"Tweezers?
Yes, but different"

 

Better Sensitivity. Better Performance. Better Results

You won't believe how easy it is to transform the way of manipulation with sensitive samples.

More sensitive than tweezers
Whether you work with seeds, sensitive tissues or living organisms, the gentle manipulation makes the difference between good results and perfect laboratory work.  GentleGrab presents specialized suction tweezers enabling the work even with particles of 150 μm to objects reaching up to tens milimetres. 

With GentleGrab you enjoy noninvasive manipulation by a dry way, with no worry about its potentional damage.

Touch the sensitivity
We developped GentleGrab laboratory tool with respect to missing technologies allowing noninvasive sample manipulation especially those of micro-scale size.

Gentle grip and precise placement of individual sample is now fully under your control. Secure as is the water adhession, more gentle than is the finest tweezer.

GentleGrab allows you to touch the samples by the most sensitive way - by air hand.

Example: Comparative seeding of Arabidopsis seeds by GentleGrab and Tooth-stick.
Both methods provides sensitive seed manipulation with minimal risk of seed coat or embryo damage (in contrast to tweezers). Seeds in both rows looks similar and for a first instance no difference is observed. GentleGrab provides sensitive seeding to both seeds and surface (compare surface shadows on image and inset). The quality of seeding is different, those seeds germinating under the surface (frequent case in tooth-stick usage) are not-optimal for real time growth analyzis and might influence total phenotypical traits.


Precisseness in detail
Details make the difference in between the good and perfectly performed experiment. The  steady hands are alpha and omega for laboratory presiceness and for the manipulation with objects smaller than 1mm this counts twice.

GentleGrab provides you the working comfort with minimal risk of sample damage, safely without touching the surface, where you need to place your sample.

 


Hands in comfort
Unique GentleGrab construction allows you to keep the steady hands.

The GentleGrab chassiss has been designed with care about the physiological handling. Specail two-positional sensitive trigger, optimal weight for non shaking hands and non-slip surface - all of these traits makes GentleGrab unique  and allows comfortable work with micro-samples in terms of hours.

Other benefits of using GentleGrab
GentleGrab is in here also to make the laboratory routine more comfortable. Unique features allows you to work with samples under optimal lighting, with better sample visibility while retaining the sample sterility. To achieve this, custom LED lighting, magnifier and 10μm size filters for sample safety are integrated.

The benefits of LED lighting are not just better sample visibility, however allows you to make things different and use GentleGrab for special purposes as is secure manipulation with plant samples under green lighting.

The GentleGrab safety with manipulation of semidry samples is ensured, based on the water adsorbents inside the H2O stop filter.


 

Working Range
GentleGrab allows you to grip, hold, place and spread samples with the use of sensitive air touch. Air based sample manipulation in constrast to other laboratory tools and approaches represents noninvasive approach (sensitive mnipulation, non-water use) and gives you unaffected results  once you are fixating samples or you wish to just sort and store material in its pure nature.

You can use GentleGrab under sterile experimental conditions as well as for the dirty work.

The work with gentleGrab is limited to dry and semi-dry objects.

Human Health

When developing GentleGrab tool, the eye protection has been important. Resolution limit of the eye depends on the contrast, brightness and number of observed details. If eyes stare for long periods at miniature objects under dim lighting, it forces them to work harder than usual. Despite its adaptability, human eye, unlike any optical instrument, might get tired easily. Above that, focusing on miniature objects tends to less frequent blinking. People usually blink about 18 times a minute and thus naturally refreshes the eyes. But people only blink about half as often while concern on reading or focusing of small objects. This can result in dry, tired and burning eyes and later on to focusing troubles and blurred or double vision symptoms. GentleGrab has been designed to prevent eye fatigue and possible described symptoms emergence. To achieve better contrast and optimal object magnification the LED light source is incorporated and removable magnifying glass is provided.
