Vape cartridges are small, thin, and cylindrical, and they can be made of glass or plastic. They are pre-filled with oil or juice for vaping purposes and inserted inside a vaping device to create vapour. The longevity of a vape cartridge depends on how often it is used and how much vapour is created in each session. There are several ways to know when a vape cartridge is empty, including weighing the cartridge before and after use, observing the taste and throat sensation, and checking the amount of vapour produced. Other methods include looking for a blue light indicator, examining the viewing window, and checking for residue on the coils. Proper disposal of empty cartridges is important, and some local recycling programs accept vape cartridges as electronic waste.

What You'll Learn
Weighing the cartridge
Step 1: Weigh the cartridge before use
Use digital scales with high precision to weigh the cartridge before it is used. This initial weight will serve as a baseline for comparison later on. Make sure to write down the weight accurately to ensure an exact comparison later.
Step 2: Weigh the cartridge after use
Once the cartridge is close to depletion, weigh it again using the same digital scales. This weight will indicate how much oil has been consumed and how much is left in the cartridge.
Step 3: Compare the weight difference
By comparing the weight of the cartridge before and after use, you can accurately determine whether the cartridge is empty or if there is still some oil remaining. The weight difference will indicate the amount of oil consumed, and if the weight remains the same, it confirms that the cartridge is empty.
Step 4: Consider the design of the cartridge
Some cartridges have a transparent viewing window that allows you to visually inspect the oil level. This can be used in conjunction with weighing to cross-reference the amount of oil left. Additionally, some cartridges have a light on top that indicates when the amount of vapor remaining declines, providing another indicator to consider.
Step 5: Evaluate other signs
In addition to weighing, there are other signs that can help determine if a cartridge is empty. For example, when a cartridge is almost empty, the smell of the essential oils may change towards a smoky smell. Taste and throat sensations can also be indicators; when the cartridge is empty, the vapor may have a burnt taste, and the throat hit may become harsher and less pleasant.

Observing changes in taste and vapour production
Changes in the taste of vapour and vapour production are key indicators that a vape cartridge is almost finished. When the cartridge is close to being empty, the vapour will start to taste harsher and smokier. This is due to the vape cartridge being unable to buffer the heat, leading to the scalding of the remaining oil. As a result, the vapour will also feel smokier.
Another indicator is the reduction in vapour production. As the cartridge empties, the vapour production decreases, and users may notice little to no smoke escaping from the mouthpiece after several attempts at inhalation. This reduction in vapour output is often accompanied by a burnt or unpleasant taste, indicating that the coil is no longer functioning optimally.
Additionally, users may experience increased resistance when inhaling, signalling that the cartridge is nearly empty. This increased resistance can lead to a hot feeling in the mouth and a burnt taste, which can be unpleasant and harmful. Therefore, it is important to pay attention to these indicators and replace the cartridge or refill it to maintain a pleasant and safe vaping experience.
Furthermore, the weight of the cartridge can be a subtle indicator of changes in taste and vapour production. When a vape cartridge is full, it feels heavier, and users can hear the sloshing of the liquid. As the cartridge empties, it will feel lighter, and the liquid will no longer be audible. This change in weight can be a subtle indicator that the cartridge is running low, and users may need to prepare for a replacement soon.
To summarise, observing changes in taste and vapour production is crucial when using a vape cartridge. By noticing the indicators mentioned above, users can ensure they replace or refill their cartridges at the right time, maintaining the optimal performance of their vaping devices and avoiding unpleasant or harmful experiences.

Checking the viewing window
When checking the viewing window, look for the metal stem in the centre of the cartridge. At the base of this stem are a series of small openings or holes. These openings are crucial as they allow the oil or extract to pass through and come into contact with the heating element, where it is vaporized. When you can no longer see oil or extract covering these openings, it is a clear indication that your cartridge is almost empty.
However, it is important to note that you may still be able to get a few more draws from the cartridge even after the openings are visible. At this point, the oil level is extremely low, and you may experience a burnt taste or a decrease in vapour production. Therefore, it is recommended to refill or replace the cartridge as soon as you notice low oil levels through the viewing window.
In addition to checking the oil level, you can also inspect the colour of the liquid in the cartridge. An empty or nearly empty cartridge may exhibit discolouration or sediment at the bottom, indicating that the oil has been spent. Furthermore, if you are using essential oils, a change in smell can be an indicator that the cartridge is almost empty. Instead of the usual pleasant scent, you may notice a smoky smell.
While the viewing window is a useful tool, it may not always provide an accurate assessment of the oil level. Some cartridges have a different design, making it harder to visually determine the amount of oil left. In such cases, you may need to rely on other indicators, such as taste and vapour production, to conclude if the cartridge is empty.

Disposing of empty cartridges
Firstly, it is crucial to determine whether local recycling programs accept empty cartridges. Some recycling centres have specific guidelines for electronic waste disposal. If your local program accepts e-waste, ensure that you properly clean the cartridge of any remaining residue before taking it to the designated drop-off point. Many stores that sell vapes also accept empty cartridges for recycling.
If there are no local recycling options, consider using mail-back programs specifically designed for vaping cartridges. These programs are often associated with brands, such as HP's Planet Partners, which has been working for over 25 years to recycle cartridges. HP offers both drop-off locations and mail-back programs to make recycling convenient for consumers.
Additionally, some organisations, like the eCycle Group, work with various entities, including businesses, schools, churches, and nonprofits, to recycle cartridges and even provide fundraising opportunities. To ensure your cartridges are accepted, they must be on the pre-approved recycling price list and received in good condition, individually wrapped to minimise damage during transit.
By following these guidelines, you can properly dispose of empty cartridges, contributing to environmental sustainability and reducing waste in landfills. Remember to also adhere to any specific local regulations or guidelines regarding the disposal of electronic waste.

Extending the lifespan of cartridges
The lifespan of a cartridge depends on several factors, including its size, capacity, frequency of use, and duration of each use. Proper care and maintenance can also help extend the life of a cartridge. Here are some tips to help you extend the lifespan of your cartridges:
Storage
Store cartridges in a cool, dry place, away from direct sunlight and extreme temperatures. The ideal storage temperature for cartridges is between 50°F and 70°F (10°C – 21°C). Heat and light exposure can accelerate the degradation of the oil, affecting its quality and performance. Keep the cartridge upright during storage and avoid high humidity environments, as moisture can cause leaks and reduce efficiency.
Priming
Priming new cartridges before initial use is crucial. Priming involves taking a few short puffs without activating the heating element to saturate the wick with oil. This reduces the risk of dry hits and prolongs the cartridge's lifespan. Burning the wick by heating it while dry will reduce the performance of your cartridge permanently.
Cleaning and Maintenance
Regular cleaning can help extend the lifespan of your cartridge. Use a clean paper towel or cotton swab dipped in isopropyl alcohol to remove any residue or gunk from the cartridge and battery. Wipe down your cartridge periodically to prevent clogs from oil residue buildup, which can cause leaks and rapid oil depletion.
Oil Extraction
To access the last few drops of oil in your cartridge, you can use heat and gravity. First, unscrew the cartridge from the battery and hold it upright. Gently apply heat to the bottom of the cartridge using a hairdryer or by running hot water over it. Then, tap the cartridge's bottom against your palm to dislodge the remaining oil. You can also use a syringe to extract the oil by removing the mouthpiece and inserting the syringe into the open cartridge.
Usage Techniques
The way you use your cartridge can also impact its lifespan. Using the lowest temperature setting possible while still achieving a satisfactory vaping experience is advisable. Taking gentle draws helps prevent strain on the heating element and extends its lifespan. Higher temperatures will vaporize more oil, potentially wasting some before or after each puff. Additionally, longer, deeper pulls burn through oil faster than light, quick puffs.
