VEVOR Enfriador de Laboratorio 6L de Acero Inoxidable Bomba de Circulación de Enfriamiento de Laboratorio -20~100°C Pantalla LCD Enfriado por Agua de Circulación para Biotecnología, Análisis Químicos

Good product and good value. It would be a better product if the flow rate was variable.

Je suis très satisfait de ce refroidisseur circulatoire. Il est facile à installer, à régler et à entretenir. La précision de la température est excellente, il consomme peu d'énergie et sa durabilité est remarquable. Un investissement judicieux pour notre laboratoire de recherche.

Le refroidisseur circulatoire de laboratoire fonctionne parfaitement. Il maintient une température stable pendant de longues heures, ce qui est essentiel pour nos expériences. La construction est robuste, le bruit est minimal et l'utilisation est intuitive. Un équipement indispensable pour tout laboratoire sérieux.

I have been using this thermostat for about a week. I am not pushing it to the limits, just keeping it at a stable 20°C with a small amount (about 5 to 10%) of ethylene glycol added mainly as a disinfectant (not so much as an antifreeze). I rated its "quality" four stars for now because I still need to see how it performs over time. If it runs well for at least a year, I will update my rating to five stars. The price is very reasonable, and I agree with the previous reviewer on that point. However, long-term reliability is what really matters. These devices are normally expected to run continuously for years. I use six of them in parallel at different temperatures, although this is my first time buying from this manufacturer. Over the last fourteen years, I have replaced eight units, but two or at least one of the original units are still working.
