The separatory funnel oscillator is also widely used in food safety testing, such as the determination of residual pesticide residues in rice, analysis methods for edible hydrogenated oil, and hygiene standards for artificial butter

Experiments on the determination of benzoic acid in fruits and vegetables

1Vertical multipurpose oscillator for separating funnelAnalysis methods for hygiene standards of edible hydrogenated oil and margarine;

The analysis method for hygiene standards of edible hydrogenated oil and margarine has been specified. In the experimental steps for testing the nickel and copper content in margarine, 30mL of 0.5mol/L hydrochloric acid was added to the margarine sample,

After heating in a boiling water bath, extract three times using a separatory funnel. If the required time for one oscillation is 3 minutes and the time for three oscillations is 9 minutes, and 10 samples are taken in a day, three samples are measured in parallel, for a total of 30 samples,

In this way, the daily time spent on extraction oscillation is 270 minutes. If this experimental process is usedVertical multipurpose oscillator for separating funnelInstead of manual oscillation, extraction of 10 samples can be completed at once,

It only takes three times to complete and has a timed function. As long as the staff sets it up, they can go on to do other experiments. This way, the staff can save a lot of valuable time throughout the day,

more importantlyVertical multipurpose oscillator for separating funnelThe extraction effect is better than manual operation, greatly improving work efficiency.

2Vertical multipurpose oscillator for separating funnelInDetermination of residual content of insecticide ring in rice

GB/T 5009.113-2003 specifies the determination of pesticide content in rice by gas chromatography. InextractIn the experimental steps, the layered vibration of dichloromethaneThis experimental process can use a separatory funnel oscillator instead of manual oscillation.

GGC-C separating funnel vertical oscillator can be used.

GGC-CThe vertical oscillator (liquid-liquid extractor) of the series separating funnel can automatically shake the separating funnel to complete experimental processes such as liquid-liquid extraction and sample mixing; Large amplitude, fast speed, adjustable working time and frequency; Batch processing of samples, high efficiency, high recovery rate; Minimize the exposure of operators to chemical reagents and protect personal safety to the greatest extent possible!
