Precision Scientific 625

The Precision Scientific 625 is a mechanically ventilated laboratory oven delivering precise temperature control across a 15°C to 325°C range for research, testing, and analytical applications. Built with a 113-liter stainless-steel chamber and microprocessor PID control, this unit achieves ±0.1°C sensitivity and maintains temperature uniformity of ±0.5°C at 100°C, ±0.9°C at 200°C, and ±2.2°C at 300°C. Heat-up to 325°C requires 50 minutes; recovery time is 4 minutes at 200°C following a 30-second door opening. The all-stainless-steel interior and chemical-resistant powder-coated cabinet support extended operational life. Non-tip removable shelves enable flexible sample positioning and simplified cleaning. A built-in 12-hour mechanical timer with hold position accommodates both time-limited and continuous heating protocols.
