A utility clamp is a laboratory apparatus resembling a pair of scissors. The screw in the middle works as the wide adjustment of 2-prong. [1] It is composed of 3 parts: 2-prong adjust, metal rod, and clamp down (the clamp is attached to the ring stand for adjusting the height). This apparatus is connected to a ring stand or retort stand.
Burette clamp is a scientific equipment which used specifically to hold and secure a burette on a stand, so that a burette is fixed and more convenient for the experiment. [1] Burette clamps can be made with many materials such as plastic and cast iron. However, an iron clamp with a rubber knob to hold the burette are usually more durable.
In chemistry, gravimetric analysis is essential. After precipitating the chemical element of interest, successfully transferring all of the precipitate to the filtration funnel for separation from the supernatant liquid is required. This can be done by using a stream of distilled water from a wash bottle. This is less effective because dense ...
In chemistry, a retort stand, also called a clamp stand, [1] a ring stand, [2] or a support stand, [3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. [4] The typical ring stand consists of a heavy base and a vertical rod, both usually made of metal.
Iron rings used in a laboratory. An iron ring or ring clamp is an item of laboratory equipment which comprises a conjoined metal ring and radially-extending rod. [1] In some cases, the rod terminates in a screw clamp for attachment to a retort stand or other support; in others, the rod may be attached to a stand by means of a laboratory clamp holder. [2]
A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes.
Because of the round bottom, cork rings are needed to keep the round bottom flasks upright. When in use, round-bottom flasks are commonly held at the neck by clamps on a stand. A round-bottom flask is featured prominently on the logo of the OPCW, the implementing body for the Chemical Weapons Convention. [2]
The short tube and hose barb effectively act as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask.
