Warner Instruments has released the RC-30WA, a closed-bath, low-profile chamber that incorporates features for confocal imaging. The chamber is adaptable to any major microscope, upright or inverted, and features a 25-mm final viewing aperture. The bottom is beveled to permit maximum access to the bottom coverslip. For unique applications, the chamber’s bath geometry, volume and perfusion solution exchange rate can be customized by adjusting the wall height from 150 to 1500 μm with silicone rubber gaskets. It is supplied with a pair of resistive heater elements mounted to the chamber base.
