一般說明
"Dries samples using heat, vacuum, and desiccant"
Precise digital control simultaneously displays both "set" and "actual" temperatures from ambient to 230°C. A built-in thermocouple automatically maintains selected temperature. The oven features a precision machined aluminum heating block with a borosilicate glass sample-viewing port and an integrated safety guard to prevent touching hot parts. The glass drying tube is protected within the enclosed heating block and is safely contained in the event of accidental breakage. The Modular design permits the removal and storage of dried samples in sealed drying tubes. This enables rapid sample processing in succession for servicing multiple users. Order glass drying tube assembly Z222712 separately.
