Gibson Bioscience recalls KOH 10% solution (Cat. No. 300145) due to hydrogen peroxide contamination. This may cause unintended reactions during lab use. Affected lots include 21137116 with UDI 10634853000633.
A lot of KOH 10% was made with Hydrogen Peroxide 3% instead of KOH 10%.
Gibson Bioscience is recalling Potassium Hydroxide 10% solution (Cat. No. 300145) because some batches were contaminated with hydrogen peroxide instead of pure KOH. This could lead to unexpected chemical reactions during lab work, especially when handling biological samples.
The solution was made with hydrogen peroxide 3% instead of pure potassium hydroxide. This contamination could cause unintended chemical reactions, such as rapid oxidation or foaming, during lab procedures. However, the risk is low under normal lab conditions.
Lab technicians and researchers using the KOH 10% solution for fungal identification may be affected. Those handling the product without proper safety protocols are at slightly higher risk.
Check the lot number on the container, which should be 21137116 for this recall. The unique device identifier (UDI) is 10634853000633. This product is used for fungal identification in clinical labs.
Verify the lot number (21137116) and unique device identifier (UDI) 10634853000633 on the container.
The product was made with hydrogen peroxide 3% instead of pure potassium hydroxide, which could cause unintended reactions during lab use.
Check the lot number and UDI on the container. If it matches the recalled batch (lot 21137116, UDI 10634853000633), contact Gibson Bioscience for guidance.
The recall indicates a potential for unintended reactions, but the risk is low under normal lab conditions. Proper safety protocols should minimize any risk.
