Hollow rectangular capillary tubing made of Borosilicate glass:
50 mm long 0.02 mm ID x 0.20 mm width, 0.02 mm wall, 30 PCS/vial
Capillary tubing provides the fastest, cleanest, most convenient method for collecting, viewing, and storing liquid samples. Capillary action instantly collects the sample and retains a precision optical path length while viewing at any angle, minimizing reflections and eliminating the need of a cover glass. Samples can be permanently retained for reference by fusing or cementing the open ends. Tolerances of +/-10% of inner dimensions are standard, but custom sizes with tighter tolerances are also available.

Rectangle Cells are made from high quality, precision drawn
Borosilicate and Clear Fused Quartz tubing. A flat bottom is fused, not
cemented, to these clear glass containers and the open end is fire polished.
These cells have application where high purity work and transmission of UV are
required. Standard stock product have wall tolerances of +/-20%, but custom
cells can be fabricated with tighter wall and inner dimension (ID) tolerances
to a customer's specification
