Technical Narrative

The Caplugs® Evergreen Slide-Fix™ is a purple HDPE screw cap for Slide-Fix™ PAP smear fixative jars. Purple Slide-Fix™ caps provide an additional color dimension for cytology batch routing systems where the more common colors (Orange, Fuchsia, Red, Green) are already assigned — purple is used to designate specialized cytology sub-types, overflow accession batches, or specific anatomic site designations within multi-category cytology batch routing schemes. With this addition, the Slide-Fix™ cap range now spans nine colors, providing the full color vocabulary needed for complex cytology batch routing protocols in high-volume anatomic pathology and cytology laboratories.

HDPE provides the chemical resistance required for prolonged contact with alcohol-based and Carbowax/PEG cytology fixatives, autoclave compatibility at 121°C for pre-sterilized supply, and consistent screw-thread engagement for leak-free fixative jar closure. All nine Slide-Fix™ colors share the identical HDPE material specification and thread geometry — color is the only variable.

At $106.17 per 1000/Bag — $0.1062 per cap. See the complete 9-color table above. All colors priced identically at $106.17/1000.

Slide-Fix™ PAP Jar Cap Workflow Compatibility — Purple

The purple HDPE cap provides cytology fixative jar closure:

Application Tube / Specimen Notes
Slide-Fix™ PAP jar capping Slide-Fix™ PAP smear fixative jars HDPE threads engage Slide-Fix™ jar neck thread
GYN cytology fixation Cervical, endocervical, vaginal smear fixation HDPE resists alcohol and Carbowax fixatives
Color-coded cytology batching Visual batch differentiation in cytology lab 9 colors for complete cytology batch routing protocol
Specialized batch routing Sub-type or overflow batch designation Purple/Yellow expand routing beyond 7-color schemes
Non-GYN cytology BAL, sputum, body fluid smear fixation Color routing for non-GYN vs GYN specimen separation
Replacement cap program Lost/damaged caps for Slide-Fix™ jars Exact thread for Slide-Fix™ jar necks
Cytology QC compliance CAP/CLIA accredited cytology lab closure HDPE cap per pre-analytical cytology protocol

Validate cap-to-jar thread fit with a sample before bulk purchase.

Chemical Resistance — High-Density Polyethylene (HDPE)

HDPE resists alcohol and Carbowax/PEG cytology fixatives. Autoclave-compatible.

Reagent / Condition Compatibility
Alcohol fixatives (EtOH, IPA) ✓ Excellent — primary cytology fixative
Carbowax / PEG fixatives ✓ Good — standard Slide-Fix™ formulation
Aqueous buffers ✓ Excellent
Dilute acids (<10%) ✓ Good
Autoclave (121°C) ✓ Compatible
Concentrated organics ✗ Not recommended at high concentration
