Reagent Bottle Glass Material Chemical Compatibility

Borosilicate glass reagent bottle fits most aqueous solution, salt solution and common organic solvent. But glass material cannot be used for hydrofluoric acid and strong‑concentration alkaline sample with long‑term contact. Under long‑time strong alkali soaking condition, glass inner surface will be corroded and release silicon impurity into stored sample. Wholesale buyers need to sort out sample chemical property list, avoid putting incompatible chemical liquid inside glass reagent bottle.

Pfa Bottle Anti‑Corrosion Performance For Special Corrosive Sample

Pfa bottle owns excellent comprehensive chemical inertness. It adapts to strong acid, strong alkali and special fluorine‑containing reagent which ordinary glass cannot bear. Pfa material also keeps good performance under moderate high‑temperature storage condition. But pfa bottle has higher procurement cost compared with glass reagent bottle. Buyers should allocate container type rationally according to sample risk grade, using pfa bottle only for special corrosive sample scenarios.

Reagent Bottle Sealing Structure And Volatilization Prevention Capacity

Screw‑thread mouth reagent bottle quality largely depends on thread matching and inner gasket material. Poor‑fit screw mouth brings solvent volatilization risk. Gasket material must resist erosion from stored chemical liquid. Ordinary rubber gasket will swell and degrade when contacting organic solvent. For volatile reagent sample, buyers should verify sealing performance through long‑time inversion placement test of filled sample bottle.

Light Shielding Requirement For Light‑Sensitive Chemical Sample Storage

Some chemical samples degrade quickly under illumination. For such substance, amber brown light‑shield reagent bottle becomes necessary selection. Transparent clear bottle cannot block ultraviolet ray and visible light. Wholesale buyers should distinguish transparent reagent bottle and amber light‑shield reagent bottle clearly in ordering document. Do not adopt transparent bottle to store photosensitive sample to prevent sample composition deterioration.

Dimension And Mouth Caliber Matching Of Sample Storage Bottle

Different sample‑processing workflow puts forward different requirement for bottle mouth caliber. Wide‑mouth reagent bottle suits solid powder sample filling and taking out. Narrow‑mouth version fits liquid reagent storage. Large‑volume sample needs big‑capacity bottle, while trace sample preservation selects small‑volume specification. When placing bulk order, buyers should classify sample form including solid powder, common liquid and trace‑amount liquid, and select corresponding bottle caliber and volume parameter.
