Squeeze Bottles with Nozzle Cover

Style

Style D—Style D have a body made of HDPE, so they’re more rigid than bottles made from LDPE. You have to squeeze with more force, which gives you more control over the flow. The tip is LDPE, so you can cut it to the size you need.

Plastic Bottles for Harsh Chemicals

Style A

Our most chemical-resistant plastic bottles.

Style A

PTFE—PTFE bottles are more durable than fluorinated HDPE bottles. They won’t break down or leach contaminants, even when storing acetone, nitric acid, or other aggressive solvents. They’re often used for applications where purity is essential.

Glass Flasks

Tapered from a wide, stable base to a narrow neck, these borosilicate Erlenmeyer flasks reduce evaporation and direct vapors for easier collection. Borosilicate glass resists thermal shock and chemical attack for laboratory heating, mixing, and storage. A write-on label area lets you mark contents directly on the flask without adhesive labels that can degrade in chemical environments.

Plastic Bottles with Tamper-Sealable Lids


Tamper-Sealable Lid	LDPE

Stainless steel wire tamper-evident seals (sold separately) close with a seal press. Insert the end of the wire into the lock before sealing.

Secure a tamper-evident seal through the holes in the lid and bottle. If the seal is cut or broken, you’ll know the bottle has been opened.

Density Testing Flasks

Accurately measure the density of a liquid based on volume and weight. Also known as pycnometers, these flasks help you compare the specific gravity of a liquid to water. They’re often used for quality control in labs for food and beverage, pharmaceutical, or chemical manufacturing. Made from borosilicate glass, these flasks resist chemicals and won’t expand or contract from temperature changes. Use the included non-mercury thermometer to check the temperature of your sample—it's tested for accuracy, has small increments for precision, and is safe for shipping and handling. You can place these flasks in a constant temperature bath to control the temperature of the liquids inside.

To find the specific gravity of a liquid, divide the weight of the testing liquid by the weight of water at the same temperature.

50 ml Capacity—50 ml flasks help you comply with ASTM D153 testing standards for finding the specific gravity of pigments.
