A bicycle frame is supported by a wooden stand, from the front of which two uprights ascend and carry a desk and cross piece, which provide for the attachment, directly in front of the subject, of the tension balances and other pieces in front of the subject, of the tension balances and other pieces of apparatus. A cast iron wheel of 5 1/2 feet in circumference, weighing 22 Kilos and mounted on ball bearing, is substituted for the back wheel. This wheel has slightly beveled edges and is turned true. To the circumference of this, a stout calico is applied, and the two ends of the band ate attached to spring balances of 6 lbs. range (Graduated in one oz.) calico-band to the balance pass round adjustable pulleys in order to give them the right direction. An adjustable record counter records the revolution of the wheel.

Semi Automatic electric operated having filling cap. 50 to 300ml. Complete stainless steel body.

Electrically operated with 6 tubes

Digital Display, these are designed to provide light effects for multipurpose viewing in bacteriology, virology & Mycology labs. An ideal instrument for counting bacterial and mould colonies in culture work. It provides uniform flare free illumination to minimise the strain on eyes and clearly defines even small colonies. A 100mm dia lens covers the entire illuminations field and its magnification assures highly accurate results. Counting plate with standard wolfhugel ruling ensures clealy differentiated and sharply defined colonies. Supplied complete with counting plate, lens, cord and plug.

The apparatus consists of 4 parts. A water bath with 500 watt heater covered 1000ml. Vessel made from Borosil Glass and digital temperature control. Variable speed motor, with 30 cms longs stainless steel shaft. A cylindrical stainless steel basket and a membrane fixing attachment, water bath is made of imported thick acrylic sheet with transparent cover at top. Temperature of the bath is maintained at 37°C with an accuracy of ±1°C. A cylindrical glass vessel of 1000ml capacity with slightly concave bottom has a flenged edge at the top to accept a fitted cover having four holes. One hole placed in the centre. The shaft of the motor is fitted on an up right and has an electronic speed regulating device that allows the speed to be varied from 25 to 250 RPM. The shaft is 6mm dia 30cms on with basket fitted at end rotates smoothly and without any significant wobble. The basket consists of two parts one of which is attached to the shaft. It is of solid metal except for 2mm vent and is screwed on the main shaft. Lower part of the basket is held with this part by means of threading and this allows proper removal of lower part for introduction of the test samples. The detachable part of the basket is fabricated of stainless steel mesh formed into cylinder of size 36mm x 25mm dia. The equipment is workable on 220 volts 50 C/s A.C.

A perspex organ bath with fine thermostatic temperature control, electric stirrer and complete set of accessories, making it a versatile unit for all research work. Bath 12"x9"x8", with leak proof dovetailed joints, resting in sturdy metal frame; top of the bath carries a 1"x3/8" thick band, for fixing accessories, inside the bath is a metal sheathed heating element (easily replaceable) controlled by means of a fine adjustable thermostat with sensitivity ±1°C. The stirrer unit is completely independent and dips in the bath in one corner, fixing on its special stainless steel upright. A M.S. junction box is fitted to the bath frame and carries all the electrical leads and connections, two pilot lamps indicate functioning of the thermostat and stirrer.

Available in five models

Used to determine the durability and abrasivness of tablets. A transparent perpex drum (made of imported perspex sheet 6.4mm thick ) 300mm dia x 35mm deep and white cover disc and nut, also a shaped radial fixed blade which carries the tablets along with it up to the central height and lets them off while the drum is rotating. Thus the tablets rub against each other without any hard impact. The drum rotates at a fixed speed of 30 RPM by a geared motor and the rotation period is controlled by a timer (imported time switch duration of 1 to 15 minutes) per determined end preset. The motor unit is housed in a shaped steel cabinet with shaft extended on one side upon which the drum rotates. Switches with neon indicators and time switch are fitted on a panel and provided work on 220 Volts 50 C/s AC. Digital models also available.
