1、 Working principle: Collaborative effect of mechanical flipping and intelligent control
Fully automatic flip oscillatorBy combining mechanical devices with intelligent control systems, the periodic flipping motion of sample containers can be achieved, and its core principle can be divided into the following three parts:
drive system
Motor and transmission mechanism: DC or AC motors are used to convert rotational motion into reciprocating oscillation of oscillator arms through transmission mechanisms such as gears, belts, or cams.
Flip motion: The oscillator arm is connected to a fixture or tray to fix the sample container (such as a test tube, flask, 2L glass bottle, etc.), and under the action of the transmission mechanism, it can be flipped back and forth 180 degrees, or rotated forward for 2 minutes and stopped for 5 seconds, and rotated backward for 2 minutes and stopped for 5 seconds in an intermittent mode.
control system
Microcomputer control: supports 0-45 revolutions per minute digital speed regulation, 0-99 hours and 59 minutes timing function, and some models are equipped with a constant temperature module (temperature adjustable).
Parameter preset: Users can set parameters such as speed, time, and flipping direction (alternating forward and reverse or unidirectional) through the LCD panel, and the device automatically executes and records operating data.
safety protection
Fully enclosed structure: The protective cover adopts a movable sliding door design, which facilitates the loading and unloading of samples while preventing liquid splashing.
Multiple protections: flip power-off device, leakage protection, overload protection ensure safe operation and prevent equipment damage or personal injury.
2、 Core use: A standardized tool for multi-disciplinary experimentation and production
Fully automatic flip oscillatorBy simulating the natural flipping process, liquid mixing, reaction promotion, or sample pretreatment can be achieved, which is widely used in the following fields:
Environmental monitoring: Identification of leaching toxicity of solid waste
Standard basis: Complies with China's "Toxicity Methods for Solid Waste Leaching - Sulfuric Acid and Nitric Acid Method" (HJ/T299-2007), "Toxicity Methods for Solid Waste Leaching - Acetic Acid Buffer Solution Method" (HJ/T300-2007), and US EPA Method 1311.
Experimental process: Solid waste and leaching solution (such as sulfuric acid/nitric acid solution, acetic acid buffer solution) are placed in a container in proportion. The natural leaching process is simulated by flipping and oscillating, and the concentration of harmful substances (such as heavy metals and volatile organic compounds) in the leaching solution is detected to determine the toxicity level of the waste.
Advantages: Fully enclosed structure avoids cross contamination, constant temperature module ensures stable reaction conditions, and strong data traceability.
Biochemical Research: Cell Culture and Enzyme Reaction Optimization
Cell culture: By gently flipping, gas exchange is promoted to prevent cells from depositing at the bottom of the container and improve culture uniformity.
Enzyme reaction: accelerates the mixing of reactants, shortens reaction time, and is suitable for enzyme activity determination, substrate conversion rate research, and other scenarios.
Pharmaceutical industry: Uniform mixing of drug ingredients
Formulation development: During the process of drug dissolution and suspension preparation, the components are evenly distributed through flipping oscillation to avoid differences in efficacy caused by excessive local concentration.
Quality control: Simulate the mixing process in actual production, verify drug stability, and provide data support for large-scale production.
Food Industry: Additive Mixing and Safety Testing
Ingredient mixing: In the research and development stage of food additives such as preservatives and pigments, the mixing effect of different formulas is tested by flipping and shaking to optimize product taste and stability.
Pollutant detection: Pre treat and mix food samples, extract target analytes (such as pesticide residues and heavy metals), and perform quantitative analysis using chromatography or mass spectrometry instruments.
Agricultural field: pesticide residue detection
Sample pretreatment: Mix agricultural products (such as vegetables and fruits) with extraction solution, disrupt cell structure through flipping oscillation, release residual pesticides, and facilitate subsequent purification and detection.
Method validation: Compare the effects of different flipping conditions (such as rotation speed and time) on pesticide extraction efficiency, and establish a standardized detection process.
Educational Research: Teaching Experiments and Scientific Exploration
Experimental teaching: Provide students with controllable experimental conditions, demonstrate basic chemical/biological processes such as mixing and reaction, and cultivate experimental operation skills.
Research exploration: Support cutting-edge research such as new material synthesis and bioreactor optimization, and explore optimal process conditions through parameter adjustment.
