The fully automatic Consolidated SSR and SR series of sterilizers are intended for use by facilities to sterilize heat and moisture stable materials by means of pressurized steam. These .An Autoclave Operator is responsible for operating and maintaining autoclave machines, which are used to clean and sterilize medical instruments and supplies. The Operator must ensure that the equipment is properly set up, operated, and maintained in accordance with applicable .

The only refractometer designed to "spot" read cabochons or small facets with diameters less .1 Use polarizing filter While you have a clear reading on a stone following the previous directions, unscrew the polarizing filter and place onto the eyepiece.The only refractometer designed to "spot" read cabochons or small facets with diameters less than 1mm. Top of the line desk model with removable eyepiece magnifier that enlarges RI scale image. Hinged lid protects glass working area from dust .Read this section thoroughly before you begin using the GIA Polariscope. The GIA Polariscope has two polarizing filters: the polarizer at the bottom and the analyzer at the top. The polariscope also includes a removable sample plate to hold the gem material, a removable 4X magnifier, an optic figure sphere, a power cord and a universal plug .

The lens has a polarizing filter that can be rotated. Both the filter and the lens are removable. The gem’s shadow is directed to the scale, and the RI is read where the shadow line falls. Refractive Index Testing: the General Procedure. To measure the RI of a faceted gem with a refractometer: For every rotation reading, take two measurements: one with the polarizing filter in North-South position and one with the polarizing filter in East-West position. The readings in the images below indicate a single refractive (isotropic) stone with RI .

Holding the polarization filter between you and the floor, look through the filter at a reflected light strip in the floor about five feet in front of you. Turn filter until reflected light strip disappears.Place the polarizing filter on the ocular and rotate it 90° back and forth (N-S to E-W). Does the shadow-line move? If it does not, rotate the stone 45° and rotate the polarizer back and forth again.

Premium Article - Membership Required. 738 Words, 3 Minutes of reading. The Duplex II and Rayner Dialdex both make excellent refractometers for gemologists. How do they compare head-to-head? Learn more from our review. Topics covered include: Ease of Use. Polarizing Filter. Finding the Shadow Line. Clarity of Readings. Refractive Index Readings.For every rotation reading, take two measurements: one with the polarizing filter in North-South position and one with the polarizing filter in East-West position. The readings in the images below indicate a single refractive (isotropic) stone with RI = 1.527, which is most likely glass.With the refractometer lens in place and the gem image's cutoff in view, put the polarizing filter in place. Rotate it a quarter circle or more while you watch the cutoff. If the band moves, you have a doubly refractive gem. If the band doesn't move, give the stone a quarter turn and test it again.1 Use polarizing filter While you have a clear reading on a stone following the previous directions, unscrew the polarizing filter and place onto the eyepiece.
