1.采用一套裝柱機(jī)，可以填裝多根色譜柱
2.裝柱時(shí)間短，無(wú)需二次拆裝，避免傳統(tǒng)色譜柱在拆裝時(shí)柱床反彈而影響柱效
3.活塞頭與柱床始終接觸并保持裝柱壓力，避免了傳統(tǒng)色譜柱長(zhǎng)時(shí)間使用后柱床塌陷的問題，延長(zhǎng)使用壽命。
4.特殊設(shè)計(jì)的柱底密封結(jié)構(gòu)，保證良好的密封
5.特殊設(shè)計(jì)加工的強(qiáng)制分配及收集系統(tǒng)，可以保證色譜柱高性能
6.內(nèi)壁表面粗糙度 Ra ≤0.2μm
7.內(nèi)壁采用珩磨，拋光,加工工藝
我公司生產(chǎn)的彈簧預(yù)緊色譜柱（SAC）相比其它廠家產(chǎn)品的優(yōu)勢(shì)在于：
1）采用氣缸替代氣動(dòng)液壓放大泵。其優(yōu)勢(shì)所有管路均為氣壓管路，除了色譜柱管內(nèi)部壓力，其它壓力均不超過(guò)8bar，安全性更好；其次，只使用壓縮空氣作為動(dòng)力來(lái)源，操作環(huán)境更清潔。
2）管路布局更為簡(jiǎn)潔。省去了氣壓轉(zhuǎn)液壓的所有零部件，一致性更好，操作空間更大更方便。
3）特殊設(shè)計(jì)的柱底密封結(jié)構(gòu)，只用手?jǐn)Q緊即可實(shí)現(xiàn)密封。
4）特殊設(shè)計(jì)加工的分配方式，可以保證色譜柱的高柱效。
5）操作時(shí)間短，節(jié)省試劑。
1. With a set of column machines, multiple columns can be filled
2. The column loading time is short, and there is no need for secondary disassembly and assembly, which avoids the rebound of the column bed during the disassembly and assembly of the traditional chromatographic column and affects the column efficiency
3. The piston head is always in contact with the column bed and maintains the column loading pressure, which avoids the problem of column bed collapse after long-term use of the traditional chromatography column and prolongs the service life.
4. Specially designed column bottom sealing structure to ensure good sealing
5. Specially designed and processed forced distribution and collection system can ensure the high performance of the column
6. Inner wall surface roughness Ra ≤0.2μm
7. The inner wall adopts honing, polishing and processing technology
The advantages of our spring preloaded column (SAC) compared with other manufacturers' products are:
1) Adopt pneumatic cylinder instead of pneumatic hydraulic amplification pump. Its advantages are that all the pipelines are pneumatic lines, except for the internal pressure of the chromatography column tube, the other pressures are not more than 8 bar, which is safer, and secondly, only compressed air is used as a power source, and the operating environment is cleaner.
2) The pipeline layout is more concise. All parts of pneumatic to hydraulic pressure are omitted, and the consistency is better, and the operation space is larger and more convenient.
3) Specially designed column bottom sealing structure, sealing can be achieved by only hand tightening.
4) The distribution method of specially designed processing can ensure the high column efficiency of the column.
5) Short operation time and saving reagents.
