Sampling Pump GV-100S
GASTEC Gas Sampling Pump GV-100S / GV-110S
Ergonomic. Leak-Proof. The World Benchmark Sampling Pump.
The GASTEC GV-100S and GV-110S manual gas sampling pumps are the worldwide benchmark for rapid on-site gas detection. Featuring an engineered contoured handle for effortless pulling, a patented vacuum flow completion indicator, and an integral ceramic tube tip breaker with internal glass shard collector, the GV series draws an exact 100 mL or 50 mL sample volume through GASTEC detector tubes every single time.
Exact 100 mL & 50 mL Stroke Volumes
Internal precision mechanical stop locks at half (50 mL) or full (100 mL) stroke position.
Patented Vacuum Finish Indicator
Mechanical pop-up indicator visibly pops back in when the air sample draw is 100% complete.
Built-in Ceramic Tip Cutter
Durable ceramic cutting edge cleanly scores and breaks tube ends with zero flying glass shards.
Integrated Glass Shard Catcher
Broken glass tips fall safely into a clear internal reservoir that empties with a quick turn.
Contoured Ergonomic Grip
Non-slip barrel and contoured pull handle minimize hand fatigue during repetitive field testing.
Intrinsically Safe & Spark-Free
Completely non-electrical, non-metallic spark risk construction safe in ATEX Zone 0 environments.
3 Simple Steps. Engineered for Fast, Repeatable Field Sampling.
Break Tube Tips
Insert both ends of the fresh GASTEC detector tube into the ceramic cutter hole and rotate 360° to cleanly snip.
Align & Pull Handle
Insert tube into pump inlet facing directional arrow, align red index marks, and pull handle out until it locks.
Verify Indicator & Read
Watch the white vacuum completion indicator at the rear of the handle; when it pops in, read color stain.
Precision O-Ring Seal
Lubricated fluorocarbon elastomer seals guarantee a strict vacuum seal with zero leakage.
Automatic Mechanical Lock
Spring-loaded locking pawl holds shaft firmly at 50 mL or 100 mL until released by 90° handle twist.
Direct Visual Flow Check
Eliminates guesswork so technicians know exactly when the sample draw is completely finished.
Confined Space Pre-Entry Testing
Checks sewers, storage tanks, and ballast tanks for O₂, CO, H₂S, and combustible hydrocarbons.
Marine & Tanker Cargo Holds
Monitors toxic gas build-up and fumigant residuals prior to stevedore and inspection crew boarding.
Oil & Gas Refineries
Conducts spot checks for sour gas leaks, VOC fugitive emissions, and pipeline flanges.
Emergency HazMat & Fire Response
Pairs with GASTEC multi-gas and chemical warfare tubes for instant incident assessment.
Occupational Hygiene & Factories
Measures worker exposure to solvent vapors, acid mists, and welding fumes.
Environmental Soil & Water Headspace
Extracts air samples from soil boreholes and water bottles to detect contaminated groundwater.
The Specs Speak for Themselves
Design metrics that make the GASTEC GV series the world's most popular gas sampling pump.
100 mL ± 1%
precision volumetric stroke accuracy ensures absolute measurement reproducibility
Zero Spark
intrinsically safe mechanical architecture safe for classified explosive atmospheres
Built-in Catcher
holds over 200 glass tube shards safely inside before needing a quick emptying
