Deschem 6-Pack Borosilicate Glass Celsius Thermometers — 300mm
Product description
Set contents: six identical glass Celsius thermometers supplied together for batch use or backup.
Construction and materials: each thermometer is made from G3.3 borosilicate glass and contains an alcohol-based red indicator fluid. The stems are transparent so readings are easy to spot, and a small hanging hole near the top allows convenient storage on a peg or hook.
Dimensions and range: each unit measures 300 mm (12 inches) in length. The calibrated temperature span covers roughly ‑25°C up to 200°C, marked in degrees Celsius for laboratory and educational applications.
Usage notes: designed for general lab checks, educational experiments, and cross-referencing temperature controllers. They offer fine measurement precision when intact, but the glass is breakable and the printed numerals may fade with heavy handling. Handle gently and store via the hanging hole to prolong life.
Pros
- Wide temperature range suitable for labs
- Alcohol-filled for clear red indication
- Hanging hole for simple storage
Cons
- Fragile glass construction
- Markings can wear over time
- Some units may develop fluid gaps
VerdictThese six 300 mm G3.3 borosilicate thermometers deliver reliable Celsius readings across a wide range (‑25 to 200°C) and are useful for lab cross-checks and classroom use. They’re alcohol-filled with a hanging hole for easy storage. Expect good accuracy but handle carefully—glass is delicate and markings can wear.

Mixed reliability, reflects low cost
Glad there were extras because one didn’t register and another was off; one worked well. You get what you pay for.

Accurate for cross-checking
Solid thermometers. I use them to verify my temperature regulator; they agree with one another. Pleased so far.

Jamie Goodrich 4/5
They work but are very fragile
Functional and accurate, but extremely fragile—I sat on one by mistake. Don’t sit on them and they’ll be fine.

Fred 1/5
Fluid gaps made them unusable
I received four but all developed gaps in the red fluid, so readings are unreliable unless guessed. Not returnable.

Works but markings wear
They do the job, but the printed numbers fade too easily and I’d like a thicker stem.
