Efficient vacuum concentration: Martin Christ RVC series
The RVC series from Martin Christ offers a complete solution for the concentration of biological or chemical samples, based on the principle of vacuum centrifugation. This process optimises evaporation at low temperatures, protecting heat-sensitive components while significantly reducing processing times. Thanks to reduced pressure (generally between 2 and 10 mbar), the boiling point of solvents is lowered, allowing gentle, fast and reproducible concentration without the constraints of distillation or freeze-drying systems.
The RVC series includes several models tailored to specific needs: from the mini concentrator for small volumes to the maxi version for high-throughput applications. The RVC 2-18 CDplus model is designed for routine bench-top analysis. It is also available in an HCl version for acidic solvents, with materials resistant to HCl, H₂SO₄ and other aggressive agents. The intermediate RVC 2-25 CDplus model offers increased capacity while maintaining a compact footprint, ideal for laboratories with varied daily needs. The RVC 2-33 CDplus, on the other hand, is designed for large volumes and can be equipped with infrared lamps to accelerate evaporation, making the processing of high-boiling-point solvents more efficient.
The integrated CDplus control system provides a clear overview of operating parameters: rotor speed, chamber temperature, vacuum level and cycle time. The interface allows for simple and precise programming, with up to 16 sequences that can be stored depending on the model. RVC concentrators are compatible with a wide range of solvents, from the most common such asethanol and methanol to the most demanding such as DMSO or TFA.
The modular design of these systems allows them to be configured with various rotors, vacuum pumps (diaphragm or hybrid) and cold traps down to −85 °C. The choice of several rotor capacities (from Eppendorf tubes to deepwell plates) allows for great flexibility.
Thanks to their robustness, energy efficiency and compatibility with the current requirements of modern laboratories, RVC concentrators represent a sustainable solution for concentration processes.
