Steel Strips For Resonance
The resonance strips are designed to demonstrate the relationship between the frequency and wavelength of a cantilevered beam. The steel strips when used with the Vibration Generator show resonance at different frequencies The resonant frequencies of resonance strips depend on the different lengths of the strips. The apparatus provides three steel strips with holes at different length and connected with one another through a screw

Stereo Microscope, Inclined, Model SM 505
Stereo-microscopes are required where an image of high quality, erect, magnified and with full preception of depth is needed. These are designed to have a long working distance and three dimensional viewing to facilitate mechanical interaction with the specimen e.g. in dissection of small specimen, study of living organism, study of rocks and minerals, inspection of electronic and other small components.
* 45° inclined binocular head for ease of observation, fitted with precision prism system.
* Interpupillay distance is adjustable 50-75 mm with independent compensating adjustment on the left eye tube.
* Focussing is by large knobs on both sides by rack and pinion arrangement.
* With removable white/black plate in base with stage clips.
* Eyepieces : WF x10 (paired)
* Objectives : Achromatic x2 (paired) and x4 (paired) with sliding arrangement.
* Magnification : x20, x40
* With dust cover.
* In moulded styrofoam box or in wooden box.SKU: B10508 - Uncategorized

Stereo Microscope, Model SM 511
This is an ideal stereo microscope which provides a crisp, erect image over a wide field of view. The transmitted and incident illuminations assure the best results. Stereo binocular head is inclined at 45° for ease of viewing, is rotatable through 360°and can be locked in any position. Interpupillary distance is adjustable 50-75 mm.
* Independent compensating adjustment is provided on the left eye tube.
* Focussing is by rack and pinion system.
* Illumination is through two tungsten lamps which provide transmitted and incident light. One is fitted below the translucent stage plate in the base and the other near the objective turret. The illuminators may be used either individually or simultaneously through a selector switch. A built-in transformer is also provided in the base. Operates on 220V 50Hz mains supply.
* Eyepieces : WF x10 (paired).
* Objectives : x2 (paired) and x4 (paired) mounted on a quick changing turret which keeps the specimen in focus on hange of objectives. The objectives are parfocalised and recentered
* Magnification: x20 & x40.
* Supplied in moulded styrofoam box or in wooden box.SKU: B10510
