A Guide to Choosing the Right Material
Glove box gloves are an essential part of many controlled handling and containment systems, allowing operators to safely handle materials inside an enclosed environment without compromising the integrity of the glove box.
They are widely used across industries including nuclear, pharmaceutical, medical, research and life sciences, where protecting the operator, the process or both from contamination can be critical.
Choosing the right glove box glove is therefore about considerably more than finding the correct size. Different glove materials offer different levels of chemical resistance, mechanical strength, flexibility, permeability and resistance to environmental conditions.
In this guide, we look at the main types of glove box gloves available and some of the factors to consider when choosing the right glove for your application.
What are glove box gloves?
Glove box gloves, sometimes referred to as dry box gloves or gauntlet gloves, are designed to be fitted to glove ports incorporated into a glove box, isolator or similar containment system.
Rather than wearing the glove in the conventional way, the glove remains attached to the glove port. The operator inserts their hands and arms into the gloves from outside the enclosure, allowing materials and equipment within the controlled environment to be handled without direct contact.
Depending on the application, this arrangement can help protect the operator from potentially hazardous substances, protect sensitive materials from external contamination or provide protection in both directions.
Where are glove box gloves used?
Glove box systems are used wherever materials need to be manipulated within an isolated or controlled environment.
Applications can include nuclear facilities, pharmaceutical production, laboratories, medical and life science environments, research establishments and other specialist industrial processes.
The requirements of these environments can vary significantly. A glove suitable for one application may not provide the chemical resistance, permeability, dexterity or durability required for another.
This makes glove material selection particularly important.
What materials are available for glove box gloves?
There are several materials commonly used for glove box gloves. Each provides a different balance of protection, flexibility and resistance.
Neoprene glove box gloves
Neoprene, or polychloroprene, provides a useful balance between protection, flexibility and precision, making it a versatile material for glove box applications.
It offers good resistance to a range of substances and is resistant to sterilisation processes including hydrogen peroxide and Gamma and Beta radiation.
These characteristics can make neoprene suitable for applications where dexterity needs to be combined with reliable protection.
MIP supplies neoprene glove box gloves for a range of circular and oval glove ports.
Latex glove box gloves
Natural latex offers excellent flexibility and precision, making it particularly useful where the operator needs a high degree of dexterity.
Latex also provides resistance to alcohols, reducing acids and diluted bases.
Its combination of flexibility and relatively low cost can make latex an effective option for suitable applications, although the chemicals and processes involved should always be considered before selecting a glove material.
Butyl glove box gloves
Butyl gloves provide excellent resistance to a range of chemicals as well as ionising radiation, ozone and ultraviolet exposure.
One of the notable characteristics of butyl is its high gas impermeability. It also maintains flexibility and grip at relatively low temperatures.
These properties can make butyl particularly useful within specialist containment environments where permeability and chemical resistance are important considerations.
Nitrile glove box gloves
Nitrile gloves combine chemical and mechanical protection with good flexibility.
Depending on the glove specification, nitrile can provide a textured grip and antistatic properties, making it suitable for a variety of controlled handling environments.
Nitrile glove box gloves are commonly encountered within chemical, pharmaceutical and medical applications.
CSM glove box gloves
CSM gloves, sometimes known by the trade name Hypalon, offer excellent resistance to oxygen, ozone, ultraviolet exposure, heat and a variety of chemicals.
They can be particularly suitable when handling oxidising products, concentrated acids, ammonia, concentrated alkalis and alcohols.
CSM also provides good mechanical resistance while retaining flexibility and dexterity, making it suitable for demanding nuclear and life science applications.
EPDM glove box gloves
EPDM, or Ethylene Propylene Diene Monomer, provides strong chemical resistance alongside good mechanical properties.
It also offers good resistance to many disinfectants used within pharmaceutical environments.
Depending on the specification, EPDM gloves can provide electrostatic dissipative properties, making them suitable for applications where electrical conductivity needs to be considered as part of the glove selection process.
How do you choose the right glove box glove material?
There is no single glove material that is suitable for every glove box application.
When selecting a glove, several factors should be considered.
Chemical resistance
The substances being handled are one of the most important considerations.
Different glove materials react differently when exposed to acids, alkalis, solvents, oxidising agents and other chemicals. The glove material should therefore be assessed against the specific substances and concentrations involved in the application.
Permeability
Where gases or vapours are involved, permeability may be particularly important.
Materials such as butyl can be selected for applications requiring particularly low gas permeability, but suitability will depend upon the individual process and substances involved.
Mechanical protection
The physical demands placed on the glove should also be considered.
Applications involving repeated handling, equipment or potentially abrasive materials may require different mechanical properties from applications primarily involving delicate laboratory work.
Dexterity
Greater protection is not always the only objective.
Operators may need to manipulate small components, instruments or samples within the enclosure. The thickness, flexibility and construction of the glove can therefore have a significant impact on usability.
Radiation and sterilisation
Nuclear, pharmaceutical and medical environments may expose gloves to radiation or sterilisation processes.
Where this applies, the selected glove material needs to withstand the relevant process without compromising its protective properties.
Glove port size and compatibility
The glove must also be compatible with the glove port onto which it will be fitted.
MIP supplies glove box gloves for a variety of circular and oval glove ports, with different materials available for different port sizes.
Checking the existing glove port dimensions and fitting arrangement is therefore an important part of selecting a replacement glove.
Circular and oval glove ports
Glove boxes can use circular or oval glove ports depending on their design and intended application.
MIP manufactures a range of circular and oval glove ports alongside compatible gloves and accessories. Standard sizes are available, while bespoke glove ports can also be manufactured where a project requires a different specification.
Ensuring compatibility between the glove, port, retaining system and enclosure is essential to maintaining a secure installation.
When should glove box gloves be replaced?
Glove box gloves should be inspected routinely as part of the maintenance procedures for the containment system.
Signs such as cracking, deterioration, loss of flexibility, punctures or other visible damage can indicate that replacement is required.
Replacement schedules should reflect the glove material, frequency of use, substances being handled, environmental conditions and any applicable safety procedures.
Where the glove forms part of a safety critical containment system, the relevant inspection and maintenance requirements should always take precedence.
