Utility Clamp
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. 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. It is used to hold round laboratory glassware, such as beakers Beaker may refer to: Containers * Beaker (drinkware), a beverage container * Beaker (laboratory equipment), a glass container used for holding liquids in a laboratory setting * Beaker (archaeology), a prehistoric drinking vessel * Beaker culture ..., and flasks, etc. This type of clamp is made from stainless steel.

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both aluminium and copper, having a biological cleanability comparable to glass. I ...

Scissors
Scissors are hand-operated shearing tools. A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are intended for cutting and trimming foods such as meats. Inexpensive, mass-produced modern scissors are often designed ergonomically with composite thermoplastic and rubber handles. Terminology The ...

Screw
A screw and a bolt (see '' Differentiation between bolt and screw'' below) are similar types of fastener typically made of metal and characterized by a helical ridge, called a ''male thread'' (external thread). Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar ''female thread'' (internal thread) in a matching part. Screws are often self-threading (also known as self-tapping) where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevents pull-out. There are many screws for a variety of materials; materials commonly fastened by screws include wood, sheet metal, and plastic. Explanation A screw is a combination of simple machines: it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane (thread) also comes to a sharp edge around the outside, which acts as a wedge as it pushes into the fastened material, and th ...

Retort Stand
In chemistry, a retort stand, also called a clamp stand,Laboratory-Equipment.com (2020):Large Clamp Stand, for Q700. Online catalog item 5323-07. Accessed on 202-02-18. a ring stand, or a support stand,Fischer Scientific (2020):American Educational Products Tripod Base Support Stands Online catalog entry S47809. Accessed on 202-02-18. is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. The typical ring stand consists of a heavy base and a vertical rod, both usually made of metal. A number of accessories, such as clamps of various types and iron rings, can be attached to the rod by thumbscrews, at whatever heights and orientations are necessary to support the target equipment. Structure Retort stands commonly have a cast iron base of around 200 x 125 mm. The rod may be up to 750 mm and screws into a female thread in the base. The height of the rod is sufficient for most exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glassware
upTypical drinkware The list of glassware includes drinking vessels (drinkware) and tableware used to set a table for eating a meal, general glass items such as vases, and glasses used in the catering industry. It does not include laboratory glassware. Drinkware Drinkware, beverageware (in other words, cups) is a general term for a vessel intended to contain beverages or liquid foods for drinking or consumption. * Beaker * Beer glassware * Coffee cup * Cup * Jar * Mug * Pythagorean cup * Quaich * Sake cup (''ochoko'') * Stemware * Teacup * Trembleuse * Tumblers The word ''cup'' comes from Middle English ''cuppe'', from Old English, from Late Latin ''cuppa'', drinking vessel, perhaps variant of Latin ''cupa'', tub, cask. The first known use of the word cup is before the 12th century. Tumblers Tumblers are flat-bottomed drinking glasses. * Collins glass, for a tall mixed drink * Dizzy cocktail glass, a glass with a wide, shallow bowl, comparable to a normal cockta ...

Beaker (glassware)
In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom.Oxford English Dictionary 1989 edition Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight rather than sloping sides. The exception to this definition is a slightly conical-sided beaker called a Philips beaker. The beaker shape in general drinkware is similar. Beakers are commonly made of glass (today usually borosilicate glass), but can also be in metal (such as stainless steel or aluminum) or certain plastics (notably polythene, polypropylene, PTFE). A common use for polypropylene beakers is gamma spectral analysis of liquid and solid samples. Construction and use Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter.British Standard 6523 (1984) ''Glass beakers for original expe ...

Laboratory Flask
Laboratory flasks are vessels or containers that fall into the category of laboratory equipment known as glassware. In laboratory and other scientific settings, they are usually referred to simply as flasks. Flasks come in a number of shapes and a wide range of sizes, but a common distinguishing aspect in their shapes is a wider vessel "body" and one (or sometimes more) narrower tubular sections at the top called necks which have an opening at the top. Laboratory flask sizes are specified by the volume they can hold, typically in metric units such as milliliters (mL or ml) or liters (L or l). Laboratory flasks have traditionally been made of glass, but can also be made of plastic. At the opening(s) at top of the neck of some glass flasks such as round-bottom flasks, retorts, or sometimes volumetric flasks, there are outer (or female) tapered (conical) ground glass joints. Some flasks, especially volumetric flasks, come with a laboratory rubber stopper, bung, or cap fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
