Bürkle Wide-Neck HDPE Reagent Bottles with Tamper-Evident Cap
Bürkle Wide-Neck HDPE Reagent Bottles are durable square laboratory and chemical containers designed for storing, packaging, sampling and transporting suitable powders, granules, pastes, reagents and other compatible materials.
Manufactured from high-density polyethylene (HDPE), these bottles combine a large neck opening with a stable square footprint, recessed labelling area and tamper-evident screw cap.
The wide opening makes filling, removing material and emptying easier than with a conventional narrow-neck reagent bottle, particularly when working with granular, powdered or pasty materials.
Cambridge offers the Bürkle 0342 series in capacities from 50 mL to 4,000 mL. Most sizes in the family carry a specific UN approval for solids; the 50 mL version does not have a UN authorization.

Important UN Approval Note
The Bürkle 0342 series is listed with UN approvals for solids on applicable sizes. The 50 mL bottle has no UN authorization.
A UN code shown for a bottle does not automatically mean the container is approved for transporting every chemical, liquid or dangerous good. Packaging selection must match the material, transport classification, closure, gross mass and applicable dangerous-goods requirements.
Which Bottle Size Should I Choose?
| Capacity | Typical Application |
| 50–100 mL | Small retained samples, powders, reagents and reference materials |
| 250–500 mL | Routine laboratory samples, granules, ingredients, pastes and chemical samples |
| 750–1,000 mL | Larger QA/QC samples, bulk powders, production samples and laboratory materials |
| 1,500–2,500 mL | Bulk samples, larger granules, powders and industrial or production materials |
| 4,000 mL | Large retained samples, bulk materials and higher-volume laboratory or industrial storage |
Why Use a Wide-Neck Reagent Bottle?
The wide opening is one of the most useful features of this bottle family. It makes the container easier to fill, empty and access when working with materials that are difficult to move through a small bottle neck.
Wide-neck bottles are especially useful for:
- Powders
- Granules
- Pastes
- Viscous materials
- Bulk ingredients
- Samples that need to be removed with a scoop or spatula
As capacity increases, the neck opening also becomes larger. The 1.5 L, 2.5 L and 4 L bottles use a GL 80 thread with a 69 mm internal neck diameter, making them particularly easy to access.
Tamper-Evident Screw Cap
Each Bürkle 0342 reagent bottle is supplied with a tamper-evident screw closure.
A tamper-evident closure provides visible evidence when the original closure has been opened, which can be useful for retained samples, production samples, raw materials and other applications where sample integrity and identification matter.
Tamper evidence should not be confused with a serialized security seal or formal chain-of-custody system. If your procedure requires individually numbered or traceable seals, additional sample-security controls may be required.
Stable Square HDPE Design
Unlike a conventional round laboratory bottle, the Bürkle wide-neck reagent bottle has an angular square cross-section.
The square profile provides a broad, stable base and can make more efficient use of shelf, cabinet and bench space.
It can also reduce the tendency of a bottle to roll if it is accidentally placed on its side.
Recessed Labelling Area
Each bottle includes a recessed area intended for labelling or marking.
This can help laboratories identify:
- Sample name
- Lot or batch number
- Collection date
- Contents
- Operator initials
- Storage information
Follow your facility's own labelling, WHMIS and sample-identification requirements when storing chemicals or regulated materials.
Why Choose HDPE?
High-density polyethylene (HDPE) is widely used for laboratory and industrial containers because it provides a useful combination of durability, low weight and chemical resistance for many applications.
Compared with LDPE, HDPE is generally more rigid and holds its shape more firmly, which suits the square reagent-bottle design.
Chemical Compatibility Matters
HDPE is resistant to many chemicals, but compatibility is not universal. Suitability depends on the exact chemical, concentration, temperature, exposure time and storage conditions. Check chemical compatibility before using the bottle with aggressive chemicals, solvents or hazardous substances.
Laboratory & Research Applications
Bürkle identifies laboratories, industrial operations and research facilities as typical environments for this reagent-bottle family.
Common applications may include:
- Reagent and chemical storage
- Sample collection
- Retained samples
- Powder and granule storage
- Research materials
- Raw-material samples
- Process samples
- QA/QC sampling
Industrial & Manufacturing QA/QC
The combination of a stable square bottle, wide access, tamper-evident closure and recessed labelling area makes the 0342 series particularly useful for industrial sample handling.
Quality departments can use appropriate sizes for incoming raw materials, retained samples, production samples, powders, granules and other materials where a secure and clearly labelled sample container is needed.
Food & Beverage Applications
Bürkle publishes food-contact compliance documentation covering the 0342 HDPE wide-neck reagent-bottle family.
Depending on your facility's procedures and the material being sampled, these bottles may be considered for suitable:
- Dry ingredients
- Powders
- Granulated ingredients
- Pastes
- Retained production samples
- Incoming raw-material samples
Confirm that the bottle, closure and sampling procedure meet your facility's food-contact, sanitation and quality requirements before use.
Thread & Neck Size Guide
The neck size increases substantially across the 0342 family:
- 50 mL: GL 28 thread, 21 mm internal neck diameter
- 100 mL: GL 32 thread, 24 mm internal neck diameter
- 250 mL: GL 45 thread, 35 mm internal neck diameter
- 500, 750 and 1,000 mL: GL 54 thread, 43 mm internal neck diameter
- 1,500, 2,500 and 4,000 mL: GL 80 thread, 69 mm internal neck diameter
If you intend to fill or remove material with a scoop, spatula or funnel, check the inside neck diameter rather than choosing by bottle capacity alone.
HDPE Reagent Bottle vs. LDPE Wide-Neck Bottle
Cambridge also offers a Bürkle Wide-Neck LDPE Bottle. The two bottle families solve somewhat different handling needs.
| Feature | 0342 HDPE Reagent Bottle | 0318 LDPE Wide-Neck Bottle |
| Material | Rigid HDPE | Flexible LDPE |
| Shape | Square / angular | Round |
| Closure | Tamper-evident screw cap | Screw cap |
| Labelling Area | Recessed labelling field | Standard bottle surface |
| UN Approval | Selected sizes approved for solids | Not the primary positioning of the 0318 family |
| Best Fit | Reagents, chemicals, retained samples, powders and industrial QA/QC | General laboratory samples where a flexible, squeezable bottle is useful |
Wide-Neck vs. Narrow-Neck Reagent Bottles
Wide- and narrow-neck reagent bottles serve different handling requirements.
Choose a wide-neck bottle when you need easier access for powders, granules, pastes, scoops or bulk filling.
A narrow-neck bottle may be preferable when more controlled pouring or dispensing of compatible liquids is more important than access to the interior.
