Smallest Fiber Optic Dipping Probe

Small volume measurements made simple with the Mini DipTip™ microliter sampling probe.

 Mini DipTip™s  outer diameter is only 1.5 mm—the size of a 17-gauge needle. It will fit into all micro centrifuge tubes on the market and is a useful tool for measuring protein and DNA samples. The diminutive dipping probe can also be used for a dissolution system.

Microliter samples can be analyzed cost effectively when you combine the Mini DipTip with one of the following:

• The Fiber optic-based spectrometer (Tidas-E Base Series Photo Diode Array Spectrometer) and a light source (D2H and FO-6000)
• A spectrophotometer (Tidas S300 Series e.g. pn 505067)

The Mini DipTip is ideal for multi-channel applications.

• Compatible with fiber optic spectrometers, fiber optic light sources, and fiber optic spectrophotomers (SMA 905)
• 2, 5 and 10mm light pathlengths available

Applications

• Protein and DNA sample measurements
• Dissolution system

Mini DipTip™ is a miniature transmission probe for microliter spectroscopic sampling. Mini DipTip’s tip diameter is only 1.5 mm—the size of a 17-gauge needle. It will fit into all micro centrifuge tubes on the market. Microliter samples can be analyzed cost effectively when you combine the Mini DipTip™ with one of the following:

• TIDAS E Base with FO-6000 or D4H
• LEDSpec
• TIDAS S300 series
• Compatible with most fiber coupled spectrometers
• Ideal for multi channel applications with LEDSpec 

DipTip Mini Instruction Manual

DNA samples (with a sample volume of 50µL inside mini centrifuge PCR vials) were measured in PBS with concentrations between 0 and 43µg/mL using a Tidas 100 spectrophotometer.

Tip Diameter	1.5mm
Light Pathlength	2, 5, 10mm
Wavelength Range (nm)	200-1000
Sample Volume Required	20-50µL
Distance From Tip to Upper Edge of Sample Window	7mm
Fiber Length	1.0m
Fiber Optic Connection	SMA 905
Launch Fiber Bundle (7 x 200µm) NA = 0.22	Ø=680µm*
Return Fiber Bundle (7 x 200µm) NA = 0.22	Ø=680µm*

*Circular packaging of the fiber bundle results in an active area equivalent to a fiber with a core diameter of 680µm. Using a 600µm connection is recommended and will result in negligible light loss.

Connect the fiber optic connectors to the spectrometer and the light source. Hold the Mini DipTip by the handle. Do not bend the tip.
