Plastic Jars

RANDHAWA GLOBAL Staining Coplin Jar and Glass Slide, ‎RG-22001 (Pack of 8 Pcs) is a small, rectangular or cylindrical container, typically made of glass or plastic, with a tight-fitting lid or cover.
It is used to hold and immerse biological specimens, such as tissue sections or cells, in staining solutions to impart color and enhance contrast for microscopic examination.
The Coplin jar allows multiple slides to be stained simultaneously, making it a time-efficient tool in histological and cytological preparations.
The lid prevents evaporation of the staining solution and minimizes exposure to fumes or hazardous chemicals.
To use a staining Coplin jar, specimens are placed on glass slides and arranged vertically within the jar. The jar is then filled with the staining solution, which can be a dye or stain specific to the intended observation.
After a specified staining duration, the slides are removed, rinsed with distilled water, and then typically counterstained or dehydrated before being covered with a glass cover slip for microscopy.
Glass Slide:
A glass slide, also known as a microscope slide, is a small, thin, rectangular piece of glass typically measuring about 1 inch by 3 inches (25.4 mm by 76.2 mm).
It serves as the platform for mounting and viewing specimens under a microscope.
Glass slides are designed to be optically clear, allowing light to pass through the specimen for microscopic examination.
One side of the slide is flat and smooth, providing a stable surface for specimen placement, while the other side is often slightly frosted or marked for labeling and identification.
Specimens are typically affixed to the slide using mounting media, such as water, glycerin, or a specialized mounting medium, to ensure the specimen remains in place during microscopic observation.
Cover slips, also made of glass, are often placed over the specimen to protect it and provide a flat, uniform surface for the microscope objective to focus on.
Glass slides are commonly used in histology, cytology, microbiology, and various other fields of microscopy for the preparation and examination of specimens, such as tissue sections, blood smears, and microorganisms.
In summary, a staining Coplin jar is a container used for staining biological specimens, while a glass slide is the platform for mounting and viewing these specimens under a microscope. Together, they are integral tools in histological and microscopic studies, enabling the preparation and examination of samples for research, diagnosis, and education in the biological sciences.

The HTLP Polycarbonate Anaerobic Culture Jar HTLP-089 has a wide mouth that allows easy access to its contents. The colorless and odorless jar is made of polycarbonate, which prevents it from being scratched by the objects inside. It also retains its transparency even when used repeatedly. This material also has a high resistance to thermal shock and can withstand chemical corrosion and UV radiation, making it very durable.When you take a step back and look at microbes, you can't help but be impressed by how small they are. Microbes are so small, in fact, that it's often difficult to tell whether the thing you're looking at is alive or dead. In order to make sure that your cultures are growing properly and that they aren't contaminated with other bacteria, it's important to keep track of these microbes. This is a great tool for making sure that your microbes are safe and healthy. It features an anaerobic seal that keeps out harmful oxygen, meaning that no matter what conditions your cultures are exposed to, they'll still be safe in this jar. This particular model also has a wide mouth and large opening which makes taking samples as simple as pulling off the lid.This particular container is great for bacteria samples but is equally appropriate for storing food items such as yogurt or kefir. The high-quality polycarbonate material will ensure that the item can stand up to years of use without fading or breaking down. In fact, the unique construction of this container will allow you to store any liquid or semi-liquid food product without worrying about leakage or contamination by other bacteria.

RANDHAWA GLOBAL Staining Coplin Jar for Holding 5-10 Microscopic Slides, RG-3401 (Pack of 12 Pcs) is a laboratory container specifically designed for staining biological specimens, typically in histology, microbiology, and other biological research and diagnostic applications. Staining is a common technique used to enhance the visibility and contrast of cells and tissues under a microscope. Coplin jars provide a convenient and controlled environment for staining slides or tissue sections.
Key features and functions of a staining Coplin jar:
Design: Staining Coplin jars are usually made of clear glass or durable plastic and have a square or rectangular shape. They are typically open at the top to allow easy placement and retrieval of slides.
Compartments: These jars typically feature multiple compartments or slots, each designed to hold one or more microscope slides vertically. The compartments ensure that the slides are immersed in the staining solution and prevent them from sticking together during the staining process.
Lid: A lid or cover is provided to seal the staining Coplin jar, preventing the evaporation of staining solutions and minimizing exposure to potentially hazardous chemicals. The lid also helps maintain a consistent temperature if the jar is placed on a hot plate or water bath.
Chemical Resistance: Staining Coplin jars are resistant to a wide range of chemicals commonly used in staining procedures, ensuring that they can safely contain various staining solutions without degrading or leaching chemicals.
Graduated Scales: Some Coplin jars feature graduated scales on the sides, allowing users to measure and pour staining solutions accurately.
Applications of staining Coplin jars:
Histochemistry: These jars are essential tools in histochemical staining procedures used to visualize specific chemical components within cells and tissues, such as proteins, enzymes, and nucleic acids.
Microbiology: In microbiology, staining Coplin jars are used for bacterial staining techniques like Gram staining, acid-fast staining, and capsule staining.
Cytology: Cytologists use these jars for staining cytological specimens, such as Pap smears, to detect abnormal cell changes indicative of diseases like cancer.
Immunohistochemistry: Immunohistochemical staining of tissue sections to identify specific antigens relies on staining Coplin jars to apply reagents like antibodies and chromogens to slides.
Special Stains: Staining Coplin jars are used for various special stains that highlight specific cell components or pathological changes in tissues, aiding in disease diagnosis.
In summary, a staining Coplin jar is a specialized laboratory container designed to facilitate the staining of microscope slides and tissue sections. It provides a controlled environment for immersing slides in staining solutions, ensuring that biological specimens are properly prepared for microscopic examination. These jars are crucial tools in histology, microbiology, and other biological disciplines, contributing to the accurate diagnosis and research of diseases and cellular structures.
