Today, drawing123.com will guide you how to easily draw a beaker with simple steps.
Let’s get started!
Step 1: The Beaker’s Rim
Start by drawing a small, slightly flattened oval shape at the top center of your drawing area. This forms the very top opening of the beaker. Below this first oval, draw a slightly larger and thicker concentric oval ring. This creates the rolled rim or “lip” of the glass flask.
Step 2: Add the Neck
To form the neck of the flask, draw two straight, parallel lines extending vertically downward from the sides of the outer oval you just drew. These lines define the flask’s narrow throat.
Step 3: Sketch the Sloping Sides
Next, from the bottom points of the two vertical neck lines, draw two outward-sloping straight lines. These lines should flare dramatically downwards and outwards, forming the distinctive conical body shape of the Erlenmeyer flask.
Step 4: Close the Base
To finish the primary structure of the flask, connect the bottom ends of the two sloping conical lines with a single, wide, upward-curving line. This forms the curved bottom of the flask. The complete outline of the vessel is now visible.
Step 5: Add Measurement Markings
To turn this from a general flask into scientific equipment, add measurement graduations. On the right-hand sloping side of the conical body, draw a series of ten short, horizontal lines at regular intervals, which act as volume indicators.
Step 6: Define Liquid Levels
In preparation for coloring, define the surface and base levels for the liquid inside. In the lower-middle part of the flask, draw a wide oval. Then, inside the main curved base line, draw a matching curve just above it. This shows where the fluid is and defines its depth and surface.
Step 7: Apply Final Colors
The last step is to color your drawing. Fill the main conical body with a vibrant green to represent a chemical solution. Use a very pale, transparent blue to fill the glass walls of the flask and the neck, giving it a realistic glass appearance. The entire outline, mouth, and measurement marks should be finished in solid black lines to complete the professional illustration.
Step 1: Draw the Rim and Spout
Start by drawing a wide, squished oval near the top of your page. On the left side of the oval, extend the line slightly outward and bring it to a gentle point before curving back in, forming the pouring spout of the beaker.
Step 2: Add Vertical Side Walls
From the left side just beneath the spout and from the far right edge of the top oval, draw two parallel vertical lines extending straight down to form the sides of the beaker body.
Step 3: Connect the Curved Base
Connect the lower ends of the two vertical lines with a smooth, downward-curving line to complete the outer bottom outline of the beaker.
Step 4: Create the Inner Rim Detail
Draw an inner curved line just below the front edge of the top rim, following its contour. This gives the opening a realistic glass rim thickness.
Step 5: Define the Surface Line of Liquid
Inside the upper section of the beaker body, draw a flat, wide oval spanning between the two vertical walls to represent the top surface of the liquid inside.
Step 6: Outline the Inner Liquid Volume
Draw two straight vertical lines starting from the edges of the liquid surface oval, running parallel to the outer walls down to near the bottom. Connect them at the base with a curve parallel to the bottom of the beaker to complete the inner liquid container outline.
Step 7: Sketch Surface Water Ripples
Inside the top surface oval of the liquid, draw a few small, gentle wavy lines to suggest soft movement and reflections on the fluid’s surface.
Step 8: Draw the Measurement Scale
Add a measurement scale on the front center of the liquid body. Draw one straight vertical line, and attach five horizontal tick marks projecting to the right at equal intervals, with the top and bottom ticks being longer than the middle ones.
Step 9: Apply Final Colors
Fill the liquid inside the beaker with a vibrant pinkish-red color. Color the surrounding glass beaker with a soft, light blue shade to indicate clear glass, while leaving the black outline and measurement scale crisp and bold.
Step 1: Draw the Lip of the Flask
Start by drawing a small, horizontal rounded rectangle at the top of your drawing area. This forms the thick lip at the opening of the flask.
Step 2: Add the Long Neck
From the bottom edge of the lip, draw two straight vertical lines parallel to each other, extending downward to form the long neck of the flask.
Step 3: Draw the Round Base
At the bottom of the two neck lines, draw a large circle that connects to each side. This creates the spherical body of the round-bottom flask.
Step 4: Sketch the Liquid Line
Inside the round base, draw a smooth, wavy line horizontally across the middle to show the surface level of the liquid inside.
Step 5: Add Bubbles Rising Up
Above the opening of the flask, draw five small circles of varying sizes floating upward to represent bubbles escaping from the chemical reaction.
Step 6: Color the Flask
Fill the liquid at the bottom of the flask and all the bubbles above it with a bright blue color. Color the empty upper portion of the flask and the neck with a very light, pastel blue to represent clear glass, keeping all outlines crisp and black.
Step 1: Draw the Triangular Base Outline
Start by drawing a wide, open triangular shape with a curved bottom and rounded lower corners, leaving the top apex open.
Step 2: Extend the Vertical Neck
From the open upper ends of the diagonal lines, draw two short, parallel vertical lines pointing upward to form the neck of the flask.
Step 3: Create the Rim Collar
Draw a small oval ring around the top opening of the neck, curving slightly downward at the front to form the rim.
Step 4: Add the Stopper
Above the rim, draw a tapered cork stopper sitting in the opening, with a flat top and angled sides narrowing slightly down into the neck.
Step 5: Sketch the Liquid Surface
Inside the middle portion of the flask body, draw a flat oval across the center to define the top surface level of the liquid.
Step 6: Outline the Inner Liquid Boundary
Draw lines following the inner contour of the flask walls, starting from the edges of the liquid surface oval down along the sides and bottom curve to form the volume of liquid inside.
Step 7: Add Bubbles Inside the Liquid
Draw three small circles of varying sizes inside the liquid area to represent air bubbles floating near the middle and bottom.
Step 8: Apply Final Colors
Color the liquid inside the flask and its bubbles yellow. Fill the cork stopper at the top with brown, and shade the glass body and neck with a clear, light cyan-blue hue while keeping all outlines clean and black.
Step 1: Draw the Top Rim
Start by drawing a small horizontal oval near the top of your page to form the rim opening of the flask.
Step 2: Add the Upper Neck Lines
From the bottom edge of the oval rim, draw two short, nearly vertical parallel lines extending downward to begin forming the neck.
Step 3: Complete the Flask Body Outline
Continue the lines downward, flaring them outward into a wide triangular shape with rounded lower corners and connecting them across the bottom with a gentle upward curve.
Step 4: Draw the Inner Liquid Level
Inside the lower portion of the flask body, draw a flat oval across the center to define the top surface level of the liquid, and trace an inner contour along the bottom and sides to enclose the liquid volume.
Step 5: Add Bubbles Inside the Liquid
Draw several small circles of different sizes spread throughout the liquid area to represent floating gas bubbles.
Step 6: Draw Rising Bubbles in the Neck
Draw additional small circles rising upward through the neck of the flask above the liquid surface line.
Step 7: Apply Final Colors
Fill the liquid and all the bubbles inside and above it with a vibrant bright purple shade. Color the empty glass neck, rim, and outer glass border with a pale cream-yellow tint, keeping all outlines bold and black.
Step 1: Draw the Flask Rim
Start by drawing a small horizontal oval with rounded edges at the top center of the page to represent the lip of the flask opening.
Step 2: Add the Cork Stopper
Draw a rectangular cork shape inserting into the oval rim, with a small upper block extending above the rim and a matching lower block extending below.
Step 3: Draw the Long Neck
From the bottom edge of the rim, extend two long, parallel vertical lines downward to form the elongated neck of the flask.
Step 4: Sketch the Round Body Sides
At the bottom of the long neck, extend two large, symmetrical curved lines flaring outward to form the circular outer boundary of the spherical flask body.
Step 5: Flat Bottom Line
Connect the lower ends of the curved body sides with a straight horizontal line to form a flat, stable base for the flask.
Step 6: Draw Foamy Liquid Surface
Inside the main circular body, sketch a series of small, connected wavy arches across the middle to depict the foamy top surface of the liquid.
Step 7: Outline Inner Liquid Boundary
Trace an inner contour following the inside curve of the lower flask walls and bottom to define the enclosed liquid area.
Step 8: Add Floating Bubbles
Draw several small circles rising above the foamy liquid line, with some in the main body and others floating up into the long neck.
Step 9: Apply Final Colors
Color the liquid and all floating bubbles with a bright yellow-green shade, and fill the cork stopper at the top with orange. Color the rest of the flask interior and neck with a vibrant cyan blue, keeping all outlines clear and black.
Hopefully, this drawing tutorial on Beaker will help you easily create a nice drawing.
