Glasses color code

Figure 1.16 Color-coded confocal Raman map of a 7.1 nm-thick PMMA layer (red) and a 4.2nm contaminant layer (green) on glass (blue). The map was computed from 200 x 200 spectra, with an integration time of 7 ms per spectrum, for a total acquisition time of 5.4min. Reproduced with permission from Ref [38].

Use puncture-resistant, leak-proof containers, color-coded red or labeled depending on the standard, to discard contaminated items such as needles, broken glass, scalpels, or other it s that could cause a cut or puncture wound. 

The limit of the transmission range of optical glasses towards the UV area is of special interest and is characterized by the position and slope of the UV absorption curve, which is described by a color code. The color code gives the wavelengths Xgo and X5, at which the transmission (including reflection losses) is 0.80 and 0.05, respectively, at 10 mm thickness. The color code 33/30 means, for example, A.go = 330nm and X5 = 300 nm. 

Figure 4 Comparisons of host cage topologies, (a) The hour glass-shape of Dianin s compound 8." (b) The ellipsoidal cavity of compound 13. (c) The Chinese lantern-shaped cavity of 21. In all cases, the molecules at the front and rear of the cage, and H atoms, have been omitted for clarity. Color code C, green (opposite enantiomCTs light or dark) O, red S, yellow. The (O-H)e cycles are indicated by red and white dashes.

Optical fibers can be plastic, i.e. methacrylate, or inorganic, i.e. glass for the visible spectral region and quartz for the UV region and range from 8 to 1000 pm in diameter. Some manufacturers use color codes to facilitate their identification (Figure 5.11) [2]. 

Fig. 8.3 PCA biplot of the elemental data, showing the significantly different elements (in black) projected into the score plot of the samples. Samples are color-coded according to their storage temperature (blue 10 °C, green 20 °C, red40 °C), and different symbols represent different packaging configurations filled circle 3 L bag-in-box triangle 0.75 L green glass bottle with...

They are also stable against imprinting of the sleeve fitting or Fingertight. They are pleasant to handle and the respective i.d.s are color-coded. However, with these capillaries there is a risk that the glass inside can fracture or break. Their high price has prevented ubiquitous deployment. 

A color-coded plastic bucket system has evolved to help route various wastes to their proper disposal sites and minimize injuries to custodial staff and waste handlers. This system includes using red buckets for mercury-contaminated materials yellow buckets for broken, non-contaminated glass white buckets for other hazardous wastes standard wastebaskets for ordinary trash and blue buckets for spill clean-up materials. Students are informed of these distinctions at the very beginning of lab each term and throughout the term as needed since all of these buckets are used in each teaching lab. 

Color-coded systems are used to label hazardous materials. Some labels use colored bars or diamonds that indicate the type of hazard. A red bar or diamond indicates a fire hazard. Yellow bars or diamonds indicate a reactivity hazard. Blue bars or diamonds indicate health hazards. White bars identify the need for personal protective equipment such as glasses, gloves, faceshields, rubber aprons, or respirators. A white diamond contains symbols regarding the health hazards the chemical may cause, warnings such as OX for oxidizer, ACID for acid, ALK for alkali, COR for corrosive, W for use no water, and a radioactive symbol.
