Fully automatic sample dilution instrument

Product Introduction

DW-JURAY Series Fully Automatic Sample Dilution InstrumentCompliant with GB 4789 National Food Safety Standard Microbiological Examination, international standards ISO 6887-1, ISO 7218, it can automatically achieve accurate dilution of samples of any weight, and is used for automatic dilution of microbial samples in food, medicine, cosmetics and other pre-treatment processes, simplifying the work.

Example of dilution

Dilution requirement: 25 g of microbial sample+225 mL of sterile physiological saline.

Automatic dilution: With the DW-JURAY automatic weight dilution instrument, you only need to set the dilution ratio (1:10) and add the sample. You don't need to weigh it accurately to 25g. Press a button to automatically add the diluent to the sterile sample bag (homogenization bag) in proportion, achieving precise dilution of the sample to be tested.

DW-JURAY Series Fully Automatic Sample Dilution InstrumentProduct advantages

1. Safety Design: Integrated Casting Waterproof Safety Design for Instruments

2. Multi point work: The instrument weighs only 6.5 kg, with a built-in high stability balance that supports easy handling on different workbenches in the laboratory

3. Intelligent calculation: The weight of the sample in the sample bag is uncertain, but the instrument can automatically add diluent according to the dilution ratio without manual calculation

4. User friendly interface: programmable settings, simplified operation of the instrument through touch panel commands

5. Traceability: Experimental data is stored in the built-in microprocessor, and dilution programs can be customized; Exportable print records include: date, time, operator number, sample number, sample weight, dilution factor, diluent number, total weight

6. Aseptic assurance: The diluent only passes through the sterilized separation pipeline, avoiding contamination of the diluent and sample. Equipped with detachable trays for easy cleaning

Large screen LCD display
