What is the purpose of the trap in Figure 2-17 and the watch glass in Figure 2-20?

Short Answer

Expert verified

The trap, as shown in Figure 2-15, prevents the backing of tap water into the suction flask from the aspirator. It also prevents liquid in the suction flask from being sucked up into the vacuum system. Figure 2-18 shows how the watch glass is used to reduce dust contamination.

Step by step solution

01

Definition of vacuum system

Vacuum systems are made out of vacuum pumps and tanks positioned on a skid or a vehicle. A vacuum pump generates a vacuum in the tank, and the oil flows straight from the skimmer or the source of the oil to the tank through a hose or pipe.

02

Explanation of the purpose

In this task, look at the trap in Figure 2-17 and the watch glass in Figure 2-20 of the book.

The trap, as shown in Figure 2-15, prevents tap water from backing up into the suction flask from the aspirator, as well as liquid in the suction flask from being sucked up into the vacuum system.

As shown in Figure 2-18, a watch glass is utilised to reduce dust contamination by keeping dust out of the sample.

Molecular mass by sodium dodecylsulfate–gel electrophoresis. Ferritin is a hollow iron-storage protein 74 consisting of 24 subunits that are a variable mixture of heavy (H) and light (L) chains,arranged in octahedral symmetry. The hollow center, with a diameter of 8 nm, can hold up to 4 500 iron atoms in the approximate form of the mineral ferrihydrite (5Fe1O3×9H2O)Iron(II) enters the protein through eight pores located on the threefold symmetry axes of the octahedron. Oxidation to Fe(III) occurs at catalytic sites on the H chains. Other sites on the inside of the L chains appear to nucleate the crystallization of ferrihydrite. Migration times for protein standards and the ferritin subunits are given in the table. Prepare a graph of log(molecular mass) versus 1/(relative migration time), where relative migration time 5 (migration time)/(migration time of marker dye). Compute the molecular mass of the ferritin light and heavy chains. The masses of the chains, computed from amino acid sequences, are 19 766 and 21 099 Da.
