| The Rheodyne 7725i manual injection valve is the most advanced and widely used injection valve on the market today. Its product features include: 1.Rheodyne's continuous flow (MBB) structure design patent, in the sampling and injection switching to maintain the continuity of the flow, greatly reducing the transient pressure shock on the system interference. In this case, 2. Wide 30-degree port, easy to connect with the connector. In this case, 3. Single-point pressure adjustment, reducing the rotor seal between the friction and the stator to extend the service life. 7725i manual injection valve 4. Built-in position sensor switch provides a reproducible start signal for the chromatograph Patented MBB (Make-Before-Break) technology, effectively reducing the Load-Inject switching instantaneous pressure fluctuations. In this case, The highest temperature tolerance: 80 ℃ The maximum tolerance pressure: 48Mpa Material: 316 stainless steel, Vespel (rotor) PH range: 0-10 (if a sample or mobile phase with pH> 10 is used, a PEEK rotor can be used that can withstand pH 0-14) Stainless steel or material Working pressure 35.0MPa (5000psi) Manual or remote control operation Electronic control Stainless steel or material Working pressure 35.0MPa (5000psi) Manual or remote control operation Electronic control Main features The 7725 Series LC injection valve features very high precision and accuracy, with injection volumes ranging from 1 μL to 5 μL; normal operating pressures of 34 MPa, pressure buttons on the back of the handle, working pressure Adjustable to 48Mpa. 7725, 7725i Injector Standard 20 μL of the metering tubing is standard. 7725 Series LC Column Injection Valves In addition to the extensive functionality of the Model 7125 injection valve, Also has the following five functions: (1), take / sample conversion to keep the mobile phase (no flow channel, that is, Rheodyne's patented technology MBB) (2), behind the handle pressure button can make sealing control becomes very easy; (3), pipe connection angle range increases, facilitates the use of injection valve connection; (4) with built-in trigger (position sensing switch, only suffix for the I-type injection valve; (5), can be equipped with 2 μ l built-in ultra-trace quantitative tube and accessories. Rheodyne7725i手动进样阀是目前市场上先进和广泛使用的进样阀。其产品特性包括： 1.Rheodyne的不断流（MBB）结构设计，可以在取样和进样切换时保持流动的连续性，极大的降低了瞬时压力冲击对系统的干扰。 2.较宽的30度端口，易于与接头连接。 3.单点压力调节，减少了转子密封垫和定子间的摩擦，延长使用寿命。 7725i手动进样阀 4.内置位置传感开关为色谱仪提供了可再现的开始信号 的MBB(Make-Before-Break)技术，有效降低Load-Inject切换瞬间的压力波动。 Z高耐受温度：80℃ Z高耐受压力：48Mpa 材质：316不锈钢、Vespel(转子) pH范围：0-10 (如果使用pH＞10的样品或流动相，可选用PEEK材质的转子，可承受pH 0-14) 不锈钢或材质 工作压力35.0MPa（5000psi) 手动或摇控操作 电子控制 不锈钢或材质 工作压力35.0MPa（5000psi) 手动或摇控操作电子控制 主要特点 7725系列液相色谱进样阀具有非常高的精密度和准确性，进样量的范围可以为1微升到5微升；正常工作压力设为34Mpa，调节在手柄后面的压力按钮，工作压力可调到48Mpa。7725、7725i进样阀标准配置20微升定量管。 7725系列液相色谱柱进样阀除具有已广泛使用的7125型进样阀的各项功能外， 还具有下列五个功能： （1）、取/进样转换时流动相保持连续（流路无断流，即Rheodyne公司的MBB） （2）、手柄后面压力选钮可以使得密封控制变的十分容易; （3）、管路连接角度范围增大，方便了进样阀的连接使用； （4）、带有内装式触发器(位置传感开关,于后缀为I型进样阀; （5）、可以选配2微升内装式超微量定量管及附件. |
