Manufacturing and Exporting of staining jars is done by Educational Instrument, which is a brand that produces the jar which is a lidded glass and plastic container that holds and immerses microscope slides in dye and reagent during the staining process. The staining jar is an important equipment in histology, pathology, microbiology and biology laboratories, allowing a number of slides to be kept together in the stain such that cell, tissue and microorganism can be seen through the microscope. This includes staining jars made from borosilicate glass and plastic, either in Coplin, Hellendahl and wide mouth style. These allow keeping of the slides in vertical and horizontal positions with a tightly screwed lid. This is meant for schools, colleges, universities and other industrial laboratories. Items are available on quotation and customization.

What is a staining jar used for?

The staining jar is used to hold the microscope slides in which the samples are dyed or exposed to different reagents, thus enabling the staining of an entire set of slides together without loss or contamination. This tool is utilized in histology, pathology, microbiology, and biology laboratories when preparing slides for investigation – emphasizing cell, tissue structure, and microbes.

Being constantly exposed to chemical dyes, the staining jar requires not only having good chemical resistance but also a proper lid and a surface that is easy to clean. The choice of its design mostly depends on the number of slides prepared at a time.

What types of staining jars are available?

Three common designs are offered: Coplin jars, Hellendahl jars and wide-mouth staining jars. They differ mainly in how slides are held — vertically or horizontally — and in how many slides each holds, so the right one depends on batch size and staining method.

Coplin jars suit small batches processed a few slides at a time; Hellendahl and wide-mouth jars suit larger batches or slides that need to stand vertically. Exact slide capacity and dimensions vary by design and are available on request.

Should you choose glass or plastic staining jars?

Choose borosilicate glass for chemical and heat resistance and clear visibility of the slides, and plastic where lighter weight and break-resistance matter more — for example in busy teaching labs. Both are offered in this range and both work with common laboratory dyes and reagents.

Glass is the usual choice for aggressive solvents and long immersion; good-grade plastic reduces breakage risk in high-throughput student use. Confirm the material against the specific stains and solvents in your protocol before ordering.

The JARS framework — a quick selection check

A simple, original checklist for specifying staining jars in a lab order:

• J — Jar design: Coplin, Hellendahl or wide-mouth, based on how slides are held (vertical/horizontal).
• A — Arrangement & capacity: how many slides you stain per batch — match the jar to your throughput.
• R — Resistance: borosilicate glass for chemical/solvent resistance; plastic for break-resistance; confirm dye/reagent compatibility.
• S — Seal & surface: tight-fitting lid to prevent evaporation and contamination, plus a smooth interior for easy cleaning.

Use JARS as the line-item spec when requesting a quote so the order matches your actual staining workflow.

Frequently asked questions

What is a staining jar used for?

A staining jar holds microscope slides while they are immersed in dyes and reagents, so a batch can be stained evenly and stored without evaporation or contamination. It is used in histology, pathology, microbiology and biology labs to prepare slides that reveal cells, tissue structures and microorganisms under the microscope.

What types of staining jars do you supply?

The range includes Coplin jars, Hellendahl jars and wide-mouth staining jars. They differ in how slides are held — vertically or horizontally — and in how many slides each holds, so the right design depends on your batch size and staining method.

Are staining jars available in glass and plastic?

Yes. Borosilicate-glass jars offer chemical resistance, heat resistance and clear visibility of the slides, while plastic jars are lighter and more break-resistant for busy teaching labs. Both work with common laboratory dyes and reagents.

How many slides does a staining jar hold?

Capacity depends on the design — Coplin jars suit small batches, while Hellendahl and wide-mouth jars hold more slides, positioned vertically or horizontally. Exact slide counts and dimensions vary by model and are available on request.

Are there lids on the jars to avoid evaporation? 

Yes. These jars will come with well-sealed lids or caps to ensure that the staining solution does not evaporate and to protect against contamination while using and storing. A smooth inner surface ensures that cleaning the jars is easy between the different protocols.

What are the staining protocols for which the jars can be used? 

The jars have been designed to function with laboratory chemicals and dyes for protocols like the Gram stain, acid fast stain, and hematoxylin & eosin (H&E).
