Desiccator

On my first day, Professor Hirata brought out a large vacuum desiccator and said, "This contains dried Cypridina." ❋ Unknown (2009)

Two big air conditioners and a desiccator run constantly to keep it at 50 degrees F, and 30% Rh. ❋ Scribe (2008)

The bottle is capped with its tight-fitting stopper when it is outside the desiccator so that moisture won't get inside. ❋ AYDIN (2007)

This is how I learned to do it way back when: First, you dry the empty bottle to a constant weight, then you add the substance to be weighed in it and place the bottle in a desiccator until its weight stops changing. ❋ AYDIN (2007)

It is left upon the bath until all the moisture has been driven off, then it is allowed to cool for about half-an-hour in a desiccator and is weighed. ❋ Unknown (N/A)

It was then warmed on a water-oven, kept in a vacuum desiccator over solid paraffin, and the weight estimated. ❋ C. F. Cross (N/A)

Ten minutes later connect up the desiccator to a sulphuric acid wash-bottle interposing an air filter so that only dry sterile air enters. ❋ Unknown (N/A)

I have kept one very conveniently in a vacuum desiccator over phosphorus pentoxide, but if of any size, the condenser deserves a box to itself, and this must be air-tight and provided with a drying reagent, so arranged that it can be removed through a manhole of some sort. ❋ Richard Threlfall (N/A)

Reseal the desiccator and again exhaust, and subsequently admit dry sterile air as before. ❋ Unknown (N/A)

When very accurate dry matter determinations are desired, the substance is dried in a vacuum oven, or in a desiccator over sulphuric acid, or in an atmosphere of some non-oxidizing gas, as hydrogen. ❋ Harry Snyder (N/A)

The method of analysis is as follows: -- Weigh out 10 grms. of the substance, previously cut up into small pieces with a platinum spatula, and place over calcium chloride in a desiccator for some days. ❋ Unknown (N/A)

It was, however, found impossible to obtain any crystallisation from the neutralised (BaCO_ {3}) and concentrated solution, the syrup being kept for some weeks in a desiccator. ❋ C. F. Cross (N/A)

At the end of such time the sample should be placed in a desiccator containing calcium chloride, and when cooled should be weighed. ❋ Unknown (N/A)

After cooling in a desiccator, it is weighed again. ❋ Various (N/A)

_ -- The platinum bowl is washed with nitric acid and distilled water, dried by heat, and then left to cool in a desiccator. ❋ Various (N/A)

The hydrochlorate gives up a part of its water of crystallization at the ordinary temperature under a desiccator over sulphuric acid, and the whole of it upon heating. ❋ Various (N/A)

A sample cut from a cartridge, about 1 inch long, should be placed under a glass shade, together with water (a large desiccator, in fact), and left for some days. ❋ Unknown (N/A)
