Then it was cooled to room temperature in a desiccator
and weighed again to estimate the ash content.
Chinese standards of wood-based panel have E0 level in GB/T 5849-2006 "Block board" and GB/T 15104-2006 "Decorative Veneer decorated wood-based panel," which use desiccator
method to test formaldehyde.
Then we have put Petri dish into a desiccator
, in the bottom of which distilled water is poured, and put the desiccator
into the thermostat at a temperature of 30 [+ or -] 2[degrees]C.
Dark green coloured precipitates so obtained were filtered, washed with acetone, and dried over anhydrous calcium chloride in a vacuum desiccator
at room temperature.
This is done by coating them with an extremely thin layer (1.5-3.0 nm) of gold or gold-palladium and saving them in desiccator
Weight Loss in a Desiccator
. The weight loss behaviour of hemp fibres in a desiccator
was observed by keeping a sample of hemp fibres, cut out from hemp fibre mat conditioned at 23[degrees]C and 50% relative humidity (RH), in the desiccator
containing the desiccant copper sulphate and recording weight changes with the passage of time.
It was then cooled in the desiccator
for 30 minutes.
800 and 1500 sandpaper, rinsed with distilled water, and then cleaned ultrasonically in acetone and dried in a desiccator
at 80[degrees]C for 12 h.
The cups are placed in a desiccator
to initiate the water permeation through the film.
The optical elements are protected from humidity and stabilized by a sealed interferometer, continuously removing moisture by a reactive polymeric desiccator
, and coating the beam splitter with moisture-resistant protective film.
Veneer samples with MCs below the fiber saturation points (FSP) were obtained by conditioning green veneer samples in a desiccator
(225-mm diameter) in which the relative humidity of its chamber is affected by use of saturated inorganic salts solutions as shown in Figure 1.
