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.

The food calorimeter offers superior method of measuring the energy in foodstuff, compared to burning it under boiling tube of water. The enclosed vessel and copper tube ensure that more of the food's energy is used to heat up the water, and less heat is lost to the environment, increasing the accuracy of the experiment. The unit comprises glass jacket with bell jar inside. spiral copper tube draws air through the bell jar, in which food is burning, transferring more of the heat to the water. The lid has holes for thermometer and stirrer. The base unit (BI180105) has clips to hold the calorimeter unit securely, crucible holder, and posts for replaceable ignition coil. The bottom of the base has 4 mm sockets for connecting power supply to the ignition coil. A sample of food is placed in the crucible, the calorimeter unit placed over the top, and filled with water. The power to the ignition coil is turned on, and the food ignited. The temperature of the water is recorded, and the energy released can be calculated from the temperature change. To increase accuracy further, the calorimeter can be calibrated using spirit with known energy density. Also required: a 12 V power supply, 4 mm plug leads, a 0.1 g resolution balance and crucible. Please note that the calorimeter unit and base are sold separately, and both are required. Dimensions Body: (H) 215 mm, (H) including stirrer 275 mm, (D) 100 mm Dimensions Base: (H) 110 mm, (L) Retort Clamp 70 mm, (L) Total 170 mm, (D) 100 mm

PTC (pheylthiocarbamide) taste test paper test for the genetically controlled ability to taste this substance. Consisting of paper strips impregnated with a harmless quantity of test substance (or untreated in the case of the control strips), subjects will be able to detect (or not) varying tastes or degrees of intensity of taste. 1.Remove a PTC taste test paper from the vial. 2.Stick out your tongue and place the strip on your tongue. 3.There are three basic results: bland, bitter, or vile. The ability to taste these substances is known to be genetically linked (inherited) and depends on the presence of dominant or recessive genes. Having the ability to taste one substance does not necessarily imply that different substance will also be detected. PTC (phenylthiocarbamide) test strips have bitter taste for some individuals, the intensity of which can vary and depends upon a homozygous dominant or heterozygous condition in the individual. PTC Taste Test Paper is perfectly safe to use. Any possible toxicity of PTC would be in grams per kilogram of body weight, which is millions of times greater than anything which would be found in these taste test strips. Phenylthiocarbamide (PTC) is present at only 20 micrograms per strip. At this level, the compound is negligible and harmless.

This low-cost Label Remover gently removes pressure-sensitive labels easily and quickly without damaging surfaces. Sharp blade, use with caution.

Sodium benzoate test paper detects the genetic ability to taste Sodium Benzoate. The taste detected varies from sweet, salty, to bitter, depending upon the individual. Homozygous-dominant and Heterozygous-dominant individuals will detect the molecule. 1.Remove a strip of test paper from the vial. 2.Stick out your tongue and place the strip on your tongue. 3.You may not taste anything, but if you do, there are three basic results: sweet, salty, and bitter.

Thiourea test paper test for the genetic capability to detect Thiourea. For other taste tests, see our PTC and Sodium Benzoate test papers. 1.Remove a Thiourea test paper from the vial. 2.Place the test strip on your tongue and it will either taste bitter or it won’t taste like anything at all.
