Characterization Study
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.

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.

Application Note
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 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 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.

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.
