Product Description
Silica gel non-indicating coarse LR is a highly effective desiccant widely used in laboratories for moisture control. Unlike indicating silica gel, this variant remains colorless, making it ideal for applications where visual indicators are unnecessary. Its coarse granular form ensures optimal airflow and absorption efficiency, making it a staple in research labs, educational institutions, and industrial settings.
This laboratory-grade silica gel is chemically inert, non-toxic, and reusable after reactivation. It’s commonly used in desiccators, storage cabinets, and packaging to protect sensitive equipment and samples from humidity. Whether you’re a student setting up an experiment or a researcher preserving critical samples, this silica gel delivers reliable performance.
At eqipped, we ensure that every batch of silica gel meets stringent quality standards, so you can trust its consistency and effectiveness. Available in multiple pack sizes, it’s easy to find the right quantity for your needs.
Why This Silica Gel Stands Out
What makes this silica gel a top choice for labs? First, its coarse texture allows for better moisture absorption compared to finer grades. Second, the non-indicating property ensures no chemical interference in sensitive applications. Finally, its LR grade guarantees purity and reliability, which is crucial for accurate experimental results.
Many researchers and educators prefer this silica gel because it’s versatile. It works well in both small-scale experiments and large-scale storage solutions. Plus, its reusability makes it a cost-effective option for long-term use.
Common Applications in Labs
This silica gel is a go-to solution for various laboratory needs. Here are some of its key uses:
In desiccators, it maintains a dry environment for hygroscopic substances. For chromatography, it serves as a stationary phase in column separations. It’s also used in instrument storage to prevent corrosion and in sample preservation to avoid moisture-related degradation.
Students often use it in chemistry labs to keep reagents dry, while researchers rely on it for long-term storage of biological samples. Its non-reactive nature ensures it won’t alter the composition of stored materials, making it a safe choice for delicate work.
How to Use and Store Silica Gel
Using this silica gel is straightforward. Place the granules in a breathable container or desiccator, ensuring they’re not in direct contact with the items you’re protecting. For reactivation, heat the gel at 120°C for 2-3 hours to remove absorbed moisture, and it’s ready for reuse.
Storage is just as simple. Keep the silica gel in an airtight container when not in use to prevent premature saturation. Avoid exposure to liquids or high humidity, as this can reduce its effectiveness. With proper care, a single batch can last for multiple cycles.
Safety and Handling
While silica gel is non-toxic, it’s best to handle it with basic lab safety precautions. Wear gloves to avoid skin irritation, especially if handling large quantities. In case of accidental ingestion, seek medical advice, though it’s generally inert. Always store it away from food and beverages to prevent contamination.
For high-risk applications, ensure proper ventilation when reactivating the gel, as heating may release trapped moisture. eqipped recommends following standard lab protocols to maximize safety and efficiency.
FAQs
What is the difference between indicating and non-indicating silica gel?
Indicating silica gel changes color when saturated with moisture, while non-indicating remains colorless. Non-indicating is preferred when visual indicators aren’t needed or could interfere with experiments.
Can this silica gel be reused?
Yes, it can be reactivated by heating at 120°C for 2-3 hours to drive off absorbed moisture. This makes it a cost-effective solution for long-term lab use.
Is this silica gel safe for food storage?
No, this is laboratory-grade silica gel and is not intended for food applications. Use food-grade desiccants for edible items.
What pack sizes are available?
eqipped offers this silica gel in 500g, 1kg, and 5kg packs to suit different lab requirements.
How do I know when the silica gel is saturated?
Since it’s non-indicating, you’ll need to monitor its weight or reactivate it periodically based on usage. A noticeable decrease in drying efficiency is a sign of saturation.
