Quark Glass QPE-3-5 250 mL Peptide Synthesis Vessel with 3-Way Stopcock. A specialized heavy-wall borosilicate glass reaction vessel engineered for solid-phase peptide synthesis (SPPS) and chemical reactions requiring controlled reagent addition and wash drainage. MPN / Catalog Model: QPE-3-5 Manufacturer & Line: Quark Glass / Peptide Synthesis Glassware Series Volumetric Capacity: 250 mL working volume Stopcock Assembly: Integrated 3-way PTFE stopcock design allowing seamless alternating between reaction agitation, vacuum filtration, and wash solvent drainage without opening the system Internal Fritted Disc: Includes a coarse or medium porosity glass fritted disc at the base to retain solid-phase resin beads while allowing rapid liquid displacement Material Construction: Premium, high-purity borosilicate glass providing excellent thermal shock resistance and chemical durability against harsh SPPS reagents (such as TFA, DMF, DCM, and piperidine) Primary Application: Solid-Phase Peptide Synthesis (SPPS), organic synthesis, solid-phase extraction, and custom chemical batch reactions
