Stainless Steel Sampling Bombs (Bottles)

Precision-built containers for safe liquid and gas sampling, made in Vadodara, India

Mahabali Industries manufactures, supplies and exports stainless steel sampling bottles, also called sampling bombs. They are used to collect liquid and gas samples at site, store them securely and carry them to the laboratory for testing and analysis.

Each bottle is built to withstand rough handling in transit, so your sample reaches the lab exactly as it was collected. We make them in SS 304 and SS 316 stainless steel, which offers high strength and dependable corrosion resistance across a wide temperature range.

Configurations and capacities
  • Single-ended, double-ended or triple-ended designs
  • Standard capacities of 250 ml, 500 ml, 750 ml, 1000 ml, 1500 ml, 2000 ml and 2500 ml
  • Custom sizes made to your requirement
Made to your specification
Every application is different, so we design sampling bombs around your sampling conditions. Pressure gauges, rubber septa, quick release couplings and other accessories can be added to suit your needs.
Transformer Oil Sampling Bottles / DGA Sampling Bombs
Our SS 304/316 transformer oil sampling bottles are made for collecting oil samples for testing as per IS 9434, IS 10593 and IS 1866. They are available in 250 ml, 500 ml, 750 ml, 1000 ml, 1500 ml and 2000 ml, or in custom sizes.

With more than 25 years of manufacturing experience, we supply bottles in large volumes and to customer-specific designs, with consistent quality. On-time delivery, responsive after-sales support and competitive pricing have made us a preferred supplier for organisations across India.

Gas Sampling Bottles

Our stainless steel gas sampling bottles are designed to collect and store gas samples and carry them safely from site to laboratory. SS 304/316 construction gives them strong resistance to creep and corrosion at varying temperatures.


Each bottle goes through a thorough integrity check and cleaning process so that no contaminants remain. Bottles can also be vacuum-treated to remove moisture and other traces. We make them in a range of sizes, pressure capacities, end connections and valve types to match your requirement.

High Pressure Sampling Bottles
  • Our high pressure sampling cylinders are made from seamless SS 304/316 pipe with extra wall thickness for greater strength and pressure capacity. The ends carry NPT connections, and other standard thread types and sizes are available.
    They handle both liquids and gases and can be single-, double- or triple-ended, or made to your design. Typical applications include:
    • Refineries and high pressure gas systems
    • Coal and natural gas power plants
    • Oil and gas pipeline construction
    • Sampling of corrosive and pressurised gases

Frequently Asked Questions

A DGA (Dissolved Gas Analysis) sampling bottle, or sampling bomb, is a sealed stainless steel container that collects a transformer oil sample without air contamination. It lets the sample be transported safely to a laboratory for gas analysis.
DGA detects gases dissolved in transformer oil that point to internal faults such as overheating, arcing or partial discharge. This allows problems to be caught early, before they lead to equipment failure.
Our bottles are manufactured as per IS 9434, IS 10593 and IS 1866, the standards that govern transformer oil sampling.
Stainless steel (grades 304 and 316), chosen for corrosion resistance and for keeping oil and gas samples uncontaminated until they reach the lab.

Yes. Our range covers liquid sampling (such as transformer oil), gas sampling and high pressure sampling.

We offer a wide range of sizes and pressure ratings, from standard to high pressure. Send us your requirement and we will confirm exact specifications.

Yes. We supply valves, fittings, connectors, flanges, couplings, gauges and hoses for complete sampling systems.
