Import Tips
• Include lab safety certifications (UL/CSA) and voltage specifications for FDA-regulated research equipment
• Declare as 'electrophoresis apparatus' specifically to avoid reclassification as general lab power supply
• Provide technical specs showing programmable output modes unique to electrophoresis processes
