Abstract

Det er beskrevet en kapillar inokulator (12) for Inokulering av et mangfold av forsøkspunkter (64) ved små nøyaktige volumer av podestoff. Inokulatorene (12) som anvendes l anordningen, omfatter en kanalformet bærer (18) og en eller flere rader av kapillarer (26) som strekker seg gjennom denne. Kaplllarene (26) strekker seg gjennom en eller flere rader av pro- jeksjoner (28) som utgjør den nedre delen av bæreren (18). De fylles fullstendig ved kaplllarvlrknlng og podestoffet holdes l disse ved vedheftskraft og overflatespenning. En forsøksanordning kan anvendes l forbindelse med kapillar inokulatoren (12) og omfatter diskrete testpunkter (64) som er Innrettet med endene til de respektive projeksjonene (28). Hvert av forsøkspunktene (64) kan Inneholde et absorberende materiale som for eksempel en celluloseplate. Det kan deponeres et tørt reagens på hver plate, slik at podestoffet kan analyseres ved forsøksutstyr eller ved visuell observasjon. Det er også frembragt en fremgangsmåte som Inkluderer trinnene ved fylling av kapillarene (26), Innrette kaplllarene (26) med forsøkspunktene (64) i forsøksanordningen og deponere det væskeformige podestoffet på de respektive for- søkspunktene (64) ved vekevirkning eller andre prosedyrer. Det er også beskrevet en fremgangsmåte for frembringelse av et mangfold av diskrete væskeprøver med små nøyaktige volumer fra en mengde væsker som kan ha et ubestemt volum.A capillary inoculator (12) is disclosed for inoculating a plurality of test points (64) at small accurate volumes of graft. The inoculators (12) used in the device comprise a channel-shaped carrier (18) and one or more rows of capillaries (26) extending therethrough. The capillaries (26) extend through one or more rows of projections (28) constituting the lower portion of the carrier (18). They are completely filled by capillary action and the inoculum is held therein by adhesion and surface tension. A test device may be used in conjunction with the capillary inoculator (12) and comprises discrete test points (64) aligned with the ends of the respective projections (28). Each of the test points (64) may contain an absorbent material such as a cellulose plate. A dry reagent can be deposited on each plate so that the inoculum can be analyzed by test equipment or by visual observation. There is also provided a method which includes the steps of filling the capillaries (26), aligning the capillaries (26) with the test points (64) in the test device and depositing the liquid graft at the respective test points (64) by waking or other procedures. There is also disclosed a method for producing a plurality of discrete liquid samples with small accurate volumes from a plurality of liquids which may have an indefinite volume.
