Catalyst Screening Platforms | Manual Systems

Our complete range of multi-sample high throughput catalyst screening vessels has been designed to provide a simple easy-to-use tool for high-pressure reaction screening. They can be used directly with stirring hotplates or oil baths.

CAT 7, 18, and 24: The CAT 7, 18, and 24 are manual catalyst screening reactors, supporting 7, 18, and 24 vials, respectively.

DigiCAT 96: The DigiCAT 96 is an automated catalyst screening platform that supports a standard 96-well Zinsser block for high throughput screening early on in catalyst development.

PolyCAT 4 and PolyCAT 8: The PolyCAT 4 and 8 are bench-top, automated parallel catalyst screening platform, designed for the rapid screening of high-pressure reactions and catalysts.

CAT 7, CAT 18 & CAT 24

CAT Reactors:
7, 18 or 24 Vial, Manual Catalysis Screening Reactor

The CAT 7, 18, and 24 are manual catalyst screening reactors, supporting 7, 18, and 24 vials, respectively. Each unit is a single vessel into which sample vials are placed, with the CAT 7 supporting 10 ml vials, the CAT 18, 2 ml vials, and the CAT 24 holding 4 ml vials. The sample vials within the CAT reactor blocks are stirred and heated on a hot plate under manual operation. They are held at the same pressure and temperature, enabling replicates to be performed within the same experiment, thereby accelerating development time.

Features and Options:

Vessel Types and Volumes

CAT 7: Designed to be used with 7 standard 10 ml vials
CAT 18: Designed to be used with 18 standard 2 ml vials
CAT 24: This allows the use of 24 open-top vials to be used at high pressure and temperature. The typical test volume is around 1 ml

Temperature

All samples within each vessel are maintained at the same temperature and pressure, up to 100 bar / 250 °C.
Reactor block temperature can be monitored directly via a thermocouple probe.

Manual High-Pressure Reactor

Valves and pressure gauge provided to manually purge (for example, inert) and further pressurize with reacting gas (for example, hydrogenation), up to 100 bar.

Stirring Available

Magnetic stirring in each reaction vial

Sample Integrity

To prevent carryover, the vials can be fitted with septa.
For larger vessels used in the CAT 24, the lids are fitted with cold fingers, which are chilled by an external coolant (eg tap water), to mitigate the crossover of vapors between reaction vessels.

DigiCAT 96

DigiCAT 96:
A 96 Well Plate Automated Catalysis Screening Platform

The DigiCAT 96 is an automated catalyst screening platform that supports a standard 96-well Zinsser block for high throughput screening early on in catalyst development. The system maintains the same temperature and pressure across each sample, enabling the rapid collection of statistically representative data on the performance of a candidate catalyst. The 1 ml vials are also compatible with HPLC, allowing the reaction mixes to be directly analyzed by compatible analytical techniques.

Features and Options:

Vessel Types and Volumes

96 well Zinsser block, for 96 simultaneous reactions in 1 ml vials.

Temperature

All samples are maintained at the same temperature, between ambient and 200 °C.

High-Pressure Reactor

Automated gas purge (for example, inert) and further pressurize with reacting gas (for example, hydrogenation), up to 100 bar

Stirring Available

Magnetic stirring for each reaction vial

Intelligent Software Control and Analysis

Control software enables regular data logging, multi-step recipes, parameter control and feedback loops.

Safety Features

Include automatic user-configurable shutdown procedures if a safety condition is exceeded to ensure user safety.
Automatic hardware and software fail-safes are installed on every system

PolyCAT 4

PolyCAT 4:
Bench-top, 4-reactor, automated parallel catalyst screening platform

The PolyCAT 4 is a bench-top, automated parallel catalyst screening platform, designed for the rapid screening of high-pressure reactions and catalysts. The 4 reactor variant, supports reactors ranging from 16ml to 500ml. As with the fully automated ChemSCAN, each stirred reactor is independently controlled and monitored, allowing screening tests to be carried out concurrently and accelerating development time.

Features and Options:

Vessel Types and Volumes

The system supports four reactors in parallel operation. Reactor volumes range from 16ml to 500ml, available in SS316 Stainless Steel or Hastelloy.

Temperature Control

Ambient to 250 ⁰C.
Options to decrease the range down to -40 ⁰C (circulator dependent)
A separate mantle around each reactor allows the temperature to be controlled individually, with a range/difference of over 100 °C between the reactors.

High Pressure and Vacuum Systems

Each reactor can be independently pressurized up to 200 bar.
Pressure gauges, or optional transducers, enable reaction pressure monitoring.

Control Options

Reactors can be set to different start pressures, allowing the controlled stirring to initiate the reaction.
Availability of manual purge and gas feed for each reactor.

Stirring Available

Indirect agitation with magnetic stirrer bar as standard.
Suspended mechanical agitation for efficient mixing on small-scale and non-viscous samples.
Optional Overhead direct agitation for larger vessels.

Intelligent Software Control and Analysis

Control software enables regular data logging, multi-step recipes, parameter control, and feedback loops.
Experiments can be designed to:
- Run all reactions at the same temperature and pressure -while varying the catalyst or reagents.
- Keep catalyst loads identical but vary the initial pressure.
- Run individual reactors with different loads, pressure, and temperatures

Safety Features

Include automatic user-configurable reaction detection and shutdown procedures, to ensure user safety.
Compact manifold for easy manual purge and pressurization.
Automatic hardware and software fail-safes are installed on every system

PolyCAT 8

PolyCAT 8:
Bench-top, 8-reactor, automated parallel catalyst screening platform

The PolyCAT 8 is a bench-top, automated parallel catalyst screening platform, designed for the rapid screening of high-pressure reactions and catalysts.
