Single-use screw cap containers, sealed and pre-filled with 4% buffered formaldehyde are designed to ensure maximum safety and practicality in the transport and storage of biological samples. With a capacity of 60 ml, these containers represent an ideal solution for laboratories, clinics, and research institutes that require an effective method for tissue fixation.

Main Features

• Capacity: 60 ml (35 ml of 4% buffered formaldehyde)


• Dimensions: Container with a diameter of 35 mm and a height of 70 mm


• Cap type: Screw cap for a secure and sealed closure


• Pre-filled: Ready to use, reducing the risk of operator exposure

Advantages of Using 4% Buffered Formaldehyde

4% buffered formaldehyde, also known as 10% buffered formalin, is one of the most widely used fixatives in histopathology. Its advantages include:

• Inactivation of autolytic enzymes and bacteria, preventing tissue putrefaction.


• Structural stability of the chemical constituents of protoplasm.


• Hardening of protein gels without separating water from proteins.


• Rapid penetration into tissues, ensuring effective fixation.

Instructions for Use

To ensure correct use of the containers, carefully follow the instructions:

Container with Screw Cap

1. Unscrew the cap and introduce the sample avoiding spillage of formaldehyde.


2. Replace the cap following the threading of the container correctly.


3. Screw tightly to ensure sealing.

Precautions during Transport

• Take all necessary precautions to avoid spills and shocks.


• Use a secondary container for transport (e.g., “Transbag” or “Securbox”).


• Always wear personal protective equipment (PPE) such as masks, gloves, and safety goggles.

Labeling and Safety

The containers are labeled in accordance with Regulation No. 1272/2008 of the European Parliament (CLP) and the UNI EN ISO 7010 standard (Biohazard symbol). It is essential to carefully read the information on the label, including risk and safety phrases, and consult the safety data sheet for information on hazards and precautionary measures to be taken.

Conclusion

Investing in single-use pre-filled containers with 4% buffered formaldehyde means ensuring a safe and effective method for the preservation of biological samples. Their innovative design not only facilitates the work of operators but also helps maintain high standards of safety and hygiene in laboratories.
