Design: The solvent still head is an essential tool used in laboratory applications for distillation and collection of solvents. This particular still head features two 0-4mm high vacuum valves, which provide excellent solvent and chemical resistance, ensuring the integrity of the distillation process.

The still head is designed with a syringe port that has a 4mm PTFE stopcock and a 14/20 outer joint. The syringe port is used to remove the solvent from the flask during the distillation process. The 14/20 outer joint ensures a tight and secure connection to the rest of the apparatus.

The delivery port of the still head has a 14/20 inner joint, which allows for easy attachment to other laboratory equipment. The distance between the two joints is standard, providing compatibility with other laboratory glassware and apparatus.

Function: The function of this solvent still head is similar to the previous one, which is to aid in the distillation and collection of oxygen-free solvents in laboratory applications. However, there are some differences in the design and features.

This solvent still head has two 0-4mm high vacuum valves, which provide greater solvent and chemical resistance compared to the previous one. These valves allow for more precise control over the distillation process and can help prevent the loss of solvent.

Like the previous solvent still head, this one also features a syringe port with a 4mm PTFE stopcock and a 14/20 outer joint. This allows for easy removal of the solvent from the flask during the distillation process.

The delivery port of this solvent still head has a 14/20 inner joint, which is similar to the previous one. This allows for easy attachment to other laboratory equipment and ensures a tight and secure connection.

High-Quality Material and Craftsmanship: Laboy Glass uses high-quality borosilicate glass that is hand-blown and annealed at 800 degrees Celsius to increase strength and durability. The double manifold also features a heavy wall design with uniform wall thickness.

Guarantee: Laboy Glassware comes with a 100% 40-day money-back guarantee. If customers are not satisfied with their purchase, they can return the flask for a full refund, no questions asked. In addition, if the flask arrives broken due to shipping, Laboy Glass will replace it or offer a full refund.
