Description: M16/AR-15 Flip Up Single Plane Dual Aperture Rear SightRear sight attaches to M16/AR-15 flat top A3 upper receivers and may be used as a back-up rear sight or a lightweight rear sight to co-witness with red dot or holographic sights. Sight locks in its upright position, a spring loaded release must be depressed to place the sight in the down position. Sight has both 0.199 inch and 0.73 inch apertures on the same sighting plane. Allows both apertures to be sighted to the same point of impact. Sight has four apertures so that rotating the dial in either direction brings the next size aperture to view. Windage is adjusted using a standard A2 windage adjustment drum. One click allows 0.55 moa change on rifles and 0.65 moa change on carbines. Black.Additional Information:

Welcome to Aperture Laboratories, A Trusted Friend in Science! One of the many perks of working here is that Aperture provides all the human fuel you can drink. Human fuel, or "coffee" as it is often called, is available in break rooms throughout the lab. A quality human fuel receptacle can be acquired through the monkeys at ThinkGeek. Please do not use your Aperture Science Mug outside of designated areas, and please do not utilize your Aperture Science Mugs to ingest unsafe liquids or neurotoxins. Science Maybe you'll find someone else to give you coffee... maybe Black Mesa? (That was a joke, ha ha, FAT CHANCE!) Anyway, this coffee is great, so delicious and hot. But look at me still talking when there's science to do...

The Z series consists of three models of mercury-free analyzers, each of which allows for variable, user-specified cell size settings and the capability of analyzing virtually all cell types and species variations. All units use the Coulter Principle (Electrical Sensing Zone Method) of counting and sizing cells. This proven method ensures accuracy, speed, versatility, and reproducibility in all applications. Standard apertures are available in five sizes, and for very small sample volumes, ampule insertable apertures may be used. The Z1 Single Threshold model permits the setting of one size threshold. Cells equal to or larger than this setting will be counted. This unit is ideal as a fully automated instrument for the rapid enumeration of both tissue culture and blood cells, as well as obtaining rapid total cell counts on cell lines containing uniformly sized cells. The Z1 Dual Threshold model counts cells or particles in three regions of the population; above the lower size, between the lower and upper thresholds, and above the upper size setting. This is ideal when cell numbers between a selected size range are required. The Z1 Dual Threshold model is designed for platelet applications and for working with numerous cell types of variable sizes. Both Z1 instruments incorporate an oil displacement pump which delivers a high degree of accuracy and precision and eliminates the need for mercury. These units allow for absolute cell counts or concentration, storage of up to five analysis settings, and a constant current feature which eliminates calibration drift. Instruments are certified to ISO 90001 by NSAI Quality Assurance. The Z2 Dual Threshold model shares the features of the Z1 Dual Threshold model, but adds the enhanced dimension of providing accurate poulation size distribution data. The Z2 displays the entire size distribution graph or the size statistics and counts between user-selectable areas of the graph. This unit has the ability to average counts and

3M Ophthalmic Surgical Drape with Aperture Size: 15" x 15" - With adhesive around aperture 3M Ophthalmic Steri-Drape is a drape with aperture and is generally used for ophthalmic procedures. The drape that is made from clear polyethylene plastic with a matte finish and includes adhesive around the aperturep for secure adhesion. 3M Steri-Drape is available in a variety of sizes with different design features to meet the needs and surgery requirements of surgeons worldwide. Product Benefits: Reliable adhesive stays secure to help provide a sterile field. Adhesive film isolates the surgical site from lid margins, eyelashes and eyebrow to help reduce the risk of surgical site contamination. Drapes can be used for a variety of procedures. Drapes remove easily helping to decrease procedure and cleanup time. Aperture drapes have adjustable apertures that allow for custom fitting to each patient, helping to decrease inventory and cost of drapes. Product Applications: For use in all types of cataract, extraocular, intraocular and refractive procedures. Isolating lid margins and eyelashes from the surgical site. Draping off surgical site for minor office procedures. Product Specifics and Packaging Drape Size: 15" x 15" Peel-tape adhesive area: 3-7/8" x 4-7/8" Circle aperture size: 2-3/8" Drape is transparent Packaged in pouch containing 1 drape Box of 10 Pouches Case of 4 Boxes ( 40 drapes total)
