Wizard Tube 
The Wizard™ Classic line of random sparse matrix screens is designed to increase your probability of producing crystals during the coarse screening phase when crystallizing biological macromolecules (proteins, nucleic acids, peptides, and combinations thereof).
The Wizard Classic reagents are proven to be a highly effective starting point in the screening of biological macromolecules. The Wizard Classic formulations include a large range of crystallants, buffers, and salts covering a broad range of crystallization space at pH levels from pH 4.5 to pH 10.5.Choose from Wizard Classic 1, 2, 3, or 4 non-overlapping formulations in matrix blocks or tubes.

Wizard Cubic LCP
The tools in the Wizard Cubic LCP (lipidic cubic phase) Kit enable researchers to prepare LCP-type crystallizations by hand. Ideal for low-protein experiments: effective protein volume for a single crystallization experiment is about 80 nanoliters. Wizard Cubic LCP Kit tools work especially well when traditional methods have failed to yield crystals. Lipidic cubic phase has worked well for the crystallization of 7TM membrane proteins (proteins with seven transmembrane helices). Four out of six GPCRs (G-protein coupled receptors), an important membrane protein class, and several microbial 7TM proteins have been crystallized using the LCP approach.

CRYO (I、II)
The Wizard Cryo™ line of random sparse matrix screens is designed for scientists who want to avoid the additional step of optimizing a cryoprotectant condition. Every Wizard Cryo formulation flash-freezes to a clear, amorphous glass in liquid nitrogen or in a cryo-stream at 100K. Crystals can be frozen directly from their growth drops, avoiding the additional step of pre-equilibration with an artificial cryo-condition that can damage the crystal. Eleven different cryocrystallants and sparing use of glycerol ensures a broad sampling of possible cryo conditions. Choose from Wizard Cryo 1 or 2 formulations in tubes or Wizard Cryo 1 and 2 together in a 96-well matrix block.

Hampton Siliconized Glass Cover Slides

ApplicationsHanging, sitting or sandwich drop crystallization
FeaturesHigh purity of glassSiliconized, hydrophobic glass surface0.22 mm & 0.96 mm glass thicknessThicker glass slides preserve temperature longer12 mm, 18 mm, & 22 mm glass diameterCircle & squareUV Compatible (>85% transmission)
12 x 0.22 mm Circle
18 x 0.22 mm Circle
22 x 0.22 mm Circle & Square

Description
Siliconized glass cover slides allow a droplet to be suspended in a position which provides near optimal conditions for vapor diffusion with the surrounding reservoir solution. These siliconized glass cover slides provide a consistent, high quality finish for crystallization experiments. The hydrophobic surface produces a drop which “stands well” and does not flatten on the glass. The siliconized surface prevents the adhesion of crystals and precipitate onto the glass surface. Use Dow Corning Vacuum Grease (HR3-510), Dow Corning 7 Release Compound (HR3-508), or immersion oil to seal cover slide to plate. Available in 12, 18 or 22 mm diameter circles and 22 mm diameter squares. Available in 0.22 mm or 0.96 mm glass thickness. The 0.96 mm thick slides are virtually unbreakable during crystallization handling.

The following slides are UV transmissable (>85%):
HR3-277 and HR3-279 – 12 mm x 0.22 mm Siliconized circle cover slides
HR3-231 and HR3-233 – 22 mm x 0.22 mm Siliconized circle cover slides
HR3-239 and HR3-241 – 18 mm x 0.22 mm Siliconized circle cover slides
HR3-215 and HR3-217 – 22 mm x 0.22 mm Siliconized square cover slides

Hydrophilic glass surface
Circle & squareDescription
Plain, non-siliconized, hydrophilic glass cover slides. Useful for hanging drop, sitting drop, and sandwich drop vapor diffusion crystallization methods. The hydrophilic surface creates a drop which is more flat than a drop on a siliconized surface. This offers enhanced imaging for very small drops. Use Dow Corning® Vacuum Grease (HR3-510), Dow Corning® 7 Release Compound (HR3-508), or immersion oil to seal cover slide to plate.HR3-209T 12 mm Plain circle cover slides for Tecan robot 5 oz case (~2,400 slides)

PEN-VAC Kit
ApplicationsHolding and manipulating small, flat surfaces such as glass cover slides
FeaturesSelf-contained vacuumNo power neededCompactDescription
PEN-VAC is a great tool for handling small, flat surfaced objects such as plain and siliconized cover slides, as well as plastic slides. Simply depress the side button, touch the tip to the object to be lifted and release the button. PEN-VAC creates a totally self-contained vacuum that lifts up to 50 grams for up to one minute. Less than an ounce, the lightweight aluminum body fits in a pocket. No power supply needed. The kit includes one PEN-VAC with 5 3/4″ blue body, (3) angled and (3) straight probes with (2) each 1/8”, 1/4”, 3/8” diameter blue silicone vacuum cups . It is packaged in a clear plastic storage case.
