Burette Stopcocks, PTFE Key, Straight Through
Product Code : JA-SCSAS-1658
Burette Stopcocks, PTFE Key, Straight Through (product code JA-SCSAS-1658) are the flow-control taps used on burettes. This burette stopcock has a borosilicate glass barrel and a PTFE key, which gives high resistance to chemical attack. The barrel is highly polished and the key is self-lubricating, so the stopcock turns smoothly without stopcock grease, which avoids grease contaminating titration results. Laboratories order them for new burettes and as spares for repairs.
Specifications
These burette stopcocks combine a highly polished borosilicate glass barrel with a self-lubricating PTFE key and a straight-through bore. No grease is needed, and PTFE resists attack by the acids, bases and solvents used in titration.
