Product Description
Working with scarce or costly samples means preparing very small volumes without losing accuracy. These micro volumetric flasks hold just 1 mL or 2 mL to Class A standards, making it practical to prepare small standards and dilutions while conserving material. They fit well in microscale teaching and analytical workflows where sample volume is limited.
This listing is for catalog number 2306A-1: Volumetric Flask, Class A, Glass Stopper, 1 mL, Pack of 6. Each flask is machine-blown from borosilicate glass with a heavy-beaded neck tooled for a standard taper glass stopper that seals tightly. A hexagonal base helps keep these small flasks upright, and a large marking square leaves room for labels. Flasks are calibrated to contain at 20°C and are offered in 1 mL and 2 mL sizes. Add it to your LIGHT LABS order and keep your lab stocked.
Key Features
- Micro capacities – 1 mL and 2 mL sizes for small-volume preparations.
- Hexagonal base – Wider, stable footprint keeps small flasks from tipping.
- Glass stopper – Standard taper stopper forms a leak-tight seal.
- Class A accuracy – Made to ASTM E288 Class A and USP requirements.
- Borosilicate glass – Clear, chemically resistant and low expansion.
