Bürkle Brown LDPE Wide-Neck Bottles are light-protective laboratory and industrial bottles designed for the storage, transport and handling of compatible liquids, powders, granules and pastes.
Manufactured from brown low-density polyethylene (LDPE), the bottles help reduce exposure of light-sensitive contents to UV light. This makes them useful for products such as flavours, essential oils, chemical solutions, food additives and other photosensitive materials.
The wide neck makes filling, emptying and cleaning easier than with a narrow-neck bottle, while the supplied liquid-tight screw cap helps provide secure storage and transport.
Cambridge offers the Bürkle 0320 series in 250 mL, 500 mL and 1000 mL capacities for food and beverage, laboratory, pharmaceutical, chemical, cosmetics and industrial QA/QC applications.
| Bürkle Part # | Capacity | Height with Cap | Container Ø | Thread | Inside Neck Ø |
| 0320-0250 | 250 mL | 127 mm | 64 mm | GL 40 | 31 mm |
| 0320-0500 | 500 mL | 158 mm | 77 mm | GL 50 | 39 mm |
| 0320-1000 | 1000 mL / 1 L | 207 mm | 95 mm | GL 65 | 50 mm |
The brown colour of the Bürkle 0320 bottle is designed to absorb UV light and help protect light-sensitive contents.
This can be important for materials that may degrade, discolour or lose flavour, aroma or performance when exposed to light.
Examples can include:
Bürkle identifies the brown bottle as light-protective and states that the brown colouring absorbs UV light. If your material has a validated light-protection requirement, confirm that the bottle provides the protection required by your formulation, method or storage specification.
The wide opening makes these bottles easier to fill and empty than narrow-neck containers.
This is particularly useful with:
The larger opening also makes it easier to access the inside of the bottle during cleaning and reuse.
Bürkle uses a smooth, round, undercut-free bottle design to simplify handling and cleaning.
Bürkle specifies the 0320 series with a liquid-tight screw cap.
The closure is intended to provide protected storage and secure transport of compatible materials when properly closed.
Do not assume that a liquid-tight laboratory bottle is automatically suitable for transporting regulated dangerous goods. Dangerous-goods packaging requirements depend on the substance, classification, packing group, mode of transport and applicable regulations.
The Bürkle 0320 bottle is manufactured from low-density polyethylene, or LDPE.
LDPE is more flexible than many rigid laboratory plastics, making the bottle comfortable to handle and easier to squeeze than comparable HDPE or polypropylene containers.
Its combination of flexibility, impact resistance and wide-neck access makes the bottle useful for both laboratory and production environments.
Bürkle publishes food-contact documentation covering the brown LDPE 0320 bottle series.
Potential food and beverage applications include:
Bürkle's food-contact declaration states that the applicable LDPE products may be used for long-term food storage at room temperature or below, and under specified short-term heating conditions.
Food-contact documentation does not replace application-specific review. Confirm compatibility with the actual food, ingredient, temperature, storage duration and sanitation procedure before use.
Brown LDPE wide-neck bottles are useful when laboratory materials require both easy access and some protection from light.
Potential applications include:
Bürkle identifies pharmaceutical and cosmetics industries among the typical applications for the 0320 bottle family.
The brown LDPE bottle can be useful for compatible light-sensitive:
Regulated facilities should verify that the bottle, closure, cleaning procedure and documentation meet their own quality-system requirements.
The wide-neck format is also useful for industrial samples and compatible chemical materials that are difficult to handle through a narrow opening.
Potential applications include:
LDPE is compatible with many materials, but it is not universally resistant to every chemical. Confirm compatibility with the exact chemical, concentration, temperature and expected contact time before use.

They are manufactured from brown low-density polyethylene, also identified as LDPE or PE-LD.
Bürkle uses brown colouring to absorb UV light and help protect light-sensitive contents from exposure.
Bürkle officially describes the bottles as brown LDPE. They serve a similar light-protection purpose to products commonly searched for as amber laboratory bottles, but the manufacturer's specified colour is brown.
Cambridge offers 250 mL, 500 mL and 1000 mL capacities.
Bürkle specifies the screw-cap bottle as liquid-tight when properly closed and used with a compatible material.
Bürkle identifies the bottles for compatible liquids, pastes, powders and granulates. Exact suitability depends on the material being stored.
A wide neck makes filling, removing contents and cleaning easier, particularly for viscous liquids, pastes, powders and granules.
Bürkle publishes food-contact documentation covering the 0320 brown LDPE bottle series. Users should still verify suitability for the specific food, ingredient, temperature and storage conditions.
They may be suitable for many compatible chemicals, but LDPE resistance depends on the chemical, concentration, temperature and exposure time. Check compatibility before use.
The standard Bürkle 0320 brown LDPE bottles should not be assumed to be sterile unless sterility is specifically stated on the product configuration or documentation.
Do not assume so. Liquid-tight construction does not by itself mean that the bottle is UN approved or suitable for regulated dangerous-goods transport.
The 250 mL bottle uses GL 40, the 500 mL bottle uses GL 50 and the 1000 mL bottle uses GL 65.
Cambridge Environmental Products supplies Bürkle brown LDPE wide-neck bottles in Canada in 250 mL, 500 mL and 1000 mL sizes for laboratory, food and beverage, pharmaceutical, chemical, cosmetics and industrial applications.
Cambridge Environmental Products supplies Bürkle bottles, containers, samplers and laboratory handling products across Canada.
If you are unsure whether brown LDPE is appropriate for your application, send us the material being stored, required capacity, storage temperature, expected storage time and whether light protection or food-contact documentation is required.
The correct bottle depends on the material being stored, required light protection, neck opening, chemical compatibility and storage conditions.
Cambridge can help compare brown LDPE, clear LDPE, polypropylene, HDPE and glass bottle options for your application.
