Expiration dating for laboratory reagents and solutions

If labs in a single institution are very serious about saving costs, institutions could implement programs in which nearby or adjoining labs share certain chemicals in order to ensure that materials are efficiently used, while reducing the costs for individual lives.As described in the book “Prudent Practices in the Laboratory: Handling and Management of Chemical Hazards,” a chemical inventory management system can be “centralized in one purchasing office or may be dispersed to varying degrees throughout the institution.” This centralization process enables laboratory personnel to determine if a material is already available in another laboratory and can be utilized, as well as the “minimum quantity that will suffice for current use,” in order to reduce waste as previously discussed.

Instead, laboratories should purchase smaller quantities with more frequent inventory turnovers.Additionally, expired chemicals pose safety and/or regulatory violations, which can be especially damaging for companies that deal in human products or food materials.Indeed, in his article for , Flaherty lists the most common chemical storage practices that are actually violations, which include “storage of expired chemicals, incompatible and reactive chemicals stored alphabetically, oxidizing chemicals mixed with organic lab waste, open containers kept in satellite storage areas between pours, poor recording keeping, unlabeled or poorly labeled secondary containers.” Together, these mistakes can be prevented when proper chemical inventory management protocols are in effect.We have developed one of the most through chemical inventory management systems through our BIOVIA CISPro software, which enables managers and researchers to track and report the use of chemicals and related supplies in multiple facilities and locations.Our software thus supports accurate and real-time chemical inventory data, while also helping to ensure that a laboratory’s practices adhere to safety regulations.This date assigns the time frame during which the batch is expected to remain within established specifications if stored under Sigma-Aldrich’s defined conditions. Expiration Dates on our labels and/or Certificates of Analysis are valid only if the product is stored under Sigma-Aldrich’s defined conditions, and the container has remained unopened with original tamper evident seal still intact.

A number of Sigma-Aldrich products are not included in either of the above programs as there is no indication to conclude they are unstable.Unfortunately, poor chemical inventory management makes such situations more common than they should be, resulting in lost time for the individual and the lab, as well as lost resources.As Richard Flaherty writes for In the video “How Tracking Chemical Inventory Expiration Dates in Real-Time Increases Efficiency and Lowers Costs,” we discuss how easy it is to “[lose] track of chemical containers when their expiration dates are not tracked by a digital chemical inventory system.” Unfortunately, when these chemicals expire, disposal costs are also incurred and given that the material was not used efficiently before it’s disposal, the cumulative loss to the lab is significant.When dating is indicated by month and year only and no specific date is otherwise stated on the label or elsewhere, the product is expected to meet specifications until the last day of the month.The Recommended Retest Date is the end of a period of time during which the batch is expected to remain within established specifications if stored under Sigma-Aldrich’s defined conditions.To determine how BIOVIA CISPro can be used in your company, please visit our website today.
