Innovation in the UK & EU Vape Industry: FEELM 2.0

Nov 09, 2023

Inter Scientific has recently completed device testing of FEELM 2.0.

The device has been confirmed to deliver an impressive 1,000 puffs while utilising 2mL of e-liquid (in accordance with the UK legal limit).

Test Results & Methodology

In order to substantiate the FEELM 2.0’s claims regarding puff count and consistency, we employed precise testing methodologies encompassing the following areas:

Puff count
Puff consistency
E-liquid volume
Nicotine concentration

You can find details of the performed testing and findings below.

Puff count

Puff count determines the number of puffs delivered to a user from a device before it runs out of e-liquid, battery power, or both. This attribute was determined using a calibrated multi-port puffing engine with end-point-detection, to accurately determine device end-of-life. All FEELM 2.0 devices tested demonstrated an impressive puff count exceeding 1,000 puffs.

Puff consistency and total aerosolised mass

Puff consistency testing determines the uniformity and reliability of the amount of e-liquid delivered across all puffs. This was calculated by weight difference per 40 puff block across the lifetime of the device. The FEELM 2.0 device delivered aerosol consistently with a mean total particulate mass variation of 3% RSD over the device lifetime.

The total aerosolised mass of e-liquid was determined by the total weight difference of the test devices across their lifetime. Across the three devices tested mean utilisation of e-liquid (the percentage of e-liquid that has been aerosolised) was 77%.

E-liquid volume

The method involves determining the weight of the device before and after extraction and using the density measured from the e-liquid extracted. TRPR restricts e-cigarette tanks to a capacity of no more than 2mL. The test measured fill volume for the FEELM 2.0 device was measured as 1.92mL, less than the TRPR 2mL limit.

Nicotine concentration

The testing of nicotine concentration establishes the quantity of nicotine present in the e-liquid. TRPR 2016 mandates that e-liquids must not exceed a nicotine strength of 20mg/mL.

Measured using an accredited test method, nicotine concentration was calculated to be 18.40mg/mL, below the TRPR 20mg/mL limit.

Conclusions

The comprehensive compliance testing conducted by Inter Scientific affirms that FEELM 2.0 consistently delivers a remarkable puff count, ranging between 1053 and 1099 puffs, thereby warranting a claim of at least 1000 puffs, which surpasses other popular like for like products on the market. The enhanced puff count is achieved through the increased efficiency of e-liquid aerosolization, whilst adhering to the 2mL e-liquid limit set out in TRPR 2016.

The FEELM 2.0 device was benchmarked against the requirement of TPD/TRPR 2016 and it was determined that the FEELM 2.0 adheres to the regulatory requirements for nicotine content and volume. The innovations embodied in FEELM 2.0 mark a notable advancement in the vape industry, promising greater product efficiency and benefits for consumers.
