Handling, Storage & Safety Guide
Everything you need to safely receive, store, handle and dispose of laboratory chemicals — storage classes explained, hazard symbols decoded, and shelf-life guidance.
Chemical Storage Classes
Every product supplied by Kiran Light Group carries a storage class on its label and Certificate of Analysis. The class tells you how each chemical must be segregated and stored to remain stable and safe. Always store incompatible classes apart and follow the Safety Data Sheet (SDS) for each product.
Solvents & Organics
- Store in a ventilated flammables cabinet, away from ignition sources
- Keep at recommended temperature (often cool, dry conditions)
- Bond and ground containers when dispensing bulk volumes
- Keep away from oxidisers and strong acids
- Examples: ethanol, acetone, toluene, diethyl ether
Acids, Bases & Salts
- Store in corrosion-resistant, ventilated cabinets
- Segregate acids from bases and from flammables
- Use secondary containment (trays) for liquids
- Keep high-purity salts dry and tightly sealed
- Examples: hydrochloric acid, sodium hydroxide, buffers
Biochemicals & Stains
- Store refrigerated (2–8 °C) or frozen per the label
- Protect light-sensitive dyes & stains from direct light
- Avoid repeated freeze–thaw cycles; aliquot where possible
- Keep desiccated if hygroscopic
- Examples: enzymes, biological stains, reagent kits
Reading the Label & Certificate of Analysis
Every pack ships with a label and a Certificate of Analysis (CoA). Here's what each field means and why it matters:
| Field | What to Look For | Why It Matters |
|---|---|---|
| CAS Number | Unique identifier for the substance (e.g., 64-17-5 for ethanol) | Exact identity |
| Purity / Assay | Grade such as ≥99% (HPLC), AR/GR, or LR as stated on the CoA | Fit for method |
| Batch / Lot No. | Traceable to the matching Certificate of Analysis | Traceability |
| Pack Size | Net quantity — e.g., 25 g, 100 g, 500 g, 100 mL, 1 kg | Right quantity |
| Hazard Pictograms | GHS symbols with H- and P-statements; refer to the SDS | Safe handling |
| Storage & Shelf Life | Storage condition and best-before / re-test date | Stability |
Storage Conditions at a Glance
| Product Type | Recommended Storage | Key Precaution |
|---|---|---|
| Organic Solvents | Cool, ventilated flammables cabinet | Away from ignition |
| Acids & Bases | Corrosion-resistant cabinet, segregated | Never store together |
| High-Purity Salts & Inorganics | Dry, tightly sealed, room temperature | Keep desiccated |
| Biological Stains & Dyes | Cool, dark; some refrigerated | Protect from light |
| Biochemicals & Enzymes | Refrigerated 2–8 °C or frozen per label | Avoid freeze–thaw |
Bulk & Standing Supply — What to Know
Running a routine assay or production process? Kiran Light Group offers standing supply of chemicals and reagents on flexible schedules, with reserved stock and volume pricing.
| Plan | Cadence | Includes |
|---|---|---|
| Weekly Supply | Every 1–6 days | Selected pack sizes + Certificate of Analysis per batch |
| Monthly Supply | Every 7–27 days | Pack sizes + CoA + reserved stock |
| Quarterly Supply | Every 28+ days | Pack sizes + CoA + reserved stock + priority dispatch |
Standing Supply Tips
- An advance may be required when the standing order is set up
- Schedules and quantities can be adjusted before each dispatch
- Every dispatch ships with a batch-matched Certificate of Analysis
- Contact us for volume pricing and reserved stock on bulk orders
Quick Safety & Handling Tips
- Always read the Safety Data Sheet (SDS) before opening a new chemical
- Wear appropriate PPE — lab coat, safety goggles and gloves suited to the substance
- Handle volatile, toxic or odorous chemicals inside a fume hood
- Segregate incompatible classes (acids/bases, oxidisers/flammables) in storage
- Label every decanted container and never return unused material to the stock bottle
- Check the shelf-life / re-test date and dispose of expired stock per local regulations
- Keep the batch-matched Certificate of Analysis for your records and QC
