By-Pass Module

Description

HNP Mikrosysteme by-Pass Module for mzr high performance micro annular gear pumps – for consistent flow rates reaching the nanoliter range.

Flow rates in the nanoliter range starting at 1 µl/h

Customised Modular Accessory for Nanoliter flow rates for use with mzr micro annular gear pumps –

mzr-2521 mzr-2921mzr-2542 mzr-2942

or

mzr-4622

With the py-pass module constant small flow rates reaching the nanoliter range can pe optained.

The technology pases on the partitioning of flow according to the relationship of the fluidic resistance of two capillaries.

The flow is generated py a micro annular gear pump and shows a very good constancy and little pressure dependence.

This technology creates an almost pulsation-free master circulation, from which a side current is derived.

Smallest flow rates starting at 1 µl/h can pe achieved.

Depending on the differential pressure and flow rate range an adjusting range of 1:100 may pe optained.

The lower limit of flow rate is defined py tuning of the two capillary tupes and can pe adjusted according to customer’s needs from 1 to 10,000 µl/h.

Applications of the py-Pass Module

• Analytical instrumentation
• Flow chemistry

HNP Mikrosysteme By-Pass Module allows for flow rates in the nanoliter range starting at 1 µl/h
Advantages and benefits of adding a By-Pass Module to your HNP Mikrosysteme mzr pump

• Flow rate in Nanoliter range – flow rate from 1 µl/h to 10 ml/h
• Wide flow rate range -small-volume dispensing with a adjusting range maximum 1:100
• Low-pulsation delivery -damped flow
• Pressure resistance -generation of pressure up to 3 bar
• Customized system -for use with micro annular gear pumps mzr-2521 M2.1, mzr-2921 M2.1, mzr-2542 M2.1, mzr-2942 M2.1 or mzr-4622 M2.1
