A stomacher blender is a laboratory instrument used for microbiological sample preparation. It works by mechanically homogenizing samples placed in a sterile plastic bag inside the device. The paddles then apply pressure and friction to the bag, homogenizing the sample.
Also called a paddle blender or laboratory paddle blender, the stomacher blender uses a motor to drive two paddles that squeeze the sample in the plastic bag against a curved surface. The bag is kept sealed to prevent contamination during the process. The laboratory paddle blender is typically run for a few minutes to ensure complete homogenization.
The stomacher blender is commonly used in clinical, life science, food, and environmental microbiology laboratories. In the food industry, it is used to test the microbiological quality of food products; it is also employed in medical and environmental laboratories. For example, it is used in microbiology laboratories to extract and wash intact microbes into solution. It provides 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. These machines handle sample volumes from 3 to 400 ml. Each instrument features a color touchscreen LCD controller with an interactive menu. The paddle blenders offer programmable time settings and adjustable slapping speeds. These units are safe, easy to operate, and require no maintenance; in addition, our stomacher blender prices are competitive in India.
