Characterization Study

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.

Characterization Study

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 Study

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.

Case Study

FlowCAT experimental set-upInvestigating 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.

Case Study

“By using the iso-BTC - isothermal calorimeter, coupled with a charge/discharge unit, which is specifically designed for the testing of cells and battery packs. We could characterize “Battery A” over a wide range of operational conditions. From this, we can observe certain characteristics and gain further understanding of the battery’s features.How to use an isothermal calorimeter to characterize a gel battery
