Automatic molecular weight analyzer

Fully automatic viscosity analyzerIVS400-4

Product Introduction

IVS400 is an upgraded version of IVS300, which realizes functions such as continuous automatic cleaning, automatic measurement, automatic waste discharge, and automatic drying.

Applicable standard

Compliant with ISO1628 (except 1628-3) ASTM D4603、GB/T14190、GB/T17931、GBT35173-2017、GBT35262-2017、SNT1015-2001、GB/T1632、ISO307、ASTM D789、GB/T12006、HG/T2234、GB/T3401、GB/T12005、GB17514、GB/T28610、HG/T 2758、FZ/T 51008-2014 Pharmacopoeia and other international and domestic viscosity testing standards.

Main performance

1. Adopting modular design: The IVS400-4 series viscometer consists of one constant temperature water bath, one refrigeration unit, four measurement units, one main controller, two automatic sampling modules, and four viscosity tubes; Each measurement unit and the main controller work independently in a one-to-one manner, avoiding mutual interference during the measurement process;

2. The constant temperature bath adopts a dual compartment design, and the temperature control part and bath body of the precision constant temperature bath can be easily disassembled and separated, making it convenient to clean the mixing area of the bath; Constant temperature has high and low bath level alarm and over temperature protection functions;

3. Humanized design, the Ubbelohde viscometer can be replaced without draining the bath solution.

4. It has functions such as automatic sample injection, automatic temperature control, automatic measurement, automatic result output, automatic liquid discharge, automatic cleaning, automatic drying of viscosity tubes, and automatic stirring.

5. A powerful automatic sampling and cleaning system that can clean all the pipelines (viscosity tube, injection needle, injection tube, etc.) through which the sample passes.

6. The automatic sampler has 12 workstations, each equipped with an independent discharge pump, and the waste liquid collection is independent of each other.

7. The block pressing mode replaces traditional rubber cap connections, bidding farewell to the era where viscosity tubes were consumables and protecting the safety of experimental personnel.

8. Suitable for automated measurement and cleaning of Ubbelohde viscosity tubes.

9. Stainless steel infrared fiber, which can adaptively adjust the light intensity according to the sample. The service life can reach 10 years.

10. Cleaning module: integrated on the measuring unit, easy to operate, reduces maintenance difficulty and failure rate, and saves laboratory space. It can achieve independent automatic drainage, automatic cleaning, automatic drying, and soaking functions.

11. Waste liquid collection: Sample/cleaning agent waste liquid is automatically discharged into the waste liquid bottle, which can achieve waste liquid classification and recycling.

Performance Characteristics

Δ Dual mode online cleaning

There is no need to remove the viscometer, the waste liquid can be directly drained, and cleaning agents or the next sample can be added to rinse the viscometer;

When measuring continuously, replace the old sample with a new one, simulate manual cleaning method, and use high-frequency pulse type repeated automatic extrusion cleaning,

Immersion cleaning hover soaking, even the most difficult polymer can be cleaned thoroughly;

Reduced the frequency of exposure of experimental personnel to toxic chemical reagents, ensuring the safety of operators;

The single reagent dosage is 10-12ml, the rinsing volume is less than 12ml, and the remaining 13ml is used for measurement.

Δ Automatic addition of cleaning agent

Configure an automatic cleaning module with 1-3 types of reagents to choose from. After testing, it will automatically add cleaning agents, clean, drain, and dry.

Δ Intelligent waste liquid collection

No matter how many measurement units are selected, only one set of waste liquid collection device is needed to complete waste liquid collection; The classification and collection of waste liquid devices is conducive to waste liquid treatment and recycling, which is both economical and environmentally friendly.

Δ Software Function Integration

The measurement and cleaning functions are integrated into the same software, making it easy for experimenters to operate without switching.

Δ Small volume

The whole can be placed in a fume hood to reduce the toxicity of harmful reagent volatilization.
