Automated stainer for microscope slides
Microscope slides stainer — V-Chromer

Automation of slides staining

The use of automatic analyzers in laboratories hasn’t relieved personnel from the necessity of performing manual microscopic examinations of body fluids.

Correct staining is of vital importance for preparation of slides for microscopic examination. Manual staining process often does not carefully follow the staining protocol. As a result doctors obtain faulty slides with elements that are hard to discern even after the readjustment of the microscope.

V-Chromer automates slide staining procedure. One touch of a button provides evenly stained high quality slides suitable for manual examination or analysis using automatic analyzer.

Throughput of up to 100 slides per hour with minimal consumption of reagents

Stained slides
  •  Staining process automation and standardization
  •  Loading of up to 25 slides simultaneously
  •  Throughput of up to 100 slides per hour
  •  Minimal consumption of reagents
  •  Strict adherence to the staining protocol
  •  Easy to use and maintenance-friendly

V-Chromer significantly facilitates and enhances slide staining process

Personnel protection when working with stains

Personnel protection when working with stains

Stainer lid is tightly closed (1), charcoal filter (2) neutralizes evaporations and odor from stains (does not require an exhaust hood) and vessels with reagents (3) are only open when used. Laboratory personnel have minimal contact with stains and vapor discharges.

Autonomous system that does not require connection to water supply or drainage

V-Chromer does not require connection to water supply or drainage

There is no need to connect V-Chromer to water supply or drainage. Water is taken from a special tank and staining waste is gathered in a separate container. One pair of containers allows staining of 1000 slides.

Slide identification using barcodes

Поля для маркировки слайдов не окрашиваются

Top of the slides is not immersed into the staining reagent, which leaves the barcodes intact for identification.

V-Chromer operation principle

Vessels with stains

The rack with loaded unstained slides is successively immersed into the vessels with staining reagents according to the set protocol. The last vessel contains water where the slides are rinsed after staining. Once the staining process is finished, the rack moves to the first vessel for drying. All actions are performed at intervals according to the built-in timer. Once V-Chromer work is done you will obtain stained dry slides ready for examination.
