Description
Scientific Instrument Services has redesigned the VG direct probe ceramic probe tip which holds the sample vials in place on the end of the probe. The VG originals were two pieces (VG #7025102 and #7050203). These were machined from soft MACOR ceramic. We have changed this to a one piece design for simplicity and ease of use. We have a hard alumina ceramic version, and a Vespel® type. The vespel is more durable, however, the heat transfer is not as good.
