Milliflex Plus

Model : Milliflex® Plus | Category : Bioburden Testing | Brand : Merck Millipore


Evaluating downstream process quality involves multiple steps, whether in pharmaceutical, beverage, or microelectronic product manufacturing processes. Our compact Milliflex® Plus vacuum pump streamlines filtration steps during bioburden testing (microbial limit testing) to accelerate QC sampling. The vacuum pump and the convenient Milliflex® filtration funnels, when used together, comprise an integrated solution for delivering reliable, accurate results in high-throughput production environments.
These features of the Milliflex® Plus vacuum pump simplify your bioburden testing workflow:
  • Automatic, hands-off filtration for reduced testing time
  • Sanitary design with autoclavable pump heads
  • Modular pump head for greater filtration device flexibility
  • Internal calibration program to ensure accuracy

The key benefits of the Milliflex® Plus vacuum pump:

-Easy to use
By following simple text prompts that appear in the display window, operators can easily and quickly perform IQ and OQ validation and set filtration cycles. In routine sampling, pre-loaded testing programs control the pump through all of the filtration steps automatically. For fluids that require special handling, such as antibiotic solutions or other viscous liquids, a manual mode allows users to customize pump cycles to suit each SOP (standard operating procedure). The pump’s small footprint suits tight workspaces and its low profile allows easy access in laminar flow hoods, so filtration can be performed almost anywhere.

- Suited for high throughput testing
The built-in electronics ensure high productivity. In the automatic mode, filtration starts as soon as the specified sample volume is poured into the funnel, and stops after the determined volume has been processed. Vacuum release and dry cycles automatically terminate filtration without requiring any action by the operator.

Sanitization is easy, so the disruption to workflow is minimal. For even greater throughput, a high-volume workstation of up to three Milliflex® Plus pumps can be set up and used by a single operator. Tests have shown that 3 Milliflex® Plus pumps are faster than a 6-place manifold.
- Consistent results and traceability
A unique fluid management system ensures optimal performance and reproducible results. All system components that come into contact with the sample are either autoclavable or packaged and pre-sterilized to ensure the microbiologically best possible conditions for dependable results. An automatic dry cycle removes residual liquid to prevent cross-contamination. The fluid management system’s internal, weight-based calibration system withdraws and processes equal sample volumes to ensure consistency. The volume is displayed on the control keypad. The pump connects to a PC or printer, allowing all relevant data to be tracked and downloaded for easy report generation after filtration.

- Flexible, suiting all applications

For variations to testing requirements and for added flexibility, autoclavable pump head adapters for Millipore Sterisure™ and MicropreSure® filter units are available. Simply lift off the standard pump head and replace it with the one that fits the device.

- Validation support

Comprehensive protocols are available to make validation faster and easier. The validation protocol book contains ready-to-use installation, operation and performance qualification protocols that are written to the same standards as the protocols used to validate pharmaceutical processes.
