Saline 37C Baths for Biomedical Testing - BB Series

OVERVIEW

BioBath Environmental systems are modular systems that are added to mechanical testing machines to enable tests of biological samples, biomaterials and medical implants in saline environments at 37C. The BioBath product line offers a complete modular package approach including test machine adaptors to enable their use on most test machines. Optional accessories include test grips, platens, fixtures, and extensometers. The bath chamber is acrylic and sized to match customer load frame, fixturing or test sample size requirements. Media temperature is tightly controlled with both static noncirculating and circulating versions available. Standard 37C test environments are commonly needed for testing medical and biological materials, products and implants. Common tests include static tensile, compression, flexural, fracture, peel and adhesion. Fatigue tests of implants are also common.

Product Features

The BioBath product line includes modular components and subassemblies to configure bath systems to application requirements. The products include baths, heaters, chillers, temperature controllers, circulating pumps, RTD's, and test machine adapters.

A broad selection of compatible test machine adapters, grips, platens, and fixtures are available.

The tank includes a split removable cover provided to minimize evaporative losses. The standard tank includes a silcone oring sealed door tightened with thumb nuts. Input and output ports for circulating pump and sensors.

A teflon sheathed RTD sensor is included and can be placed freely in the bath. In static (non-circulating) applications, two RTDs are provided and mounted in tank ports.

Medical implant fatigue testing applications tend to be more long term in nature and circulation of media is normally desired.

BB10-T200 Biobath Chamber with Temperature Control - Circulating Media

GA140 type stainless steel test machine adapters (2) couple the bath to test machine baseplates and load cells. The base adapter includes an O-ring seal with locking nut. The upper grip is normally attached to a pull rod assembly to the load cell.
