New Generation of Pressure Injectors

• MICRO-ePUMP - Microinjector with Integrated Cell Penetrator and Internal Pressure Source 
• μPUMP - Microinjector with Internal Pressure Source
• PV850 - Microinjector for Use with External Pressure Source*
• All pneumatic microinjectors should be used with long-tapered micropipettes for optimal functionality. Check our our pre-pulled long-taper tips here

*If you currently have either the µPUMP or PV850 and are interested in adding electroporation fuctionality to your system, check-out our MICRO-ePORE™.

Type	MICRO-ePUMP	uPUMP	PV850
Regulated compensation and injection pressure
Pressure output: 0.01–87 PSI
Low volume tubing assembly
Inject using foot switch (included)
Inject using a TTL pulse from external computer or pulse generator (Cable to connect to pulse generator included)
Inject manually using touch screen interface
Integrated pressure source
2-Stage foot switch to activate voltage for injection and MICRO-ePORETM
Integrated MICRO-ePORETM Technology  Audio continuity tone indicating active probe Injection counter to indicate total number of injections User-adjustable frequency and voltage through touch screen

Benefits 

• Intuitive user-interface, with touch screen and tailored knob adjustments
• Small footprint for optimized bench space
• High precision for reproducible injections – picoliter to microliter scale
• All inclusive system (tubing, footswitch, capillary holder with various gasket fittings)
• Plug-and-play system: little-to-no preparation required to begin working as quickly as possible
• Compensation pressure feature omits capillary action for complete control over your sample 
• Option to use a range of micromanipulators with both with our standard 6.35mm pipette holder, and the slimmer 4mm holders, commonly paired with hydraulic or manual manipulators. 
• Premium Warranty Available

Applications

• Microinjection of diverse compounds and biomolecules (e.g. cell transfection)
• Nanobead production/calibration for emulsion-based studies in drug development

All Your Microinjection Accessories

Let WPI be your one-stop shop for all your microinjection needs. We offer any accessory you may need alongside your microinjector, from microscopes, manipulators, to pre-pulled glass pipettes. 

(1) MICRO-ePUMP

(3) PV850

(3) Microinjector with External Pressure Source (pressure source not included).

Timing, injection pressure and compensation pressure are adjusted inde­pen­dent­ly using the touch screen interface. Time intervals can range from 10milliseconds to 2 seconds, where the injection pressure interval is triggered by using a foot switch, computer-controlled TTL pulse, or by manual selection on the unit display (MICRO-ePUMP uses only a foot switch or manual trigger selection).
