Torrey Pines Scientific has launched a new line of corrosion-resistant multi-position stirring analogue hot plates and stirrers with five or nine stirring positions, making them ideal for acid digestions and working with most corrosive solutions.
The large (305 mm) square ceramic heater tops have a temperature range to 450°C. A purge port on the rear of the units is provided for purging with a positive pressure of any inert gas. Most chassis openings have been closed. This keeps corrosive vapours from gaining access to the units and protects the electronics and stirrer motors.
The five-position stirring units can stir 5 mL to 800 mL beakers, and the nine-position units can stir 9 mL to 500 mL beakers of corrosive aqueous solutions from 100 to 1500 rpm. Each stirring position is individually controlled.
The units measure 19” (432 mm) deep by 12.5” (318 mm) wide by 5.25” (134 mm) tall. They can support more than 50 pounds (22.6 kg) on the plate surface. All controls are mounted well forward of the heater surface to protect against accidental burns, and the units are designed to keep spills out of the chassis.
The units are available in 115VAC/60Hz, 220VAC/60Hz, and 230VAC/50Hz. They have a main AC on/off switch and are fused for safety. They are supplied with a user manual and detachable line cord for the country of use. All units are UL, CSA and CE or equivalent rated.
