Explore clinical microbiology in three dimensions with this microscope-slide model, inspired by an acid-fast-stained sputum smear containing Mycobacterium tuberculosis.
The design features contrasting raised forms representing material found within a prepared sputum smear, including background cells and slender acid-fast bacilli. This tactile format makes structures normally examined through a microscope easier to see, handle and discuss.
The model is ideal for introducing acid-fast staining, mycobacterial morphology and the laboratory investigation of tuberculosis. It can support clinical microbiology and biomedical science teaching, student revision, infection-prevention education, laboratory displays and STEM outreach.
Unlike a genuine sputum specimen or delicate prepared slide, the model is durable and contains no biological material.
Please note that this is a simplified artistic and educational representation. Genuine appearance varies with specimen quality, preparation, staining technique and viewing conditions. It is not intended to replace microscopy, validated reference materials, laboratory testing or diagnostic interpretation.
