Sample Capacity
Both the RapidVap Vertex and the TurboVap LV offer comparable sample capacity, making them suitable for moderate to high throughput laboratories. The RapidVap Vertex accommodates up to 50 samples simultaneously, while the TurboVap LV can process 48-50 samples depending on the configuration and rack used.
For laboratories processing moderate batch sizes, both systems provide sufficient capacity without requiring multiple evaporation cycles. The similar footprints of these units mean that you won't sacrifice valuable bench space regardless of which system you choose. The TurboVap LV measures 15.7" x 15.7" x 15.4" (W x D x H), while the RapidVap Vertex has a slightly larger width at 20.4" but a smaller depth at 11.2" and height at 13.0".
Heat Delivery: Dry Block vs. Water Bath
One of the most significant differences between these two systems lies in their heat delivery method, and this is where the RapidVap Vertex truly distinguishes itself.
The RapidVap Vertex Advantage: Dry Block Heating
The RapidVap Vertex utilizes a 900-watt dry aluminum block heating system that offers several compelling advantages over traditional water bath heaters:
Minimal Maintenance: Unlike water baths, the dry block requires no distilled water, no additives like Clear Bath™ solution, and eliminates the need for regular water changes and cleaning to prevent mineral buildup and algae growth. This translates to significant time savings for laboratory personnel and reduced operational costs.
No Contamination Risk: Water baths can be a potential source of cross-contamination through condensation that may drip back into samples. The dry block heating eliminates this risk entirely, ensuring sample integrity throughout the evaporation process.
No Corrosion or Rust: Water baths are susceptible to corrosion and rust over time, particularly when used with certain solvents or when mineral deposits accumulate. The aluminum dry block is not subject to these issues, extending the operational life of the instrument.
Easier Cleaning: In the event of a spill, the dry block simply wipes dry, whereas cleaning a water bath can be difficult and time-consuming.
The TurboVap LV, on the other hand, uses a 6.4-liter water bath with a temperature-controlled heating system. While water baths do provide even heat distribution, they require regular maintenance including water changes, cleaning to remove mineral deposits, and monitoring for contamination. The TurboVap LV also requires Clear Bath™ additive to maintain water clarity and prevent bacterial growth.
Temperature Range
The RapidVap Vertex provides a superior temperature range of 30°C to 100°C, giving laboratories the flexibility to work with a broader variety of solvents. This extended temperature capability is particularly valuable when evaporating solvents with higher boiling points such as heptane (98°C), toluene (111°C), or pyridine (115°C).
The TurboVap LV is limited to a temperature range from ambient to 90°C. This 10-degree limitation can result in significantly slower evaporation rates for high-boiling-point solvents, potentially adding hours to your sample preparation workflow.
For laboratories working with aqueous samples or solvents above 90°C, the RapidVap Vertex is clearly the more suitable choice, offering faster evaporation rates and greater experimental flexibility.
Nitrogen Consumption and Cost Efficiency
Nitrogen consumption is a critical factor in the operational cost of any nitrogen blowdown evaporator, particularly for high-throughput laboratories or those using nitrogen generators.
The RapidVap Vertex demonstrates excellent nitrogen efficiency. With all 50 nozzles active, the system requires 127-141.5 L/min at 20-24 psi. For partial runs using only 10 active nozzles, consumption drops dramatically to just 21-28.3 L/min at 15-24 psi.
The TurboVap LV requires approximately 1 CFM (28.3 L/min) per row of nozzles at 15 psi, which translates to roughly 160 L/min for 48-50 samples. This represents a slightly higher nitrogen consumption compared to the RapidVap Vertex.
The five individual nitrogen control valves on the RapidVap Vertex allow users to activate only the rows needed for partial runs, significantly conserving nitrogen during smaller batch processing. This flexibility can result in substantial cost savings over time, whether you're using compressed gas cylinders or generating nitrogen on-site.
Flexibility and Sample Tube Accommodation
The TurboVap LV offers an advantage in tube rack flexibility. Its Multi Rack system is designed to accommodate a range of tube sizes within a single rack, eliminating the need for multiple custom racks and saving storage space. The system can handle tubes ranging from 10-32 mm outer diameter and 32-165 mm in length with its various rack configurations.
The RapidVap Vertex, conversely, requires separate interchangeable aluminum blocks for each tube size. Seven different blocks are available, accommodating tube sizes from 2 mL microcentrifuge tubes up to 60 mL ASE vials (28 mm x 140 mm). While this requires purchasing additional blocks for different tube sizes, each custom-fitted block ensures optimal heat transfer and secure sample positioning.
For laboratories that work with a wide variety of tube sizes simultaneously, the TurboVap LV's flexible rack system may be more convenient. However, laboratories that typically work with one or two standard tube sizes will find the RapidVap Vertex's dedicated block system provides excellent performance and stability.
Price and Value
For laboratories with budget constraints—including academic labs, startups, and facilities operating on grant funding—the RapidVap Vertex provides excellent value.
When considering total cost of ownership, the RapidVap Vertex's minimal maintenance requirements and slightly lower nitrogen consumption can result in significant operational savings over the instrument's lifetime.
The simplicity of the RapidVap Vertex design—particularly the maintenance-free dry block system—helps keep both initial costs and ongoing maintenance expenses lower compared to water bath systems.
Digital Features and Programmability
Both systems feature modern touchscreen digital controls that enhance ease of use and reproducibility.
The RapidVap Vertex includes an LCD touchscreen with comprehensive programming capabilities. Users can program temperature from 30° to 100°C in 1°C increments and set timers from 1 to 999 minutes. The system's memory stores up to 10 different programs, allowing laboratories to save and recall specific protocols for different sample types, ensuring consistency across runs.
The RapidVap Vertex also includes a temperature sensor probe that can monitor either the block temperature or be inserted directly into a sample to monitor actual sample temperature. This dual-monitoring capability provides flexibility in temperature control strategies.
The TurboVap LV features a 7-inch touchscreen interface with advanced programming options. The system allows users to save methods and offers multiple evaporation modes including Manual, Time, and Method modes with multi-step gradients. The gradient programming feature allows gas flow to increase gradually as evaporation progresses, potentially preventing sample splashing while accelerating the final stages of evaporation.
For most applications where time-based evaporation is sufficient, the RapidVap Vertex's programmability provides excellent protocol consistency and ease of use.
Sample Positioning and Surface Area Optimization
The RapidVap Vertex features a unique angled sample block design that increases the surface area of samples during evaporation. By tilting the samples at an angle, the evaporation interface is enlarged, resulting in faster evaporation rates and improved analyte recovery. This gentle vortex motion within the sample, combined with nitrogen blowdown, creates an efficient evaporation process.
The TurboVap LV utilizes patented gas vortex shearing technology. The system directs nitrogen through fixed-position nozzles to create a helical flow pattern within each tube.
Both systems deliver excellent evaporation performance, with the choice depending on your specific application requirements and preferences.
Sample Visibility
If maintaining visual contact with your samples throughout the evaporation process is important, the TurboVap LV offers a notable advantage. The TurboVap LV's water bath features a glass enclosure that allows samples to remain visible from the sides as the solvent level decreases. This visibility can be valuable when drying to a specific endpoint or when monitoring the progress of complete dryness, particularly for critical samples.
The RapidVap Vertex features a glass lid that provides top-down visibility of samples. While you can view samples from above and monitor their progress, side visibility is not available due to the aluminum block design. However, for most applications where timer-based or temperature-monitored evaporation is used, this level of visibility is entirely adequate.
Placement and Ventilation
Both units include a built-in exhaust fan with blower, allowing for the systems to be operated outside of the fume hood, as long as the tubing is connected to a proper ventilation system.
Chemical Resistance and Durability
Both systems offer acid-resistant options for laboratories working with corrosive chemicals.
The RapidVap Vertex features a PTFE-coated aluminum chamber and sample block, providing broad chemical compatibility. All mechanical components are isolated from chemical fumes and vapors, protecting the instrument from chemical attack and extending its operational life. This design ensures that the RapidVap Vertex can handle strong acids, bases, and organic solvents without degradation.
The TurboVap LV is available in an acid-resistant PTFE-coated version (model 416200) for work with corrosive solutions. The PTFE coating on the manifold nozzles prevents corrosion when working with acidic samples.
Both systems demonstrate excellent chemical resistance when properly specified for your application.
EPA Method Compliance
Both systems have demonstrated compliance with EPA analytical methods commonly used in environmental testing laboratories.
Evaporation Rates and Efficiency
Both systems deliver excellent evaporation performance, though their technologies differ.
The RapidVap Vertex provides published evaporation rate data demonstrating efficient sample processing. For example, evaporating 2 mL of acetonitrile at 80°C with 16 psi nitrogen pressure takes less than 8 minutes, while 2 mL of methanol at 80°C with 24 psi completes in less than 6 minutes. The combination of angled samples, dry block heat up to 100°C, and nitrogen blowdown creates fast, reliable evaporation.
The TurboVap LV's patented vortex shearing technology is designed for high-speed evaporation. The manufacturer claims the system is 10 times faster than centrifugal evaporators, 3 times faster than hot blocks.
Both systems provide efficient sample processing that significantly accelerates laboratory workflows compared to traditional methods.
