Immobilized pH gradient (IPG) strips are encapsulated in an enclosure that seals the strip (12) from atmospheric exposure and yet contains sufficient volumetric capacity (15) to accommodate the strip in rehydrated form. The enclosure contains a pair of electrode access apertures (21, 22) each of which is spanned by a dialysis membrane to permit electrical contact between external electrodes and the encapsulated IPG strip, and one or more sample application apertures (23) through which lipid sample can be applied to the strip. Each of the apertures is covered by a protective cover or flap (24, 25, 26) that is removable to expose the aperture.
Des bandes de gradient à pH immobilisé (IPG) sont encapsulées dans une enceinte hermétique qui protège la bande (12) contre l'exposition atmosphérique et dont la capacité (15) volumétrique est cependant suffisante pour recevoir la bande sous forme réhydratée. L'enceinte comprend deux trous d'accès d'électrodes (21, 22), chacun recouvert d'une membrane de dialyse permettant un contact électrique entre des électrodes extérieures et la bande IPG encapsulée. L'enceinte contient en outre au moins un trou d'application d'échantillon (23) à travers lequel on peut appliquer l'échantillon liquide sur la bande. Chaque trou est recouvert d'un couvercle ou rabat (24, 25, 26) de protection amovible de façon à présenter le trou.
