Abstract

MECáNICO PARA MISTURAR UMA AMOSTRA FLUIDA COM UMA SOLUçãO DE TRATAMENTO Um dispositivo para a preparação de uma amostra fluida para uso em um dosador de analito fluido, incluindo: (a) uma primeira parte, compreendendo: um canal capilar dimensionado para receber uma amostra fluida no mesmo, um bocal interno em comunicação com o canal capilar, uma câmara de mistura em comunicação com ambos o canal capilar e o bocal interno, e um bocal de distribuição em comunicação com a câmara de mistura; (b) uma câmara de solução de tratamento coberta por uma membraba; e (c) uma segunda parte que é móvel com relação á primeira parte para perfurar a membrana de forma que o conteúdo da câmara de solução de tratamento seja misturado ao conteúdo do canal capilar na câmara de mistura e seja ejetado através do bocal de distribuição quando a segunda parte é movida com relação á primeira parte.
