20 mL Specimen Containers, Screw Caps, PPC, Green — 240-7020-G80 | 500/Bag | Caplugs® Evergreen

Histo-Click™ 20 mL Click-Top Specimen Containers, Green Caps — PPC, Non-Sterile, 500/Bag Unassembled

Technical Narrative

The Caplugs® Evergreen Histo-Click™ 240-7020-G80 is a 20 mL Polypropylene Copolymer (PPC) specimen container with a green click-top snap lid — purpose-engineered for histopathology tissue collection, formalin fixation, and cytology specimen workflows where one-hand container operation is critical in gloved surgical and grossing environments. The click-top closure engages and releases with a single thumb press, eliminating the screw-threading motion that requires two hands or wrist rotation in gowned and double-gloved settings. Supplied unassembled, 500 containers and 500 green caps per Bag, each unit arrives ready for immediate point-of-use assembly at the collection bench. Green caps enable color-coded specimen routing — commonly assigned to cytology, brushing, or lavage specimens to differentiate from fixed tissue batches.

PPC construction delivers the formalin resistance that histopathology workflows demand — compatible with 10% neutral buffered formalin (NBF) at standard tissue fixation concentrations — alongside the broader chemical resistance and low-temperature stability that makes PPC the preferred polymer for tissue collection containers handling diverse specimen types. The 20 mL volume accommodates gross tissue fragments, core needle biopsies, fine needle aspirate washes, cell brushing suspensions, and lavage fluid collections within a single vessel format, reducing the container-switching overhead of mixed-volume collection programs. Natural PPC tube body allows direct visual specimen volume assessment and morphology inspection without container removal from the specimen processing tray.

At $173.41 per 500/Bag — $0.3469 per container — the Histo-Click™ delivers click-top convenience at bulk economics that make full single-use adoption practical for high-volume histopathology cores processing 50–500+ specimens per day. The unassembled format allows pre-labeling or barcode application before capping, supporting integrated laboratory information system (LIS) workflows. Also available: 240-7020-B80 (Blue cap, $173.41/Bag); 240-7020-W80 (White cap, $173.41/Bag) — enabling full color-scheme procurement for specimen-type color-coding systems.

Technical Specifications — Caplugs® Evergreen

Clinical Workflow Compatibility — Histo-Click™

The Histo-Click™ click-top closure and PPC construction make it compatible with the following histopathology and clinical collection workflows:

Histo-Click™ containers are supplied Non-Sterile and unassembled. PPC is compatible with 10% NBF formalin at standard fixation concentrations. For applications requiring sterile containers, contact us for sterile variants.

Chemical & Environmental Resistance — Polypropylene Copolymer (PPC)

PPC delivers formalin compatibility at 10% NBF concentration, broad chemical resistance, and low-temperature storage stability — purpose-built for histopathology workflows.

Clinical & Research Laboratory Applications

The Histo-Click™ serves hospital and reference histopathology laboratories for surgical and endoscopic biopsy tissue collection; cytopathology departments for brushing, lavage, and fine needle aspirate specimen handling; urology and nephrology for kidney biopsy and bladder wash collection; autopsy and forensic pathology for organ and tissue sample collection; molecular pathology for tissue collection destined for DNA/RNA extraction and FFPE processing; oncology biobanking for tumor tissue archiving; and any clinical or research setting where one-hand click-top operation in a gloved or sterile-field environment is required. The 500/Bag bulk format supports high-throughput collection programs.

Frequently Asked Questions — Caplugs® Evergreen

Is the Histo-Click™ container compatible with formalin fixation?

Yes. The Histo-Click™ is molded from Polypropylene Copolymer (PPC), which is compatible with 10% neutral buffered formalin (NBF) at standard tissue fixation concentrations used in histopathology grossing protocols. PPC resists formalin-induced polymer degradation at routine fixation volumes and exposure times. For concentrated formalin (>30%) or extended immersion, validate with your reagent SDS before full-volume commitment.

What is the difference between click-top closure and screw-cap on specimen containers?

A click-top closure snaps open and shut with single-thumb pressure — no rotation, no threading. This is critical in gloved surgical and grossing settings where standard screw-cap containers require two hands or wrist rotation to open and reseal. The Histo-Click™ design enables one-hand container operation during tissue collection, reducing the contamination risk of setting down instruments to operate the container. Screw caps provide a more hermetic seal for transport and long-term storage; click-top is optimized for collection speed and gloved-hand usability at the point of specimen acquisition.

Are the Histo-Click™ containers BPA-free?

Yes. Both the PPC container body and the green PPC click-top cap are molded from virgin Polypropylene Copolymer containing no BPA and no phthalate plasticizers — suitable for histopathology, cytology, molecular diagnostics, and regulated laboratory environments.
