Yeah, we all know the drill. But what is DIY vaping? DIY is the short form of Do It Yourself. Vaping refers to inhaling vapor from an electronic device such as electronic cigarette that uses heat to vaporize a solid or liquid. The vapor produced looks thicker than smoke but has a better smell and quickly dissipates into the air. A graduated cylinder is laboratory equipment that measures the volume of a liquid. It is narrow and cylindrical. It is calibrated with each line marked represents the amount of fluid metered. Large graduated cylinders are typically made of polypropylene, an ideal chemical resistant or polymethylpentene due to its transparency. This makes the containers less fragile than glass and lighter. Polypropylene can repeatedly be autoclaved though autoclaving more than 250 degrees Fahrenheit (dependent on the chemical formulation) can damage or warp these cylinders affecting accuracy. The percentage of the full scale (volume at top fill line) is the accuracy specification of graduated cylinders. Class B cylinders state efficiency of 1 % implying that a 100ml cylinder filled adequately will be precise to 99, 100 or 101ml. The same applies when loaded halfway in that the error on 50ml will be plus or minus 0.5ml. However, this error is bound to increase significantly. Whether you are a newbie to the vaping scene or prowess in the vaping visionary, calibrated containers are as crucial as your vaping supplies. Any shrewd enthusiast will tell you graduated cylinders are crucial to producing the perfect blend of diluted nicotine, diluents and flavor concentrate. Often beakers come in handy in measuring the volume of vaping ingredients during the diluting process. Graduated cylinders are highly reliable liquid measuring containers. They have smooth, clear measuring lines and easy to read pigment calibrations. One can quickly read the volume of each e-liquid component you are topping up to your mixture. These cylinders are available in choices of 100, 50, 25 and 10 milliliters. Graduated cylinders are often marked Total Delivered (TD) or Total Contained (TC). TD means the gradations accounts for liquid traces that remain in the cylinder after removal whereas TC shows that volume gradations are set for labware liquids. While using them, you will notice they are fitted with guards and bumpers around the upper portions to shield them when toppled. On the other hand, broad bases ensure the stability of the containers. Nowadays some graduated cylinders are available as separate attachments with the support. Cylinders not meant for mixing featured a specialized spout for easy pouring. Additionally, mixing cylinders have sealable tops and stoppers that ensure the liquid does not pour out accidentally or without your knowledge. Handheld handles lets you carry around your mixture as you continue with your mixing process. Having your e-liquid flavors all mixed by yourself can be cost-effective, fun and rewarding experience. It’s not complicated as you think. Just grab your few simple tools, favorite flavors and some unflavored nicotine, and you label yourself “the mix-master” in no time. Note that all juices used in electronic cigarette have at least three main ingredients; flavoring, nicotine and propylene glycol (PG) or vegetable glycerin (VG). Mix your juice with nicotine level ideal for you, mostly ranging from 6mg to 24mg. unflavored nicotine comes in high concentration and can be diluted to suit one preference. Be warned that undiluted nicotine is highly poisonous and is absorbed through the skin. So take extreme precautions while handling it. You can as well wear protective gear, and please keep it out children’s reach. Dilute the nicotine with Propylene Glycol or with vegetable Glycerin to the desired strength. PG makes the vapor and gives the “hit-like’ ‘throat feeling. VG on the other side is smooth and provides less of the “hit” feeling but produces more vapor. Majority vapers blend 80%PG to 20% VG while others go for 50/50. In flavoring, there is a lot of trial and error as it varies in the strength of flavor, personal taste, and equipment in use. You can start with 5% and work your way up. Flavoring is added in drops to avoid contaminating the measuring equipment. A single ml holds 20-30 drops.
