Extraction nozzle (Soxhlet) in accordance with GOST 25336.
Bath water.
A glass for weighing in accordance with GOST 25336.
3.6.3. Testing
Each sample of cotton wool is wrapped in degreased filter paper, placed in
extraction attachment so that the upper edge of the sample is not higher than the upper end of the siphon. Then the nozzle is connected to a tared flask and ethyl ether is poured in 1.5-1.7 volumes more than needed for pouring ether through a siphon. A weighed portion with a tared flask is connected to a refrigerator and extracted on a water bath for six transfusions of ether.
At the end of the extraction, the weighed portion of the cotton wool is removed, and the ether is distilled off from the flasks. A sample of cotton wool and a flask with the remaining fatty substances are kept in a fume hood until the smell of ether disappears.
A sample of cotton wool is placed in a tared bottle. The flask and bottle with an open lid are dried in an oven at 100-110 ° C until constant weight.
The first weighing is carried out after 3 hours, the next after 30 minutes. Before weighing the flasks and weighing bottles, closing the latter with lids, are placed for cooling in a desiccator for 10-15 minutes, then weighed on a laboratory balance.
3.6.4. Processing results
where t 2 is the mass of fatty and waxy substances after drying, g; t 3 - weight of the dried sample after extraction, g.
The test result is taken as the arithmetic mean of the test results of two determinations. If the discrepancy between the test results exceeds 0.05%, a third determination is made.
The arithmetic mean of the results of three determinations, calculated with an error of up to 0.001% and rounded to 0.01%, is taken as the final test result.
3.6.2-3.6.4. (Modified edition, Amendment No. 1). 3.7. Determination of moisture
3.7.1. Sampling - by and. 4 with the following addition:
The sample is taken:

3.8.3. Testing
Before testing to determine the actual moisture content, the first portion is dried to a constant dry mass. At the same time, the second air-dry sample is evenly laid out on the bottom surface of the funnel fixed in the tripod. The lower end of the funnel is closed with a stopper. Then, from a height of no more than 5 cm above the edge of the funnel, the sample is poured evenly over the entire surface to the brim with distilled water. After 10 minutes, the plug is removed, and then after 2-3 minutes
carefully turn the sample of cotton wool over to the other side with tweezers to allow water not bound to the fiber to drain into the glass for 10 minutes. Then a sample of cotton wool is transferred into a previously weighed dry cup, the mass of which should not exceed 50 g. The tests of two other weights are carried out in the same way.
3.8.4. Processing results
The absorbent capacity of cotton wool (K) in grams is calculated by the formula
t 4 (100 - Zh f) ’
where n is the amount of water absorbed by an air-dry sample of cotton wool, g; t 4 - weight of air-dry sample, g;
Lf is the actual moisture content of the cotton wool,%.

3.9.1. Ten portions weighing 0.5 g each are taken from the combined sample for tubes with a diameter of 7 mm. When using tubes of other diameters to maintain the established density in the tube, the weight of the sample of cotton wool (t 5) is calculated by the formula
where d is the diameter of the tube used, mm;
0.01 is the conversion factor for the sample weight.

Medical cotton wool (from German. Watte) - a fluffy mass of fibers, loosely intertwined in various directions, intended for use in hospital, outpatient and home conditions.
Distinguish hygroscopic hygienic medical, surgical and eye cotton wool.
Surgical cotton wool - white, easily exfoliated, used as a material that absorbs liquid discharge (pus), when dressing wounds over the layers of the bandage. In contact with skin and mucous membranes, it does not cause irritation. Has a uniform structure, no foreign inclusions, soft neck. Easily spreads in parallel layers. Cotton wool has a high sorption capacity, quite effectively absorbs and retains wound discharge, is well wetted both by wound exudate and solutions of drugs.
Cotton wool medical can be used to warm a tied or bandaged part of the body (for example, with warming compresses), as well as a soft lining when applying splints and immobilizing bandages (for example, plaster casts).
In production medical cotton - the raw material is cooked in alkali under pressure and then processed with sodium hyposulfite. As a result, the fiber acquires whiteness and characteristic properties - the ability to quickly wet and absorb liquids.
