1 Procurement management: scientific planning from demand to order
Procurement is the first checkpoint in consumables management. It is recommended that the laboratory establish a three-level approval system: the user submits an application, the project leader reviews the necessity, and the procurement specialist compares the inventory and places the order. A gene sequencing center we serve has shortened the procurement approval time by 40% through this process. The focus should be on establishing a list of qualified suppliers, regularly evaluating the supply quality, price and delivery time, and it is recommended to retain 2-3 backup suppliers.

2 Intelligent warehousing: the first checkpoint of quality
After the consumables arrive, they must be strictly inspected. In addition to checking the product name, specifications, and quantity, the packaging integrity, expiration date, and quality inspection report must also be checked. A third-party testing laboratory once ignored the acceptance link, resulting in a whole batch of contaminated culture dishes being put into use, causing significant losses. It is recommended to configure a barcode scanner to enter the acceptance information into the management system in real time and automatically generate an electronic ledger.

3 Scientific storage: environmental control is the key
The storage requirements of different consumables vary greatly. We recommend that laboratories be divided into clear functional areas: normal temperature drying area, 4℃ refrigeration area, -20℃ freezing area, and independent hazardous chemical storage cabinets. It is particularly important to note that strong acids and alkalis must be stored in anti-corrosion cabinets and equipped with secondary leak-proof trays. A university laboratory stored nitric acid in an ordinary cabinet, causing the cabinet to corrode and collapse.

4 Collection management: Establish a traceability mechanism
Implement the principle of “whoever collects, whoever is responsible”, and it is recommended to use an electronic collection system to record information such as the collector, purpose, and amount. For high-value consumables, hierarchical approval authority can be set. The R&D center of a pharmaceutical company successfully reduced the waste rate of high-value consumables by 25% through a facial recognition collection system. At the same time, a regular inventory system should be established, and it is recommended to conduct a comprehensive inventory once a month.

5 Usage monitoring: Eliminate hidden waste
Many laboratories only focus on procurement but ignore the management of the use link. It is recommended to set up consumable collection points in key experimental areas and equip them with quantitative collection tools. An environmental testing agency we cooperated with reduced the monthly consumption of pipette tips by 30% by installing a pipette management system. At the same time, a consumables recycling mechanism should be established to professionally clean and disinfect reusable consumables.

6 Waste disposal: Compliance is the bottom line
Laboratory waste must be collected and processed in accordance with the “National List of Hazardous Wastes”. Sharps should be placed in special puncture-resistant containers, and organic waste liquids should be stored in leak-proof bottles and labeled with standard labels. The laboratory department of a hospital was fined 100,000 yuan for illegally handling medical waste. It is recommended to sign a long-term cooperation agreement with a qualified processing unit.

7 Continuous improvement: data-driven optimization
Regularly analyze consumables usage data and establish key performance indicators: inventory turnover rate, loss rate, procurement timeliness rate, etc. The intelligent management system we developed can automatically generate these analysis reports to help laboratories find improvement opportunities. After application in a national key laboratory, annual consumables expenditure was saved by 18%.
