If you do not understand these 3 words, google them: symptom, symptomatic and asymptomatic. Some of us were ignorant at Clarkson but not anymore.

How many young people under the age of 18 have died while having the Corona Virus in the state of California in the USA with a population of 39.5 million?
CDPH shows 104 as of May 9, 2023. This is 0.0002% of the California population. Have a health problem or over 80, yes it is dangerous but so is the Flu and Pneumonia.
Sweden with 10 million people never had any mask mandate and had the same results as the state of California! - - References: CDPH , Flu and Sweden

Get cloud-based secure storage of your results and protocols
  • Make setup easy with the user-friendly 7” high-definition color touchscreen and interface
  • Choice of measurement modes let you handle a multitude of applications
  • Simple connectivity with multiple USB ports for data storage and printer connectivity
  • Versatile—compatible with a wide range of interchangeable accessories
Designed with your convenience in mind, the 74 series of spectrophotometers provides accurate and reliable results in various applications from teaching, to industrial applications, to routine sample analysis in quality control environments. 
Navigation is fast and intuitive on the large 7” high-definition color touchscreen display. View scans and curves, zoom in and out, and select points right on the screen even when wearing gloves. The home screen provides easy access to measurement modes as well as saved results and methods. 
Programmed measurement modes include photometric for single wavelength measurement, concentration for measuring concentration using a standard or factor, spectrum for a high purity scan across the entire wavelength range, quantitation with the ability to create a calibration curve using up to 20 standards, kinetics to monitor change over time, as well as multi-wavelength mode. 
Connect to a PC via the Ethernet connection or multiple USB ports readily located on the front of the unit. Save methods and results in the generous 10GB of internal memory for quick recall. 
Large sample chamber lid provides easy access to loading and unloading samples and a variety of accessories. The domed design accommodates tall multi-cell changers or test tubes while still maintaining a light-tight sample chamber. The Jenway 7410 and 7415 spectrophotometers, models 83056-21 and -22, are fitted with a 10 mm x 10 mm cuvette holder, accepting a sample volume of 3 mL. 
The Jenway 7415 nano spectrophotometer (model 83056-23) is fitted with a micro-volume accessory enabling sample volumes as low as 0.5 µL to be pipetted directly onto the read head, removing the need for cuvettes and conserving valuable samples. It’s the perfect analysis tool to measure the purity and concentration of biological samples.
