Reagent consumables are one of the commonly used materials in colleges and laboratories, and they are also indispensable items for experimenters. However, whether reagent consumables are purchased, purchased or used, there will be a series of problems before the management and users of reagent consumables. What are the specific problems? Let me give you a brief introduction.
For the purchase of reagents and consumables, because of their information asymmetry, coupled with the fact that the supplier of reagents and consumables has hired salespersons for sales, the prices are inflated after layer by layer of price increases. As a result, the price of buying the same reagent in two laboratories next to the same university/laboratory on the same floor is very different. In addition, most scientific research/testing personnel were unable to identify the supplier`s qualifications, which resulted in the receipt of [fake goods” and [parallel imports”. In the end, they worked hard for more than half a year of experiments, but the results of the experiments were complete because they bought fake reagents. invalid. Falsification of reagent consumables seriously affects scientific research and test results, and it is not uncommon for researchers to spend a lot of time, money, and energy on research that is not effective. Some counterfeiting methods are very concealed. This ELISA kit will also use a certain index product to impersonate other index kits. But compared to the previous approach of VEGF, which is a product package, the “smart” is that the indicators used for replacement are more diversified and concealed, which is hard to prevent.
So how can I find genuine reagents and consumables to avoid being fooled? Here are a few methods:
1. Find the right consumables and reagent suppliers
When purchasing reagent consumables, you must avoid buying fake reagent consumables from the source. So, how to choose the right supplier of reagents and consumables is very important. The selection of suppliers can be based on two points: 1 is to choose more than two big brands and suppliers with good reputation; 2 to establish a sound supply management system. Establish evaluation standards for reagent and consumable suppliers, register the quality of each supply of reagent and consumables, and have a punishment mechanism for violations, such as prohibiting them from participating in bidding and supply during a supply cycle. Choosing more than two suppliers can be used to compare the quality and price of the two parties, so as to provide better and more choices for related personnel in universities/labs.
2. Learn simple identification skills
There are many identification techniques for reagents and consumables. The following is just a brief list of two:
1. Look at the packaging
When we get the reagents and consumables, we should first confirm that the seal has not been torn or there are no other traces of movement. When checking whether there are any moved seals, pay attention to whether the lines of the seal pattern and graphics are connected correctly. If the lines of the patterns and graphics do not match, the packaging has been passive.
2. Look at the discoloration/coating anti-counterfeiting label
The most intuitive way to identify reagent consumables is to change the viewing angle, and you can see that the color-changing anti-counterfeiting label appears in the following two colors. First, scratch off the “coating anti-counterfeiting label” on the package to get the anti-counterfeiting code, and then log on to the corresponding official website to check.
