I have a Film Hypersensitization Chamber I purchased at the RTMC Swap Meet several years ago. I’ve never gotten around to using it, so its time to find it a good home. It doesn’t have the Lumicon model# on it, by I’m reasonably sure that it is the Model 300 chamber. It is an older model than those in current Lumicon ads. See photo below. The inside chamber dimensions are 88mm in diameter and 87mm deep. The chamber is in great condition. I pulled a vacuum on it several days ago, and its holding steady. The vacuum gauge is in perfect working order. New chambers alone run $249. I’m including a thermometer, a 110V heat strip with a controller I made for it. It works great, but is not thermostatically regulated, so you’ll need to manually adjust the knob to get the appropriate temp setting. Also included is a Gast Mfg. electric vacuum pump. It’s a great match for the chamber. Does not include gas cylinder or regulator. I've reduced my asking price to $200 + shipping for both the chamber and pump. Money Orders only please. Thank you.
