This chamber improves the accuracy of PCR and general tissue culture procedures by greatly reducing the chance of airborne contamination during DNA sequencing. Airtight chamber features a built-in UV system rated at 254 nm to decontaminate interior surfaces. Includes fluorescent and UV germicidal lamps. Removable doors save valuable laboratory countertop space. If a corner door is opened, electrical sensors turn off the UV system. Overall chamber dimensions are 24''W x 28''H x 18''D.
