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.
Do you export to North Africa?
Yes, Lab Glassware Manufacturer regularly exports laboratory glassware and fittings to Morocco, Algeria, and Mauritania, and can quote FOB or CIF terms on request.
