Dipping Probes

Overview

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

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.

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 

 

Specifications

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.
