Millipore Filter Apparatus
Product Code : SCL-CLE-11899
The StemAids Millipore-Style Filter Apparatus (Vacuum Filtration Set) is a precision-engineered laboratory system designed for the separation of fine particulates, microorganisms, and precipitates from liquid media. Utilizing membrane filtration technology, it allows for the sterilization of heat-sensitive biological fluids and the clarification of HPLC solvents. Manufactured to ISO 9001:2015 standards, this assembly is a critical asset for University Microbiology, Environmental Science, and Pharmaceutical laboratories.

Key Pedagogical & Laboratory Outcomes
- Microbiological Interface: Facilitates the Sterilization of culture media. By using a 22μm membrane, learners identify how physical barriers can remove bacteria and fungi from liquids without the denaturing effects of heat.
- Environmental Quantification: Enables Total Suspended Solids (TSS) analysis; learners apply the apparatus to filter water samples, weighing the membrane before and after to quantify pollution levels.
- Phase Analysis: Supports the analysis of "Particulate Contamination"; students evaluate the purity of solvents required for sensitive analytical instruments like HPLC or Spectrophotometers.
- Pressure Differential Evaluation: Allows students to evaluate the physics of vacuum-assisted filtration, observing how the pressure gradient accelerates the flow rate compared to standard gravity filtration.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, high-impact packaging. Each component (funnel, flask, clamp, and base) is nested in custom-cut high-density foam to prevent fracture during international maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a technical guide for membrane selection.
- Durability: The Borosilicate 3.3 glass is annealed to withstand the structural stress of a full vacuum without the risk of implosion.
Direct OEM Sourcing Advantages
Procuring the StemAids Millipore Filter Apparatus directly ensures vertical manufacturing control:
- Precision-Ground Joints: Direct oversight of the mating surfaces between the funnel and the base ensures a vacuum-tight seal, preventing "bypass" or leakage during critical sterilization runs.
- Uniform Frit Porosity: We utilize high-quality sintered glass discs that provide an even flow rate across the entire membrane surface, preventing "hot spotting" or premature membrane clogging.
- Direct Factory Inventory: Guaranteed availability of replacement parts, such as aluminum clamps or sintered bases, ensuring your laboratory maintains 100\text{%}
- Quality Assurance: Every flask and funnel is pressure-tested and inspected for "seeds" or striations in the glass that could compromise safety under vacuum.
