In the room, he had a laminar flow hood that used to make E-Juice in. The laminar flow hood prevents contamination of the air going over the bottles.

The flavorings he uses are stored in amber dropper bottles with a 1ml dropper included. When he needs to make a large batch of E-liquid, he uses lab specific glass beakers and cylinders to measure accurately and consistently. Spreadsheets are used to record ratios needed for any PG/VG ratio or nicotine level.

When steeping or curing the juice he lets the bottles sit in industrial grade jewelry cleaner where the E-Liquid will become homogenous only after a few short hours. All glassware are cleaned and washed after every mixing to avoid contamination of flavors or nicotine.
