The Sirchie Cyanovac II Laboratory Fuming Chamber Outfit was designed for, but not limited to, fuming rifles and shotguns under controlled conditions. Glue-fuming under vacuum improves latent fingerprint development in every way. It is not only faster, but the fumes are distributed far more evenly. Over fuming is practically a thing of the past under vacuum. Fumes travel into crevices and around corners much more readily.
Although the size of this chamber was engineered to accommodate rifles, it can be used to glue-fume literally anything that will fit, even items that are wrinkled and creased, such as plastic garbage bags. It is constructed with heavy, 1/4" aluminum walls, the Sirchie VAC250 is engineered to easily withstand years of demanding service. It is supplied with a matched, heavy-duty, diaphragm-type vacuum pump, release valve and gauge. This is a complete system-all that is needed is the glue and the suspect item.
