Absorbance measurement device
This is a spectrophotometer that allows for easy measurement of absorbance. With a light source and CCD spectrometer, it enables fast and high-precision absorbance measurements in the range of 200nm to 1100nm. By simply setting the included cell containing the solution into the main unit, you can immediately obtain the absorbance.
This is a spectrophotometer, a measuring instrument suitable for absorbance measurement (OD meter). The measurable range for OD is from 0 to 8, with an optional extension up to 12!
The "DD8-N" is a spectrophotometry measurement system (OD meter) that can evaluate absorbance (OD) and transmittance without the need for a darkroom, and it also allows for real-time display. It provides stable measurements by canceling external light and noise using a chopper method, enabling highly accurate measurements of extremely small transmittance. It supports various options and custom specifications, including multi-point measurements, polarimetry measurements with polarizing prisms, and reflectance measurements. 【Features】 ■ Measures ultra-weak light from 8OD to 12OD without a darkroom ■ Can cancel external light and noise ■ Calculates optical density from the transmittance of the sample relative to a reference ■ Continuous measurements can be taken at arbitrary intervals ■ Supports various options and custom specifications *For more details, please refer to the PDF document or feel free to contact us.
High reliability, speed, and simplicity! A compact spectrophotometer that can be measured in various locations according to the application.
The "Absorptlyzer" is a portable small spectrometer capable of measurements both indoors and outdoors. Measuring 122mm (W) x 57mm (D) x 63mm (H) and weighing 150g, it can be used in various locations due to its compact and lightweight size. Additionally, it operates via USB connection. 【Features】 ■ Compact and lightweight size ■ Operates via USB connection ■ Capable of measurements indoors and outdoors ■ Low power consumption ■ Cost reduction possible *For more details, please refer to the PDF document or feel free to contact us.
Research is underway to develop agents that effectively kill bacteria in biofilms and suppress their production!
We would like to introduce our analysis related to biofilms, specifically the "Evaluation Method for Bacterial Sterilization and Growth Inhibition in Biofilms." The sterilization effect is evaluated by measuring the metabolic activity of the bacteria. WST (water-soluble tetrazolium salt) is one of the reagents used to determine bacterial metabolic activity, producing WST formazan in accordance with the metabolic activity of the bacteria. By measuring the absorbance, we can determine the amount of surviving bacteria. 【Analysis Method】 1. Immerse the substrate or pin in the bacterial culture solution and incubate at a constant temperature for 24 to 48 hours to allow biofilm formation on the substrate or pin. 2. After immersing the substrate or pin in the sterilizing agent solution for a specified time, wash it with water. 3. Immerse the substrate or pin in the WST reagent for 10 to 60 minutes. 4. Measure the absorbance at 460 nm. 5. Compare the standard solution with the amount of biofilm. *For more details, please refer to the PDF document or feel free to contact us.
