Paraffin Block Storage Cabinet for Histology Lab – 14840 Wax Blocks, Steel Cabinet with Stainless Steel Base

Product Details

Paraffin blocks don't store themselves well. Stack them in a drawer and they slide around. Label them in boxes and you lose the box. And when your lab processes hundreds of tissue samples a week, the collection grows fast — faster than your filing system can keep up.

This cabinet is built for exactly that problem. It stores up to 14,840 standard paraffin blocks in a four-section unit, with each block sitting in its own dedicated slot. No stacking, no sliding, no lost blocks.

Why a Dedicated Wax Block Cabinet Matters

Most histology labs start with plastic bins or cardboard trays. They work fine for the first few hundred blocks. Then the problems start:

• Blocks slide and tip over when bins get jostled or moved
• Temperature shifts in the lab cause blocks to stick together in summer and crack in winter
• No clear indexing system — finding a block from six months ago means opening every box
• Dust and debris settle on exposed blocks, affecting section quality

A proper paraffin block storage cabinet eliminates all of these. The grid slots hold each block vertically, separated from its neighbors. The steel body seals out dust. And the labeling system on each drawer front means you can find any block in under 30 seconds.

Cold Rolled Steel Body – Lab-Grade Durability

The cabinet body is formed from cold rolled steel with a thickness that holds its shape under load. The surface is finished with electrostatic powder coating — the same standard used on medical-grade equipment.

What this means in a real lab:

• No corrosion. Humidity from tissue processors, staining baths, and general lab operations won't rust the cabinet. The powder coating is non-porous and chemical-resistant.
• No deformation. When you stack four sections (full height: 1,520 mm), the lower cabinets carry the full weight. Thinner steel would bow or warp. Cold rolled steel stays square.
• Easy decontamination. Unlike wood or MDF, steel doesn't absorb xylene, formalin, or other lab chemicals. Wipe it down with standard cleaner. No residue, no odor retention.

Labs that upgrade from plastic bins or wood shelving to steel cabinets report a measurable drop in block damage — fewer chipped corners, fewer cracked samples, fewer lost cases.

14,840 Blocks in One Stack

Single section: 3,710 paraffin blocks Full stack (4 sections): 14,840 paraffin blocks

Each section measures:

• Height: 360 mm (14.17")
• Width: 515 mm (20.28")
• Depth: 480 mm (18.90")

A mid-size histology lab processing 80–120 cases per day generates roughly 1,500–2,000 blocks per month. A single four-section cabinet holds 7–9 months' worth of blocks before you need to add capacity.

For large reference labs and third-party testing centers, the modular design means you can place two or three four-section stacks side by side, creating a dedicated wax block archive wall. Index by date, by case number, or by organ system — the drawer labels make it flexible.

Partitioned Grid Slots – Vertical, Stable, Organized

Inside each drawer is a partitioned grid with individual slots sized for standard paraffin blocks (7 mm thickness, standard cassette format). Blocks stand vertically — base down, top up — in their own compartment.

This design solves three common storage problems:

Modular Stackable Design – Expand as You Grow

Same as the slide cabinet in our line — this unit uses a stackable modular system. Each section sits on top of the previous one, locked in place by interlocking corners. No tools, no bolts, no brackets.

Use cases:

• New labs: Start with one or two sections. Your block archive stays compact while you're building volume.
• Growing labs: Add a third and fourth section when caseload increases. The new sections match the old ones exactly — same color, same dimensions, same drawer rails.
• Multi-location labs: Keep a single section in each satellite collection point (biopsy room, grossing station) and consolidate into the main archive stack later.

The external dimensions are identical to our slide storage cabinet. That means you can place slide cabinets and block cabinets side by side or stack them in any combination — one slide stack next to one block stack, two of each, whatever your space requires.

Silent Drawer Rails + Label Holders

Each drawer runs on ball-bearing slides — full extension, silent operation. You can pull a drawer completely out to access the back rows without strain.

The front of each drawer has a removable label holder. Use it for:

• Case number ranges
• Date ranges

• Specimen types (e.g., "GI biopsies," "Dermatology")
• Pathologist or technician initials

Labeling turns random storage into a real filing system. When your accreditation inspector asks how you track archived blocks, you point to the drawer labels and the index sheet.

Stainless Steel Base – Built for the Floor

The cabinet stands on a stainless steel base — not painted steel, not plastic feet. This matters because:

• Floor moisture. Labs get mopped. Condensation forms on cold floors. Stainless steel doesn't rust when it gets wet.
• Chemical exposure. Floor cleaners, disinfectants, and occasional spills won't corrode the base.
• Ground clearance. The base raises the cabinet about 80 mm (3.15") off the floor, making it easier to level on uneven surfaces and preventing direct contact with standing water.

On standard painted-steel cabinets, the base is the first place to rust — usually within 2–3 years in a wet lab. Stainless steel eliminates that failure point.

Specifications

Packaging & Shipping

Each section ships fully assembled. Open the box, place it on the base, stack the next section. That's it — no screws, no brackets, no assembly time.

Packing details:

• Corner foam protection for impact resistance
• Moisture-barrier wrapping for sea freight
• Cardboard outer carton with handling marks

For international orders, we pack by section to optimize shipping volume. A full four-section set ships on a standard pallet footprint.

Frequently Asked Questions

Q: What size paraffin blocks fit in this cabinet? A: Standard histology cassettes, approximately 7 mm in thickness. The grid slots are sized for the most common cassette formats used in diagnostic and research pathology. If you use non-standard cassettes (oversized, deep-well, or specialty formats), contact us with dimensions before ordering.

Q: Can I store slides in this cabinet too? A: No — this cabinet is designed for wax blocks only. The grid slots are sized for vertical block storage, not horizontal slide placement. We manufacture a separate slide storage cabinet with grooved tracks for glass slides. Both cabinets share the same outer dimensions, so you can stack or place them side by side.

Q: How do I prevent blocks from sticking to the cabinet in hot weather? A: The grid slots keep blocks separated, which prevents surface-to-surface fusion. However, if your lab temperature exceeds 30°C (86°F) regularly, consider installing climate control. Paraffin softens at around 55–60°C, but even at lower temperatures, long-term storage in heat can cause surface degradation.

Q: Is the cabinet fire-resistant? A: The steel body provides inherent fire protection — it will not burn, melt, or release toxic fumes in a typical lab fire scenario. However, this is not a rated fireproof safe. For labs with specific fire safety accreditation requirements, consult your compliance officer.

Q: What is the MOQ? A: MOQ is 1 section. Order one to test, order a full four-section set for a new lab, or order multiple sets for a large facility.

Q: Do you offer OEM or color matching? A: Yes. We can match a specific RAL color for the powder coating, apply custom drawer labels with your lab's numbering system, or add your institution's logo. Minimum quantities apply for custom color runs — contact us for details.

Q: How long does the powder coating last? A: Under normal lab conditions (neutral cleaning, no abrasive scrubbing), the powder coating maintains its finish for 8–10 years. Avoid strong acids, strong alkalis, or solvent-based cleaners — these can damage the coating over time.
