E-liquid, or e-cig juice, vape juice etc., is the substance that is heated up, or vaporized, inside of an electronic cigarette or open system vaping device, that creates a vapor when heated, or atomized, which resembles actual smoke like one gets off of smoking a tobacco cigarette.

Your e juice pen operates with vape liquid, specifically, not dry materials or wax, but you can be even more specific. Vapers have to know what sort of e juice their pens will be compatible with. It’s not the battery you have to keep in mind so much as the clearomizer, cartridge, or tank. Here are some things to be aware of plus a few tips for selecting a flavor and brand of e liquid.

Coil Conservation

The simplest systems utilize the most basic coils. These are made from low-quality metal alloys which burn down rapidly under the high heat required to create vapor from e juice. Consumers who vape a lot will burn down a coil in less than a week. Moderate or light vapers could stretch that out to 10 days or two weeks. As they burn out, these coils can produce a burnt or acrid flavor in your vapor. Don’t blame the e juice: it is probably your heating element which caused this anomaly, so replace it proactively or, if a tank is disposable, don’t re-use it more than the recommended number of times.

Another important factor is coil build. Single coil setups are designed to work with thin liquids. They provide the minimum surface area e juice will come into contact with and produce the least vapor of all coil builds. Because of their design, simple coils become clogged by thick liquids. Always read the label on a brand of vape liquid. If it contains more than 50% vegetable glycerin this is too much. Even less VG would be preferable: say, 70% PG, 30% VG. Amounts of nicotine and flavoring do not affect viscosity enough to matter.

Better coils, such as dual vertical and Clapton designs or temperature-sensitive materials, tend to respond well to thicker e juice. The bottom dual or dual vertical set up creates more surface area and opens up to prevent clogging. Temperature-sensitive coils made from Nickel 200 or Titanium burn down slowly and don’t produce a burnt flavor but they can only be operated on advanced vaping mods featuring a temperature control setting. Ceramic coils, very popular these days, are even longer lasting and their flavor is equally clean. With organic cotton wicking, any coil tastes better than it does with inferior cotton or other wicking material. Now that you have installed better elements or more elaborately designed coils, it’s possible to put high-VG e juice to the test. This will produce an exceptional amount of vapor, especially at high settings.

Better Tanks

Another consideration is the material your tank or clearomizer tube is made from. Glass is the cleanest medium, but it should be reinforced Quartz or Pyrex. These are more durable than regular glass. As a vessel for your e liquid, glass is inert, meaning it won’t taint the taste of e juice which has been sitting in the tank for a while.When you buy a sub ohm tank it is usually made from glass to withstand high temperatures and not create fumes of plastic which would mix with e liquid vapor and ruin the taste. Glass is also suitable for e juice styles which notoriously cause lesser tubes to crack or become cloudy. Polycarbonate, acrylic, and plastic tubes generally crack or cloud under pressure from these flavors, such as lemon-lime or black licorice.

E Liquids that Crack Tanks

As you browse a selection of flavors, some companies thoughtfully add a note in small print but highlighted so you don’t miss it. The note says something to this effect: “it’s been reported that this style of e liquid is a tank-cracker.” It is always good to check a spicy or acidic style and if nothing is noted about tank-cracking, start a live chat with the company or call them to ask whether a brand will crack tanks. It’s advisable to check a style meant to represent citrus fruits, anise, or a cinnamon variety, for instance.


A lot of vapers learn about new e juices, determine favorite flavors, and simply enjoy the surprises they encounter when they sign up for a subscription. Subscription e juice firms are like wine clubs. You tell the company which types of e juice you definitely do or do not like and also the nicotine level you desire, if any. They package a number of bottles for monthly delivery and you don’t know what these bottles will be. All you are sure of is that the company will stay within your chosen category or categories although there are no guarantees you are going to like the flavors found in your box each month.

Categories are usually identified as tobacco, menthol, dessert, fruit, candy, and beverages. More detailed specifications might include coffee, tea, cocktails, floral, nuts, baked goods, or cereal.

Whichever ones you select, the company finds e juice styles which fit the profile. They might ask for details of any styles you absolutely won’t tolerate in case flavors overlap: cinnamon with menthol or custard with tobacco, for example. Non-subscription vendors list similar categories on their websites to help you find a brand and style to purchase. Firms that make a big variety of flavors offer the same divisions and also split their products into categories according to their suitability for regular or sub ohm coil structures.


A number of firms have proactively chosen to list the ingredients they make their e juices from and also tell consumers about their facilities. Companies such as Halo, VaporFi, and NicQuid make it very plain that their products are made from USP-grade ingredients, mixed in a US lab, and their labs are compliant with official food safety regulations. A number of firms have gone even further, submitting liquids for third-party testing to determine if they contain any of the several controversial chemicals which consumers are watching out for. They include diacetyl and acetyl propionyl. Manufacturers post these results as do many authorized resellers, satisfying the concern and curiosity of consumers so they don’t have to ask the question. Firms like these are getting ready to stand up to the FDA’s upcoming regulations.
