Metal ware items are commonly made of corrosion resistant metals or alloys, such as stainless steel, nickel, titanium, platinum, gold, iridium, etc. Plain steel items are also used, but due to its moderate chemical resistance they are more commonly used in areas where corrosion isn't that much of a problem or in consumable products. Brass and copper vessels are sometimes used in distilling ethanol from fermented fruits.
Similar to the glass and plastic type, they are used in vacuum filtration. Generally made of stainless steel or brass.
Useful for holding multiple burettes in a straight line. Often made of stainless steel.

Come in various sizes, in both diameter and length. While most types of needle have their base made of plastic, all-metal needles also exist. Long or very long needles are commonly used in air-sensitive methods, to transfer air-sensitive or even pyrophoric chemicals from their storage bottles to the reaction flask. Syringe needles are almost always made of stainless steel.
A tool consisting of a wire with a loop at one end, used mainly by microbiologists to retrieve an inoculum from a culture of microorganisms. The wire is made of platinum, titanium or nichrome.
Commonly used in the field of microbiology to transfer and inoculate living microorganisms, as well as biological cultures.
Used to fasten ground glass joints. Come in two forms, a flat metal strip form and a wire form (also called wire clip).
Used for holding glass reaction vessels.

Also known as pinch clamps, they squeeze the tube by default and to release it, you will have to press against the two heads releases the hose, which allows the fluid to flow through the tube.
Although metal mortar and pestles are uncommon, such items are sometimes used in pharmacies and in kitchen to grind very soft materials. Stainless steel is commonly used as construction metal. Such items are easy to scratch, which makes them unsuitable when grinding anything that has abrasive particles like sand. Full metal mortars are also very heavy.
Spherical joint pinch clamp are commonly used in holding the rotary evaporator collecting flask, as well as holding the filtration tube and fritted glass disk from filtration units.
Retort stands consist of a heavy metal base frame and a sole support metal rod placed vertically, most often welded to the base. They are commonly used as stands for holding clamps and bossheads. The heavy base frame can be either a flat piece of metal, an A-shaped frame, H-shaped frame, L-shaped frame, T-shaped frame or a tripod.
Used to cut soft materials.
Spatula-like scoop utensil used primarily in chemistry lab settings to transfer solids in lab.
Spatula is a stainless steel spoon-like item, consisting of a rod with one end cup-shaped, while the other end it generally flattened, though some spatulas come with both ends either flat or rounded. They are the most common and important lab metal item, widely used to transfer reagents from one bottle to a weighting scale or in a reaction vessel. Metal spatulas are incompatible with a variety of solid reagents, such as metal halides (wet or hydrated) or iodine, and if used in a flame, they should not be heated to the point of red-hot.
A type of metal can used for sterilizing medical and biological equipment. Sterilization is done in an autoclave.
All-metal syringe are commonly used in medicine and by vets.
Test tube brush
Used to clean test tubes and other tubular glassware.
Test tube holder
Similar in appearance to pinch tweezers, test tube holders are commonly used for holding test tubes when heating them.
Test tube rack
Test tube racks consist of one or two metal plates where circular holes are cut inside for the test tubes.
Useful to carry various fragile or heavy objects around. It's advised not to carry corrosive reagents, like acids or halogens with it.
A three-legged circular or triangular platform, made of carbon steel, stainless steel or aluminium, used to support or hold flasks, beakers or sometimes funnels during experiments. Often is used to hold a wire gauze in order to allow beakers and flasks to be placed on top of it, while a Bunsen or Teclu burner can be placed underneath to heat them up.
Alcohol burner stands are similar in construction, though they appear more like a miniature chair than a stand and have a heat resistant and fire-proof fabric.
Used to grab small objects.
A wire gauze is a wire mesh-like fabric with a ceramic or asbestos fabric woven in its middle.
Come in two main forms, cylindrical and square, are commonly used to hold glassware, most often when drying them in oven.
Also known as clamp holders, they are used to hold various metal rods and extension clamps, like iron rings or other utility clamps. Generally made of stainless steel, brass, aluminium or zinc.
Used for holding burettes. They generally have rubber knobs for holding the burette without scratching it. Often made of aluminium, but cast iron is also used.
Fisher burette clamp is a common model, due to it's simple construction and use.
Used to hold various glassware, especially odd form ones.
Used for storing cryogenic fluids.
Metal electrodes, made from zinc, copper, iron, nickel, tungsten, lead, titanium, either plated with platinum, rhodium, other noble metal or metal oxide are commonly used in electrochemistry.
Similar to screw clamps and bossheads, they are used to hold utility clamps in a hook like opening, which touches the support rod.
Iron rings are used for holding funnels or (rarer and not recommended) flasks. Some models have a built-in screw clamp, while others don't have one, but can be inserted in a screw clamp.
Some iron rings are open, which allow you to place the funnel on it without dripping potentially corrosive reagent on the metal ring.
A useful lifting device, which can be used to hold various flasks or installation at a desired height.
Some jacks also come with a support rod.
Useful when making a grid stand.
Round support plate
Used for holding heating mantles, Petri dishes or flat bottom flasks at a more elevated position.

Double jaw utility clamps are an interesting form of clamp which can be used to attach the said clamp on any large-diameter cylindrical objects, like pipes or bars.
Some utility jaws also come in models where you can adjust the angle of the clamp.
More advanced models have a flexible neck, similar to that used in desk lamps, often attached to a metal stand.
A vital tool for any metalworking.
Awls (bradawl, scratch awl, stitching awl) can be used as aid when making various wood or plastic lab equipment, either for marking or for piercing holes in them. They can also be used to break apart hardened reagents, though being short, an icepick would more suitable for this task.
Used for cutting boxes, paper, foam, thin wood and plastic.

Useful when closing tubing.
Removable tray shelving unit
Consists of detachable shelves which can also be used as trays.
Useful when wanting to sort bottles or other items on a shelf.
Useful for storing reagents, bottles, glassware, equipment, etc.
Slotted angle shelving units are commonly encountered.
Handling and storage
Metal items should be kept away from volatile corrosive reagents, as they are susceptible to rusting and corrosion.
They should also be kept in a different place from glassware, plasticware, ceramic and wood items, as there is a risk of damaging the former items if improperly handled. A tool cupboard is a good storage place, as is a tool rack.
When washing them, make sure you do not use acids, so avoid putting them in the acid bath after holding them in a base bath. Aluminium, brass, bronze, copper, steel and zinc items are incompatible with both washing bases, and organic solvents like acetone, alcohol (ethanol, isopropanol) or esters (methyl formate, methyl acetate, ethyl acetate) should be used instead to clean them.
