In the field of specimen collection and preservation, the pocket specimen bag plays an irreplaceable role with its unique design and practical functions. With the characteristics of compact and portable, it can meet the needs of proper storage of small specimens in different scenes.

First, structural design

The overall structure of the pocket specimen bag is compact and delicate. Its shape is mostly rectangular or square, the size is usually between a few centimeters and ten centimeters, and it can be easily put into a pocket or small storage box. The bag mouth generally adopts a convenient sealing method, the common self-adhesive sealing and zipper sealing. Self-adhesive sealing operation is simple, just gently press to seal, save time; The zipper seal has better sealing, can effectively prevent the specimen from falling or foreign impurities entering, and can be opened and closed multiple times, convenient access to the specimen at any time. 

Second, material characteristics

In the selection of materials, the pocket specimen bag pays attention to flexibility, transparency and durability. High quality plastic film is used, such as polyethylene (PE) or polypropylene (PP) material. These materials have good flexibility, not easy to break, can adapt to a variety of bending and folding, easy to carry and use. At the same time, they have a high transparency, users do not need to open the bag, can clearly observe the shape, color and other characteristics of the specimen, convenient for preliminary identification and recording. 

Third,functional advantages

1.Strong portability: Its small size and light weight make it an ideal choice for field collection, classroom teaching and other activities. When researchers or students go out, they can carry multiple pocket specimen bags with them to collect small specimens at any time, such as insects, plant seeds, small ores, etc., which is convenient and fast.

2. Protection of specimens: Good sealing performance and material characteristics can effectively protect specimens from the influence of the external environment and prevent specimens from being damaged, contaminated or deteriorated. The integrity of the specimen is ensured even during bumpy transportation.

3. Convenient classification and management: The compartment design and clear visibility in the bag make it convenient for users to classify and store and manage different types of specimens, which is easy to quickly find the required specimens and improve work efficiency.

Fouth, application field

1.Research field: In biology, geology and other scientific research work, pocket-sized specimen bags are often used to collect and preserve small samples to facilitate subsequent research and analysis.

2.Education and teaching: In the school's natural science curriculum, teachers and students can use pocket specimen bags to collect and display specimens, enhance the intuitiveness and interest of teaching, and help students learn and understand knowledge better.

3.Collecting hobbies: For collectors of insects, plants and other specimens, the pocket specimen bag is an essential tool for organizing and preserving the collection, helping to keep the collection intact, and convenient display and communication.

With its unique structure, material and significant functional advantages, the pocket specimen bag plays an important role in many fields, providing an efficient and practical solution for the collection, preservation and management of specimens.
