Conclusion:Overall, the Rheodyne 3725i-119 preparative HPLC injector is a high-quality, reliable, and durable component that is well-suited for preparative HPLC applications. Its high-capacity loops and built-in loop switch make it a convenient and efficient choice for users who need to work with larger sample volumes. However, its high cost and large size may be limiting factors for some users. Therefore, users should carefully consider their budget and laboratory space requirements before making a decision to purchase the 3725i-119 injector.
Recommendation:If you have a budget for high-end HPLC equipment and need a reliable and efficient injector for preparative HPLC applications, the Rheodyne 3725i-119 is a good choice. Its high-capacity loops and built-in loop switch make it a convenient and efficient option for users who need to work with larger sample volumes. However, if budget or space constraints are a concern, there may be other, less expensive injectors available that may be more suitable for your needs. In such cases, it is recommended to carefully research and compare different options to find the best fit for your laboratory and budget.
It comes with all fittings and a 10 ml loop. It came with a waters prep hplc system that was automated and its own auto-sampler, so we never used this. It is a Rheodyne model 3725i and injections can be made either through the front or by use of one inlet tubes. The front of injector is a bit scuff just from moving around in drawers.
This preparative Rheodyne loop has been in our lab for many years but we never used it.
