Package Solution for Flow Chemistry

 

The UI-32 Intelligent Pump and BP-11 Auto Backpressure Regulator seamlessly combine to meet the pumping and system regulation needs of flow chemistry.

This package delivers both the pumping (forward) solution as well as the regulation requirement (back) needed for flow processes. Full control of system conditions is delivered from two points along the system—in front of  and after the flow reactor. This allows for optimal conditions for system operation including temperature and pressure.

 
 

Conducting reactions at high temperature and pressure is often a requirement for efficient process, however, components boiling is a significant issue. The UI-32 Intelligent Pump and BP-11 Auto Backpressure Regulator can easily achieve high temperatures with a highly sensitive pressure control system that is fully automated for faster reaction rates and enhanced control over any volatile or gaseous components.

 
Consistent Pressure Control
 

Simple and Easy Installation

The UI-32 Intelligent Pump and BP-11 Auto Backpressure Regulator are very simple to set up. Minimal tubing work is necessary, with each component having complete internal tubing. Signal connections are established via an industry-standard RS232C cable.

 
 
 

Convenient Operation

Parameters can be set using a straightforward user interface. Simply input the parameters for the pump and regulator to begin your process.

 
 
 

UI-32 Intelligent Pump

 

The UI-32 Intelligent Pump is a compact, high-precision pump designed for flow chemistry. Featuring a dual plunger system with two independently controlled linear drives, it ensures a stable, ultra-low pulsation flow. Real-time backpressure management is facilitated by a built-in pressure sensor connected to the BP-11 Auto Backpressure Regulator.

Suitable for various developmental scale flow chemistry applications, it operates in two flow ranges: low (0.001–9.999 mL/min) and medium (0.01–99.99 mL/min). The pump supports a wide range of liquid phases with materials like stainless steel, polyether ether ketone (PEEK), and polychlorotrifluoroethylene (PCTFE).

 
 

Compact Size

Measuring just 144 x 79 x 240 mm (5.67 x 3.11 x 9.45"), the UI-22 is incredibly compact, up to a third of the size of some competitors.

 

High-Performance Linear Drives

The UI-32's plunger pumps are powered by independently controlled linear drives. The linear drives eliminate the pulsation inherent in cam designs, resulting in much smoother pump strokes.

 

Easy Set-up

The UI-32 is designed for easy use and can be quickly set up by users with little to no technical assistance.

BP-11 Auto Backpressure Regulator

 

The BP-11 Auto Backpressure Regulator is an adjustable pressure regulator designed for liquid systems. It connects to the UI-22 Intelligent Pump to automatically maintain system pressure at a preset value. Utilizing a membrane powered by high-precision linear drives, it applies mechanical force to ensure superior response to pressure fluctuations from a post-reactor position.

 

Real-time Pressure Feedback

The BP-11 Auto Backpressure Regulator connects to the UI-22 Intelligent Pump's pressure sensor, providing real-time system pressure feedback.

 

Mechanical Force Regulation

Mechanical force is applied through a membrane powered by a linear drive, positioned after the flow reactor to maximize pressure control over the flow path.
