Our VitroTubes™ hollow square tubing is available in a wide variety of path lengths, widths, and wall dimensions. These hollow glass tubes are supplied in convenient plastic vials for easy handling and storage. They provide the fastest, cleanest, and 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. The sample can then be permanently retained for reference by fusing or cementing the open ends. If you need hollow square tubing, VitroTubes™ is the solution for you.

You can choose from our standard product list below or design your own. Choose your selected size, length, tolerances, glass type, and end Finish using our Tubing Template and create your perfect custom tubing today.
