Calorimetry: Heat flow versus power compensations methods
In this note, we compare the fundamentals and operation of two calorimetry methodologies that the Simular performs: heat flow and power compensation. The mathematical calculations to calculate the energy produced or absorbed by the chemical reaction are presented. The last section directly compares both methods in terms of measurements, temperature control, accuracy, and time.
The use of a H.E.L BioXplorer in fermentations of Cupriavidus necator H16 at elevated pressure using CO2 as the sole carbon source
In this case study, the H.E.L BioXplorer was used to evaluate microbial fermentation in either autotrophic mode or heterotrophic mode.

In this study, environmental thermal instability was deliberately introduced while using the Phi-TEC I adiabatic calorimeter for exothermic reaction detection.
Investigating Zinc Oxide-Modified Mordenite as an Effective Catalyst for the Dehydrogenation of Ethanol utilizing the FlowCAT
In this study, the H.E.L FlowCAT was used for the development and optimization of a process for the production of acetaldehyde via the dehydrogenation of bioethanol. This is the first stage toward a multistep reaction, taking ethanol to higher-value chemicals.
Investigating a Sponge Metal Catalysts in a Trickle Bed Reactor for Continuous Hydrogenation Inflow
In this study, the H.E.L. FlowCAT was used to optimize the inflow of the reductive hydrogenation of an aliphatic nitro intermediate using a sponge nickel catalyst in a trickle bed reactor. Once optimal conditions were established, 1.2 kg of reagent was successfully reduced, with a yield of approximately 90% over a period of 19 hours.
Characterization of the maximum heating performance for the multi-reactor PolyBLOCK 8
In this study, we investigated the maximum temperature heating capacity of the PolyBLOCK 8 when connected to a Silicone oil heating circulator. The results show that the PolyBLOCK 8 can achieve a 90 °C difference between the oil-bath circulator and the internal temperature of both glass and high-pressure (metal) reactor vessels.
Characterization of the cooling performance for the multi-reactor PolyBLOCK 8
This study investigated the temperature cooling capabilities of the PolyBLOCK parallel reaction block with different cooling modes. The solvents used varied in boiling point, heat capacity, and viscosity. The cooling characteristics were evaluated with and without a chilling Silicone oil circulator connected to the PolyBLOCK.
Characterization of the heating performance for the multi-reactor PolyBLOCK 8
This study investigated the temperature control capabilities of the PolyBLOCK parallel reaction block with different control modes, setting a constant reactor temperature or ramping the reactor temperature. Three different solvents were investigated in four different reactors. The solvents used varied in boiling point, heat capacity, and viscosity. Connecting a silicone oil circulator showed optimum temperature control characteristics.
Investigating Hydrogenations at Different Catalyst Loadings using the ChemSCAN
In this study, a ChemSCAN is used to investigate the hydrogenation of nitrobenzene with a range of Pd/C catalyst loadings ranging from 4.0 mg to 9.3 mg. The experimental results showed that the hydrogenation reaction rate increases as the amount of catalyst in the reactor increases.
Characterization of the maximum heating capabilities of the multi-reactor PolyBLOCK 4
The maximum heating capabilities of the PolyBLOCK 4 when using a circulator were investigated in this study. The labCONSOL® control software enabled the use of different modes of heating, Heat/Cool Reactor, and Constant reactor. The results show that the PolyBLOCK can achieve a 130 °C temperature difference between the reactor temperature and the circulator temperature.
Characterization of the heating capability for the multi-reactor PolyBLOCK 4
This study investigated the heating temperature capabilities of the PolyBLOCK 4, a bench-top parallel reaction block, when connected to a circulator. Methanol and Silicone oil were the solvents heated in glass and stainless-steel reactors. The labCONSOL® control software enabled the use of different modes of heating, Heat/Cool Reactor, and Constant reactor. Connecting a circulator showed optimum temperature control characteristics.
