Bürkle Sealable Wide-Neck Bottles are durable HDPE sample containers designed for secure storage, shipment and handling of liquids, powders, granules, pastes and retained samples.
The key feature is the integrated sealing eyelet system. Both the screw cap and bottle incorporate sealing points that can be secured with an appropriate tamper-evident seal, helping users determine whether the bottle has been opened after sealing.
Manufactured from high-density polyethylene (HDPE / PE-HD), the bottles are supplied with a lined screw cap and are specified by Bürkle as liquid-tight. The wide neck makes filling, emptying and cleaning easier, particularly with viscous materials, powders and granules.
Cambridge offers the Bürkle 0322 series in 250 mL, 500 mL, 1000 mL and 2000 mL capacities for laboratory, industrial QA/QC, food and beverage, pharmaceutical, chemical and sample-retention applications.
Standard laboratory bottles can securely contain a sample, but they do not necessarily provide evidence that the container has remained unopened.
Bürkle addresses this by incorporating sealing eyelets into both the screw cap and bottle body.
Once an appropriate seal is installed through the eyelets, opening the bottle requires disturbing or removing that seal. This makes the bottle particularly useful when sample integrity and visible evidence of opening are important.
Typical applications include:
The bottle itself incorporates sealing eyelets but does not provide tamper evidence until an appropriate seal is installed. Use a suitable numbered tamper-evident seal when sample opening history or identification needs to be controlled.
Bürkle's SampleSafe seals are designed specifically for retained samples and containers with sealing eyelets.
Each red polypropylene seal has an individual 9-digit serial number for unique identification. Bürkle uses a one-way tightening mechanism and stainless spring-steel insert so attempts to open or manipulate the seal leave visible traces.
SampleSafe seals are supplied in packs of 100 under Bürkle part number 5399-2902.
Pairing a numbered seal with the sample ID recorded in your QA/QC documentation can provide a much stronger sample-control process than an unsealed bottle alone.
A numbered security seal can support sample identification and provide visible evidence of opening. Formal chain-of-custody requirements may also require documentation of possession, transfer, dates, signatures and other information according to the applicable procedure.

The large opening makes the 0322 series particularly useful for materials that are difficult to transfer through a conventional narrow-neck sample bottle.
Examples include:
The wide neck also makes it easier to remove material using an appropriate spatula or sampling tool and simplifies internal cleaning when the bottle is reused.
Bürkle manufactures the bottles from high-density polyethylene (HDPE) and supplies them with a lined screw cap.
The manufacturer specifies the system as liquid-tight, making it suitable for protected storage and transport of compatible liquids when properly closed.
HDPE is suitable for many chemicals but is not universally compatible with every substance. Confirm compatibility with the exact chemical, concentration, temperature and expected contact time before use.
The sealable design makes this bottle particularly useful for retained samples and reference samples.
A production facility can collect a representative portion of a raw material, intermediate or finished product, seal the bottle, record the security-seal number and store the sample for later review.
Potential applications include:
Bürkle identifies the food and beverage industry among the intended applications for the 0322 series and publishes food-contact documentation for the bottle family.
Potential applications include:
Food-contact documentation should still be reviewed against the specific food, storage duration, temperature and sanitation procedure used by the facility.
Sealable HDPE bottles can also be useful in environmental and wastewater programs where a sample needs to remain identifiable and protected during transport or storage.
Potential applications include:
Environmental sample containers must be selected according to the analytical method. Confirm that HDPE, the cap liner, required preservative and bottle preparation are appropriate for the analytes being tested.
Bürkle also identifies pharmaceutical applications for sealed sample storage and transport.
The bottle may be useful for compatible:
Regulated facilities should verify that the container and sealing process meet their own approved sampling, storage and documentation procedures.
Bürkle positions the 0322 series for secure storage and transport of compatible chemicals and industrial samples.
The wide mouth is particularly useful where conventional reagent bottles are difficult to fill with:
Bürkle describes the bottles as suitable for secure storage or transport of samples, chemicals and hazardous materials where the HDPE bottle and closure are compatible with the contents.
The manufacturer's description of hazardous-material applications does not by itself establish UN dangerous-goods approval. Transport of regulated dangerous goods in Canada requires an appropriate means of containment for the specific substance, classification, packing group, quantity and mode of transport.

The Bürkle 0322 bottle includes sealing eyelets on both the screw cap and bottle. An appropriate security seal can be passed through these eyelets to provide visible evidence if the container is opened.
A security seal should not be assumed to be included with the bottle unless specifically stated. Bürkle offers SampleSafe sequentially numbered seals separately for this purpose.
SampleSafe is a red polypropylene tamper-evident seal with an individual 9-digit serial number. Bürkle part number 5399-2902 is supplied in packs of 100.
It is better described as sealable and tamper evident when used with an appropriate security seal. No sample container should be described as completely tamper proof.
Yes. Bürkle specifies the HDPE bottle with lined screw cap as liquid tight when properly closed and used with compatible contents.
Bürkle identifies liquids, powders, granules and pastes as suitable material types, subject to chemical and application compatibility.
The wide opening makes filling, removing samples and cleaning easier, particularly for powders, granules, pastes and viscous materials.
Yes. The sealable design is particularly useful for retained and reference samples where visible evidence of opening and unique seal identification can support the facility's sample-control procedure.
The bottle and numbered seals can support tamper evidence and sample identification, but formal chain-of-custody procedures may require additional documentation and handling controls.
Bürkle publishes food-contact documentation for the 0322 family and identifies food and beverage applications. Users should still confirm suitability for the specific product and storage conditions.
Yes, for compatible chemicals. Always verify HDPE and closure compatibility with the exact chemical, concentration, temperature and contact time.
Do not assume so. Bürkle's sealable 0322 bottle should not be treated as UN dangerous-goods packaging unless the specific configuration carries the required approval for the intended shipment.
Cambridge offers 250 mL, 500 mL, 1000 mL and 2000 mL sizes.
