What’s on the Sterilisation & Disinfection poster
A 6-row table: Method · Kills · Used for.
Method against what survives it.
- Autoclave, 121°C — Everything, including spores — Instruments, media, waste
- Dry heat oven — Everything, slower — Glassware
- Filtration 0.22 µm — Bacteria, not viruses — Heat-sensitive liquids
- UV — Surface organisms — Cabinets, water
- Alcohol 70% — Most vegetative cells — Skin, surfaces
- Bleach — Most, including spores at strength — Surfaces, spills
70% alcohol works better than 100%: some water is needed for it to penetrate the cell and denature proteins.

- Who is the Sterilisation & Disinfection poster for?
- Sterilisation & Disinfection belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning microbiology can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Sterilisation & Disinfection poster?
- Sterilisation kills everything including spores. Disinfection does not. A wall chart earns its place by being glanceable from where the work is happening, so Sterilisation & Disinfection belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Sterilisation & Disinfection?
- Antibiotic Resistance, How Antibiotics Work and Aseptic Technique sit alongside Sterilisation & Disinfection in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Antibiotic ResistanceHow Antibiotics WorkAseptic Technique
- Is the Sterilisation & Disinfection poster free to download and print?
- Yes. Sterilisation & Disinfection downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Sterilisation & Disinfection poster print at?
- Sterilisation & Disinfection is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Sterilisation & Disinfection loses nothing.Printing guide
