Overview: The document provides detailed specifications and features of a complete line of water baths designed for scientific applications. These water baths are available in various models with both microprocessor and analog controls, offering precise temperature management and durability.

Specifications: The water baths come in different sizes and capacities, ranging from 6 to 20 liters for standard models and up to 99.7 liters for special applications. They feature a temperature range from ambient +5 to 90ºC, with temperature uniformity as precise as ±0.1ºC. The baths are constructed with stainless steel tanks and are fully insulated for heat retention.

Microprocessor and Analog Control: Microprocessor models (W6M, W14M, W20M) offer digital temperature control and display, ensuring precise management and safety with a backup temperature controller. Analog models (W6A, W14A, W20A) use a hydraulic thermostat and include a safety feature for overtemperature protection.

Reciprocating Water Baths: Models WS17 and WS27 provide precise temperature control with a reciprocating motion, suitable for applications requiring agitation. They include independent overtemperature safety and digital displays for temperature and oscillation speed.

Special Application Water Baths: Models WPC65, WPC75, WPC85, and WPC95 are designed for specific applications such as fecal coliform testing and large volume sample accommodation. These models feature microprocessor control and are recommended for use with stainless steel covers to maintain temperature uniformity.

Key Features: All models are designed with a unique warm air-jacket for uniform heating, recessed heating elements to prevent burnout, and electrostatically coated housings for corrosion resistance. Optional accessories include Erlenmeyer flask holders and stainless steel covers.

Electrical Requirements: The baths operate on 120V or 220V with single-phase cycles, and wattage varies by model and application.
