Product Overview
The Rectangular Water Bath is an electrically operated, high-performance laboratory device designed for gentle and uniform heating, crucial for temperature-sensitive procedures such as incubation, heating, and sterilizing. Constructed primarily from durable, thick stainless steel, these units ensure corrosion resistance and a long service life. All models maintain constant water levels and feature robust heating elements designed to provide uniform heating throughout the system.
Key Features and Construction
This rectangular water bath series is designed for optimum performance across various laboratory requirements, featuring specialized components for efficient operation:
• Durable Material: The inner chamber (and frequently the top cover and concentric rings) is constructed from high-quality stainless steel (SS) sheet, often specified as 304 grade.
• Capacity and Configuration: The standard size for the 6-hole model features chamber dimensions of 300 x 250 x 100 mm, offering a capacity of approximately 8 liters. The top cover is fitted with six removable concentric rings, each typically 75 mm in diameter, accommodating various flask or tube sizes.
• Thermostatic Control (Standard Model): The Single Wall model is typically controlled thermostatically, featuring a control knob and pilot lamps on the panel for easy manual temperature regulation.
• Heating and Safety: Heating is provided by fitted immersion heaters (sometimes Kanthal brand is mentioned) that ensure uniform heating. Certain models include an automatic cut-off device designed to activate if the bath runs dry, preventing damage.
• Drainage: The unit is supplied complete with a suitable drainage facility for quick water change and cleaning.
• Enhanced Functionality (Variations): Models are available in double-walled construction, utilizing insulation (like glass wool or special grade mineral wool) in the gap between the inner and outer chambers (often mild steel powder coated) to minimize heat loss and improve stability.
Versatile Applications
Rectangular water baths are essential equipment utilized across diverse scientific and institutional settings, including:
• General Laboratory Use: Ideal for routine tasks requiring constant, stable temperatures, such as condensing, distilling, soaking chemical agents, and warming samples.
• Medical and Research: Widely used in medical institutions and research laboratories, often specifically for sterilizing purposes.
• Biochemical and Agricultural Industries: Applications extend to bio-chemical industries, agricultural institutions, and educational institutes.
• Specific Procedures: Applicable for specialized heating protocols like Paraffin Embedding, and procedures such as Kolmer and Khan Test Inactivation.
