Surface Coils for High-Field MRI/NMR

• Doty surface coils feature conductor geometries optimized for the best sensitivity
  and B₁ homogoneity with biological samples.
• Non-magnetic sealed tuning capacitors mounted adjacent to the coil on a low-    
  loss dielectric substrate – either polyimide or teflon.
• Fitted with double-shielded flexible rf line (Teflon or polyethylene) with BNC
  connector.
• Passive or Active Detuning for homonuclear experiments using a volume transmit coil.
• Double-tuned surface coils are also available.
• Coils will be covered unless ordered as uncovered.
• A Remote Coil Matching Network (RCMN) is required for use with the surface coils.
  The RCMN (which functions over a range of frequencies) can often be used for several coils. See description below.
  
  

Standard coil diameters currently include 8, 12, 16, and 24 mm.
Other sizes are available on special order. Please specify type, diameter, frequencies, and dielectric materials. Balanced circuits are used except for small coils at low frequencies. The prices shown are typical for fd (frequency x diameter) of 7 MHz*m or less, as for example, 24 mm @ 300 MHz. For fd greater than 7 or for non-standard sizes, prices are higher.
