Import Cryogenic Sample Storage 30 Liter — Buy in Bulk from Supplier in China

Henan Tianzhidao Biological Technology Co., Ltd. in China offers the Tianchi KGSQ Cryogenic sample storage 30 liter dewar, a double‑wall aluminium‑alloy vessel designed for liquid nitrogen preservation. The unit adopts an inner and outer aluminium alloy shell with a vacuum layer that minimises heat ingress. Available models (YDS‑30, YDS‑30‑80, YDS‑30‑125, YDS‑30‑210) share a 31 L internal volume and a 440 mm outer diameter, while the calibre varies from 50 mm to 210 mm and the height is 730 mm. Static liquid nitrogen evaporation capacity ranges from 0.09 kg / day for the 50 mm calibre to 0.50 kg / day for the 210 mm calibre. Aluminium alloy is the standard material for laboratory‑grade cryogenic dewars because of its strength‑to‑weight ratio and resistance to corrosion at - 196 °C. The vacuum‑insulated construction is typical for containers that require low boil‑off rates, matching industry norms for sample preservation. A typical dewar of this class provides a static storage temperature of - 196 °C and can hold up to 31 L of liquid nitrogen without active refilling. The design complies with common safety standards for pressure relief and venting, which are essential for laboratory environments. The product carries a five‑year warranty on the aluminium structure and two years of after‑sales service, with a 30‑day return option if the unit does not meet specifications. Buyers such as biomedical research labs, material‑science facilities and superconducting‑material developers commonly source this tank for long‑term cryopreservation. Prospective importers should confirm the exact model, minimum order quantity and shipping incoterm with the supplier before placing an order.

Henan Tianzhidao Biological Technology Co., Ltd. is located in the High‑Tech Industrial Development Zone of Zhengzhou, Henan Province, China (postal code 450051). The supplier holds a harbour‑level trust tier, though its response rate is currently listed as 0.00, indicating that inquiries may experience delayed replies. The company’s address is recorded as Building 11, 1305, 289 West Third Ring Road, Zhengzhou.

The firm reports more than ten years of production experience in cryogenic equipment, equipped with professional production technology and high‑tech machinery. Its product line includes aluminium‑alloy liquid nitrogen containers, self‑pressurised vessels and stem‑cell cryogenic tanks. The listing states that none of its products are recycled, providing confidence in material integrity. A 30‑day return policy is offered, allowing buyers to return items for any reason within that period.
