Orion Electric

Apply the disciplines of biology chemistry and physics with the materials and procedures introduced in this activity. Several techniques used in forensics are covered and include the analysis of fingerprints soil hair documents and drugs and poisoning. It comes with enough materials for six setups and an instruction manual.

The Hair Analysis Kit provides students with an opportunity to learn important laboratory skills while studying the morphology of hair samples from various species.ﾠWritten materials include a discussion of hair as a tool of forensic science and illustrated descriptions on the structure of hair.ﾠA slide set provides additional instructions on characteristics of hair from various species.ﾠAfter the written and visual materials are discussed in class or studied independently students conduct two forensic examinations of hair samples by preparing whole hair mounts and scale casts standard procedures used by forensic examiners in crime laboratories. This kit is ideal for students grads 7-11. The materials in this kit are sufficient for 24 students working in groups of 6. Materials included:... Less

If the idea of a big-aperture telescope appeals to you, but the portability issue has kept you on the fence, you can hop off it now. We've got the perfect solution - the SkyQuest XX12i IntelliScope Truss Tube Dob. It's a deep-sky observer's dream scope, offering jumbo 12 Pyrex optics (f/4.9); a stylish, reduced-weight base outfitted with IntelliScope object location technology; and a sturdy truss tube design that disassembles in about a minute into compact, easily portable components. Finally, a deluxe, large-aperture Dobsonian that fits comfortably in a compact car for transport to your favorite observing site! The eight trusses (four captive pairs) provide more-rigid support than other designs in this category. We've also outfitted the XX12i base with nothing but the best materials:... Less

Powerful enough to split close double stars, resolve bright globular clusters, or look an eagle in the eye, Orion's Apex 102mm is both a fine astronomical instrument and an unparalleled terrestrial spotting scope. The Apex's 102mm-diameter (4) optics collect 28% more light than a 90mm scope. The fully multi-coated curved front meniscus lens guarantees the highest possible light transmission. The Maksutov- Cassegrain design collapses its 1300mm (f/12.7) focal length into a tube length less than 12 long. The Apex 102 tube easily pops on and off a telescope mount or camera tripod with the built-in 1/4-20 adapter plate, and doubles as a high-power telephoto lens. Just mount a 35mm camera body (with T-ring sold separately) to the T-threads on the eyepiece holder and you're set! Includes 25mm... Less

21CFR11 Software Version 2.0 for 3-, 4-, and 5-Star Series meters. Instruction manuals for the Star Series are available in three formats.

With a tube length of 11 inches, a 90mm (3.5) precision- polished fully multi-coated meniscus front lens, and solid uncompromising construction. the Apex 90 Compact Mak is a paragon of portability, optical excellence, and durability. Better still, it's one of the most versatile scopes we offer. The Apex 90 delivers bright, high-contrast images, and with a focal length of 1250mm (f/13.9) you also get a generous image scale. It features a built-in 1/4-20 adapter plate that makes it easy to mount onto a standard photo tripod for viewing grand daytime vistas. Attach a 35mm camera to the scope's visual back (with a T-ring adapter sold separately) and use the whole assembly as powerful telephoto lens for astrophotography and terrestrial shooting.
