Product Knowledge
Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
Preparing microscope slides means moving them through a sequence of stains, alcohols and clearing agents, and slide jars hold the slides during each step. Grooves inside the jar keep slides upright and apart so the reagent reaches both faces evenly. The Coplin jar is the classic small version; larger staining troughs take a full rack.
The reagents involved are aggressive, so the jars are made of chemically resistant glass with a lid to limit evaporation.
Slide jars are used for routine and special staining such as hematoxylin and eosin, for rinsing, dehydration and clearing steps, and for short-term slide storage. They are standard in histology, cytology and pathology labs, clinical diagnostic labs, microscopy preparation rooms, and teaching and research labs. A row of jars lined up in sequence makes a simple, low-cost manual staining line.
Each jar is formed in borosilicate or laboratory soda-lime glass with internal grooves spaced for standard microscope slides. Coplin jars hold 5 to 10 slides vertically; rectangular staining troughs take a slide rack of up to about 20. A ground-glass or screw lid keeps volatile solvents such as xylene and alcohol from evaporating between steps, and the glass stands up to common staining reagents.
Fill each jar so the reagent covers the stained area of the slides, place slides in the grooves with space between them, and keep the lid on between steps. Handle xylene and alcohols with good ventilation. Dedicate jars to specific reagents in your staining sequence to avoid carry-over, and rinse thoroughly before switching a jar to an incompatible solution. Replace reagents on a regular schedule.
We press or form the jars with their internal grooves in chemically resistant glass, then anneal them. Groove spacing, so standard slides fit, and lid fit are the key production checks. Options include vertical Coplin jars, horizontal jars, rectangular troughs, and printed reagent markings. Tell us your slide format and batch size and we’ll match a jar or trough.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
