Quality Assurance
Value Products, Inc. (VPI) is pleased to offer its customers a laboratory skilled in both Quality Assurance and Research & Development. The laboratory spends considerable time developing new formulations, and improved versions of existing formulations and is available to consult with customers in the development of custom formulations.
VPI uses 100% sampling for quality assurance. Once new formulations are developed, or existing formulations modified, product specifications are established for all critical parameters, such as specific gravity, pH and alkalinity. All production batches are checked for conformance to these specifications and results are recorded. Only batches that meet all quality control standards are released for packaging. Finally, a sample is retained from all approved batches for three months.
