Product Description
Mouth pipetting is never acceptable, and twisting a pipette into a stiff fitting is a common cause of breakage. This Heathrow Scientific safety bulb pipette filler offers a gentler approach, sealing around standard pipettes with a soft silicone adapter so you can draw liquid safely without forcing the glass.
This listing is for catalog number HS20623: Safety Bulb Pipette Filler, Red, Pack of 3. The natural rubber bulb holds 15 mL and is fitted with a white ABS attachment containing a conical silicone adapter. Because the pipette never touches hard plastic, the risk of cracking or chipping drops. An elastic band lets you hang the filler on a reagent bottle or your wrist. The red bulb measures 4.2 x 1.6 in and comes in packs of three. LIGHT LABS ships genuine Heathrow Scientific products with knowledgeable support from our Englewood, Colorado team.
