Coplin Staining Jar, PP, Domed Cap

The StemAids Coplin Staining Jar, PP, Domed Cap is a laboratory slide staining jar designed for holding microscope slides upright during staining, washing, fixing, rinsing, and slide preparation procedures. It is suitable for schools, colleges, biology laboratories, pathology training labs, histology labs, cytology labs, microbiology labs, research laboratories, and routine microscopy work.

Product Description

The StemAids Coplin Staining Jar is made from durable polypropylene and is designed to hold standard microscope slides securely inside a grooved chamber. The internal grooves keep slides upright and separated, helping users stain or rinse multiple slides at one time with controlled reagent contact.

The domed shallow-thread screw cap helps cover the jar during staining procedures, reducing reagent evaporation, dust exposure, and accidental contamination. The polypropylene construction makes the jar lightweight, break-resistant, and practical for classroom and laboratory environments where glass staining jars may be more prone to breakage.

This staining jar is useful for biology practicals, histology staining, cytology preparation, microbiology slide staining, blood smear staining, educational microscopy, and routine laboratory slide processing.

Safety and Handling Guidelines

• Use gloves, safety goggles, and lab coat when handling stains, fixatives, or biological samples.
• Verify chemical compatibility before using strong solvents, acids, bases, or aggressive staining reagents.
• Do not use cracked, warped, chemically damaged, or leaking jars.
• Do not overfill the jar, as reagent may spill when slides are inserted.
• Handle microscope slides carefully to avoid glass cuts.
• Use slide forceps when removing stained or wet slides.
• Do not tightly close the cap during autoclaving unless the supplier specifically permits it.
• Dispose of used stains and biological waste according to laboratory SOP.
• Clean the jar after use to prevent stain build-up and cross-contamination.
• Store in a clean, dry place away from heat, direct sunlight, and incompatible chemicals.

Quality and E-E-A-T Notes

The StemAids Coplin Staining Jar, PP, Domed Cap supports evidence-based microscopy preparation by keeping slides upright, separated, and immersed in controlled reagent volume.

FAQ

1. What is the StemAids Coplin Staining Jar used for?

It is used for staining, fixing, washing, and rinsing microscope slides in biology, histology, cytology, microbiology, and pathology work.

2. What material is the jar made from?

It is made from polypropylene, also called PP.

3. How many slides can it hold?

It can hold up to 10 standard microscope slides back-to-back or 5 single slides, depending on the loading method.

4. What slide size is compatible?

It is suitable for standard 25 × 75 mm / 1 × 3 in microscope slides.

5. What is the purpose of the grooved interior?

The grooved interior keeps slides upright, separated, and properly positioned during staining or rinsing.

6. What is the benefit of the domed cap?

The domed screw cap helps cover the jar, reduce reagent evaporation, and protect slides from outside contamination.

7. Is the jar autoclavable?

Many polypropylene Coplin jars are autoclavable, but the cap should usually be loosened or removed during autoclaving. Always follow the supplied product instructions.

8. Can it be used with all stains?

It can be used with many routine laboratory stains, but chemical compatibility should be checked before using strong solvents or aggressive reagents.

9. Is it better than a glass Coplin jar?

PP Coplin jars are lightweight and break-resistant, while glass jars may offer better compatibility with some solvents. The best choice depends on the reagent and laboratory procedure.

10. How should the jar be cleaned?

Empty the reagent safely, rinse the jar with suitable cleaning solution, remove stain residues, dry completely, and store it covered.

11. Is this suitable for school laboratories?

Yes, it is suitable for school biology labs, college labs, microscopy classrooms, and STEM practical sessions under supervision.

12. How should the jar be stored?

Store the jar clean and dry with the cap loosely fitted, away from heat, dust, moisture, direct sunlight, and incompatible chemicals.
