Traditionally, rotary evaporators have been the go-to solution for solvent removal, offering precise temperature control and solvent recovery for a variety of applications. However, for labs handling batches of samples to dry down at a time, a high-capacity solution like [Organomation’s S-EVAP+](/products/solvent-evaporators/s-evap-plus/vacuum-evaporator?hsLang=en) may be a better fit. To help laboratories determine the most suitable evaporation system for their needs, Organomation offers an easy-to-use evaporator selection quiz. By answering a few simple questions about solvent type, solvent volume, and sample quantity, users receive a tailored recommendation for either a rotary evaporator or the S-EVAP+. ### Rotary Evaporators: A Standard in Solvent Removal Rotary evaporators, commonly known as rotovaps, are widely used in chemical, pharmaceutical, and research laboratories for [solvent evaporation under reduced pressure](https://blog.organomation.com/blog/when-is-evaporation-under-vacuum-helpful?hsLang=en). They work by gently rotating a flask in a heated water bath while applying vacuum pressure, allowing the solvent to evaporate at a lower temperature. #### When to Use a Rotary Evaporator: \- You are evaporating solvents with high boiling points. \- You are working with heat sensitive analytes. \- Your workflow involves high sample volumes up to 2 L. \- You typically only process one or a few samples at a time. While rotary evaporators are highly effective for individual sample processing, they are not always the most efficient choice for labs handling multiple samples simultaneously. This is where the S-EVAP+ comes in. ### S-EVAP+: A High-Capacity Alternative to Rotary Evaporators The S-EVAP+ from Organomation is designed for laboratories that require higher throughput than a standard rotary evaporator can offer. This [vacuum-assisted evaporation system](/products/solvent-evaporators/s-evap-plus/vacuum-evaporator?hsLang=en) enables users to efficiently process up to 10 large volume samples at once, depending on the model, making it ideal for labs that need to increase sample processing capacity without sacrificing precision. #### Key Benefits of the S-EVAP+: \- High Throughput: Available in models with up to 10 positions for increased sample processing capacity. \- Vacuum-Assisted Evaporation: Allows for gentle, efficient solvent removal across multiple samples. \- Flexibility: Works with various solvents and sample volumes, making it suitable for a wide range of applications. \- Time-Saving: Streamlines evaporation workflows by allowing multiple extractions in one system. \- Temperature Control & Safety Features: Comes equipped with a heated water bath, digital temperature controller, and the ability to recover up to 97% of starting solvent. #### When to Choose the S-EVAP+: \- You are evaporating solvents with boiling points up to 115 °C. \- You are working with heat sensitive analytes. \- Your workflow involves high sample volumes up to 1 L. \- You need to process multiple samples at one time. ### How the Quiz Helps You Decide The Evaporator Selection Quiz is designed to remove the guesswork from choosing between a rotary evaporator and the S-EVAP+. By answering three simple questions, users receive a clear recommendation based on their specific application needs: 1\. What solvent will you be evaporating? 2\. What is your starting solvent volume in mL? 3\. How many samples would you like to evaporate at a time? This quick and easy assessment ensures that you invest in the most effective evaporation system for your lab’s workflow, helping you optimize productivity and efficiency. ### Find the Best Evaporation System for Your Lab Choosing between a rotary evaporator and the S-EVAP+ doesn’t have to be a challenge. By taking the Evaporator Selection Quiz, you can determine which system best aligns with your solvent type, sample volume, and processing needs. Whether you require the precision of a rotary evaporator or the high-throughput capabilities of the S-EVAP+, Organomation has the right solution for your lab. Take the quiz today and discover the [best evaporation solution for your workflow](https://blog.organomation.com/blog/nitrogen-blowdown-evaporator-buyers-guide?hsLang=en)!  ## Get Exclusive Lab Deals Straight to Your Inbox ### Limited-time offers, special pricing, and practical lab insights in our newsletter # Contact Us If you need support from one of our technicians, please fill out our Contact Help Support form and we will respond as quickly as possible!
