Solvent evaporation/concentration


Solvent evaporation/concentration is a critical step in the sample preparation process used by the clinical, food, environmental, pharmaceutical, chemical, and biotechnology industries. Because so many different types of samples and solvents are used for evaporation or concentration, no single technique can provide a universal solution. Over the years, many evaporation and concentration systems have been developed to address the range of applications and various market segments. These systems are based on nitrogen gas, vacuum pumps, cold traps, and heating technologies. There have been many new developments in dry heating baths as well as direct-to-vial endpoint delivery that are ready for deployment to an analytical instrument.

Laboratories today benefit from more consistent, reproducible results thanks to new concentration technologies that improve sample integrity and reduce the costly errors and intensive labor associated with the final manual transfer step. An understanding of the most up-to-date evaporation and concentration processes, their application at a practical level, and use of the latest equipment permits optimization of protocols for improved and more rapid sample concentration.



Automated Direct-to-Vial Concentration and Evaporation

The SuperVap system is an automated, standalone, direct-to-vial concentrator that replaces older techniques such as KD, nitrogen blow down and water baths. By automating what were once manual evaporation and concentration processes, the SuperVap concentration system accelerates your sample throughput, lowers labor costs, and improves the consistency of your results by eliminating the variability inherent in manual sample prep procedures.

The SuperVap concentrator sets new a standard for consistency, speed, and reliability of results for an automated sample evaporation and concentration system. It is ideal for the analysis of pesticides, herbicides, Persistent Organic Pollutants (POPs), PCBs, PAHs, pharmaceutical byproducts, and personal care byproducts as well as many other applications. The programmable SuperVap concentrator is a dry, waterless concentrator that can preheat as well as ramp up to final temperature. It automatically senses when the extract is being delivered to each vessel, starts the blow down and then shuts off the nitrogen when final volume is achieved. The concentrated samples are then automatically transferred directly to a vial, eliminating the errors that occur during manual transfer.

The SuperVap concentration system uses a touch screen display for programming, storing, and running methods. Real-time plotting of temperature readings are displayed throughout the process. Simply touch a point on the plot and instantly see the temperature of that point.

Reduces Errors
The SuperVap system performs the entire evaporation and concentration process, automatically, delivering consistent, reproducibly high recoveries for all analytes. Unattended operation of the sample prep process saves time, reduces labor costs, glassware and solvents.

High Recovery of All Analytes
The SuperVap system provides direct-to-vial concentration with automatic endpoint detection and Nitrogen shut off for each vessel

Uses No Water
Uses a robust waterless, dry bath with no electronics submerged in water. It easily and inexpensively captures solvents.

Concentrates up to 6 Samples
Sample Sizes up to 220 mL. 

Compact Size

Minimizes Contamination
An integrated HEPA/Carbon filter eliminates outside contamination.

Inexpensive Glassware
Economically priced vessels in 500 µL, 1 mL and direct-to-vial.

Fully Automated
Automatic endpoint detection, nitrogen shutoff, and alarm for each vessel. Programmable heat ramp and nitrogen settings for precise control of the concentration and evaporation process.

Every method and run is documented and stored on the SuperVap system for easy retrieval for electronic documentation. A temperature log for each run is also saved and may be downloaded to a PC via a USB port.

Stand Alone or Integrated
The SuperVap concentrator can be easily integrated into existing FMS sample preparation systems. Integration allows for PC-based control and automatic solvent exchange.

PowerPrep Multi-Column Sample Cleanup System 
The PowerPrep Multi-Column Sample Cleanup System is the only automated sample processing system of its kind available today. It is an automated liquid chromatography system that performs simultaneous sample processing unattended. The total sample preparation process; ­sample loading, washing, elution, fraction collection, and concentration is performed automatically.
Pressurized Liquid Extraction or PLE system 
The PLE® system is a high-speed pressurized liquid extraction system designed to perform sample extraction of multiple samples simultaneously. The PLE system delivers high recoveries and excellent precision for all analytes in minutes instead of hours.
Total Rapid Prep System 
The Total Rapid Prep system combines three sample prep processes into one economical package. It performs the extraction, sample cleanup and concentration steps for six samples simultaneously in less than a few hours, while delivering the highest recoveries and best results for all target analytes.
TurboTrace Sequential Parallel Automated Solid Phase Extraction System 
The TurboTrace® Sequential Parallel Solid Phase Extraction System One-Step Extraction and Concentration System is designed to streamline your workflow and increase productivity by automating the manual steps in your sample preparation process. The PowerPrep SPE system replaces older manual Liquid-Liquid Extraction techniques and outdated semi-automated instruments and automates existing manual SPE methods.
