The component of umami, glutamic acid, is an important amino acid that determines the deliciousness of food. It is abundantly found in meat and vegetables and is used in a variety of processed foods as a seasoning. This product has developed a kit that allows for easy measurement of the approximate concentration of glutamic acid. 【Features】 ■ You can easily measure the concentration of glutamic acid in food and beverages using the test kit. ■ Applicable for analysis of medium components in biological samples and cell cultures. ■ Simply dilute the food you want to measure with water, dip the test strip, and wait for 10 minutes. ■ The concentration in the sample is calculated based on the concentration obtained from the color standard. ■ A sample kit is available for first-time customers. *For more details, please contact us or view the PDF data from the download.

The liquid quantification sampling stick "Paper Pipette" allows for the collection of a specific amount of trace liquids that require dilution. No special equipment is needed, and by taking a fixed amount of liquid and mixing it with water or similar, you can create dilution solutions of 100 times or 1000 times. 【Simple 3-Step Testing Process】 1. Dip into the liquid to be diluted for 5 seconds. 2. Remove the Paper Pipette. 3. Mix in water or similar liquid for 10 seconds to achieve uniformity. 【Examples of Use Cases】 ■ For food analysis - Dilution for measuring L-glutamic acid concentration in food and beverages. - Dilution for measuring glucose concentration in beverages. - Dilution for testing solutions in food allergen testing. ■ For sampling water in environments such as rivers and ponds. ■ For sampling media for the analysis of microorganisms and cell culture solutions. *For more details, please request materials or view the PDF data available for download.
