The new Binary Pump Module (BPMTM) has been designed to offer the flow chemist maximum flexibility. It may be used

either as a two-channel upgrade in combination with any FlowSyn system (to give four identical reagent channels in total), or completely independently as a stand-alone dual reagent delivery module.

The BPM is solidly engineered using well-established components of proven reliability. Three in-built pressure transducers

constantly monitor pressure and system performance so ensuring safety and peace of mind.

The standard unit (UQ1022) is plumbed with stainless steel tubing, delivers flow rates from 5 ?L/min up to 10 mL/min and

can operate at up to 100 bar (1400 psi) . A 200 bar (2800 psi) version is also available (UQ1022-200).

The BPM Maxi (UQ1023) delivers flow rates of up to 50 mL/min per channel and is limited to 100 bar.

Alternative configurations are available that offer either all perfluoropolymer or all Hastelloy flow paths.

On request, units can even be supplied with flow paths constructed of two different materials (for specific chemical

compatibilities) in the same module.

Features:

Integrated in-line mixing module

System back pressure regulator and low pressure outlet selection valve (Collect/Waste)

Three separate fluidic circuits – to facilitate pump priming ‘on the fly’ without the need

to cool/depressurise the reactor(s)

Robust – all stainless steel construction.

Each pumping channel is identical and has:

A low pressure inlet reagent/solvent selection valve

A high pressure chemically resistant injection valve with 1.0 mm fluidic channels

An in-line pressure transducer and priming port

Automatic air bubble detection (ABD) algorithm.

Fully Integrated Flow Mode

When the BPM is connected to a FlowSyn, basic control of the four identical flow channels can be achieved directly

through the FlowSyn user interface.

A new PC-based control interface that allows the user to program combinatorial experiments using all four flow channels

will be released shortly.

Standalone Flow Mode

As a stand-alone reagent delivery module, system control is through dedicated software running on a PC. The BPM is able

to control a fraction collector directly and can be used as a hub through which to control a customer’s own flow reactor

system.

For example, the Uniqsis BPM Maxi (2 x 50 ml/min) might be combined with a Uniqsis Cold Coil to constitute a flow system

suitable for low temperature scale-up work in which the reactor temperature is controlled by an external mechanical

heater/chiller.
