PYREX 3340-TO Replacement Adapter Tube with Standard Taper Joints

The PYREX 3340-TO Replacement Adapter Tube with Standard Taper Joints is a high-quality laboratory glass accessory designed as a replacement component for the PYREX 3340-500 Kjeldahl Nitrogen Distilling Apparatus. Manufactured by Corning from durable borosilicate glass, this adapter tube provides a precision connection between the Kjeldahl flask and Graham condenser during laboratory nitrogen determination procedures. The adapter features an inner 29/42 standard taper joint at the flask end and an inner 19/38 standard taper joint at the condenser end, ensuring compatibility with the corresponding components of the PYREX Kjeldahl distillation assembly. Designed for laboratory distillation, the adapter helps direct vapour from the heated Kjeldahl flask towards the condenser for subsequent cooling and collection. Its transparent glass construction offers convenient observation and excellent resistance to many laboratory chemicals. The PYREX 3340-TO is suitable for chemical analysis laboratories, food and feed testing facilities, agricultural research institutions, pharmaceutical laboratories, universities, and industrial quality-control laboratories. Important: This product includes the replacement adapter tube only. The Kjeldahl flask, Graham condenser and supporting clamps are sold separately.
