VERNIER MICROSCOPE, SIMPLE (TRAVELLING MICROSCOPE)

A simple microscope tube with a rack and pinion arrangement for focusing is attached to a vertical carriage supported on a brass pillar. The vertical column itself is mounted on a transverse carriage sliding horizontally on a metal rod in the base along the horizontal scale. The horizontal as well as vertical scales of stainless steel. Both carriages can be moved along their respective scales for approximate setting of desired positions after releasing their locking screws, finer adjustment of the carriage position being made with the fine adjustment knob at the end of each slide. The carriages also have vernier with a least count of 0.01 mm and provision for attaching a swing-out magnifier for reading the vernier. Microscope tube is adjustable both vertically as well as horizontally and has a Ramsden eye-piece with cross-line graticule. Complete assembly mounted on a heavy cast metal base with leveling screws which has a removable flat horizontal stage for positioning the sample/object under observation. The complete unit is packed in polished wooden case.

WATER STILL, WITH AUTOMATIC SHUT OFF

WATER STILL, WITH AUTOMATIC SHUT OFF

A fully automatic, electrically heated, wall mounting, Manesty type water still, designed for continuous use, for distillation of water to produce high purity, pyrogen free water. The undistilised water enters ower end of the tube, circulates around the condenser tube and ultimately filling the boiling chamber to a height predetermined by means of a weir. The descending steam in the condenser tube thus pre-heats the ascending column of raw water and expels gases dissolved in it, venting them to the atmosphere. The steam generated in the boiling chamber passes through a system of baffles. The baffles are so arranged that the vapours change direction three times before passing into the condenser tube. The boiling chamber, condenser pipe and tube, weir assembly and inner baffles are made of stainless steel. The outer lid and inner baffle cup being made of clear glass. The whole unit can be easily disassembled for regular maintenance, cleaning and scaling. Electric elements are fitted with resettable protective cutouts. Includes brackets for wall mounting. Operates on 220-240V AC, 50Hz. Includes 3core mains detachable cord. Output capacity about 4L per hour.
