Matters needing attention when using the electrolytic cell of MA-2A automatic moisture analyzer:
(1) If the electrolyte in the cathode chamber is found to release strong bubbles or the electrolyte is contaminated into brown during the titration, the blank current will increase, the reproducibility of the measurement will decrease, and the time to reach the end point Lengthen, this situation should be replaced as soon as possible.
(2) The titration time is more than half an hour, and the instrument is not stable. At this time, the stirring should be stopped to observe whether there is obvious brown iodine generated under the platinum mesh under the electrolytic electrode. If there is no or little iodine production, the electrolyte should be replaced.
(3) Care must be taken when changing reagents, do not contact with skin, rinse thoroughly with water after contact. Because the reagent has a strong smell and contains toxic ingredients, the laboratory should be well ventilated.
A wooden box is a container made of wood for storage or as a shipping container.
Construction may include several types of wood; lumber (timber), plywood, engineered woods, etc. For some purposes, decorative woods are used.
Boxes and crates are not the same. If the sheathing of the container (plywood, lumber, etc.) can be removed, and a framed structure will remain standing, the container would likely be termed a crate. If removal of the sheathing resulted in there being no way of fastening the lumber around the edges of the container, the container would likely be termed a wooden box.
The strength of a wooden box is rated based on the weight it can carry before the cap (top, ends, and sides) is installed. "Skids" or thick bottom runners, are sometimes specified to allow forklift trucks access for lifting.
Performance is strongly influenced by the specific design, type of wood, type of fasteners (nails, etc.), workmanship, etc.
Some boxes have handles, hand holes, or hand holds.
