80mm（直径）制备色谱柱

预装柱系列

我公司拥有自主知识产权的预装柱系列产品，柱径涵盖25.4mm、41.4mm、50mm、77mm、80mm、100ml；预装柱系列产品在国际、国内市场占有非常大的市场份额。销售总量逾500套，使用客户单位超过30家。

序号	柱内径
1	ID25.4mm
2	ID 41.4mm
3	ID 50 mm
4	ID 77mm
5	ID 80 mm
6	ID 100mm

其特点：
1、采用目前国际上领先的设计方式即顶端自带手动加压装置，具有先进的轴向压缩功能；
2、还与国内军工单位合作即柱筒内壁采用精密的抛光技术和同心化技术，使柱壁的光洁度（≥▽12，即表面粗糙度Ｒａ≤0.25μm）超过了国内外同类产品并保证了柱管的同心度（0.2μm），很好的保证了产品质量的稳定性和高性能；
3、能维持足够高内压，柱床不会塌陷导致柱效急剧下降；如果柱床出现松动塌陷，无需任何工具，只需轻轻旋动顶端加压装置，便能恢复原柱内压力和柱效；
4、柱效足够高，从分析到制备很容易达到线性放大；独特的柱端分配片设计，使样品的层析过程更加均匀，峰形更加对称。
5、可以拆卸，也可以正反两个方向使用，方便自己重新装填，使用寿命大大超过一般固定法兰封口的制备色谱柱和其它制备色谱柱。
注：我们也可以根据客户要求，定做（特殊）即各种规格空制备色谱柱或根据客户要求装填如 Kromasil、HyperSil 、Fuji等各种填料，并为客户提供1年内免费再装填服务。
Special preparative chromatographic columns
Currently, our company owns Independent Intellectual Property Rights of Special preparative chromatographic columns: 25.4mm, 41.4mm, 50mm, 77mm, 80mm, and 100mm.
Characteristics:
1. Adopt currently international leading design, namely, top manual pressure device which boasts advanced axial compression function.
2. Cooperate with domestic military factories to develop the technology of precise polishing and concentricity which makes the finish (≧▽12,roughness of surface R a≦0.25μm)of column wall surpasses similar products from domestic and overseas markets and guarantees the concentricity of column (0.2μm),so stability and high performance of our products can be assured.
3. Enough high inner pressure can be maintained, column bed will not collapse which makes the performance drop all of a sudden. If the bed looses or collapses, just turn the top manual pressure device lightly so that original column pressure and performance can be recovered without any extra tools.
4. High column performance, it is easy to reach the linear amplification from analysis to preparation. Special flow distribution design for column ends makes a more balanced chromatographic process and a more symmetrical peak.
5. Columns can be taken down and also can be used in two directions, both positive and negative to felicitate refilling of particulate media. The useful life period largely overtakes those preparative chromatographic columns sealed with fixed flanges and other columns.

We can also customize different scales of preparative chromatographic columns or fill particulate media as per customers’ requirements, such as Kromasil, HyperSil, Fuji, etc. We can also provide refilling service for both domestic and imported produced columns to our customers.
