The Gastec Gas Detection System NO. 35 is a disposable glass detector tube intended for on‑site measurement of sulphuric acid vapour (H₂SO₄). It provides a concentration range of 0.5 to 5 mg/m³ as stated by the supplier. A calibrated colour‑change scale printed on the tube enables direct visual reading. The tube’s shelf life is listed as two years from the date of manufacture.
The tube body is made from borosilicate glass, a typical choice for chemical‑resistant detector tubes. A silica‑gel matrix containing a specialised reagent reacts with H₂SO₄ vapour to produce a permanent colour change. The direct calibration scale is a standard feature of Gastec short‑term tubes, and the hermetic sealing at both ends protects the reagent from moisture ingress. Typical operating temperatures for such tubes span - 10 °C to 50 °C.
These detectors are commonly employed by chemical plant safety officers, environmental auditors and laboratory personnel for rapid verification of acid vapour leaks. Prospective buyers often cite the supplier’s two‑decade export record, its claim of 10 % faster shipment, and the ability to ship stocked items within three working days. As with any bulk purchase, confirm the preferred Incoterm and payment conditions directly with the supplier before finalising the transaction.

When ordering, verify that the tube number (35), target gas (H₂SO₄), measuring range and shelf life match your application needs. Ask the supplier to provide copies of the ISO, SGS or SEI certificates cited in the product description to ensure conformity with your quality system.
Discuss logistics early: the supplier claims a 10 % faster shipment speed and can ship stocked tubes within three working days. Agree on the Incoterm (e.g., FOB, CIF) and clarify payment terms such as T/T or L/C before confirming the purchase.
Arrange a pre‑shipment inspection that checks the printed quality‑control number on each tube and confirms the colour‑change scale against a reference standard. Request a test report or certificate of analysis for the reagent, and ensure that any required documentation (COA, MSDS) accompanies the consignment.
