美国VICI通用色谱 两通 三通 四通 等配件用于色谱分析的Valco配件通常是压紧配件， 随着螺母的拧紧，压环被压紧到管路上。为GC、HPLC和UHPLC中的高压应用提供了理想的稳定性和可靠性。
美国VICI通用色谱 两通 三通 四通 等配件
1、Microvolume Connectors--微体积连接器
当传统的机械加工设备无法在典型的接头、三通和四通上钻纳米孔时，这种混合两件式设计是的。目前的加工技术已经进步到允许在标准装配体中加工纳米孔通道，至少对大多数材料来说是这样。与初的两件式设计相比，这些配件的制造成本更低，并提供了其他优势。由于这些原因，我们正在将大多数材料转换为一体式设计。除了少数例外，以前在微体积两件式设计中可用的内容现在将在新的一体式设计中可用，在大多数情况下价格更低！
请注意，原来的微容积配件在配件中心有一个8-32螺纹安装孔。在新的一体式版本中，此安装孔是可选的。
2、Unions--直通/两通
2.1 Internal unions--内螺纹直通
标准型
隔板型(可通过仪表面板或支架安装。装配体被咬边，以便在拧紧安装螺母时咬入面板，从而无需使用锁紧垫圈。)
2.2 External unions--外螺纹直通/两通
Standard External Unions --1/8" Tubing OD
2.3 Unions - External/Internal 直通 外螺纹/内螺纹
