ACCESSORIES • This complete line of laboratory aids will pay for themselves many times over in time saved and in accidents and frustrations eliminated. Estimate the time spent in repeatedly gathering and assembling setups involving various sizes and shapes of glassware and equipment; the time spent in improvising wedges, blocks and supports out of "anything handy." Add to that the further time saving achieved by prevention of delays caused by broken glassware so common to this process. Top your estimates off with a guess as to how many frustrations you can save per year. That's what this line which can convert the jack to a thermostatically controlled heater, hot plate, stirrer, etc. will do. Each is designed to fit SNUGLY right on top of the jack . . . and to serve independently of the jack if desired.
