Laboratory consumables are an important part of bacterial endotoxin testing. Even when the reagent and sample are properly prepared, endotoxin contamination from tubes, pipette tips or microplates can affect the final result.

Why Consumables Matter

Endotoxin-sensitive assays require careful control of all materials that come into contact with the sample or reaction mixture. Ordinary laboratory consumables may contain background endotoxin and therefore may not be appropriate for sensitive endotoxin testing.

Pyrogen-Free Pipette Tips

Pyrogen-free pipette tips are designed to minimize endotoxin contamination during liquid transfer. They are particularly useful when transferring samples, standards and reagents during endotoxin testing procedures.

Endotoxin-Free Tubes

Endotoxin-free tubes can be used for sample preparation, dilution, reaction and standard preparation. Properly processed tubes help reduce the possibility of introducing background endotoxin into the assay.

Pyrogen-Free Microplates

For microplate-based kinetic or chromogenic assays, the plate itself becomes part of the reaction environment. Pyrogen-free microplates and reservoirs help minimize contamination during automated or high-throughput endotoxin testing.

Controlling consumables is therefore an important part of a complete endotoxin testing quality-control strategy.
