Polypropylene Suitcase with Pre-Cut Foam

Quick Answer: This polypropylene carry case with pre-cut foam is a hard-shell suitcase whose foam insert is scored into small columns. Columns are pulled out to make pockets shaped to the items being carried, such as meters, sensors, electrodes or small glassware, so each sits snugly during storage and transport.

Custom Pockets Without Cutting Tools

Pre-cut foam, often called pick-and-pluck foam, is a thick foam sheet scored into a grid of small columns that stay joined at the base. To make a pocket, you trace round the item and pull out the columns inside the outline. No knife is needed, and the result is a snug cavity that stops the item sliding or knocking against its neighbours.

The shell is polypropylene, a plastic that is light for its strength, copes well with knocks and does not absorb water. As a material, polypropylene also resists most dilute acids, alkalis and cleaning agents, so a splash of buffer or detergent wipes off the case without marking it.

For a science department, the value lies in organisation. A pH meter with its electrode and buffer sachets, a set of data-logging sensors with the powered USB hub that runs them, or a fieldwork water-testing kit can each live in its own case, and a missing item shows up at once as an empty pocket when the lid is opened.

Specifications

Care & Handling

• Plan the layout by placing items on the foam and drawing round them before plucking any columns; removed pieces cannot be refitted neatly.
• Leave at least two rows of foam between pockets and around the edges so the walls stay strong.
• Dry wet items before packing them; foam holds moisture, and damp can corrode metal parts or grow mould.
• Wipe the shell with mild detergent solution, and keep solvents off both the shell and the foam.

Applications

• Storing a portable pH or conductivity meter with its electrode and accessories between lessons
• Carrying data-logging sensors to fieldwork sites for stream or soil studies
• Keeping a demonstration set, such as slotted masses or optical components, complete from year to year
• Moving delicate items between buildings on a multi-site campus

Why Choose LabEquip

Departments that share portable equipment between rooms or take it into the field buy cases like this to prevent breakage and loss. LabEquip lists it in chemistry lab equipment; describe what the case needs to hold through the contact page so a suitable size can be matched.

Frequently Asked Questions

How do I shape the pre-cut foam?

Lay the item on the foam, trace round it with a marker and pull out the columns inside the line a few at a time. Remove fewer columns than you think you need, test the fit, and take out more only if the item is too tight.

Can pulled foam be put back if I make a mistake?

Loose columns can be pushed back into a pocket but will not hold as firmly as the original foam. A little foam-safe adhesive at the base can fix them, which is why careful planning before plucking saves trouble.

Is a polypropylene case waterproof?

Polypropylene does not absorb water, and a closed case keeps out rain and splashes. Whether it is sealed against immersion depends on its lid seal, so do not rely on it underwater unless it has a gasket.

Can I store chemicals in the case?

It is intended for equipment. Small sealed buffer or calibration sachets that belong with a meter are fine, but open or leaking chemicals should never go in foam, which soaks up spills and is hard to clean.

What is the difference between pre-cut foam and solid foam inserts?

Solid foam must be cut with a knife to make pockets, which is slow and gives uneven edges. Pre-cut foam is already scored into columns that are simply plucked out, so custom pockets can be made quickly without tools.

How should the foam be cleaned?

Shake out dust and vacuum gently with a brush attachment. For marks, dab with a damp cloth and mild soap, then let the foam dry completely with the lid open before packing equipment back in.
