Gastec Gas Detector Tube NO.7LA
The Gastec Gas Detector Tube NO.7LA is a colourimetric glass tube designed to detect phosphine (PH3) in air. It measures concentrations from 0.05 ppm up to 9.8 ppm and carries a printed calibration scale for direct on‑site reading. The tube is hermetically sealed and bears a unique quality‑control number on its body, ensuring traceability for each production lot. Its shelf life is stated as two years from the date of manufacture, after which the reagent may lose sensitivity.
The detection reagent is embedded in a silica‑gel/alumina matrix that reacts with phosphine to produce a distinct colour change. Typical Gastec tubes are about 100 mm long and 12 mm in diameter, dimensions that fit standard portable samplers. The glass is thin but robust, allowing easy handling while maintaining optical clarity for colour assessment. Tubes are usually supplied in cardboard boxes containing 25 units, a packaging format that protects the glass during transit.
These tubes are widely used in grain storage facilities, fertilizer plants and environmental monitoring stations where phosphine leaks pose safety risks. Safety officers, plant inspectors and third‑party auditors are the primary buyers. The supplier can dispatch stocked items from Zhengzhou within three working days, but exact minimum order quantities, incoterms and payment conditions must be confirmed directly with the supplier before placing an order.

Sourcing Gastec Gas Detector Tube NO.7LA from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Before placing an order, verify that the tube’s detection range, shelf life and quality‑control number match your safety requirements. Request a copy of the calibration certificate and the supplier’s ISO/SGS/SEI certificates to confirm conformity with your internal standards. Also confirm that the product is intended for phosphine detection and not another gas.
The supplier ships from Zhengzhou, China and can usually dispatch stocked items within three working days. Buyers should agree on incoterms - commonly FOB Zhengzhou - and clarify payment terms such as T/T or L/C. Because the listed response rate is currently zero, it is advisable to obtain a written acknowledgement of the agreed MOQ, lead time and shipping schedule before confirming the purchase.
For quality assurance, arrange a third‑party inspection of the batch before loading, and request the supplier’s test report for reagent stability. Ensure that the tubes are stored in temperature‑controlled containers during transit to preserve their shelf life. Retain all documentation - including MSDS, calibration certificate and packing list - to facilitate customs clearance and traceability.
