Laboratory Equipment

A pH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH.

Why is pH measurement and control a problem? pH electrodes have been around long enough to be well understood and readily applied. The problem is since pH is a logarithmic function, a change of one pH unit represents a ten-fold change in hydrogen ion concentration.

what does pH stand for?

The term pH is derived from “p,” the mathematical symbol for negative logarithm, and “H,” the chemical symbol for Hydrogen.

pH is a unit of measure which describes the degree of acidity or alkalinity of a solution. It is measured on a scale of 0 to 14.

Neoprene filter adapters are designed to fit between a filtering funnel and a flask. For use with Buchner funnels, Gooch crucibles, filter tubes, etc. Can be used individually or nested with adjacent sizes. Eliminates the boring of rubber stoppers and the difficulties of inserting and removing glass…

A heating mantle, or isomantle, is a piece of laboratory equipment used to apply heat to containers, as an alternative to other forms of heated bath. In contrast to other heating devices, such as hotplates or Bunsen burners, glassware containers may be placed in direct contact with the heating mantle without substantially increasing the risk of the glassware shattering, because the heating element of a heating mantle is insulated from the container so as to prevent excessive temperature gradients. Heating mantles may have various forms. In a common arrangement, electric wires are embedded within a strip of fabric that can be wrapped around a flask. The current supplied to the device, and hence the temperature achieved, is regulated by a rheostat. This type of heating mantle is quite useful for maintaining an intended temperature within a separatory funnel, for example, after the contents of a reaction have been removed from a primary heat source.
