玻璃底皿與培養(yǎng)皿
采用玻璃底皿,工作距離短,熒光、共焦、高N.A.物鏡
以及圖像分析實驗。
中間有縮小的光學窗口(小于15或11毫米)的加熱元件將提供更好的
您的樣品溫度穩(wěn)定,非常適合與玻璃底盤和長距離工作
目標。但是,如果使用浸入式物鏡,這個小窗口將限制進入
整個底面的大型浸沒物鏡。在這種情況下,加熱元件為35mm
應使用間隙/窗TC-E35。使用物鏡仍能提供溫度穩(wěn)定性
加熱器。
與玻璃底皿相比,玻璃底皿具有良好的熱接觸性,因為玻璃底為fla,
標準的塑料培養(yǎng)皿通常在底部邊緣有一個突出的邊緣。這個
邊緣把盤子舉過受熱面。金屬墊片/墊圈可用于消除這種氣隙,
然而。這將減少浸入式光學元件到盤底部的通道,因此TC-E35x15/11可以
僅用于遠程目標。如果使用浸入式光學元件和大型物鏡,35毫米加熱
元件TC-E35應與目標加熱器結合使用。請注意,一些玻璃底
碟子,例如馬特克碟子,是由標準的康寧(或獵鷹碟子)制成的。
由于不同品牌的菜有不同的外徑,有時大于38毫米,我們做
減少插入件以提供更好的fi和與加熱元件內(nèi)部切口的熱接觸,
38毫米。我們還制作了一個50毫米的插件,將培養(yǎng)箱和更大的加熱元件內(nèi)的培養(yǎng)皿居中,
里面有50毫米的切口。

Glass Bottom Dishes vs. Petri Dishes
Glass bottom dishes are used with short working distance, high N.A. objective in fluorescence, confocal
and image analysis experiments.
The heating elements with reduced optical window in the middle (down to 15 or 11mm) will provide better
temperature stability for your sample, and are perfect for use with glass bottom dishes and long-working-distance
objectives. If immersion objectives are used, however, this small window will limit access
of the large immersion objective to the whole bottom surface. In this case a heating element with 35mm
clearance/window TC-E35 should be used. Temperature stability still can be provided by using an objective
heater.
In contrasts to glass bottom dishes, which provide good thermal contact because of fla glass bottom,
standard plastic Petri dishes very often have a protruding rim alone the bottom edges of the dish. This
rim elevates the dish above heating surface. Metal shims/washes can be used to eliminate this air gap,
however. This will reduce access for the immersion optics to the bottom of the dish, so TC-E35x15/11 can
be used with long-distance objectives only. If using immersion optics and large objectives, 35mm heating
element TC-E35 should be used, combined with an objective heater. Please note, that some glass bottom
dishes, Mattek dishes for example, are fabricated from standard Corning (or Falcon dishes).
Since different brands of dishes have different outside diameter, sometimes larger than 38mm, we make
reducing inserts to provide better fi and thermal contact to the inside cutout of the heating elements,
which is 38mm. We also make a 50mm insert to center the dishes inside incubators and larger heating elements,
which have 50mm inside cutout.
