PCT No. PCT/NO87/00043 Sec. 371 Date Feb. 8, 1988 Sec. 102(e) Date Feb. 8, 1988 PCT Filed Jun. 1, 1987 PCT Pub. No. WO87/07585 PCT Pub. Date Dec. 17, 1987.A bottle or container includes two semispherical parts which are fixed to each other and are equipped with valves at each end. The bottle can have an inner metal lining and a semispherical membrane which presses against the one part of the lining and has a flange welded between the two parts of the lining. The metal lining with membrane and end pieces forms a replaceable unit. By sampling, the bottle first is filled with a counter pressure medium, for example water, until the membrane lies tightly against one half of the bottle. The bottle is then filled with the fluid/gas-sample such that the membrane reverses as water is pressed out and the sample flows in. The membrane will reverse until it presses against the opposite hemisphere, and the bottle thereby is filled with fluid/gas sample.
