Three buyers, one shelf
On this page11
The school
Buying in multiples of a class, with a budget cycle, a storage cupboard and somebody responsible for what is in it. Consistency across thirty units matters more than the perfect unit.
And a school is a workplace
Which is why the formaldehyde standard is in this property at all. The exposure limits and the labeling requirements apply to employees, and a teacher handling preserved specimens is one.
The parent
Buying one or two containers for a home chemistry set or a science fair project. No workplace standard applies, and the hazard in the kitchen is identical to the hazard in the classroom.
The student
Who is the one actually handling it, and who is the reason the closure decision matters more here than the archetype suggests.
The six leaves split across them
Classroom specimen and microscope slide prep are the school. Home chemistry and science fair sample are the kitchen table. pH test sample and crystal growing are both.
And the archetype was written for neither
ind-lab: reagent or sample, autoclavability and chemical resistance, 10 to 1,000 mL. That describes a working laboratory, which is the one buyer this group does not have.
Which is not a complaint
A laboratory archetype is the right nearest neighbor for a classroom. The point is that it imports a requirement, autoclavability, that the shelf cannot answer and the buyer rarely needs.
What a classroom actually needs
Thirty identical containers, legible labels, a closure a fourteen year old can use, and a material that will not crack when dropped on a laminate floor.
What a home needs
One container, a closure a younger child cannot open, and something that can be put away out of reach. 44 child resistant closures on this shelf are for exactly that.
Read the containers section with the buyer in mind
The same 414 containers serve all three, and which third of them matters depends entirely on who is asking.
