PTFE digestion tube, used for sample pretreatment, resistant to HNO3
The PTFE digestion tube offered by Nanjing Binzhenghong Instrument Co., Ltd is manufactured from virgin PTFE, providing exceptional resistance to concentrated nitric acid. It is designed for sample pretreatment in laboratory workflows such as microwave digestion, ICP analysis and atomic absorption spectrometry. The tube features a non‑stick surface that facilitates cleaning and reuse, improving laboratory efficiency. Its construction complies with ISO and SGS standards, ensuring consistent quality for analytical applications.
In the laboratory supply market, PTFE tubes are commonly supplied with a temperature tolerance up to 260 °C, which is typical for virgin PTFE material. Standard dimensions include a length of 150 mm and an inner diameter of 5 mm, although variations exist across manufacturers. The tubes are typically packaged in bulk with each unit sealed in a protective polybag to prevent contamination. Users value the precise volume handling capability that supports accurate trace metal detection.
Primary users include environmental testing laboratories, pharmaceutical quality‑assurance units and geological analysis facilities that require robust chemical resistance. Trade terms generally allow flexible minimum order quantities and can be negotiated under FOB or CIF incoterms, with payment options such as L/C or T/T. Prospective buyers should verify the supplier’s certification documents and request a sample to confirm performance before placing a bulk order.

Sourcing PTFE digestion tube, used for sample pretreatment, resistant to HNO3 from Nanjing Binzhenghong Instrument Co., Ltd - China Import Guide
Before placing an order, importers should request the supplier’s ISO and SGS certificates to confirm the stated chemical resistance and temperature performance. It is advisable to obtain a material safety data sheet and, if possible, a sample tube for laboratory testing. Verifying the exact dimensions and tolerance data will ensure compatibility with existing digestion equipment and prevent downstream issues.
The trade terms listed allow negotiation under FOB or CIF incoterms, and payment can be arranged via L/C or T/T. Importers need to confirm the expected lead time, as the supplier’s response metrics are not disclosed, and clarify any freight forwarding arrangements. Shipping destinations, port handling charges and customs documentation requirements should be discussed in advance to avoid delays.
During the pre‑shipment phase, buyers should arrange third‑party inspection to verify the tube’s material integrity and dimensional conformity. Requesting a full test report that includes chemical resistance, temperature tolerance and surface finish will provide additional assurance. Import documentation typically includes a commercial invoice, packing list, certificate of origin and the supplier’s compliance certificates, all of which should be reviewed before cargo release.
