Q = What is a suitable wire gauge of Nichrome wire to use with needle holders for flame testing?
A = A suitable wire gauge would be 26 swg (0.46mm diameter) but a maximum gauge of 24 swg (0.56mm) should fit into the holders.
Q = What is the maximum diameter wire which can be used with the needle holder.
A = Typically, for flame testing, Nichrome wire 0.46mm dia. (26 SWG) or Platinum wire 0.25mm dia. (33 SWG) are used in conjunction with the needle holder. However, the maximum diameter wire which could be used is approx. is 0.56mm (24 SWG).
