Overview
The Nortel Unitorch is a classic, compact premix hand torch with a foot in both the scientific and hobby worlds. Rather than a bench burner, it’s a small, portable flame you hold and maneuver — the kind of simple, predictable torch that suits soft-glass work, assembly, and off-bench tasks where a mounted burner would be impractical.
What the Unitorch is
The Unitorch is a premix torch: fuel and oxygen are mixed inside the body before reaching the flame. Premix burners tend to be simple to light, stable, and predictable, which is exactly why this style has long been common for scientific and entry-level hand torching. It’s a hand-held tool, so its strength is mobility and simplicity rather than raw output. For the broader distinction, see surface mix vs premix torches and, on format, bench vs hand torch.
Who the Unitorch is for
This is a beginner-friendly torch for soft glass and scientific or hobby use. It’s a sensible compact flame for someone testing the waters or doing localized, hand-held work, and it earns a mention among approachable first flames in our best beginner glass torch guide. It is not a borosilicate or large-work tool — for that you’d step up to a Nortel bench burner like the Major or Rocket.
Fuel and oxygen
The Unitorch burns propane or natural gas with oxygen. Beyond that, Nortel doesn’t publish detailed figures for this torch — jet count, flame size, and exact oxygen LPM aren’t given in the catalog — so treat any specific numbers as something to confirm with Nortel directly. If you’re sizing an oxygen supply, our how many LPM does my torch need guide explains how to think it through.
Where it sits in the Nortel line
The Unitorch is one of Nortel’s hand torches, alongside the surface-mix Ranger and the premix Twin Fuel Handtorch. Among them it’s the compact, entry-level option for simple soft-glass and scientific tasks.
Before you buy
Budget for the whole system, not just the torch: oxygen (a concentrator or tanks), the correct propane or natural-gas regulator, flashback arrestors on both lines, didymium eyewear, and ventilation. New to plumbing a torch? Start with the fittings, hoses & connectors guide and the glass torch safety setup guide.
Editor’s note: Nortel publishes little detail on the Unitorch beyond its description as a classic compact premix hand torch with scientific and hobby use. Its exact jet count, flame size, oxygen flow (LPM), and current pricing aren’t published, so confirm those specifics with Nortel before purchasing.
Best for: Beginners and scientific users who want a simple, compact, hand-held premix flame for soft glass and off-bench tasks.
Not for: Borosilicate production, large work, or anyone needing a big bench flame — this is a small portable hand torch.

FAQ
- What is the Nortel Unitorch?
- It's a classic, compact premix hand torch with both scientific and hobby uses — a simple, portable burner you hold and maneuver rather than mount on the bench.
- Is the Unitorch surface-mix or premix?
- It's a premix torch: fuel and oxygen are mixed inside the torch before reaching the flame. Premix burners are simple to light, stable, and predictable, which is part of why this style is common for scientific and entry use.
- What can the Unitorch melt?
- Nortel lists it for soft glass and scientific/hobby use. As a small premix hand torch it isn't a borosilicate or large-work tool — for that you'd want a bench burner like the Major or Rocket.
- Is a hand torch right for me?
- It depends on your work. Hand torches are held and maneuvered, which suits assembly, spot heating, and off-bench tasks; bench torches are mounted for hands-free work. See our [bench vs hand torch](/guides/clusters/bench-vs-hand-torch) guide.
