GVS Life Sciences offers a range of disposable syringe filter devices designed to provide fast and efficient filtration of aqueous and organic solutions. They are available in a wide variety of sizes and membranes, with a polypropylene or acrylic housing, for both sterile and non sterile laboratory applications.
Features and Benefits:
Lower hold-up volume: Due to an improved flow channel design and reduced spacing between the supports within the housing, for better handling of small sample volumes or costly samples
Increased operating pressure: Up to 130 psi due to the over-mold that prevents sample leaking at the seam and keeps the lter unit from bursting in half
Strict quality control: Syringe lters are integrity tested to ensure a proper fit and weld to eliminate any potential filter by-pass
Accurate labeling: Each filter is labeled with the specific filter material and pore size for easy identification even if the syringe filter is not in its original packaging
Application
Filtration of Aqueous, Organic and Alcohol Solutions
Analytical Sample Preparation

th a cellulose swab and any bacteria collected are transferred via the swab into a tube containing a special medium with an indicator dye, which is then incubated. A single bacterium is sufficient to cause a color change. This means that SwabCheck is about 1000 times more sensitive than the conventional ATP method. This accuracy is particularly important in the food industry. With this simple method, it is possible to identify microorganisms such as Listeria monocytogenes, which must not be present in any concentration in food and beverages.
SwabCheck: how to use
Open the sterile pack, remove the swab and wipe it over an area of about 10 x 10 cm.Then twist off the cap of the medium tube and insert the swab so that the cap fits tightly. Label the sample tube and incubate at the appropriate temperature. A change in color indicates the presence of the microorganism in question. The quicker the color change occurs, the higher the bioburden. If no color change has been observed after the maximum incubation period has elapsed, then the corresponding microorganism is not present. GVS offers SwabCheck in packs of 25 pieces. With a shelf-life of 12 months.
