How to clean and maintain it?

Rinse with mild detergent and distilled water. Avoid abrasive tools to protect the silver plating. Ensure it is fully dry before storage to prevent internal condensation.

What safety precautions should I follow?

Avoid sudden temperature changes to prevent cracking. Wear protective gear (gloves, goggles) when handling cryogenic liquids. Do not overfill, leaving space for liquid expansion.

AI-Powered supplier vetting

SummaryXinxiang LN Special Equipment Co., Ltd. is a supplier focused on liquid nitrogen tanks and related cryogenic equipment, with a stated business scope covering medical devices, veterinary equipment, experimental instruments, and import/export activities. It holds ISO 9001 certification and reports quality assurance, raw-material traceability, six to ten quality-control staff, and annual liquid nitrogen tank output of 8,000 pieces. The supplier provides technical advice, equipment-operation and maintenance training, global distribution, and multiple customization options. However, the available information states that it is not a professional technical supplier, has no recent new-product development, does not offer ODM, OEM for popular brands, 3D software design, or SDK services. Overseas service infrastructure is limited, with no overseas showroom, agents, branches, or offline trade-show participation. Financial records are referenced for multiple years, but no assessable financial results are provided.

Supplier typeThe supplier is presented as a cryogenic equipment manufacturer and solution provider, with products centered on liquid nitrogen tanks for laboratory and industrial use. Its registered business scope also includes medical devices, veterinary equipment, experimental instruments, and import/export activities.

CertificationsThe supplier reports ISO 9001 certification, along with quality assurance in its quality-control processes and traceable identification of raw materials. These statements provide explicit evidence of certification and documented quality-control practices.

After-Sales capabilityThe supplier offers technical advice and training on equipment operation and maintenance and states that its logistics network supports delivery worldwide. However, it reports no overseas showroom, agents, branches, or overseas-service countries; complaint handling and corrective-action capabilities are only categorized as “Others,” so the overall service infrastructure is mixed.

R&D capabilityThe supplier states that it is not a professional technical supplier, had no new products during the past year, and does not provide ODM, popular-brand OEM, SDK, or 3D software design services. Although it describes continuous technological innovation and has six to ten years of total R&D-engineer experience, the explicit capability data indicates limited demonstrated innovation services.

Production capacityThe supplier reports annual production of 8,000 liquid nitrogen tanks and describes products serving both laboratory storage and large-scale industrial applications. It also reports six to ten quality-control staff, although finished products are checked by packing staff and only one quality-assurance/quality-control inspector is separately specified, limiting the strength of the production-quality evidence.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization options despite the absence of 3D software design services.

Product Q&A

Q:What is a glass Dewar flask (cold trap)?

It is a specialized double-walled glass container with a vacuum-sealed gap for insulation and silver plating to reflect heat. When used as a cold trap, it pairs with vacuum systems to condense vapors and gases.

Q:What are the main uses of this product?

Main uses include storing cryogenic liquids (liquid nitrogen, helium), acting as a cold trap in vacuum setups to protect pumps, maintaining stable low-temperature environments for lab reactions, and preserving temperature-sensitive samples.

Q:How does the vacuum-insulated and silver-plated design work?

The vacuum gap reduces heat transfer via conduction and convection, while the silver plating reflects radiant heat, effectively minimizing temperature loss or gain.

Q:Can it be used with non-cryogenic materials?

Yes, it is also suitable for insulating room-temperature or moderately cold substances, such as refrigerated reagents, to prevent temperature fluctuations.

Q:Is it compatible with all vacuum systems?

It works with most standard laboratory vacuum systems, but you should confirm that the flask's size and specifications match your system's ports before use.
