Which material is commonly used for rodent cages and has better properties than polycarbonate?

• A. Polysulfone
• B. Polyethylene
• C. Polyvinyl Chloride
• D. Stainless Steel

Answer: (A)

Rodent cages need a material that can endure frequent sterilization, resist cleaning chemicals, and stay clear for easy observation. Polysulfone offers higher heat tolerance and stronger autoclavability than polycarbonate, so cages made from it can be autoclaved multiple times without cracking, clouding, or degrading. It also provides good chemical resistance, helping it withstand routine cleaning agents used in animal facilities. This combination of thermal stability, durability under repeated sterilization, and chemical resistance is why polysulfone is commonly chosen over polycarbonate. Stainless steel is very durable and autoclavable but less transparent and heavier, while other plastics may not hold up as well to repeated sterilization or maintain clarity.
