    • A method for detecting the presence or absence of microorganisms belonging to the group which consists of bacteria and yeasts in a liquid sample (5) of a biological material. The method comprises placing the liquid sample (5) in a centrifuge tube (6a, 6b) above a gelled system (10) comprising at least (a) a first so-called development phase (1), i.e. a gel comprising a microorganism culture medium and a reagent for inducing a detectable optical measurement change in the presence of microorganisms, said gel being an intimate mixture of water and water-absorbing polymeric particles that have swelled in such a way that, in said intimate mixture, said polymeric particles have (.alpha.) a dry weight concentration of 0.05-0.2 g/ml, and (.beta.) a swollen-state diameter of 90-320 .mu.m, the water in the intimate mixture being at least partially provided by said culture medium; centrifuging; and revealing the presence or absence of microorganisms in said liquid sample (5) at said first phase (1) of the gelled system (10) by means of said reagent inducing a detectable optical measurement change.

    • The device embodying the invention uses a filter element encapsulating me acting like a sphincter, a means enabling an air flow to be generated through the filter element once the filter element has been encapsulated, and a means enabling measurement of at least one parameter relating to the fluid flow through the filter. The encapsulating means comprises a succession of encapsulation modules arranged coaxially end to end and each acting like a sphincter, independently of the others, by means of a control means separate from that of the others. The invention applies notably to the measurement of draw through the filter sticks used in filter-tipped cigarettes.
    • 体现本发明的装置使用像括约肌一样起作用的过滤元件封装装置,一旦过滤器元件被封装就能够通过过滤元件产生空气流的装置,以及能够测量至少一个与 流体流过过滤器。 封装装置包括一系列同轴端对齐地布置的封装模块,并且每一个独立于括约肌,通过与其它手段分开的控制装置独立于其他方式。 本发明特别适用于通过过滤嘴香烟中使用的滤棒的拉伸测量。
