Product Description

The straight condenser is the most fundamental condensation device in standard joint glassware, widely used in distillation and reflux operations. Its straight inner tube design offers simple structure, stable condensation efficiency, and excellent resistance to clogging, making it particularly suitable for atmospheric distillation and low-boiling solvent recovery. The standard 1:10 taper ground glass joint ensures reliable sealing and interchangeability with all standard joint accessories. Manufactured from borosilicate glass 3.3, it offers excellent thermal and chemical resistance. Effective lengths range from 100mm to 1000mm to accommodate various experimental scales.

Key Features

Borosilicate Glass 3.3: ISO 3585 compliant, low expansion, thermal shock 280°C
Straight Inner Tube: Simple structure, clog resistant, easy to clean
Standard Joint: 1:10 taper, precision ground for reliable sealing
Multiple Sizes: Available in 14#, 19#, 24#, 29# joint sizes
Multiple Lengths: 100mm ~ 1000mm effective lengths
High Transparency: Easy observation of condensation process
Chemical Resistant: Suitable for various organic solvents

Quality Assurance

Every condenser undergoes strict dimensional inspection, joint taper testing, and thermal resistance testing to ensure compliance with applicable standards.

Note: Ensure joints are clean and dry before use to prevent sticking. Cooling water should flow from the lower inlet to the upper outlet for optimal efficiency.

Applications

Typical Applications

Atmospheric Distillation

Solvent recovery, product purification

Reflux Reactions

Heating reflux, reaction condensation

Organic Synthesis

Various distillation and condensation operations

Solvent Recovery

Laboratory solvent recycling

Education

University chemistry lab teaching

Analytical Chemistry

Sample preparation, concentration

Compatible Equipment

Standard joint round-bottom flasks, three-neck flasks

Distillation heads, fractionating heads

Tip: The straight condenser is the most versatile condensation device with simple structure and clog resistance. 24# and 29# sizes are available in 1000mm extra-long length for large-scale distillation and high-efficiency condensation. Use accessories of the same joint size for optimal sealing.

Operation & Maintenance

User Guide

Preparation

Inspect condenser for cracks, chips, or scratched joints
Clean joint surfaces with a soft cloth or cotton swab
Apply a small amount of vacuum grease if joints are too tight

Installation & Connection

Connect the condenser to the distillation head or flask via the joint
Insert with gentle twisting motion, do not force
Secure the condenser with a clamp for stability
Connect cooling water: lower inlet → upper outlet, ensure correct flow direction

Condensation Operation

Turn on cooling water before heating, maintain steady flow
Select appropriate coolant temperature based on solvent boiling point
Observe condensate drip rate, adjust heating power accordingly
Monitor condenser outer wall temperature to ensure cooling efficiency
For extra-long condensers (1000mm), increase water flow rate as needed

Disassembly & Cleaning

Stop heating first, continue cooling water flow for cool down
Turn off cooling water, gently twist to detach
Clean immediately after use to prevent residue buildup
Wash joints with soft brush and detergent, avoid hard objects
Air dry after washing, store with soft paper between joints

Safety Tips

Ensure cooling water connections are secure to prevent leaks
Control temperature carefully when evaporating flammable solvents
Always work in a fume hood when handling hazardous chemicals

Do not

Do not use cracked or chipped condensers for experiments
For 1000mm extra-long condensers, ensure vertical installation to avoid bending stress
