WPI's Nanoliter 2010 Microinjection Pump is ideal for many applications, including zebrafish, xenopus oocytes and drosophila. MICRO4, an optional microprocessor-based controller, can provide an "intelligent" and easy-to-use interface to up to four Nanoliter Injectors. Operating parameters are set with the membrane key-pad and LCD display.

More Info

The Nanoliter injector is a micro-processor controlled injection system that uses direct piston displacement. The collet assembly (exploded view) is shown in the image below. The glass pipette fits into the white, plastic sleeve (spacer). When the collet is screwed in place securely, the black rubber washers are compressed and hold the glass firmly in place.

As the plunger is depressed, it pushes into the glass to expel the liquid in the pipette. Eventually, the diameter of the plunger matches that...more

Eliminate the cost and trouble of making your own micropipettes — WPI can quickly supply your need for consistently sized pre-pulled glass micropipettes for injection of dyes or proteins into cells, oocytes and for many other biomedical laboratory applications. Tip diameters (ID) range from 0.1 to 10 micrometers. Micropipettes are available as plain shank or with luer fittings.

• Schott Duran borosilicate glass
• 0.5 micrometer and smaller ID micropipettes include an internal glass fiber for easy filling
• Tip inner diameter tolerance ±20%
• Short taper yields high strength
• Nominal length ≈ 50 mm
• OD:ID = 1.33:1
• Standard capillary outer diameters are 1.0 mm (thin-wall) or 1.14 mm
• Every pipette individually tested and inspected
• Vacuum packed

Silanized Tips (Luer Shank)

Silanization waterproofs the glass to retard water when inserting into cell. This will not let...more
