美國VICI通用色譜 兩通 三通 四通 等配件用于色譜分析的Valco配件通常是壓緊配件， 隨著(zhù)螺母的擰緊，壓環(huán)被壓緊到管路上。為GC、HPLC和UHPLC中的高壓應用提供了理想的穩定性和可靠性。
美國VICI通用色譜 兩通 三通 四通 等配件
1、Microvolume Connectors--微體積連接器
當傳統的機械加工設備無(wú)法在典型的接頭、三通和四通上鉆納米孔時(shí)，這種混合兩件式設計是的。目前的加工技術(shù)已經(jīng)進(jìn)步到允許在標準裝配體中加工納米孔通道，至少對大多數材料來(lái)說(shuō)是這樣。與初的兩件式設計相比，這些配件的制造成本更低，并提供了其他優(yōu)勢。由于這些原因，我們正在將大多數材料轉換為一體式設計。除了少數例外，以前在微體積兩件式設計中可用的內容現在將在新的一體式設計中可用，在大多數情況下價(jià)格更低！
請注意，原來(lái)的微容積配件在配件中心有一個(gè)8-32螺紋安裝孔。在新的一體式版本中，此安裝孔是可選的。
2、Unions--直通/兩通
2.1 Internal unions--內螺紋直通
標準型
隔板型(可通過(guò)儀表面板或支架安裝。裝配體被咬邊，以便在擰緊安裝螺母時(shí)咬入面板，從而無(wú)需使用鎖緊墊圈。)
