This dissecting tray offers a lightweight and portable option for dissections where a wax base isn’t needed. Here’s a breakdown of its features, functionalities, and applications:

Material:

• Made of plastic, providing a lightweight, cost-effective alternative to metal trays.

No Wax Base:

• Similar to the GI sheet tray, this one lacks a wax base for securing specimens. This eliminates concerns about wax residue interfering with dissections or specimen preservation techniques.

Features:

• Size: This specific tray is a compact size at 12.5″ x 9″ x 2.5″ (approximately 31.75 cm x 22.86 cm x 6.35 cm).
• Shallow Design: The shallow depth (2.5″) keeps specimens easily accessible during dissections.
• Color: Colors can vary depending on the manufacturer, but black or white are common options for dissecting trays.

Functionalities:

• Holding Specimens: The tray provides a stable platform for holding small to medium-sized specimens during dissection procedures.
• Containing Dissection Materials: It can hold dissection instruments, fluids, and other materials needed for dissections.
• Collecting Dissection Waste: The tray can be used to collect waste tissues or fluids generated during dissection.

Applications:

• Dissections in Biology Labs: Suitable for dissections of smaller plant and animal specimens in classrooms and laboratories.
• Dissections Requiring Mobility: The lightweight and portable design makes it convenient for situations where mobility is necessary, such as field dissections.
• Student Use: A practical and affordable option for student use in biology labs.

Advantages:

• Lightweight and Portable: Easy to carry and maneuver during dissections.
• Cost-Effective: A budget-friendly option compared to metal trays.
• Easy Cleaning: The smooth plastic surface allows for easy cleaning and disinfection after use.
• No Wax Residue: Eliminates concerns about wax residue interfering with dissections or specimen preservation.

Considerations:

• Durability: Plastic trays might not be as durable as metal trays, especially with repeated use.
• Size Limitations: The smaller size might not be suitable for dissecting larger specimens.
• Securing Specimens: Without a wax base, some techniques for securing specimens during dissection might need to be adapted. Pins or other methods might be necessary.

Overall:

A plastic dissecting tray without wax (12.5″ x 9″ x 2.5″) is a practical choice for dissections of smaller specimens in laboratories and classrooms. Its lightweight design, affordability, and lack of a wax base make it a convenient option for various situations. However, consider the size limitations and potential need for alternative specimen securing methods when choosing this type of tray.
