Laboratory Fume Hood Lattice and Its Uses
Lab apparatus, like lattice for fume hoods or benchtops are the backbone of a functional medical, research or university laboratory. A steady, strong frame assembly with the capability of changing structure quickly and almost effortlessly is essential for an efficient laboratory. Latticework is only as strong as its weakest part, so every element of the lab apparatus must work together to create a secure and reliable assembly for your important experiments.
No experiment is the same, so instead of wasting time re-arranging your lab for different tests, Lee Engineering makes it simple with our lab frame parts and kits.
From advanced manufacturing labs to grade school science rooms, latticework must be safe, robust, and easily manipulated. The words, strong and mutable would seem to contradict one another, but Lee Engineering’s years of experience have helped us create amazing products with both properties.
At Lee Engineering, we provide safe, quality lab apparatus parts and kits for all types of laboratories.
Lattice in Other Applications
Lattice doesn’t always refer to a laboratory apparatus set up. By definition, lattice can refer to:
- A structure consisting of strips of material crossed and fastened together with a square or diamond shape space between – like a fence
- An interlaced pattern or structure (a physical object or in algebraic applications)
- A three-dimensional arrangement of ions, molecules, or atoms – regularly repeated (physics definition)
Some of the common, three-dimensional lattice shapes defined in physics are:
- Simple cubic: a = b = c ⇔ α = β = γ = 90°
- Tetragonal: a = b ≠ c ⇔ α = β = γ = 90°
- Orthorhombic: a ≠ b ≠ c ⇔ α = β = γ = 90°
- Rhombohedral: a = b = c ⇔ α = β = γ ≠ 90°
- Monoclinic: a ≠ b ≠ c ⇔ γ ≠ α = β = 90°
- Triclinic: a ≠ b ≠ c ⇔ α ≠ β ≠ γ ≠ 90°
- Hexagonal: a = b ≠ c ⇔ α = β = 90° | γ = 120°
*See “Figure 1” (right) to help visualize each of the common three-dimensional shape

Lab Apparatus Frame: Custom-Made Or All-Inclusive Kits
Whether you’re looking to create a custom laboratory apparatus to fit your existing lab or you want to buy an all-inclusive kit, Lee Engineering has you covered. We don’t specialize in one type of lab experiment; we specialize in variety to meet your needs. We have the perfect components to build a custom apparatus for a large industrial chemistry lab or for a home laboratory for adults and children.
The applications of our lab frames are basically endless, but to give you an idea of where our products come in handy, we’ve compiled a list to of our most popular applications:
- Chemistry labs for large or small businesses
- Quality assurance labs for large or small businesses
- School science rooms, including chemistry and biology
- Medical research laboratories
- Government laboratories (forensics and more)
Parts Of Laboratory Lattice Frame Assemblies
Lab apparatus have five main components. They work together to create an area to conduct experiments and tests. These five main parts include:
Rods (usually aluminum or stainless steel) are the skeletons of your lab lattice, most often used as the base for suspending other components. Offered in various lengths and diameters, these versatile lab frame rods make setting up your lab simple.
Connectors allow the lab frame to be customized in just about any configuration you need. Our lab frame connectors are safe, easy to use, and durable.
Lab frame supports and bases give your lab frame a solid base to stand on. These can be free-standing with a fixed perpendicular base or secured to your lab bench with a locking single-plane base plate.
Lab Frame Clamps
Laboratory frame clamps secure various lab apparatus, such as jointed glassware, columns, flasks, and tubes.
Lab Frame Holders
Similar to clamps, ourlab frame holders secure beakers, test tubes, and other valuable equipment essential to your laboratory testing.
Uses Of Glassware In Chemistry And Other Scientific Laboratory Experiments
- Always make sure your glassware is clean before conducting an experiment.
- When measuring the volume of a liquid, always take the measurement at eye level with the bottom of the meniscus. The meniscus is the lowest point of the concave in the liquid.
- The letters “TC” (usually etched on the glassware) mean “To Contain”. This means the glassware you’re using contains the exact volume of the liquid you are measuring. However, when you pour it out, you will get less volume due to the amount of liquid sticking to the glass. Keep this in mind when choosing glassware for your lab.
- The letters “TD” (usually etched on the glassware) mean “To Dispense”. This means the volume of liquid you are measuring is more when it’s in the glassware, but when poured into another container, it’s exactly what you measured. Keep this in mind when choosing glassware for your lab.
Types and Uses of Scientific Glassware
Beakers are perfect for rough estimations of a liquid’s volume. Beakers are usually made from Pyrex and may be heated. When accuracy is essential, avoid using a beaker.
Burets are thin, long, and precisely calibrated columns of glass. They are marked in 0.1 mL increments from 0 mL to 50 mL. You should always be able to read between the marks to a precision of 0.01 mL. Always measure and record at this level - for example, a measurement should be recorded at 23.56 mL instead of 23.6 mL.
Mount burettes vertically using a clamp or a Lee Engineering burette socket.
Volumetric flasks contain an etched mark symbolizing a specific volume. They are used to prepare standard solutions and dilute samples to the etched volume.
The best way to fill a volumetric flask is to use a funnel or pipet. Fill below the etched mark, and then use a small, disposable pipet to fill until the meniscus is exactly at the etched line.
The standard deviation (tolerance) for volumetric flasks is generally as follows:
|Tolerance (± mL)||0.02||0.02||0.02||0.02||0.03||0.05||0.08||0.1||0.2||0.3|
For simple measurements of liquid, graduated cylinders are a great choice. Look for the etchings “TC” or “TD” to determine which graduated cylinder is right for your application.
Pipets use suction to transfer certain amounts of liquid from one container to another. They come in different sizes – large and small. In general, they are made in two different forms: (1) in glass form with a removable rubber suction control; and (2) in a disposable all in one design. Pipets are the perfect way to make precise measurements.
Storing glassware is an important topic touch on. To maintain the sterilization required in laboratories, clean, intact glassware is required. After washing, dry test tubes, culture tubes, flasks, and other glassware by hanging them on wooden pegs or placing them in baskets, mouths down, allowing them to air dry. Never put wet glassware directly into your lab’s casework. Once dry, store your glassware in labeled casework on a shelf, away from the edge. Labeling casework minimizes confusion and enhances laboratory efficiency.
