Funnel

funnels with an internal diameter not less than 12 cm, to support the sieves,

A tap-funnel E for introduction of the liquid to be treated and the alkaline solution.

THE FUNNEL SHALL BE FILLED FROM THE EDGE WITH DIGESTIVE LIQUID UNTIL THE MATTER FOR ANALYSIS IS COMPLETELY COVERED.

Phytosociological characteristics of holm oak Quercus ilex L. stands on Mount Sabotin and above the source of the Lijak river (Western Slovenia)

Applying the standard Central European phytosociological method, we researched holm oak Quercus ilex L. sites at its northernmost localities in Slovenia on the slopes of Mount Sabotin above the Soèa Valley and above the source of the Lijak River in the Vipava Valley.

On the basis of the analyses and comparisons, the holm oak stands on Mount Sabotin and above the source of the Lijak were syntaxonomically classified in a new variant Ostryo-Quercetum pubescentis (Ht. 1950) Trinajsti 1974 quercetosum ilicis Lausi and Poldini 1962 var. Amelanchier ovalis var. nova.

a suitable sink with drainage;

Boil the mixture for approximately 45 minutes, leave to cool and filter through a Buchner funnel.

Filter under vacuum over a filter plate covered with a wire mesh (4.4) and placed in the funnel of a vacuum flask (4.3).

Collect 50 ml of filtrate in a 50 ml volumetric flask and transfer quantitatively to a 150 ml separating funnel, using 50 ml of diethyl ether (3.1).

Weigh 15 g of the sample to the nearest 5 mg and place in a container with a capacity of approximately 200 ml, fitted with a ground-glass stopper (e.g. a separating funnel).

Add to the ammoniacal solution 50 ml of silver nitrate solution 0.1 N (3.5) (or more if necessary), place a small funnel over the volumetric flask and heat the mixture over a boiling water bath for one hour.

Stir, and transfer the contents of the beakers to separate columns or funnels (5.1.4) each containing about 1 g silica gel (4.4);

Rubber-stoppered vacuum flasks of approximately 2 litre capacity, with measuring marks at the 800 ml level and fitted with glass funnels 120 mm in diameter.

magnetic stirrers, with thermostatically controlled heating plate and teflon coated stirring rods, approximately 5 cm long, - conical separation funnels of 2 litre capacity,

Filter plates approximately 40 mm in diameter and approximately 4 mm thick, with slanting edges to fit the cone of the funnel (4.3), perforated with approximately 16 holes, each approximately 4 mm in diameter, and covered by a wire mesh, the mesh size being approximately 1 mm. Both plates and wire mesh must be resistant to acids and alkalis.

Trawl body (= net cone)

a conical separation funnel of 2 000 ml capacity,

a funnel with an internal diameter of not less than 12 cm,

(The funnel is rinsed with detergent solution after use).

The digestion fluid is poured into the Gelman funnel and filtered.

1 litre Gelman funnel, complete with filter holder (diameter 45 mm),

Plastic washbasins

Allow to stand for 20 minutes, then strain through a folded filter or a Buchner funnel.

Then filter on a Buchner funnel fitted with a filtering aid or on a sintered filter.

Baths, shower-baths and wash-basins

The chilled digestion fluid is transferred to a 2 litre separation funnel, equipped with a vibrator in an extra clamp.

The Gelman funnel, fitted with a filter holder and filter disc, is mounted on the Erlenymeyer flask connected to a filter pump.

The digested solution shall be filtered through the sieve into the conical 2 litre separation funnel and left undisturbed on the stand for at least one hour.

The digestion fluid is stirred for 30 minutes, at the end of which the stirrer is switched off and the digestion fluid is poured through the sieve into the sedimentation funnel.

Sedimentation for 30 minutes, during which time the sedimentation funnel is vibrated intermittently, i.e. one minute vibration followed by one minute pause.

Plastic baths, shower basins or washbasins

conical separation funnels of 2 litre capacity,

The digestion fluid is allowed to stand in the funnel for 30 minutes.

- calibrated microsyringe or micropipette with appropriate tips,

The tap of the dropping funnel is opened to let the water into the conical flask and a stop watch is started.

Run 15 ml of Orthophosphoric acid (3.2) from the funnel into the distillation flask A.

The size of the funnel and sieve is such as to ensure that only a few granules lie one above another and the oil is able to drain easily.

conical separation funnels of 2 litre capacity, preferably fitted with teflon safety plugs,

Suction should cease before the filter becomes dry, i.e. when 2 to 5 ml of fluid are left in the funnel.

The residue inside the funnel is washed 3 × 10 ml with diethyl ether collecting the filtrate in the same flask fitted to the funnel.

Baths, shower baths, wash-basins, bidets, lavatory pans, seats and covers, flushing cisterns and similar sanitary ware, of plastic.

Baths, shower-baths, wash-basins, bidets, lavatory pans, seats and covers, flushing cisterns and similar sanitary ware, of plastics:

Runners and other steel pouring scrap (normal or bottom-poured), including funnels and gates, waste from delivery pipes in bottom pouring, etc., and also reject and defective ingots not included in production.

DURING FILTRATION , COVER THE FUNNEL WITH A WATCH GLASS.

A PLASTIC FUNNEL WITH AN INTERNAL DIAMETER OF NOT LESS THAN 12 CM ,

Allow to stand for 20 minutes, then strain through a folded filter or a Buechner funnel.

Boil the solution to remove the air and introduce 100 ml of wine through the dropping funnel.
