Coplin jars (PVC) are laboratory containers used for storing, examining, and staining microscope slides and other specimens. They are often made of polypropylene, a durable, chemically resistant, and inexpensive plastic. Coplin jars can be rectangular or cylindrical in shape, with a tight-fitting lid and multiple wells on the lid for holding specimens or slides.
Coplin Jar PVC
The main function is to hold microscope slides vertically during various staining procedures in fields like:
-
Histology: Staining tissue sections (e.g., routine H&E stain, special stains).
-
Pathology: Preparing slides for diagnosis.
-
Microbiology/Hematology: Staining blood smears or bacterial samples.
-
-
Material: It is usually made from a chemically resistant and durable plastic like Polypropylene (PP) or High-Density Polyethylene (HDPE).
-
Advantages of Plastic: Unlike glass jars, plastic versions are unbreakable and are often suitable for:
-
Microwave applications (for antigen retrieval protocols).
-
Autoclaving (sterilization with heat and pressure).
-
-
Lid: It comes with a screw cap (often domed or shallow-threaded) that provides a secure seal to prevent contamination and minimize the evaporation of the staining solutions.
