Coplin Jar
Product Code : LSK-BL-10227
Coplin Jar (SKU LSK-BL-10227) is a polypropylene staining jar whose grooved interior holds up to 10 microscope slides of 75 x 25 mm upright, while a cap with a built-in seal ring makes the jar leak-proof. It can be used to stain, rinse or hold slides in a reagent bath, and it suits school, college and laboratory-technician microscopy practicals. Supplied by Science Lab Supplies from Ambala, India, the jar can be quoted for schools, colleges, training institutes and distributors.
Specifications
The polypropylene Coplin jar is specified row by row in the table. In short, its grooved interior keeps up to 10 slides of 75 x 25 mm standing upright and separated, and the cap's built-in seal ring closes the jar leak-proof, so a reagent can stay in it between sessions.

Applications and Experiments for the Coplin Jar
The jar can be used to move slides through a staining sequence of fixative, stain, water rinse and alcohol. It suits Class 11–12 biology slide preparation, B.Sc. botany, zoology and microbiology staining practicals, and laboratory-technician training where several smears or sections are stained together in one run.
- Class 11–12 biology: staining onion root-tip squash or peel slides in batches of up to 10, before mounting them under Glass Cover Slips.
- B.Sc. practicals: safranin or Giemsa staining runs using solutions from the Microscopy Chemicals Set.
- Holding slides in fixative or buffer between sessions, with the sealed cap closed.
- Technician training: one jar per reagent, labelled and set out in staining order.
Alcohols used in staining are flammable and some stains irritate skin, so label each jar, keep flames away and wear gloves.
Standard Scope of Supply
The supply is one polypropylene Coplin Jar with its sealing cap, taking up to 10 slides of 75 x 25 mm in its grooved interior. Stains, slides and staining racks are separate catalogue items, and any of them can be added to the same quotation when a full staining bench is being equipped.
Packing, MOQ and Lead Time
Staining benches use several jars, one per reagent, so ask for a quotation for the exact number required, from one jar to sets for each practical group. Science Lab Supplies replies with the packing, delivery time and price, and slides, racks or stains can be quoted on the same document.
Holding an Importer-Exporter Code, Science Lab Supplies is in a position to ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Send the jar count via the contact page, add jars to the enquiry cart with your staining list, or go to the lab tender page for bulk tenders.
Frequently Asked Questions
How many slides fit in the Coplin Jar?
It holds up to 10 microscope slides measuring 75 x 25 mm. The grooved interior keeps each slide upright in its own slot, so neighbouring slides do not touch while they sit in the stain.
Will the jar leak if it is knocked over?
The cap has a built-in seal ring that makes the polypropylene jar leak-proof when closed. Even so, keep jars upright on the bench and close the cap firmly after each use.
How does it compare with the glass-covered Coplin jars?
The Coplin Jar Staining and Coplin Staining Jar take 26 x 76 mm slides, 10 at a time, under glass covers that withstand stain and organic solvents; this jar is polypropylene with a sealing cap for 75 x 25 mm slides.
Can I buy the Coplin Jar directly from Science Lab Supplies?
Yes. The jar is a supplied item that Science Lab Supplies sources and dispatches from Ambala, Haryana. Schools, colleges and distributors receive a quotation stating packing and delivery time, with staining accessories added if requested.
