Gastec gas detector tube NO.12LL
The Gastec gas detector tube NO.12LL supplied by Henan Greeenland Tech Industrial Co. Ltd is a thin‑walled glass tube designed for on‑site detection of hydrogen cyanide (HCN). The tube is identified by the code 12LL and carries a calibrated colour‑change scale that reads concentrations directly. Its specified measuring range is 0.2 to 10 ppm and the manufacturer states a shelf life of two years from the date of production. Each tube is hermetically sealed and bears a unique quality‑control number.
The detection reagent is a silica‑gel/alumina matrix that reacts selectively with HCN, a standard configuration for Gastec short‑term tubes. Production lots are tested and calibrated independently to maintain precision, a practice typical for laboratory‑grade detector tubes. The supplier notes ISO, SGS and SEI certifications, although these claims have not been independently verified and should be confirmed before purchase. The tubes are packed in standard cardboard boxes, commonly containing fifty units per box.
The tubes are used by environmental monitoring firms, industrial safety teams and emergency responders who need rapid field measurements of cyanide vapour. Henan Greeenland Tech reports that stocked items can be dispatched within three working days, and that shipment speed is about ten percent faster than many Chinese competitors. Minimum order quantities are not listed, so buyers should request the exact MOQ and preferred Incoterms from the supplier. Payment terms and detailed pricing are also to be clarified directly with the supplier.

Sourcing Gastec gas detector tube NO.12LL from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
The first step before placing an order with Henan Greeenland Tech is to verify the authenticity of the tube specifications and any claimed certifications. Request a copy of the ISO, SGS or SEI certificates and compare the tube’s quality‑control number with the batch documentation supplied. Confirm the production date to ensure the two‑year shelf life remains adequate for your project timeline.
Logistics for this product are straightforward because the supplier keeps ordinary detector tubes in stock and can ship within three working days. However, the exact Incoterm, freight forwarder and freight cost are not disclosed in the listing, so you should negotiate these details directly. Ask the supplier to confirm lead time for larger volumes and whether they can accommodate containerised shipments to your preferred port.
Upon arrival, inspect each tube for intact sealing, clear calibration markings and the printed quality‑control number. Retain a sample batch for a laboratory verification of the colour‑change response against a known HCN standard. Request a test report that documents the calibration verification performed on the shipment, which will support compliance with your internal safety protocols.
