Freezing Tube Box
A freezing tube box, commonly referred to as a cryobox, is a specialized container designed for the safe and organized storage of cryovials – small tubes used to hold biological samples at extremely low temperatures.
Material
Cryoboxes are predominantly constructed from polypropylene, a robust plastic chosen for its resistance to low-temperature fracture, chemical inertness, and autoclavability. Some specialized boxes utilize polycarbonate for increased durability or conductivity. The internal dividers are typically made of the same material.
Purpose
The primary purpose of a cryobox is to maintain the integrity of biological samples during long-term storage in freezers, typically at -80°C or in liquid nitrogen (-196°C). They protect samples from contamination, physical damage, and temperature fluctuations. Organization is a key function, allowing for efficient retrieval and tracking of valuable specimens.
Function
- Temperature Insulation: Provides a degree of thermal insulation to minimize temperature variations during handling and storage.
- Sample Protection: Shields vials from breakage and contamination.
- Organization: Features a grid-like structure with numbered or lettered slots to facilitate sample identification and location.
- Stackability: Designed to be stacked securely in standard freezer boxes or racks, maximizing storage space.
- Compatibility: Accommodates various cryovial sizes.
Usage Scenarios
- Cell Culture: Storing frozen cell stocks.
- Biobanking: Preserving biological samples (e.g., blood, tissue, DNA) for research and clinical applications.
- Pharmaceutical Research: Maintaining drug candidates and biological reagents.
- Genomics and Proteomics: Storing DNA, RNA, proteins, and other biomolecules.
- Fertility Clinics: Cryopreservation of sperm, eggs, and embryos.
- Veterinary Medicine: Storing animal biological samples.
Common Types
- 96-Well Boxes: The most common type, accommodating 96 cryovials (8x12 grid).
- 81-Well Boxes: Offers a slightly different grid configuration.
- 24-Well Boxes: Smaller boxes for limited sample collections.
- 50-Well Boxes: Another less common size.
- Color-Coded Boxes: Available in various colors to aid in sample identification and workflow management.
- Numbered/Lettered Boxes: Features numbered or lettered slots for easy sample tracking.
- Electronic Cryoboxes: Incorporate barcode readers or RFID technology for automated sample tracking and inventory management.
- Boxes with Dividers: Some boxes have adjustable dividers to accommodate different cryovial sizes or to create custom storage configurations.
- Liquid Nitrogen Safe Boxes: Specifically designed for immersion in liquid nitrogen, offering enhanced durability and resistance to extreme cold.
The declared goods are described as a “freezing tube box”. This suggests a container specifically designed for storing items in a frozen state. The material composition and specific application will determine the appropriate HS code.
Here are the relevant HS codes found within the provided reference material:
-
8418500040: Refrigerators, freezers and other refrigerating or freezing equipment, electric or other; heat pumps, other than the air conditioning machines of heading 8415; parts thereof: Other furniture (chests, cabinets, display counters, show-cases and the like) for storage and display, incorporating refrigerating or freezing equipment Freezing. This code covers furniture incorporating refrigerating or freezing equipment. If the box is a complete unit with its own refrigeration system, this is a potential match.
