Laboratory & Scientific Supply Packaging

Tennessee Bottle manufactures clean, consistent PET cylinders and bottles designed for laboratory, scientific, and analytical applications. Using PET injection blow molding, we produce containers with tight dimensional control, smooth internal surfaces, and precise neck finishes that support leak-free sealing, accurate sampling, and dependable storage.

Laboratory packaging demands repeatability and cleanliness. From sample collection through analysis and storage, container performance plays a critical role in maintaining sample integrity. Tennessee Bottle supports short-run and mid-volume production for labs, testing services, and scientific suppliers that require consistent quality without excessive inventory commitments.

PET Bottles and Cylinders for Laboratory Use

Scientific and laboratory environments require packaging that minimizes variability and supports standardized workflows. PET, when properly specified, offers a strong balance of clarity, rigidity, and chemical resistance while maintaining the tight tolerances needed for reliable closure performance.

- Low particulate characteristics: Smooth interior and exterior surfaces help support clean handling and reduced contamination risk.
- Dimensional consistency: Repeatable bottle geometry supports automated handling, racking, and lab workflows.
- Precision neck finishes: Injection molded threads provide consistent sealing surfaces for dependable closure engagement.

- Clarity for inspection: Clear PET allows easy visual confirmation of fill level and sample condition.
- Cylindrical geometry: Well-suited for labeling, storage trays, and standardized lab equipment.

Dosing-Friendly Shapes and Closure Fit

Many aftermarket products are measured and poured in controlled amounts, making bottle handling and closure performance especially important. Dosing-friendly shapes help support stable grip and controlled pour, while consistent neck geometry supports compatibility with common caps, spouts, and dispensing closures.

Injection blow molding improves control over thread definition and neck concentricity, helping reduce variability that can contribute to sealing failures, torque inconsistency, or leakage during shipping.

All Quantities Accommodated

Our production model is optimized for short-run and mid-volume programs, making Tennessee Bottle a strong partner for new product launches, specialty treatments, private-label programs, and multi-SKU automotive lines. This approach supports brands that need flexibility for changing labels, seasonal demand, and frequent reorders without tying up inventory in oversized packaging runs.

Even at smaller volumes, we focus on repeatable bottle geometry and consistent neck finishes to support reliable closure fit, clean presentation, and dependable performance through distribution.

Common Laboratory and Scientific Applications

Our PET containers are used across a wide range of laboratory and scientific environments, including:

- Fluid sampling for testing and analysis
- Chemical and reagent storage (application-dependent)
- Oil, fuel, and industrial fluid testing
- Environmental sampling

Quality control and validation testing
Research and development laboratories
Diagnostic and analytical testing kits
Sample transport and short-term storage

TE Closure Compatibility and Sealing Performance

Many laboratory and scientific applications require evidence of sample integrity from collection through analysis. PET injection blow molded bottles with precise neck finishes support compatibility with tamper-evident (TE) closures, helping provide visual confirmation that samples have not been compromised.

Consistent thread geometry and neck concentricity also support reliable torque application, reducing the risk of leaks during transport, handling, and storage.

Designed for Sampling, Storage, and Transport

Laboratory containers often pass through multiple handling steps before testing. Injection blow molded PET bottles provide the rigidity and dimensional stability needed to maintain shape under stacking, vibration, and routine handling.

Clear, smooth wall surfaces also support labeling, barcoding, and sample identification, helping reduce errors and improve workflow efficiency in lab environments.

PET vs HDPE for Laboratory Containers

PET and HDPE are both used in laboratory packaging, but PET offers advantages where clarity, dimensional control, and sealing consistency are priorities. Injection molded neck finishes provide repeatable thread geometry that supports dependable closure performance and standardized lab processes.

HDPE may be selected for applications requiring broader chemical resistance or increased flexibility. Material selection should consider sample composition, storage duration, closure requirements, and handling conditions. Tennessee Bottle works with customers to evaluate these factors and select the appropriate packaging solution.
