Description
Product Introduction:
The photolithographically engraved acid burette (Laser Brown, Class A, EX) is a high‑precision, chemically resistant, and high‑temperature‑tolerant core laboratory measuring instrument, specifically designed for the accurate titration and volumetric analysis of acidic and strongly oxidizing solutions. It features high‑borosilicate glass and laser‑etched graduations, complying with Class A metrological standards and the EX (delivery) calibration specifications.
Application scenarios
1. Chemical analysis: volumetric analysis, including acid–base titration, redox titration, complexometric titration, and precipitation titration.
2. Research and Teaching: Precision metrology and experimental teaching in university and research institute laboratories.
3. Industrial Inspection: Quality control and compositional analysis in industries such as food, pharmaceuticals, environmental protection, chemicals, and electronics.
4 Standard Metrology: Calibration of standard solutions and traceability of measurement values by metrological institutions and third-party testing laboratories.

YLZ-100 Microcomputer-Controlled Electro-Hydraulic Servo Curbstone Flexural Testing Machine
The YLZ-100 concrete curbstone flexural‑compressive testing machine is used to determine the flexural strength and flexural load of linear curbstones with a length of 1000 mm, as well as the compressive strength of curved curbstones and L‑shaped curbstones with a straight cross‑section. In accordance with JC/T 899‑2016 Concrete Curbstones, it can also be employed to conduct experimental studies on the flexural and compressive strengths of other materials.
The microcomputer-controlled high‑ and low‑temperature electronic universal testing machine consists of the testing machine mainframe, fixtures, a high‑ and low‑temperature chamber, and computer software. The temperature chamber is slid into the mainframe; after opening the chamber door, the specimen is secured in the dedicated fixture. The chamber then heats or cools until the specified temperature is reached.
