A standard method of determining the presence of microorganisms is to filter samples throughout brewing processes to isolate potential bacterial contamination. These samples are then plated and incubated. This method is known as the membrane filter (MF) technique. Membrane filters are selected based on their pore size to isolate specific microorganisms. The MF technique is applicable to many organisms including bacteria, yeast, and fungi.
The MF technique provides rapid and efficient detection and quantification of microorganisms. It is highly sensitive and can detect low concentrations of bacterial contamination, which is critical for quality control in beverage production.
The technique is also cost-effective, requires minimal media preparation, and allows for larger sample volumes to be tested. The MF technique can also detect specific microbial species by using selective media.
The choice of workflow used by microbiologists is based on several factors including product handling preferences, laboratory efficiency, cost per test, recovery of organisms, and controlling sample-to-sample cross-contamination.
The MF technique can be performed with reusable hardware. A membrane disc is placed into a reusable funnel that has been previously autoclaved. The sample is then filtered and the membrane transferred to a petri dish.
Filter dispensers are ideal for high throughput microbiology testing labs that are looking for an ergonomic and faster way to handle individual membranes. Our Sentino™ filter dispenser is designed to aseptically dispense one sterile membrane disc at the touch of a button.
Built with features that make your job easier, the Sentino filter dispenser has membrane guide plates and independent spools that make it easy to load and reliably dispense without misalignment or jamming.
Its compact design takes up less space on a crowded benchtop. The unit can be battery or main power operated and features a central soft-touch keypad that suits both left and right handed users.
With its easy to replace membrane refill packs and an easy to clean design, the Sentino filter dispenser suits any busy microbiology laboratory. It combines ease-of-use, aseptic membrane delivery, and waste collection.
The Sentino filter dispenser can be used in the MF technique for microbial testing in various applications, including:
- Drinking and wastewater analysis
- Environmental and recreational water monitoring
- Beverage monitoring
- Personal care product manufacturing
- Pharmaceutical and industrial water system monitoring
- Pharmaceutical raw materials, intermediates, and final product
Speedy and robust quality control
