Radical Instruments

Ambala Cantt, Ambala, Haryana

Adding to the existing range of Radical jugs, these short from transparent jugs, made of polypropylene are autoclavable and have non-drip spout. These jugs have raised graduations, provide excellent contact clarity & are provided with excellent thumb grip on handle.

Polished brass, in hardwood case with hinged lid. Divided compartment with dust cover holds nickel-silver and aluminum fractions. With chrome plated brass forceps.

For specific gravity, shot loaded, sub-divided in 0.002mm. Overall length approx. 250mm. Range 0.80mm to 1.00mm adjusted for low surface tension, others adjusted for medium surface tension.

To demonstrate the Bernoulli effect produced by water flow. Comprises a Bernoulli tube, with central constriction, a constant bore gradient tube, 6 length glass tubing, 2 swan-necked outlet tubes and 8 pre-cut lengths of rubber connecting tubing. The 2 flow tubes, each 500x13mm, length 25mmx150mm spacing, extended to form 500mm manometer with the lengths of glass tubing.

For simulated molecular activity in gases. To understand and study motion and behavior of molecules in gases. An electric motor, running at 4 to 12 V DC vibrates a small platform inside a transparent tube so that a set of many small stainless steel balls is vibrated violently inside the tube. An increase in the violence of vibration simulates an increase in gas temperature and an increase in the weight of the 'float' simulates an increase in gas pressure. Supplied with balls and 2 'floats'.

The case is made of aluminium, strongly mangetised cobalt steel needle fitted with imported hard axle rolls on knife edges agates and can be clamped when desired by a V clamp, a sensitive spirit level is provided. The tripod stand is provided with three levelling screws.

The plastic ring or bobbin, 162.5 mm overall diameter wound with three coils of insulated copper wire with 2, 50 and 500 turns mounted on bakelite moulded platform fitted with 4 terminals, rotating on a tripod non-magnetic metal base, supported by levelling screws. Complete with compass box (Magnetometer) mounted at the centre of the ring.

To demonstrate that charge resides only on outside surfaces of a conductor. Sphere of 5 cm. diameter on insulated stand, complete with hemispherical cups, having insulated handles.

This is a robust instrument designed specifically for student use which is capable of very high performance. The main structure is of heavy cast metal, with bright plated fittings.Scale : The 150 mm. diameter circle with protective shield is fixed to the telescope movement and the table is attached to the double ended vernier which reads to 1 minute of arc. Both telescope and table rotation fine adjustment screws, and release of a clamping screws enables adjustment of both movements to be made by hand.

Collimator : Mounted on fixed and fitted with 178 mm. focus achromatic objectives, 25 mm. clear aperture. Also fitted is a unilaterally adjustable slit, 7 mm. long.Telescope : Mounted on moveable pillar and fitted with 178 mm. Focus achromatic objective, 25 mm. clear aperture. Also fitted is a 8x Ramsden eyepiece and a glass crossline graticule. Both the telescope and collimator have rack and pinion focussing. Means are provided for levelling the axis of both optical units and for squaring them to axis of rotation.

Heavy duty cans made of high density polythene. With carrying handle at the top, screw cap and side tap for outlet. Available in different capacities:

Light weight and easy to handle. These bottles are moulded in Polypropylene, which is autoclavable, dependable and have good impact strength providing extra durability to the bottle. The leak-proof spigot is screwed to the bottle body and requires only a half turn to open or close providing quick and convenient dispensing. It is acid and alkali resistant and can be used for storing and dispensing solutions, media and distilled water. Can be autoclaved, when empty, to prevent recurring bacterial growth. Available in different capacities:

Moulded in polypropylene, these superior quality beakers feature excellent clarity and very good chemical resistance, autoclavable, with permanent graduations. Tapered spout facilitates easy pouring out. Available in different sizes are given below:
