WIGGENS LC1024050 Volumetric Flask Shaker

Overview

The WIGGENS LC1024050 Volumetric Flask Shaker is an engineered orbital shaker designed exclusively for precise, reproducible mixing of solutions in standardized volumetric flasks—primarily 50 mL Class A or Class B borosilicate glass flasks. Unlike general-purpose platform shakers, this instrument integrates a rigid, custom-machined flask-holding tray with optimized eccentric drive geometry to ensure uniform angular displacement and consistent shear input across all 24 positions. Its operation relies on controlled orbital motion (typically 12–25 mm diameter) at variable speeds between 100 and 1500 rpm, enabling rapid dissolution, homogenization, and dilution preparation while minimizing bubble formation and splashing—critical for trace-level standard solution preparation in analytical chemistry, pharmaceutical QC, and environmental testing laboratories.

Key Features

• Dedicated 24-position tray engineered for secure retention of 50 mL volumetric flasks—prevents tipping, slippage, or neck deformation during high-speed agitation.
• Pulse-mode oscillation function allows programmable intermittent shaking cycles (e.g., 5 s on / 3 s off), enhancing solute dispersion in viscous or particulate-laden solutions without thermal buildup.
• Microprocessor-controlled timer with 1-second resolution and automatic shutdown after up to 60 minutes ensures protocol compliance and unattended operation.
• Brushless DC motor delivers stable speed control with ±2 rpm repeatability across the full 100–1500 rpm range, independent of load distribution or ambient temperature fluctuations.
• Compact footprint (463 × 304 mm) optimizes bench space in regulated lab environments where ISO/IEC 17025-compliant layout planning is required.
• Robust powder-coated steel housing and IP20-rated electronics provide long-term durability under routine decontamination protocols using 70% ethanol or diluted quaternary ammonium solutions.

Sample Compatibility & Compliance

The LC1024050 accommodates only standard-taper 50 mL volumetric flasks conforming to DIN EN ISO 1042 or ASTM E288 specifications. It is not compatible with conical flasks, centrifuge tubes, or non-standard neck geometries. The shaker meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. While not intrinsically safe, its design supports GLP- and GMP-aligned workflows when integrated into documented SOPs for reference standard preparation (e.g., USP , ISO/IEC 17025 Clause 7.2.2). Calibration verification can be performed using NIST-traceable tachometers; no factory calibration certificate is supplied, but users may establish internal performance qualification (PQ) protocols per ICH Q2(R2).

Software & Data Management

This is a stand-alone electromechanical instrument with no embedded software, network interface, or data logging capability. All operational parameters—including speed setpoint, timer duration, and pulse interval—are configured via front-panel membrane keys and displayed on a 3-digit LED screen. As such, it complies with FDA 21 CFR Part 11 requirements only in “non-electronic record” mode: settings are manually entered and visually verified prior to activation, with no audit trail generated. For labs requiring electronic records, integration with external LIMS or ELN systems must occur at the procedural level (e.g., operator logs speed/time in structured digital forms prior to run initiation).

Applications

• Preparation of certified reference material (CRM) dilutions for ICP-MS, AAS, and HPLC calibration curves.
• Homogenization of buffer stock solutions containing lyophilized enzymes or heat-sensitive proteins prior to aliquoting.
• Standardization of titrant solutions (e.g., EDTA, NaOH) per ISO 8655 and ASTM E200 guidelines.
• Mixing of spiked environmental water samples for recovery studies under EPA Method 500/600 series protocols.
• QC release testing of raw materials where volumetric accuracy directly impacts assay validity (e.g., pharmacopeial assays per USP ).

FAQ

Can the LC1024050 accommodate 100 mL or 250 mL volumetric flasks?
No. The LC1024050 is mechanically configured for 50 mL flasks only. WIGGENS offers separate models—LC1024100 (12-position, 100 mL) and LC1024250 (8-position, 250 mL)—with distinct tray geometries and center-of-mass compensation.
Is speed calibration traceable to national standards?
The unit does not include built-in calibration; however, speed accuracy can be verified externally using a handheld optical tachometer calibrated to NIST SRM 2034 or equivalent.
Does the shaker generate significant acoustic noise during operation?
At maximum speed (1500 rpm), sound pressure level is ≤58 dB(A) at 1 m distance—comparable to standard laboratory centrifuges and suitable for shared open-plan lab spaces.
What maintenance is required?
Annual inspection of drive belt tension and tray mounting screws is recommended. No lubrication of the motor or transmission is required due to brushless DC construction and sealed bearing design.
Can the pulse function be disabled?
Yes. Pulse mode is optional and defaults to continuous operation unless explicitly enabled via the front panel menu.
