徠卡LN22液氮冷凍裝置

Leica LN22液氮冷凍附件專門設計用于徠卡RM2265輪轉式切片機。

無可挑剔的切片質量，甚至對于工業和原材料研究領域zui棘手的樣品也不例外 – 切片厚度設置范圍0.25到100µm之間，工作溫度低達-150°C。

室溫降到切片低溫快速方便，反之亦然。

節約空間
節約空間，易識別的LEDs顯示，靈活的儀器設置。所有設置都能備份記憶。

頂部開放式冷凍箱
頂部開放式冷凍箱在-150°C低溫下，進行無冷凝無結霜切片，甚至對于要求zui為嚴格的樣品也能實現高品質切片。

The liquid nitrogen freezing device LN22 quickly converts a rotary microtome into a cryosectioning system.

The Leica LN22 attachment consists of a cryochamber, which encloses the sectioning area, and which is refrigerated by a permanent flow of liquid nitrogen, pumped from a Dewar vessel. The automatic pumping mechanism ensures a stable low temperature environment around the frozen specimen and the knife. Separate temperature control systems maintain stable temperatures of both knife and specimen.

The desired temperature setting for knife and specimen are selected on the control unit. The control unit, which continuously monitors and regulates the selected temperature parameters and controls the liquid nitrogen pumping system.
Actual temperatures of knife, specimen and cryochamber are displayed on the control unit at all times.
The cryochamber is mounted onto the microtome base plate, thus being compley isolated from the microtome feed and drive elements.
