Whether you are fitting out a new wing or upgrading a decades-old lab, the same rule applies: equip for the experiments on your syllabus first, and let ambition grow with the budget.
Phase one: the non-negotiables
Every practical science room needs safe chemical storage with ventilation, a first-aid station including an eyewash supply, a fire extinguisher rated for chemical fires, and lockable storage for dangerous reagents. Furniture comes next — chemical-resistant benchtops, stools at the right height, and sufficient sockets placed away from water points.
Phase two: core apparatus
Microscopes (one per two students for biology classes), glassware in institutional quantities, burners with proper gas or spirit supplies, and measuring instruments spanning the syllabus range. Buy a few spare items of the pieces students break most often — thermometers and measuring cylinders — rather than pausing practicals when one drops.
Phase three: the differentiators
Digital equipment raises the standard of teaching: a digital microscope with a screen the whole class can see, data-logging sensors, and a preparation-room centrifuge. This is also where a good supplier relationship matters — apparatus needs recalibration and occasional replacement parts.
Safety is a syllabus item too
Train teachers on the safety equipment, run a termly drill, and keep a consumption log for reagents. An inspection-ready laboratory protects your students and your institution's reputation.
