Types of Nuclear Glove Boxes

Standard Nuclear Glove Box

Standard nuclear glove boxes are widely used in laboratories where radioactive material handling is required. They are designed to create a sealed environment that protects operators from exposure. Features include integrated glove ports that allow for safe manipulation of materials without direct contact, minimizing contamination risks.

Lead Lined Glove Box

Lead lined glove boxes are specifically designed for the handling of radioactive materials in environments where exposure to ionizing radiation is a concern. These boxes are equipped with 5 mm lead shielding and lead glass windows to provide visibility while maintaining safety. They are ideal for radioisotope preparation and other applications where radiation shielding is critical.

Custom Engineering Glove Box

Custom engineering glove boxes cater to specialized nuclear projects, allowing for tailored designs that meet specific operational needs. These boxes often comply with stringent NQA-1 standards, ensuring high safety and quality levels. Custom solutions can address unique facility constraints or specific handling requirements.

Ventilated Glove Box

Ventilated glove boxes are designed for applications requiring high purity and controlled atmospheres. They incorporate advanced air filtration systems and may use inert gases, like nitrogen, to prevent unwanted chemical reactions. These features are essential in environments such as biotech and pharmaceutical labs, where maintaining a contaminant-free atmosphere is paramount.

Shielded Nuclear Glove Box

Shielded nuclear glove boxes provide enhanced protection against ionizing radiation. They feature thick lead shielding and secure transfer chambers that allow for the safe transportation of radioactive materials into and out of the glove box without compromising containment. These boxes are fundamental in nuclear medicine and research facilities.
