Headspace vials are common consumables used in gas phase experiments, especially in gas chromatography (GC) analyses. These vials are typically used to prepare headspace samples containing the sample, dilution solvent, matrix modifier, and headspace. In simple terms, laboratory bottles used for headspace analysis are referred to as headspace vials. These...

Thin-Layer Chromatography (TLC) is a highly useful technique for monitoring reactions and selecting suitable solvents in column chromatography. Common stationary phases for TLC include alumina or silica gel, while the mobile phase is a polar solvent. The procedure involves spotting the reaction mixture on a thin plate and utilizing capillary...

Microliter centrifuge tubes, also known as EP tubes, are small centrifuge tubes designed for use with microcentrifuges, enabling the separation and centrifugation of small-volume reagents. The tube has a round mouth at the top and a conical shape at the bottom. The round mouth enhances mechanical strength, while the conical...
