Respiration

Apparatus for measuring rates of absorption or evolution of gases from organisms. Comprises two stoppered boiling tubes with wire baskets to support organisms. Each boiling tube is connected to simple manometer tube via three-way tap. The manometer tube is mounted on scale to measure the position and movement of the liquid level as gas is evolved or absorbed. The organism of interest is placed in the basket of one of the tubes, which also has some potassium hydroxide solution to absorb carbon dioxide. The other tube acts as thermobarometer, to counteract changes in temperature. Full instructions are included.

Spare Wire Baskets for BI180500

Designed to measure lung capacity. Comprising of 4x graduated 6 L lung volume bags, holders and mouthpieces. Supplied with full instructions.

Replacement bags for CL04286. Comprising of 4x graduated 6 L lung volume bags.

Replacement plastic mouthpieces for lung volume kit (CL04286).

A simple stethoscope.

For testing inhaled and exhaled air. Consisting of two test tubes 150 24 mm, two lengths of glass tubing, connected by PVC tubing with plastic T- piece.

For investigating tidal volumes, respiratory rate, pulmonary ventilation, reserve volumes and vital capacity. Oxygen consumption can also be measured which is useful in metabolic rate studies. A simple lever control enables the subject to be connected either to the atmosphere or to the float for recording. A container for soda lime crystals is fitted which absorbs the CO2. The spirometer is designed to offer minimal resistance to airflow. This provides the user with greater comfort and ensures accurate results. The float is constructed from lightweight plastic and is calibrated in 0.5 litre steps with maximum capacity of 7 litres. A pen arm allows attachment of a fibre tipped pen for recording results or for attachment to a position sensor for datalogging. Two flexible corrugated breathing hoses 0.8 m long are provided. Supplied with two mouth pieces and noseclip. Complete with full instructions.

Pack of 100 spare mouthpieces for the Clifton Spirometer.

Disposable breathing filter for the Clifton Spirometer.

Translucent, natural colour sheet. Dimensions (L x W x D): 1 m x 1 m x 0.25 mm.

Kit containing all the necessary parts to make a lung model demonstration. Includes Bell jar, single hole bung, 'Y' shape adapter to fit in to bung, balloons, cable ties to hold balloons on to adapter, latex rubber sheet to attach to bottom of bell jar using rubber band (or string). By pulling down or pushing up the latex sheet, the balloons can be made to inflate or deflate, simulating the effect of the diaphragm on the lungs.
