實驗室耗材及附件
■ KWIK-GARD 混合給藥器
•Specially packaged Sylgard 184 for quick and
easy application
•Coat patch clamp electrodes
•Make cell culture dishes and dissecting pads
Curing Time , 24hrs@25C, 15
min.@150C
Details Kwik-Gard is specially packaged Sylgard184 silicone for quicker and easier application,eliminating the messy procedure of preparing the mixture before
application. Its special cartridge controls the precise mixing ratio to ensure proper curing. The disposable tip mixes resin and hardener as they are
dispensed. Since no air is introduced during mixing, the resin does not need degassing for most applications. The mixed silicone is applied directly to
the site, reducing preparation time and material waste. Each Kwik-Gard cartridge contains 37 mL of resin and hardener. The dispensing tip has a dead volume of 0.75 mL.
■ 4886 High Performance Structural Epoxy 環氧結構膠
•Forms a strong and slightly flexible bond on plastic, metal, and glass •Bonds some low surface-energy plastics such as PEEK
Curing Time ,12hrs@25C
Details Probably still the best epoxy for bonding plastic, often used as the benchmark for testing the binding strength of other adhesives. The slightly
rubbery texture also makes it less easy to break off. It is the only epoxy known that can bond PEEK. Color: gray. Cures at room temperature.
Shipping Weight 1 lb. (0.5 kg)
■ 4898 Silver Filled Conductive Epoxy 銀環氧樹脂
•Use in wire bonding applications •Connect conductors that can't be soldered •Construct or connect Ag/AgCl pellets
Curing Time , 12hrs@50C; 5 min.@150C
Details Two-component silver-filled epoxy for electrical connections which cannot be soldered, such as Ag/AgCl pellets. This widely used silver-filled
epoxy features low viscosity and smooth flowing character. Pure silver is dispersed in both resin and hardener. Cures in 15 minutes at 120 °C.
Mix ratio 1:1. May be premixed and frozen for later use.
Shipping Weight 1 lb. (0.5 kg)
■ 7335 Carbon Filled Conductive Epoxy 碳環氧樹脂
•Construct carbon electrodes Curing Time 48 hrs@25C; 5min.@150C
Details Two-component carbon-epoxy, curable at room and elevated temperatures. Ideal for electrostatic discharge protection and EMI/RFI shield-ing. 1:1
mix ratio. May be premixed andfrozen for later use. Shipping Weight 1 lb. (0.5 kg)
■ 7128 RTV Sealant RTV 密封膠，非酸性
•Bond or seal electronics circuits (metal)
Curing Time ,72hrs@25C
Details Because it is non-corrosive, this material is ideal for use on metal, for encapsulating small circuits on connectors. After cure, will
withstand -55° to 200 °C. No mixing required.
Shipping Weight 1 lb. (0.5 kg)
■ 6820 Primer for Silicone 矽膠專用處理劑
•Enhances adhesion of silicone adhesives on difficult to bond plastic surfaces
Details Enhances adhesion of silicone adhesives to many difficult-to-bond plastic surfaces.
Shipping Weight 1 lb. (0.5 kg)
■ 1571 Room Temperature Vulcanizing Adhesive RTV密封膠
•Best adhesion property in this silicone family •Will bond many materials
Curing

Details
Clear silicone sealant provides good
bonding to plastic. After cure, will
withstand -55 to 200°C. No mixing required.
A handy, general purpose laboratory sealant.(Releases
acetic acid during curing.)
Shipping Weight 1 lb. (0.5 kg)
■ 13316 Mini Glue Gun with Glue Sticks 迷你膠槍及膠條
•Bonds wood, glass, metals, and many plastics •Easy to use for bonding and large gap filling
Curing Time as soon as it cools Includes: Three sticks of special formula hot melt glue. UL approved. 110V 60Hz only.
■ Kwik-Sil Adhesive Kwik-Sil 接著劑
•Live tissue and nerve studies •Medium strength adhesion
Curing Time , <5 min.@25C
Details The properties of this adhesive make it exceptionally useful for neuroscience applications, peripheral nerve studies and similar biomedical applications.
These new silicone elastomers also eliminate the mess and time involved in pre-mixing other commonly used formulations (such as Wacker SilGelR and SylgardR).
Each silicone elastomer is packaged in a double barrel syringe and is automatically mixed when pressed out of the mixer tip provided. It can then be applied
directly to the tissue without further mixing. The curing time of these silicones is short, reliable and reproducible thus eliminating potential costly
guesswork when using other tissue adhesives. Furthermore, the curing process does not produce heat, which can otherwise cause tissue damage. WPI's silicone
elastomers are much less toxic than dental silicone because they contain no surfactant additives. Toxicity WPI's silicone elastomers are based on recently developed vinyl terminated siloxane and platinum complex catalysts. They exhibit exceptional low toxicity
before, during and after curing. The traditional RTV silicone systems produce either acetic acid or alcohol during condensation; these compounds are toxic
to living cells.In contrast, the only by-product of condensation from WPI's elastomers is a small amount of hydrogen gas, which was shown not to cause any
effect on nerve activity in highly sensitive peripheral nerves. Both elastomers cure on contact with the tissue. Currently,WPI provides rapid-curing silicone
elastomers in two different formulas:Kwik-Sil is a translucent silicone elastomer adhesive with medium viscosity. It has good adhesion and mechanical property
(tear strength and elongation). The very short curing time (approx. 1 minute) make it especially useful for moving preparations.

silicone elastomers in two different formulas: Kwik-Cast is a very low viscosity silicone elastomer sealant. It is able to fill small spaces around nerves
and creates a continuous mass ensuring long-term recording stability. Kwik-Cast is color-coded so mixing is foolproof. It can be applied and cured
underneath mineral oil. The slight longer curing time (approx. 3 minutes) makes it more suitable for stationary preparations and in vitro tissue studies.
