Hi,

I was wondering whether anyone can help me.
I am changing the needle seat in the LC1100. I wanted to know what size the black tube stood for? Is it 100micron?
Thanks Aman

What "black tube" are you talking about? The needle seat has tubing connected to the bottom (called the needle seat capillary), and that tubing is attached to the switching valve.

Hi aman,
Probably You have G1377A micro WP Sampler.
The black seat capillary is 100 micron, but you can identify by PN:
G1375-87317 (100 μm, 150 mm)
G1375-87316 (75 μm, 150 mm)
G1375-87300 (50 μm, 150 mm)
