PTFE Needle Valve Stopcock Straight
Product Code : EL-GS-10273
Quick answer: This straight-pattern PTFE needle valve stopcock gives fine, gradual flow control in an in-line configuration, with a corrosion-resistant PTFE needle available in 0-3mm and 0-6mm bore sizes, and no lubricating grease required.
| Bore Size (mm) | Configuration | Key Material |
|---|---|---|
| 0-3 | Straight (in-line) | PTFE |
| 0-6 | Straight (in-line) | PTFE |
Dimensions follow standard specifications.
Straight vs. 90-Degree Needle Valve Configuration
An in-line, straight-pattern needle valve suits manifold and distillation setups where the flow direction does not need to change, whereas the standard PTFE Needle Valve Stopcock is configured with a 90-degree outlet for burette-style dispensing. Both configurations use the same corrosion-resistant PTFE needle for fine, drop-wise flow adjustment without lubricating grease.
Frequently Asked Questions
What does "straight" configuration mean here?
The inlet and outlet are in line with each other, rather than at a right angle, making this variant suited to manifold or distillation-line installation.
Which bore size should I choose?
The 0-3mm bore suits fine metering and drop-wise addition; the 0-6mm bore suits faster, higher-volume flow.
Is the PTFE key resistant to laboratory solvents?
PTFE resists most common laboratory acids, alkalis, and solvents; buyers with an unusual reagent list should confirm compatibility before ordering.
