished with two holes on one end for the Planchet Handle (Item 163-002).  An acrylic storage cover with two thumb screws provides a secure way to retain the chips in their locations after cool down.

TLD Procedure

• Bake TLD chips at 400° C for 1 hour, then quench between Brass Cooling Plates (Item 164-000)
