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.

Control Systems:

• Microprocessor Models: These models offer digital set/read temperature control, ensuring rapid heat-up and precise temperature management. They include a backup temperature controller for added safety.
• Analog Models: These models use a hydraulic thermostat for temperature control and include an internal safety feature to prevent overheating.

Design Features: The water baths are designed with a low silhouette for easy loading, rubber supports for stability, and a powder-coated exterior to resist corrosion and damage. The unique warm air-jacket design ensures uniform heating without hot spots.

Reciprocating Water Baths: Models WS17 and WS27 offer precise temperature control with a reciprocating shaking motion. 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 constructed with double-wall stainless steel for enhanced durability.

Accessories and Recommendations: Stainless steel covers are recommended for achieving maximum temperature and uniformity. Optional accessories include Erlenmeyer flask holders. Distilled water is recommended for use in all models.

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