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 measuring units, one main controller, one PC workstation, and four viscosity tubes. Each measurement unit and the main controller work independently in a one-to-one manner;

2. Constant temperature bath:

Adopting a dual compartment design, the inner and outer shells are made of stainless steel material, and the double-layer visible tempered glass windows. The temperature control part of the precision constant temperature bath and the bath body can be easily disassembled and separated; The constant temperature zone adopts a dual temperature sensor design, with high and low bath level alarms and over temperature protection functions;

3. Humanized design:

The Ubbelohde viscosity tube can be replaced without draining the bath solution.

4. High degree of automation:

Each measuring unit independently completes operations such as automatic temperature control, automatic measurement, automatic timing, automatic calculation, automatic drainage, automatic cleaning, and automatic drying of viscosity tubes.

5. Block pressing mode:

Suitable for various types of Ubbelohde viscosity tubes, dilution Ubbelohde viscosity tubes, trace Ubbelohde viscosity tubes, etc., replacing traditional rubber cap connections, bidding farewell to the era where viscosity tubes were consumables, and protecting the safety of laboratory personnel.

6. High performance configuration:

Equipped with imported lift pumps and armored stainless steel infrared fiber sensors, it is more suitable for automated measurement and cleaning of Ubbelohde viscosity tubes.

7. Cleaning module:

Each cleaning module is separately integrated on the measuring unit, making it easy to operate. It can achieve independent automatic drainage, automatic cleaning, automatic drying, and soaking functions.

8. Dual mode online cleaning:

No need to remove the viscometer, the waste liquid can be directly removed, and cleaning agent or the next sample can be added to rinse the viscometerClean all the pipelines through which the sample passes;

During continuous measurement, new samples replace old samples, simulating manual cleaning methods. High frequency pulse based automatic squeezing cleaning, immersion based cleaning, hovering soaking, and even the most difficult to clean polymers can be cleaned thoroughly.Reduced the frequency of exposure of experimental personnel to toxic chemical reagents, ensuring the safety of operators;

9. Automatic cleaning agent addition function:

The DX10 automatic liquid dispenser can simultaneously complete the operation of automatically adding cleaning agents to each measuring unit, with 4 types of cleaning agents to choose from.

10. 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. Each waste liquid bottle is equipped with a liquid level sensor to detect the amount of waste liquid and a full liquid reminder function.

11. Software function integration:

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

12. Reserve LIMS interface to support experimental data upload and unified management.

13. Small volume:

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