After that the crucible was taken out and cooled to room temperature in a desiccator
. The crucible was weighed again.
Formaldehyde emission is the amount of formaldehyde released from wood-based panels to a certain volume of air or a certain amount of water within a specified period of time, which is always tested by using chamber or desiccator
After the dehydration process, the specimens were dried based on physical dehydration by using CPD technique with one process for 4 specimens for 1 hour, mounted on circular stainless steel moulds, coated with 10 nm of pure gold in a vacuum sputter coater, and kept in a desiccator
or under vacuum to minimize artifacts caused by rehydration of the tissues from native humidity before FE-SEM/EDX data were taken using Quanta FEG 250.
For the fibres kept at 50[degrees]C, the moisture loss is much more rapid than that in a desiccator
. As shown in Figure 3, the moisture loss at 50[degrees]C starts to stabilise after about 200 minutes, when the fibres have lost almost 4% of the moisture, as the amount of moisture in the fibres starts to decrease.
After heating, it was then cooled in a desiccator
for 30 minutes.
Veneer moisture conditioning chambers consisted of plastic desiccators
(height 311 mm, flange diameter 225 mm, Fischer Scientific Company, Pittsburgh, Pennsylvania) with a 12.5-mm square cooling fan (RadioShack, Fort Worth, Texas) suspended on the desiccators
' perforated plastic platform (divider) on four stainless legs.
After the slugs were weighed, the bags containing the slugs were placed on a porcelain ring in an 11 L desiccator
with [approximately equal to]2.3 kg of anhydrous CaS[O.sub.4] that was used to maintain the air inside the desiccator
at 0-2% RH.
Known weights of each of the samples were introduced into a desiccator
containing a saturated solution of sodium chloride.
The method that takes the least amount of time and equipment and still gives a crisp chip is using a very hot (475 degrees or higher) oven or a desiccator
(a drying oven).
The Secador[R] Mini Desiccator
is ideal for safe storage of valuable moisture sensitive chemicals and electronics.
The solvent was removed in a desiccator
attached to a vacuum pump to give a white residue.
