AEROSPRAY® HEMATOLOGY SLIDE STAINERS
In a world where hype frequently outruns fact, the Aerospray® Hematology Pro or Stat Stainers have become dependable workhorses in labs all over the world, mature, proven systems with thousands of satisfied users who need exceptional cleanliness, quality and dependability at an affordable cost.

ELITech’s advanced approach to slide staining puts an end to costly and messy procedures. Microprocessor control and user-programmability bring substantial savings in time and reagent consumption. Since stain is never reused, cross-contamination of specimens is not possible.

ELITech’s Aerospray Stat (aqueous-based) or Pro (methanol-based) are excellent choices for peripheral blood smears, bone marrow, and other body fluids. The Aerospray fixes, stains and dries up to 12 high quality slides in about 4 minutes with little or no debris or precipitation.

Not content to rest on its laurels, ELITech has continually upgraded the performance of both the Hematology stainers to be state of the art and a cut above the competition. And all Aerospray stainers are backed by excellent customer service and support.

Every Aerospray is also a full featured cytocentrifuge with the purchase of the optional Cytopro® Rotor.

• Reagent economy
Reagent is applied to individual slides as an atomized spray. Reagent delivery conforms to the number of slides being stained, saving reagent costs.

• No Cross-Contamination
Fresh reagents applied with each cycle.

• User-Programmability
With the Aerospray Stat you get a choice of 10 intensity settings, including 3 bone marrow settings. The Aerospray Pro is highly responsive to a wider range of stain settings to meet individual needs.

• Automatic Reagent Level Sensor
Sensors warn the user when it’s time to replace reagents.

• Convenience
An operator-initiated clean cycle reduces maintenance to a minimum. It’s a clean, no fuss process from start to finish.

• Rapid Performance
With a cycle time of less than 4 minutes, for the Aerospray Stat, or 5 minutes for the Pro, either stainer is ideal for STATS, but with throughputs of 145-180 slides per hour, they handle heavy loads easily. In either case, slides emerge dry and ready for the microscope.

• Optional Cytocentrifuge Rotor
For the cost of an optional Cytopro rotor, the Aerospray becomes a superb cytocentrifuge with 8-slide capacity and keyboard programmability at a fraction of the cost of a stand-alone cytcentrifuge.

Answering Today’s Laboratory Needs
In the face of rising health care costs, any capital outlay must return maximum benefit for every dollar spent. The pressures of tight budgets, productivity demands and the need for diagnostic integrity make investment in the Aerospray Hematology Stat or Pro Slide Stainer/Cytocentrifuge a choice that will please both the medical technologist and the laboratory administrator.

CYTOPRO® CYTOCENTRIFUGE
Cytopro sets the standard for consistent performance and convenience in a cytocentrifuge. With the help of experienced laboratorians, we designed and built a cytocentrifuge that puts unsurpassed ease of use, and maximum flexibility and safety at your command.

The patented Cytopro is a complete, integrated system including an instrument console with touch pad controls and an eight-station cytocentrifuge rotor. The ELITech sample chambers are the heart of the Cytopro system. Their unique, well thought out design ensures superb cell recovery and adherence without intricate error-prone procedures. In other words it works like a dream!

Perfect Alignment
The Cytopad® snaps quickly between the chamber and the frame. This guarantees that the pad is always correctly aligned with the sample tunnel. No fumbling and no cell loss due to poor alignment.

Patented Flow Control Ring
The Cytopad features a controlled compression ring around the sample hole. This controls the rate of absorption and allows compensation for the lot-to-lot variations in paper quality for more consistent results.

Dual Sample Ports (single chamber only)
Two ports, one in the sample well and one in the tunnel, provide sample treatment versatility, allowing you to introduce pre-wetting fluids and making in situ fixation easy and reliable.

Chamber Caps
You can load samples directly through the chamber caps to prevent spilling of hazardous samples. Caps provide added safety to the operator.

7 mm Cell Area
A large, centered cell deposit area makes screening easier and more sensitive.

Dual Sample Chambers
Advanced design places two samples on the same slide for increased efficiency and economy. Dual sample chambers provide the same excellent results as our single sample chambers.

How the Chamber Works

1. The cell suspension is pipetted into the sample well or the tunnel.
2. As the rotor starts spinning, centrifugal force moves the suspension towards the slide.
3. Cells sediment onto the slide as the Cytopad absorbs the suspension medium.

Versatility is one of Cytopro’s major strengths. The system satisfies a wide variety of sample treatment requirements.

Choice of Absorption Pads
Cytopads come in two absorption speeds that are color-coded for ease of use. The white pad is for faster absorption of thick or debris-filled suspension fluids. The tan pad is for slower absorption of thin fluids such as cerebral spinal fluid (CSF). Where slower flow enhances cell recovery.

Disposable/Reusable Chambers
ELITech’s unique Cytopro chambers are competitively priced for disposal after use or they can be reused after suitable cleaning. The choice is yours.

Prewetting Versatility
The tunnel port accepts saline or other fluids to pre-wet the absorption pad at the beginning of a cycle. This exclusive patented feature significantly improves cell recovery.

In Situ Fixation
A common problem with Papanicolaou staining is air-drying of the sample cells. In situ fixation during the cytocentrifugation cycle is the most effective way to prevent this problem.

In situ fixation with Cytopro is very simple. Load a few drops of sample into the tunnel port, then load fixative into the sample well. As the rotor accelerates, the cells are fixed after they sediment onto the slide.

VAPRO® VAPOR PRESSURE OSMOMETER
No other vapor pressure osmometer has the credentials of ELITech’s Vapro,®(manufactured by Wescor, an ELITech group company). Since 1973 when Wescor introduced its first vapor pressure osmometer, this method has proven itself in thousands of laboratories and myriad applications. Our customers have rendered a clear verdict—vapor pressure osmometery is superior to all other methods.

“Vapor pressure measurement is the fastest and easiest method of determining osmolality, and the thermodynamic limitations of vapor pressure osmometry are least restrictive. For these reasons, vapor pressure osmometry is the method of choice for most fluids in biology and medicine in which water is the solvent.1”

The fundamental advantages of vapor pressure osmometry are now embodied in the most intelligent osmometer ever developed. ELITech’s Vapro Osmometer offers an intuitive approach that frees you from intensively “managing” an instrument.

Why Vapor pressure?
The Vapro method determines osmolality at room temperature with the sample in natural equilibrium. This precludes cryoscopic artifacts due to high viscosity, suspended particles or other conditions that can interfere with freezing point determinations, giving Vapro a much broader range of error-free applications.

Self-Cleaning Thermocouple and Easy Calibration
With the Vapro osmometer, say goodbye to intricate manual cleaning procedures. Vapro software monitors thermocouple cleanliness and the automatic Clean Cycle cleans the thermocouple when needed. The Vapro is self-calibrating and exceptionally stable. Calibration is verified using osmolality standards. If calibration becomes necessary the calibration function is performed and verified by the instrument.

ELITech osmometers have an unrivaled reputation for reliability. This is backed by ELITech’s strong commitment to customer service. You will always find the help you need from our knowledgeable and friendly service professionals.


How it Works
In most solutions, changes in concentration are accompanied by linear and proportional changes in the cardinal colligative properties of the solvent-vapor pressure, freezing point and boiling point. Measuring any of these properties provides an indirect indication of osmolality, but among them, only vapor pressure can be determined without a forced change in the sample’s physical state.

In the Vapro osmometer, vapor pressure is determined thermometrically by a fine wire thermocouple suspended in a small vapor space above the specimen in a sealed sample chamber. During a measurement cycle, the thermocouple undergoes a series of microprocessor-controlled temperature changes.
