Offered for sale is a fine antique brass microscope slide ringing table. The instrument is in good working condition. This device was used to apply a ring of cement or glue or sealant to the slide and was commonly used to apply a finishing coat of varnish or ‘asphaltum’ as a ring sealing the edges of the coverslip. The instrument has some losses to the lacquer as would be expected for a used device of this type. When the knurled control knob is used to start the rotation, the rotation continues nicely based on momentum and the needle point support.
