72 sieve and stored in desiccators
until further use.
If the readings repeat, the samples are considered to have reached the equilibrium moisture, where the partial pressure of water vapor of the product is equal to the partial pressure of ambient air steam inside the desiccator
After experiment, the airtight vacuum desiccators
were taken out and then connected with a vacuum pump (DOAP504-BN, GAST Manufacturing, A Unit of Idex Corporation, MI, USA) to extract the gas into a gas collecting bag.
The porcelain bowl had been dried first at temperature of 105[degrees]C for about 1 hour and, then desiccated in desiccators
for 30 minutes and scale up to constant weight (A).
Then a pair of tongs was used to transfer the dish into desiccators
, allowing it to cool down in the desiccators
for about half an hour.
Following, they were dried again in the oven and immediately transferred to a desiccators
after awhile, Individual bones weighed and were burned about 7 hours in a furnace at temperature of 550[degrees]C.
After 5-6 hours, the sample was removed and allowed to cool in desiccators
. Ashed for further few minutes and reweighed after cooling.
"At the high school level, we will be utilizing things like a hot water bath, desiccators
, rheostats and reference books, as well as supplies for experiments with drosophila and other living systems."
The metal catalyst (CO/[Al.sub.2][O.sub.3]) was then kept in desiccators
under dry condition.
Whole fresh fruits were placed in desiccators
. Saturated salts (lithium chloride, calcium chloride, magnesium chloride, magnesium nitrate, sodium chloride and potassium chloride) were used to maintain relative humidity ranging from 11 to 82 % in the desiccators
as stated by Ajibola (1989).
designs, manufactures and develops desiccators
, desiccant bags, humidity indicators and pressure relief valves.
Global Modular Systems currently includes components such as modular fluorescent lighting, cleanroom workstations and desiccators
cabinets in their product line.
