Today, we are excited to share some of the amazing feedback we have received from our clients about the BQC Redox System (BRS). Our clients come from various sectors including biomedicine and agri-food, and they have been using the BRS for a wide range of purposes such as measuring antioxidant capacity, indirect oxidation, screenings, and more.

We believe that sharing these testimonials will not only showcase the versatility of the BRS but also help new labs in finding the perfect application for their work. So, whether you are a researcher in biomedicine or a professional in the agri-food industry, we hope that these real-life experiences will inspire and guide you in utilizing the BRS to its full potential.


Continue reading as we delve deeper into the specific uses and benefits of the BRS:


So far, we have used the BRS exclusively in plasma samples, from mouse, rat and human. It has been very useful to us for several reasons, the first because it does not require treatment/processing of the sample, which facilitates its use and reduces the variability of the result, second because relatively small quantities are required, and I think it must be highlighted very especially how easy the equipment is to handle and how immediate the result is, given that it works essentially like reading a glucose strip.

The new equipment is more sensitive, the measurements are even more reproducible, and it has the advantage that the data is recorded and does not require manual annotation.

Our research group, named Antioxidants, Free Radicals and Nitric Oxide in Biotechnology, Food and Agriculture at the Zaidín Experimental Station of the Spanish National Research Council (CSIC) in Granada, has been using the new BRS portable equipment to determine the electrochemical detection of total antioxidant capacity (TAC) in different plant tissues with a particular interest in pepper fruits of different varieties. Among the advantages that must be highlighted are the reproducibility of the data obtained along with the simplicity and speed of the analysis.

Our research group, “Sensory Analysis, Nutritional Assessment, and Development of New Foods,” at the University of Santiago de Compostela, has successfully employed BRS portable equipment to assess the electrochemical detection of  total antioxidant capacity (TAC) in various natural extracts (such as nettle and algae) as well as in blood and plasma samples.

The noteworthy speed of the analysis has significantly contributed to the efficiency of our investigations.

We used the old system on crab hemolymph (blood). Crabs were exposed to air and hyperoxia. The data was very clear and consistent. I will be trying it on migrating birds next week. It is an excellent tool for field work

Jules Devaux, PhD. Research Fellow at The University of Auckland


At the Marine Biodiversity, Exploitation and Conservation research unit (MARBEC, CNRS, France), we have been using the equipment for the measurement of total antioxidant capacity (TAC) in aquatic invertebrate hemolymph. We have focused on how different environmental oxygen concentrations affect marine invertebrates in terms of their redox balance. The device has proven to be reliable and provide reproducible data. We have specially appreciated the possibility of doing quick and reliable measurements in the field (which in our case is often remote places with limited access to laboratory infrastructure).

In our research group at Rey Juan Carlos University in Madrid, we have employed the BRS portable equipment to evaluate the antioxidant capacity of microalgal extracts, potentially applicable in the cosmetic, pharmaceutical, and food industries.

This equipment offers ease of use, providing immediate and highly reproducible results with minimal sample consumption. These advantages make it a valuable asset in our research activities.

Gemma Vicente, PhD. Professor of Chemical Engineering at Rey Juan Carlos University


Regarding the use of the equipment, I can tell you that it is easy to use, the values that come out are repetitive and that the gallic curve that we did was perfect. We have applied it to the analysis of the antioxidant activity of citrus fruit extracts and everything has worked correctly.

BRS not only does antioxidant capacity

It’s also designed for continuous improvement with the incorporation of new redox measurements.

Soon, we’ll be introducing accessories and consumables for these new measurements. These accessories will be part of a new line called e-drop, where we’ll group all the new parameters.
