KDN-16消化爐是一種廣泛應(yīng)用于實(shí)驗(yàn)室樣品預(yù)處理的設(shè)備，主要用于糧食、飼料、食品、乳制品、飲料、土肥、醫(yī)藥及其他農(nóng)副產(chǎn)品中蛋白質(zhì)含量的測(cè)定。該設(shè)備采用井式電加熱裝置，配有數(shù)顯式溫度控制裝置或電壓調(diào)節(jié)控溫裝置，使樣品在消化管內(nèi)能夠快速且均勻地受熱，從而實(shí)現(xiàn)高效的消化效果。其設(shè)計(jì)可同時(shí)對(duì)16個(gè)樣品進(jìn)行加熱消化，大大提高了實(shí)驗(yàn)效率。在消化過(guò)程中，該設(shè)備還能通過(guò)排污管和抽吸泵等裝置，將產(chǎn)生的有害氣體如SO₂與水冷卻并混合后排入下水道，有效抑制有害氣體的外逸，保障實(shí)驗(yàn)室環(huán)境的安全。KDN-16消化爐的工作電壓為交流220V，50Hz，消化時(shí)間小于1小時(shí)，適用于含氮量0.05%-90%的樣品。目前，市場(chǎng)上KDN-16消化爐的價(jià)格一般在6000元左右。上海昕瑞儀器儀表有限公司是該設(shè)備的生產(chǎn)廠家之一，其客服電話為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.
