Laboratory Slide Staining Tray | Roundfin
1. Large capacity design holds up to 20 standard microscope slides (75 x 25 mm) in a single tray for batch H&E and special stain processing
2. Raised rails and grooved slots ensure individual slide separation, preventing slide-to-slide contact and ensuring uniform reagent access to all slide surfaces
3. Chemical-resistant polyoxymethylene (POM) or 304 stainless steel construction withstands repeated exposure to xylene, ethanol, hematoxylin, eosin, and clearing agents
4. Easy-grip handles on both ends for safe transfer between staining dishes with forceps or gloved hands; stackable design for compact storage
5. Compatible with all standard staining dish dimensions — fits Coplin jars, vertical staining dishes, and automated linear stainer racks
6. CE marked and manufactured under ISO 13485 quality standards for clinical histopathology laboratory use
Product Overview
Roundfin Slide Staining Trays provide a durable, chemical-resistant platform for batch staining of microscope slides in histology and cytology laboratories. Holding up to 20 standard 75 x 25 mm slides with individual grooved slots for uniform reagent access, these trays are compatible with all standard staining dishes and Coplin jars. Available in polyoxymethylene (POM) for chemical resistance and lightweight handling, or 304 stainless steel for maximum durability and autoclave compatibility.

Key Features
- 20-Slide Batch Capacity — Process up to 20 slides simultaneously in a single tray, optimizing workflow efficiency for high-volume histology laboratories processing 100+ slides daily.
- Individual Grooved Slots — Each slide rests in a dedicated grooved slot with raised rails, ensuring uniform reagent access to all slide surfaces and preventing slide-to-slide contact that could cause section damage or cross-contamination.
- Chemical-Resistant Construction — POM trays withstand repeated immersion in xylene, graded ethanols, hematoxylin, eosin, and all standard staining reagents. Stainless steel trays add autoclaving compatibility for sterile protocols.
- Dual Handle Design — Ergonomic handles on both ends allow safe, controlled transfer between staining dishes using forceps or gloved hands, minimizing the risk of dropping slides or reagent splashing.
- Universal Dish Compatibility — Designed to fit all standard Coplin jars (vertical slide), staining dishes (horizontal slide), and automated linear stainer slide racks for seamless integration into existing staining workflows.
- Stackable Storage — Trays nest securely when stacked, minimizing storage space requirements and protecting slide slots from dust and damage when not in use.
Applications
- Routine histology and pathology sample-preparation workflows
- Clinical laboratories processing compatible specimens, blocks or slides
- Research and teaching facilities using microscopy and tissue-processing supplies
- Laboratories confirming size, material and equipment compatibility before ordering
Frequently Asked Questions
How many slides does the tray hold?
Each tray holds up to 20 standard microscope slides (75 x 25 x 1 mm). The grooved slots provide approximately 2 mm of clearance between slides, ensuring uniform reagent circulation. For 1.2 mm thick slides, capacity is 18-20 slides due to slightly reduced clearance. For delicate protocols requiring extra slide spacing, load 15-18 slides per tray.
POM or stainless steel — which material should I choose?
POM is recommended for most routine H&E and special stain applications. It is lightweight, chemical-resistant, and economical. Choose 304 stainless steel if you require autoclave sterilization (121°C), process slides with aggressive solvents beyond standard histology reagents, or prefer the added durability and thermal stability of metal for long-term heavy use in high-throughput laboratories.
Are these trays compatible with automated slide stainers?
The trays are designed for manual batch staining and are compatible with standard Coplin jars and vertical staining dishes. For automated linear stainers (Leica ST5010/5020, Sakura Tissue-Tek Prisma, Roche Ventana), the trays can be used as loading racks but may require an adapter depending on the stainer's slide carrier specifications. Contact Roundfin for compatibility verification with your specific automated stainer model.
How should I clean and maintain the staining trays?
After use, rinse trays thoroughly with running tap water to remove residual staining reagents. Soak in warm water with mild detergent if eosin or hematoxylin residue is visible. For POM trays, avoid abrasive scrubbers that could scratch the slide slots. For stainless steel trays, ultrasonic cleaning is effective for removing paraffin and stain deposits from the grooved slots. Air-dry completely before storage. Replace trays when slide slots become worn or grooved rails show visible degradation.
