Glo-Stick

The Glo‑Stick 2E is a pre‑measured, single‑dose fluorescent dye capsule designed for HVAC/R systems. It allows technicians to inject the dye inline while charging refrigerant (or when connecting high side to low side) — making leak‑detection cleaner and more efficient. The capsule contains Spectroline dye, which the manufacturer states “glows brighter than the competition,” and is sized to match systems with higher capacity (approx lubricant 1.6–3 L / refrigerant 2.3–4.5 kg) according to the product guide.
