Circulating water bath LSRB series

agitatinglaboratorywith cooling system

Usage:
LSRB series circulating heating and cooling magnetic stirring reaction water baths provide controlled low- and high-temperature environments for flasks, beakers and test tubes. They are intended as an alternative to dry ice or liquid nitrogen for low-temperature reactions and for precise high-temperature thermostatting. Typical users: hospitals, research laboratories, universities, enzymology and biological labs, quality control and identification facilities.

Characteristics:

• Digital temperature setting and display with selectable ranges.
• Fully enclosed magnetic stirrer for stable, contamination-reduced mixing.
• Optional built-in dual stirring to maintain uniform specimen temperature within reaction vessels.
• Adjustable slot cover opening to reduce refrigerant consumption.
• Lever fixture for securing burettes, probes and auxiliary devices.
• International-brand compressor for high reliability and efficiency.
• Convenient bath fluid port for fast replacement of bath medium.

Standard Type:

• Blue LCD control panel.
• 5-stage program control for up to five timed operations.
• Remote communication port for computer connection.
• Temperature over-limit alarm and protection functions.
