Where in the broth column is resazurin dye located?
In a typical broth column used for microbiological assays, resazurin dye is usually located in the upper portion of the column. This positioning allows it to be in contact with the microbial culture, where it can indicate metabolic activity through a color change. When microorganisms reduce resazurin, it changes from blue to pink, signaling their activity.
What color is resazurin in the presence of oxygen?

What does a blue or pink color in thioglycollate mean?

If the system was low and refrigerant and dye were added then you need to return to the shop so that they can check for leaks. That was the purpose of adding dye.
Why is resazurin a useful media additive for the study of anaerobes?
Resazurin is a useful media additive for studying anaerobes because it acts as an indicator of anaerobic conditions by changing color in the presence of oxygen. Anaerobes typically grow in environments devoid of oxygen, so the color change can help detect oxygen exposure. This allows researchers to monitor and maintain anaerobic conditions during experiments with anaerobic organisms.
How much does one dye weigh in kg?
The weight of one dye can vary significantly depending on the type and purpose of the dye.

Can you dye viscose?
eath to spandex. Either you will ruin your dress, or you will use inadequately hot water and end up with an ugly grey mess.Instead, use a cool water fiber reactive dye, such as Procion MX dye. Fiber reactive dye works much better than all-purpose dye on viscose rayon. All-purpose dye fades quickly and bleeds badly in the laundry, but fiber reactive dye is more intense in color and lasts through years of washing. Viscose rayon is dyed just like cotton, with the same dyes, but it is much more fragile when wet, so you must treat it very gently.You can find all-purpose dye almost anywhere, even grocery stores and pharmacies, but for a better dye you will have to look a little harder. You can buy fiber reactive dye in a crafts store or sewing store. Look for Dylon Cold Dye, Tulip One Step Fashion Dye, or Jacquard Procion dye, or get a tie-dye kit made by Jacquard, Dylon, Tulip, or Rainbow Rock. If you are in Australia, you can use Tintex Cold Dye, but don't use Tintex Hot Dye, and in North America don't use Tintex at all, because all of the Tintex dye available in North America is a hot water dye, unsuitable for your fiber blend. The best way to buy fiber reactive dye is to mail-order some Procion MX dye from one of the many companies listed on the page Sources of Dyeing Supplies Around the World.If you use a good dye, you can easily change the color of a coral dress to black, but the stitching will remain the original color. Would this look okay on your dress? Ready-made clothing is sewn together with polyester thread, which cannot be dyed with ordinary dye, nor at a temperature that will not destroy spandex.
