Product catalog summary

Company Overview
CHC LAB Co., Ltd., founded in 1996, specializes in laboratory furniture, fume hoods, and equipment. It joined SEFA in 2007 and holds certifications from Korean Standard and NSF/ANSI standard 49. The company serves sectors such as government, education, and pharmaceuticals, focusing on sustainable lab-safety technology.

Safety and Quality Assurance
CHC LAB prioritizes safety, adhering to standards like NSF/ANSI 49 and EN12469. Their biological safety cabinets ensure safe research environments with certified performance.

Biological Safety Cabinet Features
The cabinets include a wide intake grille to prevent cross-contamination, ergonomic design to reduce fatigue, and a differential pressure gauge for monitoring. They feature utility valves, electrical receptacles, and a sash alarm for safety, while minimizing glare and energy consumption.

HEPA Filter Efficiency
HEPA filters achieve 99.995% efficiency for particles of 0.3㎛, surpassing standard requirements. The filtration system uses impaction, interception, and diffusion principles to enhance efficiency.

Control System
The control system manages operations such as power, blower, and lamp settings, and includes features like a paper catch, air velocity display, and alarm functions for filter and UV lamp maintenance.

Biological Safety Levels and Cabinet Classifications
CHC LAB's cabinets support biosafety levels 1 to 3, offering protection for personnel, products, and the environment. Classifications include Class I, Class II A2, Class II B2, and Class III, each with specific airflow and protection features.

Model Specifications
Models like CHC-100 and CHC-111A2 offer features such as power supply options, UV lamps, and exhaust systems. They are constructed with materials like stainless steel and include safety systems like UV timers and alarms.

Overview: This document details specifications and features of three Biological Safety Cabinet models from CHC LAB: CHC-222A2, CHC-777A2, and CHC-888B2, designed to protect researchers, products, and the environment by filtering and managing airflow.

General Specifications:

Power Supply: All models operate on 110/220V, 50/60Hz.
