Bürkle Narrow-Neck HDPE Reagent Bottles are durable laboratory and industrial bottles designed for the storage, packaging, sampling and transport of compatible liquids.
Manufactured from transparent high-density polyethylene (HDPE / PE-HD), the bottles allow the approximate liquid level and contents to remain visible while providing a lightweight, impact-resistant alternative to glass.
Each bottle is supplied with a blue polypropylene tamper-evident screw cap with a conical seal. The square bottle body improves shelf organization, while the recessed labelling area provides a protected location for sample, reagent or batch identification.
Available in 100 mL, 250 mL, 500 mL, 1000 mL and 2500 mL capacities, the Bürkle 0340 series is suited to laboratory, industrial QA/QC, food and beverage, environmental, research and production applications where secure liquid storage and controlled dispensing are required.

The narrow opening is designed to provide more controlled liquid dispensing than a wide-mouth bottle.
Bürkle specifically describes the narrow neck as helping to provide precise dispensing while reducing unwanted spilling.
The 100 mL, 250 mL, 500 mL and 1000 mL bottles have a 17 mm internal neck diameter. The larger 2500 mL version uses a 28 mm internal opening.
This makes the 0340 series particularly useful for liquids that are poured directly into smaller vessels, test containers, beakers or other laboratory equipment.
Each bottle includes a blue polypropylene screw cap with a conical seal and tamper-evident ring.
Bürkle specifies the cap system as providing leakproof storage when properly closed and used with a compatible liquid.
The tamper-evident ring provides visible evidence that the original closure has been opened.
The tamper-evident ring indicates that the original closure has been opened. It should not be treated as a serialized security seal or a complete chain-of-custody system where formal sample-security procedures are required.
The Bürkle reagent bottle has a square body rather than a conventional round bottle shape.
Flat sides allow bottles to sit closely together on laboratory shelves, in cabinets or in sample-storage areas.
This can make the 0340 series particularly practical when laboratories maintain several reagents, retained samples or reference materials in a limited storage area.
Bürkle incorporates a recessed labelling field into the bottle body.
This provides a defined location for identifying:
Laboratories should continue to follow their own WHMIS, sample-identification and quality-system labelling requirements.
Bürkle manufactures the 0340 reagent bottle from transparent HDPE.
This allows the contents and approximate liquid level to be visually inspected without removing the cap.
HDPE also provides a useful combination of low weight, toughness and resistance to many commonly handled laboratory and industrial materials.
HDPE and polypropylene are compatible with many laboratory chemicals, but compatibility is not universal. Confirm suitability for the exact chemical, concentration, temperature and expected contact time before storing or transporting a substance.
Bürkle identifies the 0340 series as a general-purpose liquid bottle for storage, packaging, sampling and transport.
Typical laboratory applications can include:
The secure closure, square shape and narrow neck also make these bottles useful in production and industrial quality-control environments.
Potential applications include:
Bürkle publishes food-contact documentation covering the 0340 narrow-neck reagent bottle family.
Suitable food and beverage applications may include:
Food-contact documentation does not replace a facility's own sanitation, allergen-control, chemical-compatibility or product-specific requirements.
HDPE bottles are commonly considered for suitable water, wastewater and environmental samples where the bottle material is compatible with the analytical method.
Potential applications include:
For regulated or trace-level environmental analysis, confirm that HDPE, the closure and any sample-preservation procedure are appropriate for the analytes being measured. Container requirements can vary by method.
| Feature | Narrow-Neck Bottle | Wide-Neck Bottle |
| Best For | Liquids | Liquids, powders, granules and viscous materials |
| Controlled Pouring | Better | Less controlled |
| Easy Filling | Best for liquids | Better for bulk material |
| Scoop / Spatula Access | Limited | Better |
| Internal Cleaning Access | More restricted | Easier |
Choose the narrow-neck reagent bottle when controlled liquid dispensing is the priority.
Choose a wide-neck bottle when easier filling, cleaning or access for powders, granules and viscous materials is more important.

The Bürkle 0340-series narrow-neck reagent bottles are made from HDPE / high-density polyethylene. They are not LDPE bottles.
Cambridge offers 100 mL, 250 mL, 500 mL, 1000 mL and 2500 mL capacities.
Bürkle specifies the PP tamper-evident screw cap with conical seal as providing leakproof storage when properly closed and used with compatible liquids.
Yes. The blue polypropylene screw cap includes a tamper-evident ring that provides visible evidence of first opening.
The 100 mL through 1000 mL bottles have a 17 mm internal neck diameter. The 2500 mL bottle has a 28 mm internal neck diameter.
The 100 mL, 250 mL, 500 mL and 1000 mL models use GL 32 threads. The 2500 mL model uses a larger GL 45 thread.
Narrow-neck bottles provide better control when dispensing or pouring liquids. They are particularly useful when transferring a liquid into smaller vessels where a wide-mouth opening could increase the chance of spilling.
Yes. Bürkle describes the bottles as transparent HDPE, allowing the approximate contents and fill level to be visually inspected.
Yes. Bürkle specifies a recessed labelling field on the square bottle body.
Bürkle markets the 0340 series for laboratory and industrial chemical applications. Chemical compatibility still depends on the exact substance, concentration, temperature and contact time and should be confirmed before use.
Bürkle publishes food-contact compliance documentation covering the 0340-series reagent bottles. Users should still confirm suitability for the specific food, ingredient, sanitation process and application.
They may be suitable for many environmental and water samples, but the analytical method should determine the required bottle material, preservative and closure.
Do not assume so. Bürkle does not list a UN dangerous-goods approval for the standard 0340 reagent bottle series. Dangerous goods require an appropriately approved means of containment for the specific material and transport requirements.
A reagent bottle is generally intended for storing or dispensing laboratory liquids, while sample bottles are selected around the requirements of the sample and analytical method. The Bürkle 0340 series can also be used for suitable sampling and sample transport applications.
