Key Features

Single-Arm Box Corer

Utilizes an innovative single-arm mechanism for efficient and convenient operation. Its large 0.25 m² sampling box makes it the ideal choice for obtaining large-volume, minimally disturbed samples.

Standard Box Corer

As a widely adopted workhorse, this model is robust, simple to operate, and offers a high success rate. It reliably retrieves surface sediments while providing high-quality overlying water samples, making it suitable for various routine geological, chemical, and biological investigations.

Stabilized Frame-Type Box Corer

By incorporating a stabilizing external frame, this design significantly increases the equipment’s landing area and stability. It fundamentally solves the inherent challenge of corer overturning on soft substrates, enabling precise in-situ sediment collection.

Flow-Guide Box Corer

Building upon the frame-type design, this model integrates a flow-guide device. By increasing effective weight and optimizing the penetration process, it achieves a substantially greater penetration depth in compact sediments while maintaining excellent stability, representing a dual breakthrough in both stability and sampling depth.

Applications

Environmental Baseline & Impact Surveys

Benthic Habitat Studies

Geotechnical & Sedimentological Investigations

Deep-Water Sampling Operations

 Product Overview & Key Features:

Frankstar Technology’s Box Corer is a precision marine geological sampling device designed to collect large-volume, undisturbed soft sediment block samples along with overlying seabed water. Engineered to minimize bow-wave effects and sample distortion, it provides pristine environmental and geotechnical sediment samples for scientific and industrial offshore surveys.

Key Specifications & Capabilities:

Minimal Sample Disturbance: Flow-guided design and automatic top/bottom sealing mechanisms prevent sediment washout and preserve original seabed stratification.

Heavy-Duty Construction: High-grade stainless steel sampling box with corrosion-resistant frame ensures durability in harsh deep-sea conditions.

Versatile Configurations: Available in multiple models (including single-arm and stabilized frame options) with customizable sample box sizes (e.g., 0.05 m², 0.1 m², 0.25 m²) and variable penetrative weights.

Applications: Widely used in marine benthic biological research, ocean geochemical surveys, offshore wind farm site analysis, and environmental monitoring.
