About Xinxiang Pan Chao Instrument Co., Ltd. - Cryogenic Storage Tank Supplier in China

Xinxiang Pan Chao Instrument Co., Ltd. is a China-based supplier operating from Xinxiang, Henan Province, with 11 active product listings concentrated in a single category: cryogenic liquid nitrogen (LN2) storage tanks. The catalogue covers aluminium dewars in capacities spanning 2 L through 100 L, addressing laboratory, livestock artificial-insemination, and biomedical cold-chain storage needs. All 11 SKUs fall under the cryogenic vessel family, and the supplier's origin in Xinxiang places it within one of China's established clusters for laboratory and cryogenic equipment manufacturing, a region known for cold-chain and biomedical instrumentation output to global markets.

The product mix is weighted toward two application areas: bench-top laboratory storage (3 L, 6 L, 10 L, 15 L units) and larger-capacity storage and transport tanks (20 L, 30 L, 35 L, 50 L, 80 L, 100 L units) used in veterinary reproductive technology, biobanking, and cryopreservation logistics. Static evaporation rates, neck diameters, and working pressure ratings are the primary technical parameters that differentiate the SKUs, and buyers in this category typically evaluate units by their LN2 holding time (days), weight when empty, and compatibility with standard canister/rack systems. The supplier's product line is consistent with the typical Chinese export profile for cryogenic vessels, which are widely shipped to livestock genetics programmes, IVF clinics, and research laboratories across Asia, the Middle East, Africa, and Latin America.

Product Range and Specialties of Xinxiang Pan Chao Instrument Co., Ltd.

The catalogue consists entirely of vacuum-insulated cryogenic LN2 containers, with model designations including the YDS series (YDS-6, YDS-35) and unbranded variants at 2 L, 3 L, 10 L, 15 L, 20 L, 30 L, 50 L, 80 L, and 100 L capacities. Industry-standard cryogenic dewar specifications in this class typically include an inner vessel of aluminium alloy 6061 or equivalent, an outer shell of rolled steel or stainless steel, multi-layer super-insulation (MLI) with vacuum between the walls, and a working pressure rating of 0.05 MPa to 0.09 MPa for non-pressurised storage models. Static evaporation rates for laboratory-grade 3 L to 35 L tanks commonly range from 0.10 L/day to 0.40 L/day, while 50 L to 100 L transport units typically fall between 0.40 L/day and 0.90 L/day, depending on neck diameter and insulation quality.

For livestock and biomedical applications, buyers should expect canisters in 38 mm, 50 mm, 80 mm, and 125 mm neck diameters to accommodate standard cryovial racks, goblets, and semen straws (0.25 mL and 0.5 mL). Common accessories in this category include locking lids, roller bases for transport tanks, and protective outer casings. The supplier's range aligns with the typical specification tiers seen across Chinese cryogenic equipment exporters, where smaller bench-top units serve IVF clinics and university labs, mid-range 15 L to 35 L tanks serve cattle artificial-insemination centres, and 50 L to 100 L units support cryogenic transport and longer-duration biobank storage.

Trade and Export Information - Xinxiang Pan Chao Instrument Co., Ltd.

Cryogenic vessels for liquid nitrogen fall under HS code 7613.00 (aluminium containers for compressed or liquefied gas) for aluminium-bodied dewars and HS code 7311.00 (containers for compressed or liquefied gas of iron or steel) for steel-shelled transport tanks, with the exact classification depending on the dominant shell material of each unit. Chinese exporters of cryogenic LN2 tanks typically ship to livestock breeding programmes in South America (notably Brazil and Argentina), dairy and beef genetics operations in the Middle East and Central Asia, IVF and stem-cell research laboratories across Southeast Asia, and biobanking facilities in Africa and Eastern Europe. The category is heavily regulated under pressure-vessel codes, and buyers in the EU, Australia, and North America generally require CE marking under the Pressure Equipment Directive (PED 2014/68/EU), ASME BPVC Section VIII for North American buyers, and ISO 21010 for the cryogenic vessels category.

Standard export packaging for LN2 tanks involves wooden crates with internal foam bracing, and shipments are typically arranged on pallets with 20 ft and 40 ft container loadings depending on tank size. Incoterms commonly used in this trade segment are FOB, CFR, and CIF, with sea freight being the dominant mode given the non-hazardous nature of the empty vessels (LN2 is loaded at destination). Origin documentation for Chinese cryogenic equipment exports usually includes a Certificate of Origin (Form A or Form E for ASEAN/GSP destinations), commercial invoice, packing list, and a factory test report covering hydrostatic pressure testing, vacuum integrity (helium mass-spectrometer leak test), and static evaporation rate verification. Buyers should note that LN2 tanks are classified as pressure-equipment-related goods, so customs clearance in destination markets may require conformity-assessment certificates beyond standard commercial documents.

Sourcing from Xinxiang Pan Chao Instrument Co., Ltd. - Buyer Guidance

Buyers sourcing cryogenic LN2 tanks from this supplier should request a current factory test report for each model, specifically covering static evaporation rate (L/day), working pressure (MPa), hydrostatic test pressure, and vacuum retention. For livestock and biomedical applications, confirm the neck diameter compatibility with the intended cryovial racks or semen straw goblets before ordering, as 38 mm, 50 mm, and 125 mm neck configurations are not interchangeable. Buyers in regulated markets (EU, UK, Australia, Canada) should specifically request CE documentation under PED 2014/68/EU or equivalent pressure-equipment conformity assessment, while buyers in the United States should verify ASME BPVC compliance. For semen and embryo storage applications, ISO 9001 quality management certification at the manufacturing level is a common baseline requirement, and veterinary buyers may also request documentation supporting IETS (International Embryo Technology Society) guidelines for cryogenic equipment used in reproductive technology. Before placing a volume order, requesting a pre-shipment sample unit for independent verification of evaporation rate and vacuum integrity is standard practice in this category, and lead times of 15 to 30 days for stock models and 30 to 60 days for customised configurations are typical for Chinese cryogenic equipment manufacturers.
