12x20ml Angle Rotor

Introduction

Usages:

For enrichment of bacteria of cosmetics and disposable hygiene products.

Principle:

 Casein peptone and soybean peptone provide the nitrogen source, vitamins, and growth factors; sodium chloride to maintain osmotic balance; dipotassium hydrogenphosphate as a buffer; lecithin and Tween 80 can neutralize preservatives and can play a dispersed material in the emulsion features, lecithin can neutralize quaternary ammonium salt, Tween 80 neutralizes phenols, hexachlorophene, formalin, a combination that can neutralize and ethanol.

Formulation(per liter):

Casein peptone 17g

Soy peptone 3g

Sodium chloride 5g

Dipotassium hydrogen phosphate 2.5g

Glucose 2.5g

Lecithin 1g

Tween 80  7g

Final pH7.2 ± 0.2

How to use:

1.Suspend 38g in 1 L of distilled water , stirring heated to boiling until completely dissolved, distribute into flask,autoclave at 121 for 15 minutes.

2.Diluted and treated samples.

Storage: Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of 3 years.

The Acetic Acid GK format test kit is for use with auto-analysers and is suitable for the specific measurement and analysis of acetic acid (acetate) especially in wines, fruit juices, beverages and food products.

As part of Megazyme’s overall commitment to providing the highest quality products, we have developed this acetic acid kit that provides a specific and rapid assay for use with auto-analysers. The kit assay is based on the conversion of NAD⁺ to NADH and therefore provides a positive reaction (increase in absorbance) which offers a more robust assay.

The reagents, as supplied, are stable for a minimum of 2 years and the prepared reagents are stable for a minimum of 1 week (on-board stability). In addition, the prepared reagents can be stored frozen for longer term stability (see K-ACETGK Booklet for more details).
