followWith the development of technology, the use and experimental frequency of hazardous chemicals have also increased sharply; Due to their unique chemical properties, chemicals also have special management requirements for their regulation; Improper management directly affects the safety of laboratory researchers. However, traditional chemical management methods have limited regulatory efforts in the face of the constantly emerging hazardous chemicals, leading to the emergence of intelligent reagent cabinets.

2Classification of intelligent reagent cabinets

In accordance with the requirements of national hazardous chemical management laws and regulations, solve the problem of traditional hazardous chemical management in laboratories being unable toProblems such as 24-hour monitoring, manual paper recording, error prone data transmission, lack of intelligent warning, and difficulty for regulatory authorities to conduct audits; Shanghai Yexuan Information Technology Co., Ltd. has independently developed, produced, and sold RFID intelligent reagent cabinet products and services based on years of RFID industry experience; At present, there are mainly two types of intelligent reagent cabinets on the market: barcode type and RFID type intelligent reagent cabinets.

2.1、Barcode type

1. Return: After returning the reagents, manual scanning is required to know the information of the collected items, as manual operation is required

(1) Forgetting to scan may occur, resulting in incorrect reagent data in the cabinet;

(2) If the reagent is returned to the wrong location (for example, if it was taken out of cabinet door 1 and returned to cabinet door 2), it will also result in incorrect location information of the reagent inside the cabinet; However, some reagents that may cause chemical reactions and cannot be placed together pose safety hazards;

2. Collection: After collecting the reagents, manual scanning is required to know the information of the collected items, as manual operation is required

(1) Forgetting to scan may occur, resulting in incorrect reagent information in the cabinet; The system shows that the reagent is still in the cabinet, but when I went to retrieve it, I found that the bottle of reagent was missing;

(2) Scan the wrong reagent; For example: (I planned to receive a bottle of hydrochloric acid, but mistakenly took it as sulfuric acid. If I forgot to scan the cabinet itself, it would not be recognized, and the subsequent reagent information data would be incorrect.)

3. Weighing: When weighing reagents, manual scanning is required to know the information of the collected items, as manual operation is needed

(1) There may be situations where the reagents are forgotten to be scanned and placed in the cabinet without being scanned; The reagent content information on the system will be incorrect, and the reagent data will be inaccurate;

4. Inventory: During inventory, people need to hold a scanning gun and scan each reagent one by one

(1) Consuming manpower and requiring manual operation;

(2) When there are a large number of reagents, there may be omissions, resulting in incorrect reagent information in the system;

5. Operation log: Without scanning, there will be no operation log, and it is impossible to query the operation log of who received what reagent at what time;

2.2TheRFIDtype

1. Return: When returning, simply place the reagent into the cabinet, and the intelligent cabinet will automatically recognize the information of the returned reagent; (Reagent name, usage amount, etc.)

2. Collection: When collecting, simply close the cabinet door after taking out the reagent, and the smart cabinet will automatically recognize the information of the collected reagent; (Reagent name, current reagent content)

3. Weighing: When weighing, place the reagent on the weighing platform, and the weighing control platform will automatically recognize the reagent information;

(Reagent name, weight) No need to manually scan the reagent barcode;

4. Inventory: RFID type intelligent reagent cabinet, one click system inventory; Search and query for different reagents or dates;

5. Operation log: The system automatically determines which person received which reagents at what time; Real time backend query;

By comparison, it can be seen thatThe RFID reagent cabinet not only improves the convenience of researchers using reagents and the safety of the cabinet in operation, but also achieves intelligent management through RFID technology to ensure the accuracy of hazardous chemical circulation data, which has significantly helped in the management of laboratory hazardous chemical reagent cabinets.

3、Advantages of RFID intelligent reagent cabinet

At present, universities commonly use barcodes or QR codes for management, but these types of labels are easily damaged and difficult to identify, making it difficult to achieve comprehensive supervision.

ButRFID electronic tags are electronic chips that not only have good penetrability, but also have a larger storage capacity for information. They can be read and written repeatedly, and are corrosion-resistant and not easily damaged. Coupled with RFID scanners, they can complete contactless rapid inventory, improve efficiency, and accurately track every step of hazardous chemicals, ensuring safety throughout the entire lifecycle.

1. Automatic identification: RFID, as a chip sensing method, records the collection and return of reagents without manual operation, and automatically produces electronic ledgers.

2. Automatic alarm: If the reagent is taken or placed in the wrong position, the RFID system can automatically alarm and prompt (barcode scanning may cause data loss due to forgetting to scan, resulting in all subsequent data being incorrect).

3. Remote inventory: For external chemical reagents, quick inventory can be conducted through RFID handheld devices, or one click inventory of chemicals in the smart cabinet can be conducted through the management backend.
