Listing is for a Radleys Discovery Technologies 12 position aluminum tube block with built in gas manifold. Manifold has one inlet and 12 outlets for gas purge or vacuum. Holds 12 tubes of 1” diameter, block itself is 9” in diameter and 1.1” in thickness at the edge. Has small hole for temperature probe. Not sure what the original catalog number is and don’t see it on Radleys website so it is maybe an older product.
