The Gastec gas detector tube No.4LK is a disposable glass tube intended for rapid on‑site detection of hydrogen sulphide (H2S). Its calibrated measuring range spans 1 to 40 ppm and the product carries a three‑year shelf life from the date of manufacture. Each tube is marked with a unique quality‑control number and a direct‑reading scale printed on the glass, enabling instant visual assessment. Inside, a silica‑gel/alumina matrix reacts with H2S to produce a distinct colour change.
Standard Gastec short‑term tubes typically measure about 100 mm in length with a 10 mm outer diameter, dimensions that are common across the brand’s product family. The hermetically sealed ends safeguard the reagent against moisture and external contaminants, preserving the tube’s long‑term stability. Production lots are individually calibrated, and the printed scale follows Gastec’s internal standard, a practice widely adopted in the gas‑detection industry. These characteristics make the 4LK tube suitable for routine safety checks where quick H2S screening is essential.
Primary users include oil‑field safety personnel, wastewater‑treatment operators, and industrial hygiene teams that monitor H2S exposure. The supplier notes that items held in stock can be shipped within three working days and claims a 10 % faster dispatch than many domestic competitors. Prospective buyers should confirm the exact minimum order quantity and preferred Incoterm, as these parameters are not disclosed in the public listing. Payment arrangements are negotiable, so direct communication with the supplier is advised to agree on suitable terms.

Sourcing Gastec gas detector tube No.4LK from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Importers should first ask the supplier for up‑to‑date copies of any ISO, SGS or SEI certificates referenced in the product description, as well as the exact production date to verify the three‑year shelf life claim. Clarify the minimum order quantity, packaging format (normally individual glass tubes packed in sealed cardboard) and whether the tubes are stocked or made to order. Ensure that the colour‑change scale is legible and that each tube carries a unique quality‑control number for traceability.
Common shipping arrangements for Chinese glass‑tube products include FOB Zhengzhou or CIF Shanghai; the supplier indicates that stocked tubes can be dispatched within three working days, providing a short lead time. Agree on payment terms such as irrevocable L/C or T/T after receipt of a commercial invoice, and confirm any required export documents like a certificate of origin. Early agreement on the incoterm and freight forwarder preferences helps prevent customs or shipping delays.
For quality control, request a third‑party inspection that checks the colour change, verifies the printed calibration scale and confirms the hermetic seal of each tube. A batch test report documenting the stability of the H2S reagent over time can also be requested. Keeping records of the quality‑control numbers will aid in tracking performance and addressing any future issues.
