The Kenton KZ Lab Vacuum Drying Oven designed for bio-pharmaceutical, medical, and agricultural research applications, these ovens excel in drying heat-sensitive and oxidation-prone materials. Ideal for powdered/granular samples, they significantly reduce drying time while preserving material integrity. The vacuum technology ensures gentle, efficient dehydration for critical research and production processes.
The KZ model features an LCD smart controller, while the KZ-G upgrade incorporates a touchscreen interface for enhanced operation.
Utilizes ALLHEAT™ cavity preheating and S.H-Transfer™ shelf conduction for exceptional thermal uniformity, ensuring consistent experimental conditions.
3mm thick SUS304 stainless steel cavity with five-sided structural reinforcement provides superior durability and pressure resistance.
Includes gas inlet ports for inert atmosphere applications, with KZ-G models featuring automated valve control and digital vacuum regulation for precision operation.
