FAQ: Advanced Technical FAQ

1. What plastics are typically used for Plastic Laboratory Reagent Bottle Screw Cap Semi-Permeable Liquid Bottle Specifications Complete?

HDPE (High Density Polyethylene) for chemical resistance and low permeability; PP (Polypropylene) for general use and moderate autoclavability; PTFE (Polytetrafluoroethylene) for extreme chemical compatibility; FEP and PMP for specialty applications where transparency or high temperature is needed.

2. Which membrane options are available for the screw cap?

PES (Polyethersulfone) for high flow, PTFE for organic/volatile reagents, Polycarbonate for biological agents. These membranes balance semi-permeability (gas exchange) with barrier performance, as per ASTM F316.

3. How do these bottles withstand repeated sterilization?

Most Plastic Laboratory Reagent Bottle Screw Cap Semi-Permeable Liquid Bottle Specifications Complete products (HDPE/FEP/PMP variants) are autoclavable at 121-134℃, certified according to ISO 22975-1, withstanding >100 cycles without deformation or threading failure. Note: PP cap may have lower cycle tolerance due to material fatigue.

4. What is the impact of chemical compatibility on service life?

Service life exceeds 10 years under standard lab exposure, as measured by ISO/TR 10358 protocols. HDPE and PTFE show minimal permeability and no visible stress cracking after five years' exposure to ethanol, hydrochloric acid, and toluene.

5. Which standards are necessary for compliance in international laboratories?

Key standards: ISO 80369 (twist cap connection), FDA 21 CFR 177 (material safety for consumables), ASTM D4169 (storage safety), and where relevant, Good Manufacturing Practice (GMP) for pharmaceutical workflows.

6. How is leakage prevented with semi-permeable bottle technology?

Strict batch-by-batch QC, O-ring integrated cap/collar, and ultrasonic welded membranes assure gas transfer (where needed) but absolute liquid-tite integrity. All units pass 0.2atm (2m water) immersion tests per lot, exceeding industry average.

7. Can special neck finishes or safety features be implemented?

Absolutely—custom threads (DIN/GL-45, ISO 4796), integral pouring rings, tamper-proof seals, and color code banding are all available for traceability, automation compatibility, and regulatory compliance across diverse lab sectors.
