Yes, the following Vernier spectrometers can be used to assess DNA purity and concentration:

Go Direct® UV-VIS Spectrophotometer (GDX-SPEC-UV)
Vernier UV-VIS Spectrophotometer (VSP-UV)
Go Direct® Fluorescence/UV-VIS Spectrophotometer (GDX-SPEC-FUV)
Vernier Fluorescence/UV-VIS Spectrophotometer (VSP-FUV)

DNA has an absorption maxima at approximately 260nm. At 260nm, an A260 value of 1.0 is set for a pure solution of dsDNA with a concentration of 50 ug/mL.
