          Brief Intoduction:

          The bead fusion method can eliminate the granularity, mineral and segregation effects of the samples, and can reduce the absorption and enhancement effects between the elements in the sample, and hence evidently increase the precision and accuracy of the analysis. This bead fusion method is a optimum sampling method for X ray fluorescence analysis, as well as a perfect sampling method for ICP, AA, and for indissolvable samples in wet chemical analysis.

          Fusion Machine has a certain amount of domestic applications due to the emergence of domestic manufacturers and promotion in recent years. However, the usage is still too low compared with advanced countries, primarily because of the poor quality of domestic fusion machine and high price.

          DY511 Automatic Electroheat Fusion Machine is developed by the company’s researchers based on the original fusion machines and the same preparation equipment in current international market, as the revolutionary result reaching to the new peak of electroheat fusion machine manufacturing technology. It is the first fully automatic multi-sample fusion machine with automatic filling of fusion sample. With excellent performances and reasonable price, the fusion machine can be affordable for the users who do not use fusion devices temporarily due to economic reasons. The launch of DY511 Automatic Electroheat Fusion Machine will rapidly popularize bead fusion method, thus improving the sampling quality of domestic analysis industry and bringing tremendous economic benefit for every industry or trade.


          全自動 – 整個制樣過程完全自動進行,包括熔樣室的打開、搖籃及模具支架的進出、搖籃的搖擺、將熔樣注入成型模具中等。

          高精度 – 采用鉑銠熱電偶測溫,對坩堝和模具中的熔融溫度達到準確和精確的測量和控制。

          高均質化 – 坩堝在搖籃中搖擺,保證在最短的時間內有效地攪動熔樣,使熔樣達到極高的均質化。

          光潔度 – 熔樣成型分開進行,模具的光潔度能長期保持較高(幾個月),保證了樣品的高光潔度。若坩堝同時兼作模具,則樣品在熔融過程中對鉑金坩堝的破壞使坩堝內壁會變得粗糙,一般幾天得拋光一次(還會損失白金),但由于不能保證拋光和使用的頻率,光潔度的一致性就得不到保證。

          高再現性 – 全自動、高精度、高均質化和高光潔度保證了樣品的高再現性,從而真正做到經本熔樣機同一制樣程序制備的不同樣品僅是其成分不同而沒有其他不同。

          高產量 – 最多可同時熔融4個樣品(可根據用戶要求增加到6個)。最大制樣速率達到36個樣品∕小時。

          環保節能 – 無需用水也沒有電磁場輻射危害(如高頻),無需用氣也沒有有毒產物(如燃氣式),無需大功率電源(如高頻)。采用最新的保溫材料,最小巧的熔樣室設計,使耗能降到最低。

          使用方便 – 菜單式操作,實時溫度、過程大屏幕顯示,制樣過程中無需人工監視??深A先自由設定最多達10個加熱制樣程序,其加熱過程、升溫速度、預氧化溫度、最終溫度、坩堝搖擺幅度和速度、搖擺起始溫度、冷卻時間、是否用風扇、風量大小等均可預先設定。選定程序后只需按[啟動]鍵即可,真正實現一鍵操作。

          高可靠性 – 應用單端雙螺旋硅碳棒加熱,電路、結構簡單,保證了熔樣機的高可靠性。具有最低啟動溫度報警,具有過流、過溫斷電保護并報警,并且過溫斷電保護采用與加熱制樣獨立的熱電偶測溫,與加熱控制電路一起組成三重保護,使過溫斷電保護更可靠。

          高性價比 – 價格便宜,維護維修成本極低。搖籃及模具支架采用耐高溫合金鋼制成, 保證在高溫狀態下無任何化學反應。精致而緊湊的設計,占用很小的實驗室空間。功能強大,性能卓越。是真正的高性價比產品。


          Fully automatic – The whole sample preparation process is carried out automatically, even the filling of the fusion sample in the forming mould.

          Superior accuracyThe temperature is measured by platinum-rhodium thermocouple which can accurately measure and control the fusion temperature in the crucible and forming mould.

          Homogenization – The crucible is shaking in the bracket of the crucible, which ensures the effective agitation in the shortest time and achieves superior homogenization of the fusion sample.

          Smoothness Fusing and forming are processed separately, so the forming mould smoothness can be maintained for a long term (a few months using 24 hours a day) to ensure the high sample smoothness. If the crucible is also used as the forming mould, the crucible internal wall becomes rough due to the destruction of platinum crucible by sample during fusion process which should be polished after a few days (losing platinum). However, the smoothness homogenization can’t be guaranteed without ensuring the polish and use frequency.

          Superior reproducibility Fully automatic, superior accuracy, homogenization and smoothness ensure the superior reproducibility of the sample; different samples prepared with the same preparation process by this fusion machine are uniformly the same except for the differences in composition.

          Productivity –Up to 4 samples can be fused simultaneously (maximum 6 samples if required by user).The maximum throughput is 36 samples∕hour.

          Environment friendly and energy saving No water consumption, no electromagnetic field radiation hazardous (such as high frequency), no gas, no toxic products (such as gas type), no high power supply (such as high frequency and previous electroheat). With the newest insulation material and compact fusion chamber design, the energy consumption is the lowest.
