The AWS Student Kymograph is very reliable instrument for use in the study of physiology, pharmacology and Biological Science. There are two instrument model available and each is provided with a series of advance features. The instrument are available with or without stimulator. There is a range of accessories two suit most applications. Illustrated with the kymograph below is one suggested kit or assembly of the more popular accessories.
A general-purpose wedge-type Spirometer with a capacity of 9 liters. It is designed for teaching ‘A’ level, Medical and University classes the principles of Spirometry. It can be used in ascertaining: basal metabolic rate flowing exercise, Vital Capacity Subdivisions of Lung Volume Inspiratory and expiratory reserve volume, effect on ventilation of rebreathing CO2, hyperventilation effect on breathing patterns etc.
The walls of this bath are made of heavy, transparent plastic, so that the specimen can be consultant and easily observed. The tank is 100mm in diameter by 125mm high (4 x 5 in) and has a capacity of 800ml. Tank is solidly cemented to the base, which is constructed of formed white plastic. The plastic base offers the double advantage of not only being corrosion proof, but also serving as an excellent electrical insulator from the heater. A drain hole with tubing and plug is located in the bottom of the tank. There is also a tapered plastic cone in the bank bottom, into which the soft rubber bung carrying the stem of the glass tissue bath fits, making a convenient leak proof joint. The water bath is heated by a simple, sturdy cartridge element that is mounted off-center through the bottom on the tank. This heater has a rating of 50 watts. The temperature is controlled by an energy regulator mounted on the front of the bath. The dial has a position for “full energy” while the bath is being brought up to its desired temperature. A hole in three corners of the base can be used for uprights.
The Spirometer housing is made of heavy transparent plastic 6mm / 6.5mm thick. It measure 300 x 375 x 375mm overall ( 12 x 15 x 15 inch )
The 9 liter gas holder is made of light transparent plastic, and carries two needle points rest in metal dimples and serve as the pivot points for the gas holder.
The counterweight is free to move for adjustment on a Counter poise arm and, when adjusted, is locked in Place.
On the side corner of the gas holder there is a scale 130mm long (5 1/4 in). Graduated from 0 to 9 liters in 0.1liter increments. This scale is read by a metal point that can be adjusted for zero. This corner of the gas holder also carries a mounting for a writing pointer that can be used with a Kymograph or Chart Recorder.
The water chamber for sealing the gas holder has been reduced to the minimum capacity that allows easy clearance for the gas holder for the gas holder, and has a drain in its base with tubing and a plug.
The 30mm bore tubing for the airways, which is made of low density polythene, is light and strong. This tubing has extremely low- profile annular rings, which offers the minimum distortion on bending and therefore preserves the maximum cross-section area.
The mouthpiece is made of moulded soft rubber. It fits behind the lips, and has two soft rubber bites to locate the teeth and make it more comfortable for breathing through the mouth. The noseclip is also constructed of soft moulded rubber.
This instrument is supplied with a one-way valve that fits onto the mouthpiece. This valve ensures that the gas stream flows only in one direction. On inspiration, one valve opens and the other one closes, and vice versa on expiration. The valves are a new design and consist of thin mica discs mounted in cast plastic frame.
The mica disc is held at its center by a nickel plated brass threaded shank that has a soft stainless steel spring mounted on it. The mica disc moves against this soft spring and opens with the slightest positive pressure. It locks with slightest negative pressure.
The mouthpiece and tubing assembling fits to a tubing valve that is mounted in the side of the spirometer base. This tubing valve can be used for either an open or closed circuit. It has tubing attachments for one or two tubes on both the back and the front. It also has two ports to atmosphere. When the rotating handle is down, the mouthpiece tube or tubes are vented to the atmosphere. When the handle is rotated up, the mouthpiece circuit is connected into the spirometer circuit. This not only allows the subject to become accustomed to the apparatus with the tubing vented to atmosphere, but also allows an exact starting time to be determined for the experiment.
The soda lime canister is made of transparent plastic, and can therefore be used with a color indicating absorbent. The canister is 80mm in diameter x 125mm in length (3 ¼ x 5 in), and has a capacity of 600 ml. it mounts on a metal plate at the back of the spirometer, and can be connected in or out of the circuit by changing only one hose.
The walls of this bath are made of heavy, transparent plastic, so that the specimen can be consultant and easily observed. The walls are 6mm (1/4 inch) thick. The tank measure 140 x 215 x 155mm ( 51/2 x 81/2 x 61/4 ) and has a capacity of 4.7 liters.
The two sides of the bath are extended to form a stand. The heating control housing is made of white plastic, offering the double advantage of being corrosion proof and an excellent electrical insulator from the heater.
A drain hole with tubing and plug is located in the tank bottom and an overflow pope is mounted in the upper left edge of the tank, there is also tapered plastic cone in the tank bottom. Into which the soft rubber bung carrying the stem of the glass tissue bath fits, making a convenient leak proof joint. The water bath is heated by two simple, sturdy cartridge elements that are mounted through the fronts of the tank near the bottom and extend 50mm (2in) into it. These elements have a combined rating of 80 watts. The temperature of the water bath is controlled by a dial on the front panel that is graduated from 15 to 45 C, by 5 C increments. Inside the bath there is a metal tube that carries a sensitive thermostat sensing bead. This system maintains the bath within 0.5 C of the desired temperature once the bath temperature has stabilized. There is an indicator light in the front panel that glows when the bath is plugged into the AC line. There is also a second indicator light that glows whenever the heating circuit is energized. A screw-in fuse holder is also mounted on the front panel.

Labline LBL-D22 audiometer is a pure sound audiometer developed by using digital audiometry and
hearing aid testing and matching technology according to the acoustic principle. It is used for hearing
aid testing and matching for hearing assessment and physical examination centers, hospitals and other
institutions to detect the hearing threshold.
These popular Broome Restrainers provides fast and easy animal insertion. The cylindrical design of these Restrainers solves the problem of the rodents turning once they are introduced into the Restrainer.
To place the animal into the Restrainer, loosen white Derlin nose piece and grasp the animal by the tail. Slide the animal into the Restrainer by pulling its tail along the open groove until the animal is completely enclosed in the cylinder. Then slide the nose piece into the groove on the opposite side of the Restrainer and place it up to the nose of the animal.
