Burrell 075-775-08-36 Wrist-Action Shaker

Overview

The Burrell 075-775-08-36 Wrist-Action Shaker is an electromechanically engineered laboratory shaker designed to replicate the gentle, elliptical motion of a human wrist—ideal for low-shear mixing of sensitive biological, clinical, and environmental samples. Unlike orbital or reciprocating shakers, this device employs a true wrist-action mechanism based on a cam-driven oscillating arm assembly, generating smooth, non-turbulent motion with minimal foaming or cell disruption. Its dual-platform architecture supports simultaneous independent operation of two sample zones—each configurable with interchangeable side-arm clamps or top-tier aluminum platforms—enabling flexible workflow integration in microbiology, immunoassay development, tissue dissociation, and reagent preparation. The unit operates within a precisely controlled ambient temperature range of 4–37 °C, making it suitable for cold-room applications as well as incubator-compatible environments.

Key Features

• True wrist-action motion: 385 cycles per minute at adjustable angles from 1° to 15°, enabling tunable shear stress—from mild suspension maintenance to vigorous homogenization.
• Dual-platform design: Two independently accessible oscillation zones accommodate varied vessel configurations—ideal for parallel processing of different sample types or volumes.
• Robust mechanical architecture: Precision-machined aluminum and stainless steel construction ensures long-term dimensional stability and resistance to corrosion from repeated solvent exposure.
• Integrated safety systems: Automatic thermal and current overload protection shuts down operation if motor stall or excessive load is detected—compliant with IEC 61000-6-2 electromagnetic immunity standards.
• Programmable timer: Digital control panel supports discrete timing intervals from 0 to 60 minutes or indefinite continuous operation, with audible end-of-cycle alert.
• CE-certified electrical system: Designed and tested to EN 61010-1:2019 safety requirements for laboratory equipment, including reinforced insulation and grounded chassis design.

Sample Compatibility & Compliance

The 075-775-08-36 accommodates a broad spectrum of laboratory vessels—including Erlenmeyer flasks (up to 500 mL), graduated cylinders, specimen containers, separatory funnels, and wide-mouth jars—via optional SUREGRIP® finger clamps, heavy-duty dual-bottle supports, and modular aluminum top platforms. All accessories are manufactured to ISO 9001-certified processes and meet USP material compatibility guidelines for non-pyrogenic, non-leaching contact surfaces. When used with validated accessories (e.g., silicone-coated clamps per USP ), the system supports GxP-aligned workflows requiring documented traceability and material certification. While not intrinsically rated for Class II biosafety cabinets, its compact footprint (43.2 × 38.9 cm base) and low acoustic emission (<55 dB(A)) permit safe integration into containment environments under engineering controls.

Software & Data Management

This analog-controlled shaker does not incorporate embedded microprocessor-based data logging or network connectivity. Operation is managed exclusively via front-panel mechanical timer and manual angle adjustment lever—ensuring operational simplicity, electromagnetic resilience in high-interference labs, and full compliance with legacy validation protocols where deterministic, non-software-dependent hardware is required. For regulated environments (e.g., FDA 21 CFR Part 11 or EU Annex 11), users may pair the unit with external calibrated timers and paper-based logbooks; IQ/OQ documentation templates are available from Burrell Scientific upon request. No firmware updates, cloud services, or proprietary drivers are involved—eliminating cybersecurity concerns and software obsolescence risks common in digitally intensive lab instruments.

Applications

• Microbial culture resuspension and aeration in clinical microbiology and antibiotic susceptibility testing (AST).
• Antibody-antigen binding kinetics studies requiring gentle agitation without denaturation.
• Cellular dissociation protocols for primary tissue digestion using collagenase or trypsin solutions.
• Environmental water sample homogenization prior to filtration or microbial enumeration (EPA Method 1603, ISO 9308-1).
• Pharmaceutical excipient blending and dissolution media conditioning under USP and guidance.
• Diagnostic reagent shelf-life verification through accelerated stability testing at defined oscillation parameters.

FAQ

What is the maximum flask size supported on each platform?
Each platform accommodates up to eight 250 mL Erlenmeyer flasks when using the optional top aluminum platform (P/N 075-765-31-00); with side-arm clamps, individual vessel capacity extends to 500 mL.
Can this shaker be operated inside a refrigerated chamber?
Yes—the unit is rated for continuous operation between 4 °C and 37 °C ambient temperatures, provided condensation is mitigated and airflow around ventilation grilles remains unobstructed.
Is the oscillation angle calibrated and traceable to NIST standards?
Angle adjustment is mechanically indexed via precision-machined detents; while not individually certified, the 0–15° range conforms to ASTM D2240-20 Annex A1 specifications for angular displacement repeatability in mechanical shakers.
Does the shaker include GLP-compliant audit trail functionality?
No—this is a Class I analog instrument without digital memory or electronic event logging; GLP compliance relies on external procedural controls and manual recordkeeping.
Are replacement parts and service manuals available internationally?
Yes—Burrell Scientific maintains global distribution channels for all OEM components, including side-arm shafts (P/N 075-778-02-00), SUREGRIP® clamps (P/N 075-777-00-00), and CE-marked power supplies—backed by a 2-year limited warranty.
