EZ-Stream™ Pump

The lab filtration pump that transfers filtered liquids directly to waste


Designed to improve operation time and comfort

Simply connect the pump to your manifold or filtration apparatus and place the discard tubing to drain and you are ready to filter. There is no need to use additional containers to capture the waste liquid. This brings a significant time saving versus traditional vacuum/pressure pumps or in-house vacuum because the following steps are eliminated: disconnecting the waste containers, emptying liquid waste, cleaning/decontaminating, re-installing the waste containers.

Thanks to its compact design the EZ-Stream™ pump is ideal for use both on the work bench and in the laminar flow hood where its small footprint (W 20cm – L 17cm – H 22cm) will save precious space.

The EZ-Stream™ pump is at home handling both liquids and gases making it also suitable for many additional Life Science Laboratory applications.

Regulatory compliance

Each individual pump is tested to ensure that the max vacuum delivered does not exceed 700 mbar, the vacuum pressure recommended in ISO 8199 (Water quality – general guidance on the enumeration of micro-organisms by culture).

A critical point in the microbiology laboratory, and aligned with GLP, is decontamination of equipment. The smooth design of the pump makes this operation easy and efficient. The EZ-Stream™ pump has been qualified to be compatible with a range of surface decontaminants.

Quiet design

Noise is often an issue when using filtration pumps. With the EZ-Stream™ a cover protects the pump mechanism, and the assembly has been optimized to reduce the noise down to 60 dB.

High vacuum performance

Thanks to its innovative design, the EZ-Stream™ pump can provide vacuum up to 600-700 mbar, and because it transfers liquids through the pump head this translates to a high flow rate performance. The pump can easily handle a multiple head manifold for water or beverage testing, providing a comparable flow rate to traditional vacuum/pressure pumps and a better flow rate when compared to other liquid pumps.


The EZ-Stream™ pump technology and the materials of construction provide reliable vacuum performance and make the pump maintenance-free. The diaphragm is made of highly durable chemically resistant polytetrafluoroethylene (PTFE).
