How to Choose Educational Lab Equipment for Schools: Six Tests

Students learn science best through practical investigation. A well-equipped school laboratory lets them handle apparatus, take readings and observe results for themselves. But choosing educational lab equipment is harder than it looks. Catalogs are long, and two items with the same name can differ a lot in quality. This guide gives six tests to apply to any item, then works through three examples of applying them in a secondary school.

Six tests for choosing educational lab equipment

1. Does it fit the syllabus?

Start with the practicals your students must do, not with the catalog. List each practical in the syllabus and the apparatus it needs. Anything that does not serve a practical can wait. This keeps the budget on what students will actually use.

2. Is it for students or for the teacher?

Some items are made for the teacher to show at the front, such as large models or demonstration meters. Others are made for students to use in pairs, such as small balances and hand lenses. If the syllabus asks students to take their own readings, buy student sets in enough numbers.

3. Will it survive daily use?

School apparatus is handled by many students each week. Look for sturdy stands, thick glass and clamps that do not strip. Plastic models should not crack at the joints. Ask for clear photos of the exact model before you order.

4. Is it safe for the age group?

For heating, glassware should be borosilicate 3.3 glass, the type set out in ISO 3585. Electrical kits should run at low voltage. Every item with a flame, heat or chemicals needs a clear safety note. Your school's safety officer and the maker's manual should set the rules for each item.

5. Does it come with a manual?

Good educational lab equipment comes with a short guide. It should show how to set up the item, run the standard experiment and care for it. This helps new teachers and saves lesson time.

6. Can you get spares?

Glassware inevitably breaks, and bulbs, fuses and small components gradually wear out. Before you order, check which spares each item needs and whether the supplier can send them. Buying spares with the main order is usually cheaper than sending for them later.

Worked example 1: choosing a balance

Suppose a chemistry department needs balances for its quantitative weighing practicals. Here is how the six tests progressively narrow the choice.

• Syllabus: most school practicals weigh a few grams of solid, so a capacity of a few hundred grams is enough.
• Students or teacher: students weigh in groups, so one balance per group beats one precise balance at the front.
• Durability: a triple beam balance has no electronics to fail and suits student use; add one electronic balance with 0.01 g readability for exact work.
• Safety, manual and spares: ask for a set of check weights and the care guide with each balance.

The same tests apply to safety wear. Lab coats, goggles and a laboratory safety chart pass test 1 for every practical, so they come first. See our chemistry lab safety equipment and chemistry lab equipment pages.

Worked example 2: models or specimens?

A biology teacher must choose between models, charts and real specimens. The tests help here too. Test 1: does the syllabus ask students to identify real tissue, or only to label a diagram? If labelling is enough, a flower model or educational charts will last for years. Test 3: plastic models survive handling far better than preserved specimens. Test 2: a large human anatomy model is a teacher's item, while dissecting dishes and slides are student items and need to be bought in sets.

Browse botany models, human anatomy models and educational charts. Zoology models are in the wider biology lab equipment range.

Worked example 3: a slide staining set

For slide work, test 1 asks which stains the syllabus uses. Test 2 says each group needs its own slides and cover glasses, but one Coplin jar or staining trough can serve a bench. Test 6 matters most: slides and cover glasses break constantly, so order them in bulk. Microtomes and staining items cover the rest of this kit.

Writing it into a spec or quote request

Once you have chosen your educational lab equipment, turn each choice into a short spec line. Include the item name, the key size or range, the material, and the quantity. For example: "Beaker, borosilicate 3.3 glass, low form, 250 ml, graduated, qty 40."
