A comprehensive bottle range for liquid filling, sample collection and storage.
Transparent models are made from polypropylene (PP) with PP closures and are autoclavable at 121 °C; natural/amber/black models use high-density polyethylene (HDPE) bottles with PP closures and are intended for gamma or e-beam sterilization.
The wide-mouth geometry speeds up filling and cleaning, while the thickened, linerless inner-ring PP cap delivers reliable leak-tight performance.
Key Features
Leak-tight, linerless inner-ring PP cap — no liner shedding, easy to torque, excellent seal integrity.
Wide-mouth opening for fast liquid filling/dispensing and easy cleaning.
Sterilization matrix: Transparent PP bottle + PP cap — steam autoclave at 121 °C and gamma/e-beam; HDPE bottle + PP cap — gamma/e-beam only (HDPE is not recommended for autoclaving).
Light-protection options: amber/black bottles help minimize light transmission for photosensitive liquids.
Durable materials: PP offers heat resistance; HDPE provides impact resistance and moisture barrier for transport.
Food-contact ready: resins commonly used for food-contact applications; documentation can be supplied on request.
Which management systems do you certify to and why does it matter?
We are certified to ISO 9001 (quality) and ISO 22000 (food safety), supporting robust process control, risk management and traceability for food-contact supply.
What are typical applications?
Liquid filling, storage and transport (water samples, buffers, reagents, oils; verify compatibility); choose amber/black for light-sensitive contents; HDPE is suitable for low-temperature handling and field sampling.
Do you offer free samples and how is freight handled?
Free samples are available; freight is negotiable based on destination, service level and weight/volume.
Do you supply UN-approved configurations and what tests are involved?
Yes—UN-approved options are available. Typical tests include drop, stacking, hydrostatic/pressure, leakproofness and vibration, with proper marking/closure instructions per regulations.
Are bottles supplied sterile?
Non-sterile by default; choose irradiated supply or sterilize on your side (typical steam conditions: 121 °C, ≥15 psi, ≥30 min).
What are the practical temperature and chemical limits?
HDPE offers very good resistance to many acids/bases/alcohols; PP provides higher heat tolerance for workflows involving autoclaving. Always verify with your media.
Are amber/black versions suitable for light-sensitive contents?
Yes—amber/black bottles reduce UV transmission; many products state compliance with USP light-transmission criteria for light-resistant containers.
How reliable is the leak-tightness with a linerless closure?
The linerless inner-ring PP closure is a widely used lab design; major brands claim leak-proof performance when properly closed and validated (e.g., inversion tests).
Do you offer sterile supply?
Standard supply is non-sterile. We offer paid gamma/e-beam sterilization.
Can transparent PP be autoclaved? What about HDPE?
Transparent PP is autoclavable at 121 °C; HDPE is not recommended for steam autoclaving—use gamma/e-beam instead.
What are the materials and are they food-contact compliant?
PP bottle + PP cap (transparent) or HDPE bottle + PP cap (natural/amber/black). Both PP and HDPE are commonly used for food contact; US 21 CFR 177.1520 documentation can be supplied on request.
