analytical hplc
Rheodyne ® Model 8125
Micro-Scale Injector
• Versatile!—Works with microbore (1–2mm i.d.) and
analytical (2–6mm i.d.) columns
• Low dispersion 0.25mm flow passages
• Built-in position-sensing switch
Rheodyne ® Model 7410
Micro-Scale Injector
• High volumetric precision
• 0.5µL to 2µL removable internal sample loops
• Designed for 1–2mm i.d. columns
The 8125 valve has unique “dual size” ports for tubing
connections. This allows either 1/16" o.d. or 0.02" o.d. tubing
to be used. Connections to 1/16" column endfittings are
facilitated with a connecting tube supplied with the valve.
The smaller flow passages also result in more resistance to
flow. This makes it harder to load large sample volumes. The
maximum recommended sample volume for the 8125 valve is
500µL. All sample loops are externally plumbed.

Rheodyne ® Model 7410 Sample Injection Valve is a single
mode injector whereby sample is loaded with the complete
filling method using a loop-filler port. This injector can be used
with Rheodyne ® loop-filler port accessories, position sensing
switches, and mounting panels.
The valve has four ports which are threaded to accept
Rheodyne ® male nuts and ferrules (compression-type tube
fittings) for 1/16" o.d. stainless steel tubing.
