Universal Vaping Machine

One machine for every
vapor product on the market

The Universal Vaping Machine automates the entire process of generating, measuring, and capturing aerosol — under consistent, repeatable, programmable conditions. It runs e-cigarettes, cannabis oil cartridges, cannabis vaporizers, pod systems, disposable vapes, and heated tobacco products, plus combustible products such as pre-rolls and tobacco cigarettes — any ENDS, aerosol-, or smoke-generating device.

Define your puff profile (volume, flow rate, rest interval, number of puffs), connect any product, attach your capture method, and press start. The system runs for hours, days, or weeks with no human intervention, logging per-puff data on pressure drop, vapor density, and coil resistance.

Validated for both vapor and combustible testing — under ISO 20768 (vapour products) and ISO 3308 / ISO 4387 (combustible cigarettes).

No manual operation. No inconsistent batteries. No cleaning. Just data.

Disposable Flow Path

Zero cleaning. Ever.

Smoke and cannabis vapor condenses into sticky, tar-like residue inside tubing, valves, and chambers. Competing machines require hours of disassembly and solvent cleaning between runs — and still risk cross-contamination.

The UVM's entire vapor-contact flow path is disposable. Tubing, fittings, filters — swap the whole thing in under 5 minutes. For high-throughput labs running dozens of samples per day, this saves hundreds of hours per year.

Multi-Channel Experiments

Same product. Different conditions.
One test session.

The 4-channel and 10-channel systems run fully independent channels. Each channel has its own pump, sensors, and power supply — so you can test identical products at different power levels simultaneously.

Set four different wattages, press start, and in a single session you'll know exactly how power affects clogging, vapor output, pressure drop, and puff count. Or compare four batches, four formulations, or four hardware designs under identical conditions.

Pressure Sensing

Quantify clogs, leaks, and draw resistance

Each channel has a dedicated pressure sensor that records the pressure drop across the vapor product on every puff. This quantifies how "tight" or "loose" a product draws, detects clogging trends over time, and flags catastrophic leaks or blockages automatically.

The system also supports pre-test and post-test filter pressure drop measurement with linear interpolation — isolating the vapor product's contribution from the filter's contribution.

Endpoint Detection

How many puffs are really in that product?

Integrated IR-based vapor density sensors on each channel measure relative aerosol output in real time. A single-click "run until depleted" mode puffs continuously until vapor is no longer detected.

The result: the total standardized puff count of a product. A critical metric for QC, regulatory compliance, and verifying consumer-facing label claims.

Device Lifecycle

Run it until it dies

Complete device lifecycle testing from first puff to last. The UVM runs continuously — days or weeks unattended — recording per-puff data throughout the entire lifespan of the product.

Track how pressure drop, vapor output, and coil resistance evolve over hundreds or thousands of puffs. Identify exactly when and how a product fails: gradual clogging, sudden leak, coil degradation, or battery exhaustion. Critical for hardware qualification and regulatory submissions.

Aerosol Capture

Capture vapor for any downstream analysis

The Gram UVM is highly configurable and is commonly used with a wide range of collection and exposure apparatus:

• Disposable PTFE fiber cartridge filters (Gram-manufactured)
• Cambridge filter pads
• Gas impinger tubes
• Cell culture exposure chambers
• Rodent nose-cone exposure systems
• Dilution/aging chambers

This makes the platform suitable for gravimetric analysis, chemical profiling (heavy metals, carbonyls, VOCs), toxicological studies, and regulatory submissions.
