KDN-16消化炉是一种广泛应用于实验室样品预处理的设备，主要用于粮食、饲料、食品、乳制品、饮料、土肥、医药及其他农副产品中蛋白质含量的测定。该设备采用井式电加热装置，配有数显式温度控制装置或电压调节控温装置，使样品在消化管内能够快速且均匀地受热，从而实现高效的消化效果。其设计可同时对16个样品进行加热消化，大大提高了实验效率。在消化过程中，该设备还能通过排污管和抽吸泵等装置，将产生的有害气体如SO₂与水冷却并混合后排入下水道，有效抑制有害气体的外逸，保障实验室环境的安全。KDN-16消化炉的工作电压为交流220V，50Hz，消化时间小于1小时，适用于含氮量0.05%-90%的样品。目前，市场上KDN-16消化炉的价格一般在6000元左右。上海昕瑞仪器仪表有限公司是该设备的生产厂家之一，其客服电话为176 2192 3717。

The KDN-16 digestion furnace is a widely used laboratory sample pretreatment device, mainly for the determination of protein content in grains, feeds, foods, dairy products, beverages, fertilizers, medicines, and other agricultural and sideline products. This device adopts a well-type electric heating device and is equipped with a digital temperature control device or a voltage regulation temperature control device, which allows the samples in the digestion tube to be heated quickly and evenly, thereby achieving efficient digestion results. It is designed to heat and digest 16 samples simultaneously, greatly improving experimental efficiency. During the digestion process, the device can also effectively suppress the escape of harmful gases through pipes and pumps that cool and mix the gases with water before discharging them into the sewer. The KDN-16 digestion furnace operates at an AC voltage of 220V, 50Hz, with a digestion time of less than one hour and is suitable for samples with nitrogen content ranging from 0.05% to 90%. Currently, the price of the KDN-16 digestion furnace is around 6,000 yuan. One of the manufacturers of this device is Shanghai Xinrui Instrument Co., Ltd., and their customer service number is 176 2192 3717.
