Voorbeeldzinnen

1. Evaporate to dryness, occasionally stirring with a glass rod.
2. Evaporate the dichloromethane extract down to dryness on the rotary evaporator (4.2) operating under reduced pressure at 40 oC.
3. Evaporate until it had just reached dryness, under reduced pressure at 60 oC by means of the rotary evaporator (4.3).
4. Evaporate this fraction until it had just reached dryness by means of the rotary evaporator (4.3) at 60 oC.
5. If any silica remains in the residue, redissolve it in a few millilitres of hydrofluoric acid (3.4) and evaporate to dryness.
6. Evaporate the solvent nearly to dryness on the rotary evaporator (4.1) with reduced pressure at a bath temperature not exceeding 40 oC.
7. Allow to cool, add a few drops of water followed by 10 to 15 ml of hydrofluoric acid (3.4) and evaporate to dryness at about 150 oC.
8. Dissolve the residue with about 2 ml of hydrochloric acid (3.1), evaporate to dryness and add 5 ml of 6 mol/litre hydrochloric acid (3.2).
9. Evaporate 100 ml of this extract on the rotary evaporator (see 5.4) nearly to dryness, remove the remaining solvent with a stream of nitrogen (3.10) and redissolve the residue in 10,0 ml of methanol (3.3).
10. For substances and mixtures which may cause concern as a result of skin dryness, flaking or cracking but which do not meet the criteria for skin irritancy in section 3.2 of Annex I, based on either:
11. The use of ‘shoe presses’ instead of conventional presses in the press-section of the paper mill allows SEL to reach a higher degree of dryness, it optimises the drying process and allows for energy saving.
12. Elute the robenidine from the column using 100 ml methanol (3.1), at a flow rate of 2 to 3 ml/minute and collect the eluate in a 250 ml round bottomed flask. Evaporate the methanol solution to dryness under reduced pressure at 40 oC by means of a rotary film evaporator (4.3).
13. Ambiguous reports simply of ‘irritation’ shall be excluded as this term is commonly used to describe a wide range of sensations including those such as smell, unpleasant taste, a tickling sensation, and dryness, which are outside the scope of classification for respiratory irritation;
