A stomacher blender is a laboratory device used for microbiological sample preparation. It works by mechanically homogenizing samples in a sterile plastic bag, which is then placed in the stomacher blender. The blender then applies pressure and friction to the sample, causing the sample to be homogenized.
The stomacher blender works by using a motor to drive two paddles that squeeze the sample contained in the plastic bag against a curved surface. The bag containing the sample is placed in a sterile container to prevent contamination during the blending process. The stomacher blender is then operated for a set period of time, usually a few minutes, to ensure complete homogenization of the sample.
The stomacher blender is commonly used in clinical and life science, food and environmental microbiology laboratories. In the food industry for testing the microbiological quality of food products, as well as in medical and environmental laboratories. For example, in microbiology laboratories to extract and wash intact microbes into solution. it is used It is an effective way to extract microorganisms from a wide range of samples, including food, water, soil, and clinical specimens.
The step by step working of a stomacher blender has explained here:
- Sample Preparation: Sample preparation is the first step of a stomacher blender which involve placing of biological or food sample inside a sterile plastic bag or pouch. The bag may contain a diluent or buffer solution, depending on the type of sample and the purpose of the blending.
- Bag Insertion: Second step involves insertion of sample-filled bag into the stomacher blender machine.
- Stomaching Process: This is to ensure that The lid is closed securely, and the blending or stomaching cycle is initiated. The laboratory stomacher blender contains two paddles or plates known as stomacher paddles that are designed to strike or impact the sample-filled bag in an alternating motion.
- Agitation and Pressure: The stomacher paddles rapidly move back and forth, applying pressure to the sample within the bag. The impact and squeezing action of the paddles help break down the sample, releasing cells, microorganisms, or other constituents into the surrounding liquid.
- Blending Process Time: The duration of the blending cycle varies depending on the specific application and sample type. It can range from a few seconds to several minutes. Our stomacher blender has programmable timing function in-built achieve thorough mixing and homogenization of the sample.
- Sample Extraction: After the blending cycle is complete, the bag is removed from the stomacher blender by switching off the machine and opening the lid. The liquid containing the homogenized sample is then ready for further analysis or processing, such as microbial enumeration, DNA extraction, or protein isolation.
Our stomacher paddle blenders are designed to meet industry standards for sample processing. Our paddle blender machines are designed for 3 to 400 ml sample volumes. Each instrument features color touch screen LCD controller with interactive menu. We have 3 models and each stomacher blender model is fitted with microprocessor based LCD controller. These machines come with programmable time settings and slapping speed adjustment. These units are safe, easy to operate and require no maintenance; in addition, our paddle blender price is competitive in India
