Nonreactive forceps/tongs?

[THX-1138]

I need some forceps or tongs that I can use to extract items from caustic solutions. E.g., pulling a circuit board from a etching solution, or something from an HCl bath.

 

They need to be pretty long, easily manipulated (i.e., closed and held closed) far from the tip, heat-tolerant, and reasonably non-reactive.

 

Any suggestions of what I can use and where I can get one?

 

Thanks!

I am not sure about the length you may need but for wafer etching I use these guys.

I'm thinking about 17-25cm, and with tips that can get a grip on odd shapes. What's a good non-reactive coating? Nickel? Teflon®? Maybe plastic 'tweezers' would do, if they're high-temp tolerant.. or hemostats..?

Teflon (PTFE) is quite good for use with corrosive substance (I use piranha solution, for instance), though nickel plating also works well.

From the same supplier as above:

But you may want to check out other clean room suppliers, for instance. Alternatives are the "generic" lab suppliers as VWR or Fisher.
