Manufacturer: Drop Technology

Product name: TLDA Microvolume Spectrophotometer

Microvolume (sample size = 1–4 µL) UV–vis spectrometer

New this year: Instrument based on Drop Science technology

Used for: Lab analysis

Dimensions: 454 × 250 × 330 mm (D × W × H)

Weight: 11 kg

Measurement mode: Drop Science technology

Specialty accessory description: Wavelength range 200–750 nm. Technology used is unlike other microvolume instruments. The drop under test sits on a quartz plinth, without any disturbance, while the measurement is being made. Removal after measurement is simple: just wipe the sample from the quartz. Is also available stand-alone (see Accessories).

Special features: Only a small sample volume (1-4 µL) is required. Can be used where larger volumes and dilution may be required. Very fast (milliseconds) measurement. Pulsed xenon light source (no lamp needing regular replacement). Good for high-value samples.

Software: Available as separate product, cGMP compliant

Suggested applications: dsDNA, ssDNA, RNA, protein quantification

Primary benefits: Ease of use, lack of cross contamination from one sample to another and the ability to calibrate the instrument using NIST traceable standards. Because of our technology, accuracy and reproducibility can be achieved in all application areas.

Unique features: Sample loading and removal for either right or left handed operation. Quick and simple sample chamber opening and closing.
