We're looking for a quote for three different cryogenic vacuum chambers, each with specific dimensions and features. Our company is based in Melbourne, and we need details on the chambers that include various ports for cryocoolers, observation windows, and other functionalities. Please provide pricing for a small cylindrical chamber, a cube with a hinged door (in two sizes), and a large cylindrical chamber. We're particularly interested in the configurations and materials used. A prompt response would be appreciated so we can discuss further details.
