Antique Solar Microbiology Inoculation loop/Scalpel Sterilizing Mushroom<br>Cultivation tool. This is the predecessor to the Bacti-cinerator, extremely rare<br>item that I'm not totally sure how to date but I'm confident it's from the first<br>half of the 20th century and likely the first quarter. Works, I plugged it in<br>and it heats up, turns red, tape on cord so I assume it was frayed. 7 5/8" wide<br>including steel rack that holds the loops/scalpels while sterilizing x 3.5" tall
