Amazon keyword : inoculation loop. Good for removing crystals from NMR tubes. To use dip loop in oil, insert into tube, spin loop to gather crystals then remove loop.
Amazon keyword : micro paint brush. Good for picking up small dry crystals.
NMR tube spatula
Wilmad-LabGlass: SST Microspatula, 250 x 3 mm for 5 mm NMR Sample Tube
Beale Spatula Wax Mixing Carvers Dental Double Ended Stainless Steel Lab Instruments
PET clear heat shrink medical tubing : Choose thin-walled tubes 0.5-0.25mm
#68 for 0.8-1.0mm, #78 for 0.5-0.8mm (pack powder in kapton/pet)
Oils and Grease (handy chart for viscosities)
STP oil treatment
Good cryo-protectant (does have a minor amount of anti-knock Zn additive ~5ppm) Comment : Buy STP brand name!
Use L. M or N
Fomblin YL VAC 25/6
perfluoropolyether vacuum oil
Krytox 205 GPL grease and 105 oil (see also LVCyro oils)
Krytox fluorinated oils are a series of low molecular weight, fluorine end-capped, homopolymers of hexafluoropropylene epoxide. The polymer chain is completely saturated and contains only carbon, oxygen, and fluorine; hydrogen is not present. Krytox GPL 105 oil and Kryto GPL 205 grease contain no additives.
Low form dewer can be used in mounting crystals with the microscope.
slides with cavities : comment : Good for holding samples covered by solvent.
Spot plates : Spot plate : comment : Good for growing crystals
Plastic Square Petri Dishes : good for holding slides (with crystals in oil). Can be compactly stacked with other square dishes.
Crystal Drying Tiles
Unglazed ceramic tiles
Use under side of tile to dry crystals. Place in freezer with xtals bring to low temperature and then transfer to microscope. Will keep crystals cool for about 3 mins.
Powder Sample holders and Sieves
Zero Background Holder (ZBH)
without cavity and/or with cavity Single Crystal Quartz Holder Mount in stainless Steel holder or use with back-loaders
Quartz disks are cheap powder sample holders. Sand blast surface to create a shallow divot.
100 mesh (150m) sieve
You can position a sieve over the ZBH, load a powder and gently tap, to produce a monolayer of dispersed powder on the ZBH surface.
Small Paint Brush
Use to sweep powder through sieve.
Floss Picks Fiber/tube diffraction remove floss and mount fiber
Micro Aligator Clips hold samples for wide angle scattering
SEM pin stub
SEM pin mount use for mount samples for powder diffraction on SCD instrument
#6 Roofing nails
: 2.5 cm to 4cm length (1 to 1.5 inch ) Copper or Stainless Steel. use for mounting samples for powder diffraction on SCD instrument
Ruby Spheres Alignment xtal. Not all spheres are single un-twinned crystals. Buy several and examine them one by one to find a single crystal.
Tool Box : Compartment Storage Organizer Box with Removable Dividers
Good tool kit for instrument maintenance. 113-Piece Tamper-Proof Bit Set
Good toolkit for maintanence jobs.
