PM-854 PRESSURE TUBING GREEN

Suitable for laboratory pharmaceutical and Industrial use as it can o o be used over a temperature range of - 50 C to + 250 C. Used for transfer of hot liquids; can be sterilized by steam or by hot air so useful under aseptic conditions. Odorless tubing, does not impart any smell or taste to the liquids passing through it, so well suitable for transfer of pharmaceutical liquids, beverages and other food preparations. High grade, superior, silicon rubber is used for making this tubing so not irritant to skin. Highly elastic, so well suitable for use, with peristaltic pump. These are transparent to translucent. Silicon rubber tubing should not be used with strong acids, strong alkalies, carbon tetrachloride, bromine and toluene. Cat.

PM-855 SILICON RUBBER TUBING

An easy to use, accurate, instrument calibrated horizontal and vertical planes both measures to 0.01 mm. For measurement of two axes e.g. to determine the real and apparent depth of a liquid. Microscope carriage supported on a brass column with engraved graduations, can be positioned on either side of column for user’s convenience. Vertical column is mounted on the traversing carriage that moves along the horizontal scale and has a swing-out magnifier for reading the veriner. Cast iron base, has a removable glass stage plate, and is fitted with three levelling screws. Both carriages can be moved along their scales for approximate setting of positions, after releasing their locking screws. Fine adjustment of the carriage is by fine-thread screw at end of each slide. Microscope tube which is focused by rack and pinion, can be set vertically or horizontally and is fitted with a glass cross line graticule and an eyepiece in a draw tube. Supplied in a polished wooden case Technical Specification Scale- Horizontal 0-17 Vernier reading to 0.01 Scale-Vertical 0-120 vernier reading to 0.01 Optics Eyepiece x7 Ramsden Optics Objective x3, focal length 50 mm.
