Laboy Glass 3-Way Distilling Thermometer Adapter with 29/42 Standard Taper Joints & Compression Cap, Borosilicate 3.3

The Laboy 3-way distilling thermometer adapter with 29/42 joints combines a distilling head and thermometer adapter in one compact piece of glassware. The bottom 29/42 joint is typically connected to a large distilling column or distilling flask, while the side 29/42 joint connects to a matching condenser. The top threaded opening accepts a compression cap and O-ring that seal around a plain-stem thermometer or bleed tube to form a vacuum-tight joint.3-way 29/42 joint configuration: Lower and side 29/42 standard taper joints at about a 75° angle create a convenient path from the distilling flask or column to the condenser in large-joint systems.Thermometer or bleed port: Compression cap at the top lets you insert a thermometer or bleed tube directly into the vapor stream for accurate temperature monitoring or venting.For large-scale distillations: Suitable for larger flasks and columns using 29/42 joints in organic synthesis and pilot-scale work.Borosilicate 3.3 and high-temperature annealing: Hand-blown heavy-wall borosilicate glass provides good chemical durability and resistance to normal thermal cycles.Standard taper & upgraded packaging: Interchangeable 29/42 joints fit other 29/42 glassware, and each adapter is shipped in an individual protective box to help ensure safe delivery.This 3-way 29/42 thermometer distilling adapter is ideal for large-joint setups in teaching labs, research labs and small pilot plants that require reliable temperature measurement and robust glassware.

• 3-way distilling head with thermometer port – Glass 3-way thermometer adapter that combines a distilling head and thermometer adapter in one piece, with 29/42 lower and side standard taper joints arranged at about a 75° angle for compact setups with large joints.
• The lower and side 29/42 joints connect flask and condenser – The bottom 29/42 inner joint is usually connected to a distilling column or large distilling flask for simple, steam, fractional or vacuum distillation, while the side 29/42 inner joint connects to a Liebig, West or air condenser sized for 29/42 joints.
• Compression cap thermometer joint – Threaded joint at the top with compression cap and O-ring to accommodate a plain-stem thermometer or bleeding tube, forming a vacuum-tight seal for accurate temperature measurement in the vapor path.
• Hand-blown borosilicate 3.3, high-temperature annealed – Made from high-quality borosilicate glass 3.3 with a heavy-wall design and high-temperature annealing to relieve internal stress; all joints use the standard 1:10 taper and are interchangeable with other 29/42 glassware of the same outside diameter.
• Protective individual packaging – Each 3-way thermometer adapter is individually packed in a protective inner box with cushioning material before shipment, helping the glassware arrive intact and reducing the chance of breakage during handling or FBA fulfilment.
