Abstract: A culture flask 10 comprises two or more internal chambers 18-21 defining a plurality of parallel surfaces of different sizes and means for fluid communication 24 between the chambers 18-20.

Abstract: A sample tube 1 is provided for insertion, in use, into an SBS format rack. The sample tube comprises a polypropylene body 11 with an internal metal coating 3 and a glass lining or coating 2 disposed on the metal coating.

Abstract: A system for monitoring temperatures in textile finishing operations includes a temperature sensing device (10). The device includes a module (40) therein which is operative to capture data corresponding to temperature sensed at a thermocouple (48) as the device moves through a tenter frame (54) in engagement with a web (22) of textile material. The data captured by the device is transmitted to a computer (62) and visually perceivable outputs corresponding to temperatures recorded can be output through a display (66) and/or a printer (68). Data may also be output real time and may be used to adjust operating conditions in the tenter frame through communication between the computer and a controller (60) which controls temperature and/or air flow within the tenter frame.
