Hyper filter prevents liquid overflow

Watson's "Hyper-Filter tip" adopts a special hydrophobic porous filter to prevent overflow caused by human errors.

 
Features of Hyper-Filter
1.Decreasing elution from the filter

Hyper-Filter has excellent chemical resistance, thus the sample which has been erroneously over-aspirated and touched the filter can be re-used in safety.

2.Stop sample overflow and contamination

In a comparison of Watson's Hyper-Filter Tips with other brands(when aspirating 60 µL with 20 µL filter tip), Watson brand Hyper-Filter tip completely prevents the sample overflow due to our highly dense filter in one minute after the solution has been absorbed.

3.Easy sample collection

The sample can be collected after aspirating the sample right up to the filter and dispensing.
The particles of filter do not swell with the solution and block the filter.

Watson HYPER-FILTER

Hyper-Filter can stop the liquid firmly but don't close the hole completely when it comes into contact with the sample excessively aspirated.

Hyper-Filter is dense enough to prevent overflow, however maintains the holes in the filter.

Conventional Hyper Filter

Conventional Hyper Filter particles, once the sample touched the filter, expand and block in the holes of the filter to prevent overflow.
These samples cannot be collected once dispensed.

Watson Tip System

 
SYSTEM RACK (PC)
SYSTEM RACK(PC)
Tough & extremely durable

The body and lid, made of polycarbonate (PC), does not lose its shape over time use. It can also be autoclaved repetitively.
Note: Repeated autoclaving may cause rack damaged.

SYSTEM RACK (PP)
SYSTEM RACK(PP)
Low cost and high chemical resistant

The body and lid, made of Polypropylene (PP) is lightweight, durable, and highly resistant to chemicals and heat. Because of its inexpensive cost compared with System Rack (PC), this System Rack (PP) can be disposed as one time use if used with non-sterilized long tip, or can be reused even after autoclaving if tips are manually refilled.
Note: The rack made of PP shrinks slightly after autoclaving, consequently refill plate cannot be used.
