Glass tubing or pipets can be easily cut to length by scoring the tubing with a fine file, just a small notch is required, then hold the tubing in each hand, (protected with glove or cloth), thumbs on each side of notch, and with the notch away from your body, snap the tubing at the cut. Pyrex glass is harder to break than softer glass but this technique is standard in labs. Usually the ends of the glass are then fire-polished by melting the cuts in a flame. A low temperature flame works for soft (soda) glass but a higher temperature flame is required for Pyrex glass. A propane torch used for plumbing works. See http://www.nmsu.edu/~safety/programs/lab_safety/l_saf_guide07.htm for additional information about safe use of glass tubing.<br><br>It would be possible to make glass containers for Potable Aqua tablets using glass tubing. Melting the glass at each end could seal these. You are just left with the problem of tablet deterioration once opened. Lab supply houses sell glass ampoules, which are heat sealable containers. These would also work.<br><br>Overall I think the glass vials Barry sells are a superior way to carry smaller packages of the tablets and do not present any problems of tablet quality in storage or after opening during an emergency. Iodine vapors in a kit from leaky packaging could compromise or damage the PSK contents in addition to degrading the effectiveness of the tablets for their intended purpose. <br><br>
