Slide strainer 

Wescor has developed a novel staining process for the methanolic Hematology stainer (U.S. Patent No. 6,058,432B2). Separate thiazin and eosin stains are blended in concentrated form, sprayed onto the specimen and partially evaporated by centrifugal airflow. This greatly accelerates staining and produces stains of superior quality. For dilute staining the blended stains are diluted with buffer. Wescor has become a world leader in staining technology during the past two decades. The company has steadily improved the groundbreaking Aerospray staining method with advancements in staining quality, user-convenience and cost reduction. Wescor continues to innovate and listen carefully to those in the Hematology community to improve Aerospray. The Model 7150 Aerospray is the result of this relentless search for excellence. Wescor has modified the traditional Romanowsky methanolic staining process with a unique mixing system that produces partially aqueous stains, while maintaining the advantage of separate storage of eosin and thiazin components. Aerospray employs centrifugal force to accelerate staining, and to dry the slides.
Simultaneous contact by both dyes produces the classic Romanowsky staining patterns with superior, textbook quality results. The Thiazin and eosin dyes are loaded separately onto the instrument to correct the reagent stability problems common with mixed stains. These stains are automatically mixed prior to application to produce superior results.
Aerospray offers a versatile selection of 9 different intensities for each of the 4 set programs: Rapid Wright- Giemsa, Wright-Giemsa, May-Grünwald Giemsa and Custom Stain with simple adjustment routines to tailor the staining to individual preference. A programmable function is also available for special staining requirements.
Fixation can be done in the instrument, or slides can be hand-fixed. While methanol is the normal fixative, Aerofix may be required in humid environments.
With the Aerospray you get up to 120 slides an hour and the convenience of cytocentrifugation in the same instrument.

Aerospray 7150 started stripping the slides this week-end. when I came in this morning noticed that Nozzle D was not sitting correctly in its place. when I removed it, it seems there is a plastic with a whom that came out of position from this nozzle. Any suggestion on how to fix it.Reply

  • Reagent Economy Reagent- is mixed together and then applied to individual slides in the carousel as an atomized spray. Reagent delivery conforms to the number of slides being stained on any given run. Consequently, stain consumption is conservative and reagent costs are significantly minimized.
  • Convenient- The Aerospray Stainer features user-selectable clean cycles that keep maintenance to a minimum. It's a clean no-fuss process from start to finish. Every Aerospray is also a fully capable cytocentrifuge with the purchase of the optional Cytopro® rotor. 
  • User-Programmability-The Aerospray is highly responsive to a wide range of staining requirements, with a choice of 9 preprogrammed intensity settings for the Rapid Wright Giemsa, Wright Giemsa, May Grünwald Giemsa, and Custom Stain programs. Simply make your selection by pressing a single keypad.
  • Rapid Performance-With a cycle time as low as 5 minutes, the Aerospray Stainer is ideal for STATS, but with a throughput of more than 120 slides per hour, it handles heavy loads easily. In either case, slides emerge dry and ready for the microscope.
  • Optional Cytocentrifuge Rotor- For the cost of the optional Cytopro Rotor, the Aerospray Stainer becomes a superb cytocentrifuge with 8-slide capacity and keyboard programmability-all at a fraction of the cost of a stand-alone cytocentrifuge.
