LCS Laboratory Inc. is pleased to introduce a new line of Refractive Index Liquids (RIL) engineered specifically for Bulk Asbestos Analysis by Polarizing Light Microscopy (PLM). These liquids were developed to support analysts who rely on accurate dispersion staining behavior and stable refractive index values to confidently differentiate asbestos fibers in complex matrices.
Formulated for Regulatory Compliance and Analytical Reliability
Each formulation is produced in accordance with ISO/DIS 22262‑1, ensuring compatibility with the major North American asbestos test methods:
- NIOSH 9002
- OSHA ID191
- EPA 600/R‑93/116
By aligning our formulations with these standards, we help laboratories maintain method compliance while improving the consistency and repeatability of their PLM results.
Optimized Optical Properties for Dispersion Staining
Accurate asbestos identification depends on more than simply matching refractive index. Analysts require liquids with controlled viscosity, optical dispersion, and thermal stability to produce clean, interpretable dispersion colors under crossed polars.
Our RIL products are engineered to:
- Provide sharp, high‑contrast dispersion staining for chrysotile, amosite, crocidolite, and other regulated fibers
- Maintain stable refractive index values across normal laboratory temperature ranges
- Support smooth slide preparation without crystallization, streaking, or premature evaporation
- Deliver consistent optical behavior from batch to batch
These characteristics help reduce analytical uncertainty and support more confident fiber identification, even in challenging samples.
Manufactured in Canada for Quality and Supply Stability
All refractive index liquids are produced in our Canadian facility under controlled laboratory conditions. Local manufacturing allows us to maintain tight quality control, minimize supply chain delays, and offer a more cost‑effective alternative to imported products. Our RIL line is available exclusively through our online store, ensuring direct access for laboratories across Canada.
Available Refractive Index Values and Packaging Options
We currently offer four refractive index values commonly used in asbestos PLM:
To accommodate different laboratory workflows, we provide three packaging sizes:
- 15 mL bottles — suitable for research, training, and low‑volume use
- 30 mL bottles – the most popular size for commercial labs. Enough for analysis of about 500 samples
- 100 mL bottles — ideal for large volume commercial asbestos analysis
High‑Quality Liquids at a Lower Cost
Because our products are manufactured domestically, we are able to offer pricing that is 20%–40% lower than comparable imported refractive index liquids. This allows Canadian laboratories to maintain high analytical standards while reducing consumable costs.
Enhance the Accuracy of Your PLM Asbestos Analysis
Our refractive index liquids were developed with one goal in mind: to support professional analysts with reliable, method‑compliant optical performance. If your laboratory performs asbestos identification by PLM, these liquids provide a stable, cost‑effective solution tailored to your needs. You can explore the full product line and order directly through our web store.
