For your chromatography setup, the 30x300mm PYREX column with a G3 frit is a standard laboratory glass piece used for separating and purifying complex mixtures.
Product Specifications
- Dimensions: This column typically has an inner diameter (ID) of 30mm and an effective length of 300mm.
- G3 Fritted Disc: A G3 porosity grade generally features a pore size range of 16 to 40 µm. This disc supports the stationary phase (like silica gel) while allowing the mobile phase to flow through smoothly.
- Material: Constructed from PYREX (borosilicate glass 3.3), known for high chemical durability and resistance to thermal shock.
- Stopcock: Most models include a PTFE (Teflon) stopcock for precise flow control without the need for vacuum grease.
- Filter Type: Integrated G3 sand core (sintered disc) that can filter out fine precipitates and supports packing media like silica gel.
- Flow Control: Typically equipped with a PTFE (Teflon) stopcock or a glass plug for precise flow adjustment.
- Top Fitting: Often includes a standard ground glass joint (e.g., 24/40 or 19/26) or is tooled for a rubber stopper fit.
