• DW-AA320N : Atomic Absorption Spectrophotometer

Features

• Built-in computer and LCD display: Integrated data processing ensuring stability and reliability. Functions include integral holding, peak height and area measurement, auto zero adjustment, deuterium lamp background correction, multi-linear and nonlinear curve fitting, display of parameters and calibration curves on screen, and report printing. Interface for external PC connection.
• Excellent stability: Double-beam system automatically compensates for light source and wavelength drift due to temperature variations and electronic drift, ensuring high baseline stability.
• Fast analysis: Hollow cathode lamp requires no long preheating. Samples can be analyzed immediately, ideal for multi-element rapid analysis.
• High measurement precision: Gas path system equipped with pressure and current stabilizers to maintain a stable flame and low noise. Finely focused light beam passes through the flame for high-precision analysis and low characteristic concentration.

• DW-K9860 : Kjeldahl Analyzer

General Description

The electric thermostatic water bath is a commonly used laboratory device for sample pre-treatment. It is widely applied in medical, chemical, biological fields, as well as in research institutions and laboratories.

The unit consists of an outer housing, a water tank, an electric heating system, and a temperature control system.

Working Principle

The temperature sensor converts the water temperature into a resistance value. After amplification and comparison through an integrated circuit, a control signal is generated to regulate the heating power effectively. This ensures that the water temperature remains constant with high accuracy.

Advantages

• Stainless steel tubular heating elements positioned horizontally.
• Perforated aluminum shelves for stable placement of laboratory containers.
• Top cover with interchangeable concentric rings suitable for different flask diameters.
• Side drain outlet for easy water discharge.
• High-quality temperature control system ensuring precision, reliability, and ease of use.
