Two Necks Parallel Adapters
Precision-Aligned Vertical Geometry: Engineered with two parallel sockets to allow for unhindered mechanical stirring alongside simultaneous instrumentation, ensuring universal compatibility with standard taper modular components.
CNC-Ground 1:10 Taper Interfaces: Features automated matte-finish joints specifically calibrated to maintain hermetic, leak-proof seals under fluctuating atmospheric pressure and extreme chemical temperature gradients.
₹390.00
Quick answer: This Two-Neck Parallel Adapter fits onto a single-neck flask to provide two vertically aligned sockets, allowing a stirring rod or condenser in one and simultaneous reagent addition or another operation in the other, without needing specialized multi-neck glassware. Two Necks Parallel Adapters is priced at approximately ₹390 (indicative market benchmark, incl. GST, August 2026).
This adapter converts a standard single-neck flask into a two-opening setup with both sockets vertically aligned in parallel, which is useful when two straight-down connections are needed at once — for example a stirring rod through one socket while a condenser sits in the other, or simultaneous reagent addition alongside reflux. Made from borosilicate glass with ground glass joints, it provides a vacuum-tight, airtight connection suited to organic synthesis procedures where a single-neck flask alone wouldn’t offer enough access points, common in college and research chemistry laboratory setups.

Applications
- Organic synthesis reactions requiring simultaneous stirring and condensation
- Reagent addition alongside reflux without specialized multi-neck flasks
- College and research chemistry laboratory setups needing extra flask access points
- Expanding single-neck flask capability for multi-step procedures
Care & Maintenance
- Grease or fit PTFE sleeves on ground glass joints to maintain a reliable vacuum-tight seal
- Clean thoroughly after each use to prevent residue buildup at the joints
- Inspect joints for chips regularly, since a damaged joint compromises the seal

Frequently Asked Questions
What does this adapter allow that a single-neck flask can’t do alone?
It adds a second vertically aligned socket, allowing two straight-down connections at once — such as a stirring rod and condenser, or reagent addition alongside reflux.
What joint size does this adapter use?
Exact joint size has not been independently verified for this listing — confirm compatibility with your flask with STEMAids before ordering.
Is this suitable for a college organic chemistry lab?
Yes — two-neck parallel adapters are standard equipment for organic synthesis procedures needing extra flask access points.
How does this differ from the vertical-and-angled two-neck adapter?
This version has both sockets aligned vertically in parallel, while the vertical-and-angled version offers one straight socket and one angled socket for different access needs — choose based on your setup.
Does STEMAids supply matching flasks?
Contact STEMAids to confirm current availability of compatible single-neck flasks for use with this adapter.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
