儀器簡介：

INSTEC系列冷熱臺是應(yīng)用于高分子、液晶、聚合物、纖維、半導(dǎo)體、流變等方面的觀察樣品，以及觀察各種樣品熔點、相變、形態(tài)等方面的冷熱臺；同時也可做于施加電場條件下液晶的變化，液晶增長速度等等實驗觀察。該公司生產(chǎn)的TSA02I型號冷熱臺是基于需熱期的一個熱電動冷卻器，它尤其應(yīng)用于倒置顯微鏡。它的特色包括：一個較大面積的樣品室；簡單的熱控制，改善空氣的控制；寬闊的可調(diào)視圖窗口以及可進(jìn)行定制的底座。

技術(shù)特點：

•可在-25°C-60°C度之間進(jìn)行精度溫度控制

•基于帕爾貼效應(yīng)的倒置顯微鏡加熱臺

•容納高達(dá)53mmx78mm的樣本體積

•多變的樣本底座尺寸

•預(yù)先加熱/預(yù)先冷卻了的氣體凈化

•電纜可通入樣本室

•超大面積視圖孔

•可移除以及可更換的窗口

•雙窗格窗口達(dá)到更好地?zé)峤^緣效果

•總和孔徑窗口解凍系統(tǒng)

•多變樣本室高度

•氣體凈化樣本室

•內(nèi)部蓋子以及樣本底座達(dá)到樣本溫度一致
