During the detailed design of the main and secondary functional elements the basic design, rules "simple" (e.g. use of a module system for the rack design, only 15% of the required components are specially made), "clear" (e.g. principle of the liquid flow did not lead to indefinable conditions) and "safe" (e.g. redundant arrangement of parts absorbing forces, double sealing of liquids) were met.
For these types of systems, there are three common elements: magmatic gas input, hydrothermal sealing, and vaporization of liquid water.
The outer diameter, DE1 of the central electrode E1 was chosen to be slightly greater than the inner diameter of the plastic tip Dit (i.e., DE1 ≤ Dit), thus sealing the flow of liquid through the probe.
The larger volume of the seal chamber increased the quantity of liquid around the mechanical seal.
Due to the corrosive nature and the high diffusivity of lithium, the corrosion attack on the seal and the physical permeation of liquid lithium through the seal are two main concerns for the proposed application.
Tight junctions (claudins and occludins) provide sealing against liquid leakage [ 6].
The durability of the magnetic fluid seal clearly decreases when sealing another liquid because of the interface instability caused by the applied magnetic field and the velocity difference of the two liquids.
These wells were sealed by pouring 20 μl of liquid nutrient agar medium in each well.
However, at present, some practical difficulties such as solvent evaporation, leakage of liquid electrolyte and sealing stability remain serious obstacles to their convenient application.
The straw is then labelled and heat-sealed before being frozen in a vapour of liquid nitrogen and, finally, deposited in a large grey metal tank of liquid nitrogen where it is stored at a temperature of -196C (-320F).
This was followed by sealing the water surface with a thin layer of liquid paraffin wax (Gene Chem., Canada) to avoid any diffusion of oxygen from the atmosphere.
