Embodiment Construction

[0044] The drawings are schematic only and simplified for clarity. The same reference numerals are used throughout to designate the same or corresponding parts.

[0045] figure 1 A flexible tube that can be used in a system according to the invention is shown; the tube has an outer diameter 102 , an inner diameter 101 and a tube length 103 . The tube can be made of a flexible material such as optical grade silicone.

[0046] figure 2 The flexible tube 100 is shown inserted into a leveling element 200 comprising a first leveling element 201 and a second leveling element 202 . The two leveling elements are made of transparent material, such as glass. After the flexible tube 100 is inserted into the leveling element 200, the two leveling elements 201 and 202 are pressed together to flatten the flexible tube 100. The flattening of the tube 100 changes the shape of the tube 100 from a circle to a quasi-ellipse with two parallel planar surfaces. A measurement volume 210 compr...

Abstract

The present invention relates to a system for holding a fluid sample, comprising: a transparent flexible tube for holding said fluid sample; a tube holder for fixing said tube; a first leveling element; a second leveling element, wherein said first leveling element and said second leveling element are movable relative to each other thereby causing said transparent flexible tube to change from a first state to a second state, said tube in said second state At least a first cross-sectional dimension is smaller than the first cross-sectional dimension in said first state.

Description

technical field [0001] The invention relates to a flexible sample container for measurements concerning fluid samples. The system is suitable for measuring large and small sample fluids, such as samples consisting of a few microliters. Background technique [0002] In US 3,814,522 Clark and Wells disclose a tube and method of using the tube in the analysis of a urine sample. The tube is made of glass, plastic or other inflexible transparent material and includes a rounded upper end that presents two substantially parallel surfaces and a flat lower end. The lower end is suitable for use in a microscope to examine the flat portion for sediment. The tube is suitable for use with a centrifuge that concentrates the sediment of the flat portion. [0003] The tube shown provides an easy way to place the sample into the sample holder for insertion into the microscope for examination of the sample. However, the tubes shown need to be filled with a pipette or similar, and after ce...
