The Science Technician's Guide to Ordering Class-Set Lab Coats

If you're the one who actually opens the stock cupboard, you already know: nobody else in the school thinks about lab coats until a Year 9 pracs class walks in and there aren't enough that fit. This guide is written for the technician — the person who plans the order, unpacks the box, labels the coats, works out who wears what, and quietly reorders before anyone notices the stock thinning.

Start With Your Stock, Not a Catalogue

Before pricing coats, walk your prep rooms and count what you have:

• How many coats per lab? Note where sets live — lab benches, hooks, storerooms. Sets that "live" in three different rooms always drift out of balance.
• What's actually wearable? A coat that's intact, closes properly and isn't stained past rehabilitation stays in service. Coats with frayed cuffs, failed press studs or permanent chemical discolouration are done — they're PPE, not keepsakes.
• What sizes do you actually use? Most departments discover their set has drifted: a dozen mediums, one XXS and nothing that fits the Year 10s. A quick tally by size beats ordering "the same as last time."

Communal Class Sets or Student-Owned Coats?

This is the first decision every science department makes, and it shapes everything downstream:

Communal class sets live in the lab, get shared between classes and get laundered by the school. They suit departments that run practicals across many year levels and want every student covered without chasing families for orders. The trade-off is hygiene and laundry: shared coats need a washing routine between cohorts, and someone (usually you) owns that routine.

Student-owned coats are ordered by families, usually through the school's booklist, and travel with the student. They suit schools where practicals are concentrated in one or two year levels. The trade-off is coverage — there's always a handful of students who arrive without one, so most schools keep a small communal back-up set anyway.

Most departments land on a hybrid: booklist coats for the heavy-pracs years, plus a shared set of 10–20 for everyone else. If you're rethinking your approach, our guide to ordering lab coats for a whole class or year level covers the booklist side of the equation.

Sizing a Class Set: The Bell-Curve Rule

Shared sets don't need one coat per enrolled student sized exactly to each student — they need a distribution that fits whoever walks in. Teenage cohorts follow a predictable curve, so order to the curve, not to the roll:

For a standard 30-coat set across Years 7–12:

• Small sizes (XXS–XS): around 5 coats — your Year 7s and smaller Year 8s
• Medium sizes (S–M): around 15 coats — the bulk of the set; this is what most secondary students wear
• Large sizes (L–XL): around 8 coats — taller seniors and anyone layering a jumper in winter
• Extra large (2XL–3XL): around 2 coats — non-negotiable, because a student who can't fit a coat can't do the prac

The reasoning is simple: a slightly large coat is safe (sleeves roll up), a too-small coat is not. For the full working-out, see how many of each size to order for a class and our sizing chart, which maps every size from XXS to 3XL to school year levels.

White or Navy, Elastic or Traditional Cuffs?

Most science departments order white — it shows contamination clearly, which is exactly what you want in a lab. Navy is the practical alternative for departments tired of the laundering battle; white coats are $24 and navy $27 per coat, in sizes XXS to 3XL.

On cuffs: elastic cuffs hug the wrist and keep sleeves clear of burners, equipment and flames — the safer choice for science practicals and more comfortable for writing up results. Traditional cuffs sit open at the wrist. For class sets used across year levels, elastic is the recommendation that holds up best in practice. (Here's the cuff comparison in detail.)

Ordering by Purchase Order

Most schools order class sets on a purchase order. The process is deliberately light:

1. Get a quote first. Official institutional quotes are turned around within one business day, which keeps your P/O paperwork moving.
2. Submit the P/O. Upload the purchase order at checkout, or email it through with your size breakdown. There's no minimum order for P/Os — if your budget only stretches to replacing six coats this term, order six.
3. Sizes can be mixed freely. A class set is one order, not 30 separate line items.

If it's your first time ordering for the school, the step-by-step purchase order guide walks through the paperwork, and the bulk supplier checklist lists the twelve questions worth asking any supplier before you commit budget.

When You Order Matters

Dispatch is fast — orders leave within 24 hours, and standard shipping runs 5–7 days Australia-wide (express is 2–3 days). But the smart move is ordering before Term 1 or Term 3 booklist windows close, when supplier queues are longest and school admin is busiest. The timing mechanics are in when to order school lab coats around booklist season.

Reordering: Watch These Four Signals

A class set erodes predictably. Reorder when you notice:

1. Fit failures — a practical where several students are in coats that are visibly too small or too short
2. Wear points — frayed cuffs, failed studs, thinning elbows (replacement studs exist, but a coat can only take so many)
3. Cohort shift — the year level using the set has grown, or a new prac-heavy subject has been added
4. Stock imbalance — the mediums have vanished and only 3XLs remain, which means the set no longer matches the curve

A practical habit: do the stock walk once a term. Fifteen minutes, a tally sheet, and you'll never be caught short mid-prac.

Logos: Worth It for Class Sets?

If your coats are communal and shared, a school crest on the chest pocket has two jobs: it marks the coat as school property (they stop wandering home) and it looks the part at open days. Logo printing is free on orders of 10 or more coats — applied with direct-to-film printing that withstands 50+ washes, so the crest survives the laundry cycle the coat will live through. Turnaround adds 3–5 business days. For shared department sets, it's usually worth it.

Quick-Start Checklist

• Tally current stock by size and condition
• Decide communal vs booklist split for the year ahead
• Map needed coats to the bell-curve distribution
• Request an institutional quote (one business day)
• Submit the P/O with your size breakdown
• On arrival: label by size, assign storage, log the count
• Diary a termly stock walk

Frequently Asked Questions

How many lab coats should a school class set have? A working set is one coat per student in your largest prac class, plus 2–3 spares in the middle sizes. For most departments that's a 30-coat set, distributed to the bell curve above rather than ordered in equal sizes.

Do we need safety glasses with our lab coat order? Yes, if AS/NZS 2243.3 applies to your practicals — coats and eye protection go together. Safety spectacles are $5 a pair, so budgeting for a class set of glasses alongside your coats is a small line item that keeps the whole prac compliant.

Can we order class-set lab coats without a purchase order? Yes — schools order directly with a card through the Shop as well, and free shipping applies over $100. But for anything the finance office needs to track, a P/O is the clean path.

What if our size mix was wrong? Schools can exchange sizes within 7 days — unpack, check the fit against a few students, and swap any sizes that don't match your cohort before the set enters service. (See Returns & Exchanges.)
