ph meter with the result being a final ph of 1 9 in all three samples although this invention has been disclosed and described with reference to particular embodiments its principles are susceptible to other applications which will be apparent to persons skilled in the art for example a kit could be devised with the salt solution in the syringe which would be connected to the ion exchange filter with the use of a rupturable membrane located between the syringe and filter the acid or base would be generated by applying pressure to the plunger such a kit could be packaged in a plastic bubble pack for immediate use in addition to a manufactured item in a bubble pack the device could be reusable by using chemicals the syringe would be filled in the laboratory with the required salt solution a valve on the syringe would be used to hold the salt solution in the syringe the syringe could be refilled and used many times the ion exchange resin filter could be regenerated in the lab with either acid or base the ion exchange resin filter could be used many times among other advantages the invention affords a safer operation over working with concentrated acid or base in the field in kit form the invention can be easily shipped to various locations without the inconvenience of packaging.
