Excell 22 Sheath Solution

Introduction Excell 22 Sheath Solution

The Excell 22 Sheath Solution produced by Labnovation is a highly sensitive and vital biochemical reagent supplied and distributed within the Iranian diagnostic market by Arya Tashkhis Pars.

Ensuring cell counting channel accuracy and guiding blood fraction hydrodynamics in 5-part differential devices require calibrated carrier products. Excell 22 Sheath Solution (also known as Sheath Fluid or carrier fluid), produced by the reputable Labnovation company, is a highly sensitive and vital biochemical reagent supplied and distributed within the Iranian diagnostic market by Arya Tashkhis Pars. Formulated in a standard 10-liter volume, this solution is specifically designed to comply with hydroforming protocols, fluidic systems, and optical lenses of the Excell 22 cell counter model, managing single-file cell passage past optical sensors with absolute precision.

Strategic Applications and Hydrodynamic Mechanism of Excell 22 Sheath Solution

Serving as the flowing fluid and transport matrix in the cell counter structure, this solution directs the following mechanical and optical processes:

• Creating Hydrodynamic Focusing: Forms a liquid sheath around injected blood samples to align blood cells (WBC and RBC) into a single-file stream for orderly passage through optical and laser reading zones.

• Continuous Optical Chamber Flushing (Flow Cell Flushing): Executes 3D flushing of tubing and flow apertures after each sample to remove cell debris and biofilms, preventing sample carryover.

• Guaranteeing Standard Refraction (Refractive Index Matching): The ultra-clear formulation delivers a stable refractive index to minimize laser beam scatter during WBC Differential measurements.

• Anti-Bubbling Mechanism: Contains surface-tension-reducing compounds to prevent micro-bubble formation, which instruments might misinterpret as blood cells.

Technical Specifications and Device Compatibility

Quality Features and Operational Benefits of 10-Liter Containers

• Optimal Volume for High Workloads: The 10-liter container reduces reagent replacement frequency in high-traffic laboratories, maintaining hydraulic calibration stability.

• Micro-Micron Filtration: Processed through automated particulate filtration production lines to bring instrument background counts near zero in sensitive channels.

• Safe and Anti-Microbial Growth Formulation: Utilizes modern preservatives to prevent algae, bacteria, and fungal deposit formation inside capillary tubing of the Excell 22 analyzer.

• Ready-to-Use Structure: Requires no shaking, mixing, or dilution, ensuring osmotic stability down to the last milliliter.

Technical Limitations, Maintenance Tips, and Operational Interactions

To prevent hematology chart fluctuations and protect the device flow cell, observing the following requirements is essential:

• Standard Storage Temperature Management: Store the sheath solution strictly between 2 and 30°C. Freezing breaks polymer bonds, generating micro-crystalline particles upon thawing that clog flow apertures.

• Preventing Environmental Dust Ingress: Avoid touching connectors or suction probes with bare hands or unsterile wipes during container changeovers; lint or dust ingress causes severe white blood cell scatterplot interference.

• Hermetic Inlet Connection: Ensure probe cap interfaces seal tightly on containers to prevent liquid evaporation and mineral salt concentration shifts.

Laboratory Staff FAQ

1. Why do bubbles or impurities in sheath solutions distort the WBC Differential scatterplot?
   Sheath fluid provides a clear pathway for cells passing through the laser beam. Air bubbles or suspended particles scatter laser light, causing optical sensors to misinterpret impurities as WBCs or pathological cells, completely distorting scatterplots.

2. Can deionized water or alternative sheath solutions be used for the Excell 22 machine?
   No; deionized water lacks the required refractive index and electrical conductivity, and extreme osmotic pressure differences immediately lyse blood cells. Non-standard solutions also cause severe hydraulic pump wear due to viscosity mismatches.

3. What is the role of antibacterial agents in Labnovation Sheath Fluid?
   Because sheath fluid continuously flows through capillary tubing, antibacterial compounds prevent biofilm formation inside flow cells and lines, avoiding hidden hydraulic blockages.
