Y-Honey acidity rapid test reagent

Product introduction

Application

It is widely used in testing honey

Detection principle

Immature honey, high moisture content honey, processing, improper storage of honey and honey adulteration, under the action of the yeast fermentation of easily acid, can be identified according to acidity of honey is fermented or adulterated honey, honey the acidity is therefore an important indicator of honey quality merits. Honey acidity should be less than 40 (1mol / L NaOH) ml / kg. This reagent is suitable for rapid detection of acidity of honey.

Specification: 25 times.

Storage: normal temperature, avoid the sunlight.

Packaging: measured liquid: 1 bottle, color-developing reagent: 1 bottle.

Period of validity: 12 months.

Usage

Take 2.0g samples into the plastic cup, add 20mL pure water to mix, add 3 drops of color-developing reagent, the measured vertical droplet bottle is upside down and titration should be drip drop by drop, while adding while shaking, to appear pink (30 seconds does not fade), the record of the sample reagent consumption drops is V.

Results judgment

Honey acidity (1mol / L sodium hydroxide) ml / 100g = drops (V) * 0.287.

Number of drops measured droplets no more than 16 drops. Otherwise the acidity is below the mark.

Announcement

1. The test solution has corrosive, avoid for contacting with skin and mucous membranes, if straying into eyes, rinse immediately with plenty of water.

2. During titrating, should note orthostatic drop bottles to reduce the error. The determination of the amount of results with national standards or labels of the labeled amount is only 1 - 2 drops of the difference, should be carefully handled. It can be sent to the laboratory for accurate quantitative test.

3. This method is applied to on-site rapid test, specific test results according to the legal unit of the test results.

4. Scale with 3 ml plastic pipette, 1 ml is about 20 drops.
