There are salt crystals around the cap or on the box - is it okay to use the kit?
No. This indicates that the clear buffer solution in the white capped tube has leaked. This is usually
caused by pressure changes in an airplane cargo hold during shipping. The buffer solution should be
approximately ½ inch above the 5 ml line embossed on the tube. If the tube does not contain the proper
amount of buffer solution, hold the kit aside and contact Dexsil for a replacement kit.
