Ground glass distillation joints

Form matching glass contact joints, grind seats and verify retained atmospheric vapor/liquid connections; discovery hypothesis only.

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

Form matching glass contact joints, grind seats and verify retained atmospheric vapor/liquid connections
Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.

What remains unresolved

Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
Pressure range, leakage, thermal expansion, joint lubrication and chemical compatibility unknown. Lubricant-free trial only; if grease/sealant is required, that additional chemical bootstrap cannot be omitted.
