Who uses the Universal Vaping Machine

Hardware Qualification

Does this cartridge leak? Clog? Fail to produce vapor?

Before committing to a hardware supplier, you need to know how their cartridges actually perform — not on a spec sheet, but under real puffing conditions with your oil, at your target wattage, over hundreds of puffs.

The UVM runs cartridges to depletion while logging pressure drop (clogging indicator), vapor density (output consistency), and coil resistance (electrical stability) on every single puff. A cartridge that clogs at puff 150, leaks oil into the airpath at puff 300, or produces burnt hits above 4W — you'll see it in the data before it reaches consumers.

With the 4-channel system, test four candidate cartridges from different suppliers under identical conditions in a single session. One run gives you a direct, quantitative comparison.

Oil & Formulation Comparison

Which formulation performs best across your hardware?

Different oil formulations — varying ratios of distillate, terpenes, and cutting agents — behave differently in the same cartridge. Some produce more vapor. Some clog faster. Some deplete unevenly. The only way to know is to test them side by side under controlled conditions.

Load four formulations into identical cartridges, set the same puff profile and power level, and run them simultaneously. The UVM produces per-puff vapor density, pressure drop, and total puff count data for each — giving you a direct, objective comparison of how each oil performs in your chosen hardware.

This workflow is especially valuable for formulation service providers developing custom blends for multiple brand clients, and for MSOs optimizing a single formulation across their product line.

Puff Count Verification

Do your label claims hold up?

Consumers see "300 puffs" on the package. Regulators want to know if that's true. Your competitors want to know if they can beat it. The UVM answers the question definitively.

The integrated IR vapor density sensor detects when a product stops producing aerosol, giving you the exact standardized puff count under your chosen conditions. Run the same SKU ten times and you'll have mean, standard deviation, and min/max — the statistical basis for a defensible label claim.

This is becoming a regulatory requirement in multiple jurisdictions. Canadian cannabis regulators already expect puff count data. Having standardized, instrument-generated results puts you ahead of the curve.

Power Optimization

What wattage gives the best performance for a given cart/oil combo?

Too low and you get thin, unsatisfying vapor. Too high and you get burnt hits, accelerated clogging, and potentially harmful thermal degradation products. The optimal wattage depends on the specific combination of cartridge hardware and oil formulation — and it's different for every product.

The UVM's 510 power cables bypass consumer batteries entirely, delivering precise, software-controlled wattage directly to the coil. With the 4-channel system, run the same cartridge/oil combination at four different power levels simultaneously. In a single session, you'll know exactly where the sweet spot is — and where the failure modes begin.

Batch Consistency

Statistical QC across production batches

A single cartridge test tells you about that cartridge. Ten cartridges from the same batch tell you about your manufacturing process. The 10-channel UVM runs ten units simultaneously under identical conditions, producing the statistical data you need for real quality control.

Track batch-to-batch variation in puff count, pressure drop trends, and vapor output. Identify supplier quality drift before it becomes a consumer complaint. Build the QC dataset that demonstrates consistency to regulators, retail partners, and consumers.

For high-volume operators processing thousands of units per week, even a small sample from each batch — tested overnight, unattended — provides the statistical confidence that manual testing never can.

Canadian Market

Meeting OCS quality requirements

The Ontario Cannabis Store (OCS) — the exclusive distributor for Ontario, Canada's largest cannabis market — requires all vape product suppliers to meet strict quality assurance standards. All cannabis products sold by the OCS must provide certificates of analysis for every lot or batch submitted.

Several of our Canadian clients — including major licensed producers and MSOs like Organigram — came to Gram specifically to meet OCS testing requirements. The UVM provides the standardized, repeatable testing data these programs demand: pressure drop profiling, puff count verification, vapor output consistency, and emissions capture for chemical analysis.

Whether you're a licensed producer submitting new products to the OCS, or an existing supplier maintaining ongoing quality assurance, the UVM is the tool that gets you there.
