Dear List Members, My laboratory had many reagents that were very old prepared reagent solutions and/or solvent mixtures, an expiration date (shelf life.
Have a discussion with your lab mates to determine which commonly used reagents should be kept within arm’s reach on the lab bench and which rarely used reagents can be stored away. You can also reduce clutter by creating a schedule for going through your reagents and removing expired and obsolete reagents from your storage space. Establish a consistent labeling system that all lab members use to label aliquots and shared solutions.
Don’t forget to also label shelves and cupboards, which can remind people of where items belong and help keep storage areas organized. Be sure to create clear labels using alcohol-resistant markers.

If the purchased laboratory reagent or solution includes a manufacturer’s suggested “use by” or expiry date, that date should be followed.
Establishment of expiry dating for chemicals, reagents, solutions, and solvents? For purchased laboratory reagents and solutions without a “use by” or expiry date, FDA would expect that an assessment be conducted literature review may be acceptable of that specific chemical’s or chemical family’s stability and that an appropriate “use by” or expiry date be determined. For in-house prepared solutions, such as mobile phases or other non-quantitative solutions, FDA would expect that an assessment be conducted again, literature review may be acceptable to determine an appropriate expiry period.
As mentioned in Guidance for Industry: Q2B Validation of Analytical Procedures: Methodology, the stability of analytical solutions is a typical method variation that should be evaluated during robustness testing during method validation. Method validation is a CGMP requirement at The determined “use by” or expiry dates should be documented within a procedure and followed.
Procedures for any in-house prepared laboratory solution should include the determined stability timeframe, and should instruct that these solutions be labeled with the appropriately determined “use by” or expiration date upon preparation and discarded upon expiration. These principles would also apply to API manufacturing and testing sites. More detail click or tap here. Post a comment.
Expiry date vs. Best Before Date – Reagents
But to maintain the original high degree of purity certain procedures should be observed with regard to storage and handling. For example, impurities can form due to thermal or photolytic decomposition as well as through formation of free radicals. Adverse reactions with atmospheric oxygen can produce dangerous peroxides and dryness can be degraded by contamination with atmospheric moisture.
Effects of this kind differ from product to product and can be more noticeable over a period of time, especially when combining the sensitivity of modern analytical instrumentation with the very high purity of ROMIL laboratory products. At ROMIL we minimise these problems by manufacturing and filling under an inert atmosphere of dry nitrogen.
This allows you to not only track the expiration date, but automatically Lastly, some closed loop systems enable the lab to assign reagent.
This decision is made based on the stability of the solution, its intended use and storage conditions. If this information is not stated in the text in a USP monograph for the particular volumetric solution, then it is up to your lab to define this frequency. You need to have experimental data to support your decision. Do not assume arbitrary frequencies. If this information is not stated in the text in a USP monograph for the particular solution, buffer, etc.
In some cases you can also find information about alternative columns. Yes, volumetric solutions should be standardized before use and re-standardized periodically. The frequency of re-standardization should be defined based on the stability of the solution, its intended use, and frequency of use. Yes, you can use any other standardization procedure as far as it gives at least the same degree of accuracy as the method described in USP.
FAQs: Reagents. How often should volumetric solutions be re-standardized? How do I establish expiry dates for solutions, buffers, etc.?

How to Store Your Reagents, so They ‘Do Exactly What It Says on the Tin’
Quality control samples are special specimens inserted into the testing process and treated as if they were patient samples by being exposed to the same operating conditions. The purpose of including quality control samples in analytical runs is to evaluate the reliability of a method by assaying a stable material that resembles patient samples. Quality control is a measure of precision or how well the measurement system reproduces the same result over time and under varying operating conditions.
Pathologists need to be involved in development of quality control protocols, the selection of quality control materials, long term review of quality control data, and decisions about repeating patient samples after large runs are rejected.
While running out of reagents happens to the best of us, there are steps you can system that all lab members use to label aliquots and shared solutions. Label the new containers with the contents, the date it was aliquoted, and expiry date.
If the manufacturer suggests an expiry date, that date should be followed. The FDA expects an assessment to be performed for purchased laboratory reagents without expiry date indicated by the manufacturer. For example, literature review of that specific chemical’s or chemical family’s stability may be acceptable to determine an appropriate “use by” or expiry date.
For in-house prepared solutions like as mobile phases or other non-quantitative solutions , the FDA expects an assessment to be carried out, too. However, the FDA requires formal stability studies to be performed to determine an appropriate expiry for in-house prepared solutions used for quantitative analysis in assay or impurity testing. According to ICH Q2B, stability of analytical solutions is a typical method variation that should be assessed during “Robustness testings” during validation of an analytical method.
Expiry Dating for Reagents and Solutions in Laboratories: What are FDA’s Expectations?
Thirty-five chemical solutions, acids, bases, complexing, argentometric, reducing, oxidising, salts and eluent mixtures, were studied continuously over a 7. Exceptions were made for potassium permanganate 0. The eight chemical solutions presenting expiration dating higher than 6 months were hydrochloric acid 0. The present data is a suitable guideline for the date of several chemical solutions routinely used in the analytical laboratories. This is a preview of subscription content, log in to check access.

Need Help? Barcodes store information. Usually, that information is related to the identification of a product, but sometimes it can include additional information. The catch here is that barcodes can only store a very limited amount of information and since that information is printed directly on the label it remains static.
This is where RFID comes in handy, with much larger data storage capacities than barcodes, RFID can store a lot more information—and that information can be updated. By including a writing module on the analyzer device itself, you can write an incrementing variable to the tag and use the variable in the user interface UI to display the amount of useful life or the number of tests remaining.
For example, if one reagent pack allows for tests, that variable can be written into the tag. From there, each time the tagged pack is scanned by the analyzer device the number of remaining uses will drop by one. Once the remaining uses on the pack reaches zero the user will be notified by the UI on the analyzer device that the pack is no longer useable. But what if a pack expires before it reaches the maximum allowed amount of tests? If in addition to the number of uses, you encode and track expiration dates, you can also set up your system to notify users when a pack is no longer suitable for use.
Additionally, you can add a color coding system to the interface that allows users to view remaining life visually. Both of these life tracking systems can simplify inventory tracking as well.
Determination of the expiration date of chemical solutions
We’ve just had an ISO audit and one of the things that this brought up was that to work to GLP we need to have expiry dates on all our reagents and chemicals. This was rasied at a recent lab meeting and led to a shouting match. One person now has in very big bold letters written on all her bottles. Another person was told exactly were she could stick her plan to throw out all bottles without sensible dates and people were generally confused and wanted advice It has fallen to me to come up with a sensible plan to which everyone can agree yeah right!
I’ve kinda settled on a one year review date at which point reagents are reassessed and if we have any reason to suspect problems they are binned but if not then extend the expiry date for another year.
