About Tianjin Tuozhiming Experimental Instrument Tech Co., Ltd. - Laboratory Equipments & Instruments Supplier in China

Tianjin Tuozhiming Experimental Instrument Tech Co., Ltd. operates out of China and currently lists fifteen active laboratory heating products. The catalogue spans hot air ovens, muffle furnaces, vacuum ovens, several electric hot plates and digestion systems, all classified under the broader Laboratory Equipments & Instruments category. Each item is described with its functional purpose, such as temperature‑controlled drying or high‑temperature sintering, and the only HS‑code explicitly provided is 8419.89 for an Intelligent Electric Hot Plate with a stainless‑steel 304 plate surface and steel housing.

The supplier’s product set includes a Laboratory Hot Air Oven, Laboratory Muffle Furnace, Laboratory Vacuum Oven, Laboratory Voltage‑Adjustable Electric Hot Plate, Laboratory Silicon Carbide Hot Plate, Laboratory Digestion & Acid Steaming Block, Electric Hot Digestion & Acid Removal System, and several variants of electric hot plates. The HS‑code family 8419 (other machinery) is typical for these electrically heated laboratory devices. Materials are noted as stainless‑steel 304 for plate surfaces and steel housings, which aligns with common corrosion‑resistant requirements in laboratory environments.

Product Range and Specialties of Tianjin Tuozhiming Experimental Instrument Tech Co., Ltd.

The catalogue focuses on electrically heated laboratory appliances used for drying, calcining, digestion and controlled atmosphere processing. Typical laboratory ovens are offered in temperature ranges from ambient up to 300 °C, with temperature uniformity of ±2 °C and door insulation meeting ASTM E1137. Muffle furnaces often reach 1100 °C and feature refractory linings, while vacuum ovens are designed for pressures down to 10 Pa and moisture contents below 0.1 %. Electric hot plates commonly provide surface temperatures from 50 °C to 300 °C, with PID digital controllers for precise set‑point regulation. Materials such as stainless‑steel 304 and silicon carbide are standard for corrosion resistance and high thermal conductivity respectively.

Industry practice for laboratory heating equipment includes compliance with IEC 60335‑2‑13 for safety, and many buyers request CE marking or UL certification for equipment sold in Europe or North America. Temperature calibration certificates traceable to NIST or equivalent labs are also typical, as are material safety data sheets (MSDS) for any consumable parts.

Trade and Export Information - Tianjin Tuozhiming Experimental Instrument Tech Co., Ltd.

China is a major exporter of laboratory heating instruments, with shipments commonly directed to research institutions, pharmaceutical manufacturers and university laboratories across Europe, North America and Southeast Asia. The HS‑code 8419 series covers most of the listed items, and customs authorities often require a commercial invoice, packing list and, where applicable, CE Declaration of Conformity. Buyers usually request pre‑shipment inspection reports prepared by agencies such as SGS or Bureau Veritas to verify compliance with safety and performance standards. Packaging for ovens and furnaces typically involves wooden crates with internal cushioning, while hot plates are shipped in reinforced cardboard boxes with metal inserts to protect the stainless‑steel surfaces during transit.

Sourcing from Tianjin Tuozhiming Experimental Instrument Tech Co., Ltd. - Buyer Guidance

When sourcing these laboratory heating devices, buyers should request the following documentation: CE or UL certificates (if required for the destination market), IEC safety test reports, temperature calibration certificates, and material certification for the stainless‑steel 304 components. Samples or demo units are advisable for high‑value items such as muffle furnaces to verify temperature uniformity and control accuracy before bulk ordering. Verify the supplier’s ability to provide PID controller firmware specifications and replaceable heating elements, as these affect long‑term maintenance. Typical minimum order quantities range from a single unit for specialized ovens to batches of ten for standard hot plates, with lead times of 30‑45 days from order confirmation, subject to factory scheduling and export clearance.
