Grab Sampling
Manual and automated solutions for liquid, gas, cryogenic and demanding process applications, supported by application-specific design and in-house testing.
Representative, Safe & Emission-Free Grab Sampling Across Critical Industries
Spirare Energy is a pioneering manufacturer and solutions provider for high-integrity, closed-loop grab sampling systems in India and worldwide. Our systems are custom-engineered to extract truly representative samples of volatile liquids, toxic gases, high-viscosity slurries, and cryogenic liquefied gases while guaranteeing zero operator exposure and zero fugitive atmospheric emissions.
We engineer and manufacture purpose-built closed-loop sampling solutions across four primary process domains:
- Liquids: Closed-loop septum bottle samplers featuring non-coring dual-needle containment, fast loops, and fixed-volume chambers (LS, LV, LI, LB Series).
- High Viscous: Robust RAM-type in-line piston samplers that penetrate pipeline wall crusts and dead zones, equipped with thermal jackets and solvent flush stations (LR Series).
- Liquified Gas: Pressurized liquefied gas systems equipped with internal outage dip tubes or expansion chambers meeting ASTM D1265 and GPA 2174 (GS6–GS11).
- Gas: Emission-free cylinder samplers with fast-loop bypass routing, multi-valve synchronized linkages, and inert Nitrogen purge manifold connections (GS Series).
Every Spirare sampling system is fabricated, assembled, and pressure-tested in our ISO 9001 certified facility, backed by complete material test certification (EN 10204 3.1), hydro-testing, and helium leak testing—delivering dependable performance across oil & gas, refining, petrochemical, chemical, and clean energy facilities.
Liquids – Closed-Loop Bottle Samplers with Dual-Needle Containment
Spirare Energy offers high-precision liquid sampling systems engineered for representative, closed-loop collection of low-to-medium vapor pressure process liquids across refineries, petrochemical complexes, and chemical processing facilities.
Utilizing sealed septum collection bottles and specialized non-coring dual-needle dispensing assemblies, our liquid samplers ensure complete operator safety by preventing volatile organic compound (VOC) exposure and chemical splashes during the sampling sequence.
Available across the LS Series, LV Series (fixed volume chambers for hazardous media), LI Series, and LB Series, these units can be equipped with continuous fast-loop circulation, inert gas needle purging, and bottle enclosure cooling or heating to suit extreme process conditions.
- LS Series septum bottle samplers with dual-needle vent and fill mechanisms
- LV Series fixed-volume chambers preventing overfilling of toxic or volatile media
- LI & LB Series in-line process connections for minimal piping modification
- Wetted parts in SS 316/316L, Hastelloy® C-276, Monel®, or PTFE lining
High Viscous – RAM-Type In-Line Samplers with Zero Dead-Zone
Designed specifically for difficult process media where conventional samplers clog, Spirare Energy's LR Series In-Line Liquid Samplers handle high-viscosity liquids, polymers, asphalt, resins, slurries, and crystallizing fluids with zero dead volume.
The heavy-duty RAM piston strokes directly into the center of the process pipe to break through internal crusts or sludge layers, extracting a truly representative fluid sample without product stagnation.
To prevent viscous fluids from solidifying within the sampling path, systems can be equipped with integrated steam or electrical heating jackets, cooling jackets, and solvent flush stations that thoroughly clean wetted passages after each cycle.
- Rugged RAM-type piston extending through pipe wall to eliminate stagnant dead space
- Available with soft or metal-to-metal seating for abrasive and high-temperature service
- Thermal steam/electrical jacketing preventing crystallization and premature freezing
- Integrated solvent back-flushing connections for automatic line decontamination
Liquified Gas – Closed-Loop Systems with Outage Tube & Expansion Chamber
Spirare Energy's Liquified Gas Sampling Systems (GS6–GS11) are custom-engineered for the safe, representative, and emission-free collection of pressurized liquefied gases, including LPG, propane, butane, propylene, and volatile light hydrocarbons.
Because liquefied gases expand dramatically with minor ambient temperature rises, our systems feature internal outage dip tubes or secondary expansion chambers to guarantee a mandatory minimum 20% vapor headspace, fully complying with ASTM D1265 and DOT/TPED safety regulations.
Equipped with single-handle synchronized valve linkages, continuous fast-loop routing, and dedicated Nitrogen purge connections, the system clears connection lines prior to uncoupling, eliminating hazardous VOC discharge and operator exposure.
- Full compliance with ASTM D1265, GPA 2174, and DOT/TPED transportation codes
- Precision internal outage dip tubes (10% to 60%) or external expansion chambers (75cc–300cc)
- Single-handle multi-valve interlock preventing operational sequencing errors
- Sulfinert® and SilcoNert® surface treatments available for trace sulfur and H2S accuracy
Gas – Emission-Free Cylinder Samplers with Fast-Loop Bypass
Spirare Energy's GS Series Gas Samplers are engineered for the safe, representative, and emission-free extraction of pressurized gases, natural gas, syngas, toxic vapors, and hydrogen gas mixtures.
Using DOT/TPED certified transportable sample cylinders fitted with high-integrity quick-connect couplings, the GS Series establishes a completely sealed flow loop. Fast-loop bypass routing maintains process velocity, delivering fresh representative sample directly to the cylinder inlet.
Integrated Nitrogen purge lines and flare vent routing manifolds depressurize and decontaminate the quick-disconnect fittings prior to cylinder removal, safeguarding plant technicians from toxic chemical contact.
- DOT/TPED certified transportable sample cylinders in SS 316, Monel®, or Hastelloy®
- Continuous fast-loop filtration ensuring real-time representative gas extraction
- Integrated N2 purge and flare header blowdown manifolds for clean uncoupling
- Available in standalone panel, heated/insulated enclosure, or automated skid designs
