A good weighing process ensures that ingredients are added in the right order, minimizing waste and ensuring quality. It also helps businesses reduce raw materials costs and boost their bottom line.
Weighing systems combine advanced controls with weighing sensors to accurately weigh and dispense material into a batch. These systems are essential for production processes involving hazard materials.
Direct weighing
If you need to weigh a solid substance that is not hygroscopic or stable in air, you can use the direct weighing method on a modern analytical balance. This method works by placing a clean piece of weighing paper on the pan and then adding the substance to be weighed. After the first reading is taken, the weighing paper is removed and the new mass is subtracted from the original to obtain the sample’s mass.
This process requires care and coordination, and it is essential that the hands used to handle the substance are clean and free of moisture, grease, or dirt. These particles can cause a false weight reading by disrupting the balance’s stability.
To avoid these problems, it is advisable to tare the balance before using it. The tare button subtracts the weight of the weighing paper and the beaker, leaving just the sample’s mass displayed on the display. You should also close the balance door to prevent dust and air currents from disturbing the reading.
Ordering ingredients
Whether you are in the pharmaceutical, manufacturing, jewellery or food industry, choosing the right weighing method is critical to your success. The precision needs of your application and the characteristics of the substances you work with will influence which weighing technique you should apply. If you require the utmost accuracy and contamination control, Weighing by Difference is your best bet. However, if speed and convenience are more important, Direct Weighing is a pragmatic solution. This simple process eliminates the need for additional steps like taring and is perfect for applications that demand quick measurements.
To perform a direct measurement, first tare the balance to zero and then put your sample on a weighing paper or a container. Then close the door and measure the weight of your sample.
Biotechnological experiments
Biotechnology combines biology and technology to create new products and processes. It is used in health care, agriculture, and industry. It also offers new opportunities for addressing environmental issues. It can help reduce waste and improve food and energy security. It is also being used to develop sustainable chemicals and biofuels.
Medical biotechnology uses living cells and their parts to develop medicines, vaccines, and other healthcare products. It can also be used to grow artificial tissues. Medical biotechnology also includes genetic testing and karyotyping.
In this experiment, students will learn about DNA restriction analysis using a simple technique that is based on the Watson-Crick structure of DNA. They will use restriction enzymes (the scissors of molecular biologists) to cut DNA from the bacteriophage lambda and then run a gel electrophoresis to separate the fragments. Teachers can access this lab by clicking the “Experiment Title” link and submitting a LCCC SIM request for equipment.
Automated weighing
Whether it’s a check weighing system that ensures packages fall within target weight ranges or an unattended truck scale kiosk, automated systems can help your business complete essential tasks without involving a human. This helps to improve inventory management & quality control processes as well as ensure compliance with industry standards.
Core components of an automated weighing system include load cells that measure the material or product’s weight and an automation terminal that converts the electrical signals into readable data. These devices are often found in tank & hopper scales, bench, floor or conveyor scales.
Automation terminals like METTLER TOLEDO’s IND360 feature AOI (add-on instructions) that reduce the amount of PLC programming required for a smart weighing device. This allows engineers to focus on weighing process optimization. In addition, IE (industrial Ethernet) integration offers tested & optimized protocols that streamline communications with PLCs. This helps to save engineering time & effort and increases system reliability and performance.
